I am able to set the image and text for button. But it is aligned horizontally. I want the image and text to be aligned vertically inside the button. i.e., text below the image
How to make these changes using storyboard?
What I want is this:
What I am getting now is this:
If you are looking for output like this
1) Select button and go to Attribute Inspector in your storyboard to get this result of Button size 50*50
2) Now set Title Insets of Button
I've written an extension that do the works for you, Swift 4 compatible.
public extension UIButton {
func alignTextBelow(spacing: CGFloat = 6.0) {
if let image = self.imageView?.image {
let imageSize: CGSize = image.size
self.titleEdgeInsets = UIEdgeInsetsMake(spacing, -imageSize.width, -(imageSize.height), 0.0)
let labelString = NSString(string: self.titleLabel!.text!)
let titleSize = labelString.size(withAttributes: [NSAttributedStringKey.font: self.titleLabel!.font])
self.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + spacing), 0.0, 0.0, -titleSize.width)
}
}
}
Where spacing is the distance between image and text.
Yes you can do it from storyboard without writing any logic also.
1) Select button and go to Attribute Inspector in your storyboard.
2) Assign Image to the button. (Don't use background Image)
3) Set Title text to that button.
4) Now you need to set edge and Inset so first select image from edge and set Inset as you need and then select title from edge and set inset as per your need.
Hope this helps.
You can easily and visually achieve the alignment using the Edge property of the Button from Property Window(Attribute Inspector) you can change the inset values of Title, and Image as per your need, see image below
Hope it helps.
Cheers.
Swift 4.2 compatible code is here , you just need to call this function
public extension UIButton
{
func alignTextUnderImage(spacing: CGFloat = 6.0)
{
if let image = self.imageView?.image
{
let imageSize: CGSize = image.size
self.titleEdgeInsets = UIEdgeInsets(top: spacing, left: -imageSize.width, bottom: -(imageSize.height), right: 0.0)
let labelString = NSString(string: self.titleLabel!.text!)
let titleSize = labelString.size(withAttributes: [NSAttributedString.Key.font: self.titleLabel!.font])
self.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: 0.0, bottom: 0.0, right: -titleSize.width)
}
}
}
a refined one
func alignTextUnderImage(spacing: CGFloat = 6.0) {
guard let image = imageView?.image, let label = titleLabel,
let string = label.text else { return }
titleEdgeInsets = UIEdgeInsets(top: spacing, left: -image.size.width, bottom: -image.size.height, right: 0.0)
let titleSize = string.size(withAttributes: [NSAttributedString.Key.font: label.font])
imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: 0.0, bottom: 0.0, right: -titleSize.width)
}
Setting Attribute Inspector in storyboard
Setup button size
Setup image's top
Setup title's top and left
Thank you #rbiard. Another workaround when you are developing a multilingual mobile app and when using UISemanticContentAttribute (right to left and left to right). This should work:
func alignTextBelow(spacing: CGFloat = 10.0) {
guard
let image = imageView?.image,
let label = titleLabel,
let string = label.text
else { return }
let titleSize = string.size(withAttributes: [NSAttributedString.Key.font: label.font])
//when the selected language is English
if L102Language.currentAppleLanguage() == "en" {
titleEdgeInsets = UIEdgeInsets(top: spacing, left: -image.size.width, bottom: -image.size.height, right: 0)
imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: 0.0, bottom: 0.0, right: -titleSize.width)
} else {
//When selecting a right to left language. For example, Arabic
titleEdgeInsets = UIEdgeInsets(top: spacing, left: 0, bottom: -image.size.height, right: -image.size.width)
imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: -titleSize.width, bottom: 0, right: 0)
}
}
You cannot change layout directly in UIButton, but you can try to use these properties on UIButton:
UIButton *button = ...
button.titleEdgeInsets = UIEdgeInsetsMake(....);
button.imageEdgeInsets = UIEdgeInsetsMake(....);
If it won't help I'd recommend to subclass from UIResponder and make your own component and do your own layout as you needed it.
I m very new to IOS development and AutoLayout .
I am facing issues to align the Image and Text inside UIbutton using Storyboard. I had tried to achieve it with TitleEdgeinset and ImageEdge insets accordingly to place the Title ( text ) vertically centered below the Image. But the issue is I have 3 similar buttons which are Vertically stacked ( StackView) and the Text is dynamically set since we have localized strings ( includes Arabic rtl ) .
The image and text moves according to the text length. Is there any ways that I can achieve to make all the buttons with image and text vertically alligned.Also, different screen resolutions are not currently working if using edge insets. Appreciate your help . Thanks in advance.
Few days ago, I solved similar problem,try this
private func adjustImageAndTitleOffsetsForButton (button: UIButton) {
let spacing: CGFloat = 6.0
let imageSize = button.imageView!.frame.size
button.titleEdgeInsets = UIEdgeInsetsMake(0, -imageSize.width, -(imageSize.height + spacing), 0)
let titleSize = button.titleLabel!.frame.size
button.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + spacing), 0, 0, -titleSize.width)
}
call this method for each button, like
self.adjustImageAndTitleOffsetsForButton(yourButton)
Combining Ajay's and Matej's answer:
import Foundation
import UIKit
class VerticalButton: UIButton {
override func awakeFromNib() {
super.awakeFromNib()
self.contentHorizontalAlignment = .left
}
override func layoutSubviews() {
super.layoutSubviews()
centerButtonImageAndTitle()
}
private func centerButtonImageAndTitle() {
let titleSize = self.titleLabel?.frame.size ?? .zero
let imageSize = self.imageView?.frame.size ?? .zero
let spacing: CGFloat = 6.0
self.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing),left: 0, bottom: 0, right: -titleSize.width)
self.titleEdgeInsets = UIEdgeInsets(top: 0, left: -imageSize.width, bottom: -(imageSize.height + spacing), right: 0)
}
}
I've modified Ajay's answer because my images weren't centered:
func centerButtonImageAndTitle(button: UIButton) {
let spacing: CGFloat = 5
let titleSize = button.titleLabel!.frame.size
let imageSize = button.imageView!.frame.size
button.titleEdgeInsets = UIEdgeInsets(top: 0, left: -imageSize.width, bottom: -(imageSize.height + spacing), right: 0)
button.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: -imageSize.width/2, bottom: 0, right: -titleSize.width)
}
This is a solution that worked for me. Just set the button class to HorizontallyCenteredButton in storyboard and set the title and image top and bottom insets according to your needs (to place the image higher than title) and the button will adjust horizontal insets automatically so that the image is centered above title.
class HorizontallyCenteredButton: LocalizedButton {
override func awakeFromNib() {
super.awakeFromNib()
self.contentHorizontalAlignment = .left
}
override func layoutSubviews() {
super.layoutSubviews()
self.centerButtonImageAndTitle()
}
func centerButtonImageAndTitle() {
let size = self.bounds.size
let titleSize = self.titleLabel!.frame.size
let imageSize = self.imageView!.frame.size
self.imageEdgeInsets = UIEdgeInsets(top: self.imageEdgeInsets.top, left: size.width/2 - imageSize.width/2, bottom: self.imageEdgeInsets.bottom, right: 0)
self.titleEdgeInsets = UIEdgeInsets(top: self.titleEdgeInsets.top, left: -imageSize.width + size.width/2 - titleSize.width/2, bottom: self.titleEdgeInsets.bottom, right: 0)
}
}
To align all the buttons vertically, first select the buttons, then click the button on the bottom-right of the storyboard titled "Align", and finally select "Vertical Centers" in the menu that appears. That should do the trick.
I created a view, then put a VStack with image and text, as well as button.
Make sure the VStack constraints are 0 on all 4 sides so it covers the button :)
this is an easy one, so apologies if you have already tried it!
you don't need to set anything for insets, just make sure that the 3 buttons are aligned with horizontal centres ...
select the controls you want to align, and click on the button highlighted below (bottom right on the xCode screen) and select the Vertical Centres option to align the three with each other, or select Horizontally in Container to put them in the middle of your view.
I don't want to use a subview if I can avoid it. I want a UIButton with a background image, text, and an image in it. Right now, when I do that, the image is on the left side of the text. The background image, text, and image all have different highlight states.
Simplest solution:
iOS 10 & up, Swift:
button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
Before iOS 10, Swift/Obj-C:
button.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.titleLabel.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.imageView.transform = CGAffineTransformMakeScale(-1.0, 1.0);
iOS 9 & up, Swift: (Recommended)
button.semanticContentAttribute = .forceRightToLeft
Despite some of the suggested answers being very creative and extremely clever, the simplest solution is as follows:
button.semanticContentAttribute = UIApplication.shared
.userInterfaceLayoutDirection == .rightToLeft ? .forceLeftToRight : .forceRightToLeft
As simple as that. As a bonus, the image will be at the left side in right-to-left locales.
EDIT: as the question has been asked a few times, this is iOS 9 +.
UPDATED FOR XCODE 9 (Via Interface Builder)
There's an easier way from the Interface Builder.
Select the UIButton and select this option in the View Utilities > Semantic:
That's it! Nice and simple!
OPTIONAL - 2nd step:
If you want to adjust the spacing between the image and the title you can change the Image Inset here:
Subclassing UIButton is completely unnecessary. Instead you can simply set a high left inset value for the image insets, and a small right inset for the title. Something like this:
button.imageEdgeInsets = UIEdgeInsetsMake(0., button.frame.size.width - (image.size.width + 15.), 0., 0.);
button.titleEdgeInsets = UIEdgeInsetsMake(0., 0., 0., image.size.width);
I'm giving Inspire48 the credit for this one. Based on his suggestion and looking at that other question I came up with this. Subclass UIButton and override these methods.
#implementation UIButtonSubclass
- (CGRect)imageRectForContentRect:(CGRect)contentRect
{
CGRect frame = [super imageRectForContentRect:contentRect];
frame.origin.x = CGRectGetMaxX(contentRect) - CGRectGetWidth(frame) - self.imageEdgeInsets.right + self.imageEdgeInsets.left;
return frame;
}
- (CGRect)titleRectForContentRect:(CGRect)contentRect
{
CGRect frame = [super titleRectForContentRect:contentRect];
frame.origin.x = CGRectGetMinX(frame) - CGRectGetWidth([self imageRectForContentRect:contentRect]);
return frame;
}
#end
Just update the insets when the title is changed. You need to compensate for the inset with an equal and opposite inset on the other side.
[thebutton setTitle:title forState:UIControlStateNormal];
thebutton.titleEdgeInsets = UIEdgeInsetsMake(0, -thebutton.imageView.frame.size.width, 0, thebutton.imageView.frame.size.width);
thebutton.imageEdgeInsets = UIEdgeInsetsMake(0, thebutton.titleLabel.frame.size.width, 0, -thebutton.titleLabel.frame.size.width);
All of these answers, as of January 2016, are unnecessary. In Interface Builder, set the View Semantic to Force Right-to-Left, or if you prefer programmatic way, semanticContentAttribute = .forceRightToLeft That will cause the image to appear on the right of your text.
In interface builder you can configure options Edge Insets for UIButton, separately each of three parts: content, image, title
Xcode 8:
I decided not to use the standard button image view because the proposed solutions to move it around felt hacky. This got me the desired aesthetic, and it is intuitive to reposition the button by changing the constraints:
extension UIButton {
func addRightIcon(image: UIImage) {
let imageView = UIImageView(image: image)
imageView.translatesAutoresizingMaskIntoConstraints = false
addSubview(imageView)
let length = CGFloat(15)
titleEdgeInsets.right += length
NSLayoutConstraint.activate([
imageView.leadingAnchor.constraint(equalTo: self.titleLabel!.trailingAnchor, constant: 10),
imageView.centerYAnchor.constraint(equalTo: self.titleLabel!.centerYAnchor, constant: 0),
imageView.widthAnchor.constraint(equalToConstant: length),
imageView.heightAnchor.constraint(equalToConstant: length)
])
}
}
Update: Swift 3
class ButtonIconRight: UIButton {
override func imageRect(forContentRect contentRect:CGRect) -> CGRect {
var imageFrame = super.imageRect(forContentRect: contentRect)
imageFrame.origin.x = super.titleRect(forContentRect: contentRect).maxX - imageFrame.width
return imageFrame
}
override func titleRect(forContentRect contentRect:CGRect) -> CGRect {
var titleFrame = super.titleRect(forContentRect: contentRect)
if (self.currentImage != nil) {
titleFrame.origin.x = super.imageRect(forContentRect: contentRect).minX
}
return titleFrame
}
}
Original answer for Swift 2:
A solution that handles all horizontal alignments, with a Swift implementation example. Just translate to Objective-C if needed.
class ButtonIconRight: UIButton {
override func imageRectForContentRect(contentRect:CGRect) -> CGRect {
var imageFrame = super.imageRectForContentRect(contentRect)
imageFrame.origin.x = CGRectGetMaxX(super.titleRectForContentRect(contentRect)) - CGRectGetWidth(imageFrame)
return imageFrame
}
override func titleRectForContentRect(contentRect:CGRect) -> CGRect {
var titleFrame = super.titleRectForContentRect(contentRect)
if (self.currentImage != nil) {
titleFrame.origin.x = CGRectGetMinX(super.imageRectForContentRect(contentRect))
}
return titleFrame
}
}
Also worth noting that it handles quite well image & title insets.
Inspired from jasongregori answer ;)
If this need to be done in UIBarButtonItem, additional wrapping in view should be used
This will work
let view = UIView()
let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
view.addSubview(button)
view.frame = button.bounds
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: view)
This won't work
let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)
Do Yourself. Xcode10, swift4,
For programmatically UI design
lazy var buttonFilter : ButtonRightImageLeftTitle = {
var button = ButtonRightImageLeftTitle()
button.setTitle("Playfir", for: UIControl.State.normal)
button.setImage(UIImage(named: "filter"), for: UIControl.State.normal)
button.backgroundColor = UIColor.red
button.contentHorizontalAlignment = .left
button.titleLabel?.font = UIFont.systemFont(ofSize: 16)
return button
}()
Edge inset values are applied to a rectangle to shrink or expand the
area represented by that rectangle. Typically, edge insets are used
during view layout to modify the view’s frame. Positive values cause
the frame to be inset (or shrunk) by the specified amount. Negative
values cause the frame to be outset (or expanded) by the specified
amount.
class ButtonRightImageLeftTitle: UIButton {
override func layoutSubviews() {
super.layoutSubviews()
guard imageView != nil else { return }
imageEdgeInsets = UIEdgeInsets(top: 5, left: (bounds.width - 35), bottom: 5, right: 5)
titleEdgeInsets = UIEdgeInsets(top: 0, left: -((imageView?.bounds.width)! + 10), bottom: 0, right: 0 )
}
}
for StoryBoard UI design
iOS 15 brought an update where you can now handle image placements in buttons in a simpler non messier way, ie. without insets.
In XIB/Storyboards:
Simply set the button 'placement' property to leading/training/top/bottom after adding an image property to button. Since it's leading/training, there is an added advantage of it supporting RTL
**In code (Programmatically): **
Use Button Configuration property programmatically
This is not a backward compatible feature, and will work only in iOS15+ as was demonstrated in WWDC '21 - https://developer.apple.com/videos/play/wwdc2021/10064/?time=236
Developer documentation: https://developer.apple.com/documentation/uikit/uibutton/configuration?changes=_4
Here is solution for UIButton with center aligned content.
This code make image right aligned and allows to use imageEdgeInsets and titleEdgeInsets for precious positioning.
Subclass UIButton with your custom class and add:
- (CGRect)imageRectForContentRect:(CGRect)contentRect {
CGRect frame = [super imageRectForContentRect:contentRect];
CGFloat imageWidth = frame.size.width;
CGRect titleRect = CGRectZero;
titleRect.size = [[self titleForState:self.state] sizeWithAttributes:#{NSFontAttributeName: self.titleLabel.font}];
titleRect.origin.x = (self.frame.size.width - (titleRect.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
frame.origin.x = titleRect.origin.x + titleRect.size.width - self.imageEdgeInsets.right + self.imageEdgeInsets.left;
return frame;
}
- (CGRect)titleRectForContentRect:(CGRect)contentRect {
CGFloat imageWidth = [self imageForState:self.state].size.width;
CGRect frame = [super titleRectForContentRect:contentRect];
frame.origin.x = (self.frame.size.width - (frame.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
return frame;
}
Extension Way
Using extension to set image on the right side with custom offset
extension UIButton {
func addRightImage(image: UIImage, offset: CGFloat) {
self.setImage(image, for: .normal)
self.imageView?.translatesAutoresizingMaskIntoConstraints = false
self.imageView?.centerYAnchor.constraint(equalTo: self.centerYAnchor, constant: 0.0).isActive = true
self.imageView?.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -offset).isActive = true
}
}
Being that the transform solution doesn't work in iOS 11 I decided to write a new approach.
Adjusting the buttons semanticContentAttribute gives us the image nicely to the right without having to relayout if the text changes. Because of this it's the ideal solution. However I still need RTL support. The fact that an app can not change it's layout direction in the same session resolves this issue easily.
With that said, it's pretty straight forward.
extension UIButton {
func alignImageRight() {
if UIApplication.shared.userInterfaceLayoutDirection == .leftToRight {
semanticContentAttribute = .forceRightToLeft
}
else {
semanticContentAttribute = .forceLeftToRight
}
}
}
Swift -Extend the UiButton and put these lines
if let imageWidth = self.imageView?.frame.width {
self.titleEdgeInsets = UIEdgeInsetsMake(0, -imageWidth, 0, imageWidth);
}
if let titleWidth = self.titleLabel?.frame.width {
let spacing = titleWidth + 20
self.imageEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, -spacing);
}
Building on Piotr Tomasik's elegant solution: if you want to have a bit of spacing between the button label and image as well, then include that in your edge insets as follows (copying my code here that works perfectly for me):
CGFloat spacing = 3;
CGFloat insetAmount = 0.5 * spacing;
// First set overall size of the button:
button.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount);
[button sizeToFit];
// Then adjust title and image insets so image is flipped to the right and there is spacing between title and image:
button.titleEdgeInsets = UIEdgeInsetsMake(0, -button.imageView.frame.size.width - insetAmount, 0, button.imageView.frame.size.width + insetAmount);
button.imageEdgeInsets = UIEdgeInsetsMake(0, button.titleLabel.frame.size.width + insetAmount, 0, -button.titleLabel.frame.size.width - insetAmount);
Thanks Piotr for your solution!
Erik
Took #Piotr's answer and made it into a Swift extension. Make sure to set the image and title before calling this, so that the button sizes properly.
extension UIButton {
/// Makes the ``imageView`` appear just to the right of the ``titleLabel``.
func alignImageRight() {
if let titleLabel = self.titleLabel, imageView = self.imageView {
// Force the label and image to resize.
titleLabel.sizeToFit()
imageView.sizeToFit()
imageView.contentMode = .ScaleAspectFit
// Set the insets so that the title appears to the left and the image appears to the right.
// Make the image appear slightly off the top/bottom edges of the button.
self.titleEdgeInsets = UIEdgeInsets(top: 0, left: -1 * imageView.frame.size.width,
bottom: 0, right: imageView.frame.size.width)
self.imageEdgeInsets = UIEdgeInsets(top: 4, left: titleLabel.frame.size.width,
bottom: 4, right: -1 * titleLabel.frame.size.width)
}
}
}
With Xcode 13.3 I solved in the following few steps and as well adding padding to the image.
After creating the button then do this as listed below:
First define the image:
let symbol = UIImage(named: "put name of your symbol here")
Then in viewDidLoad where you created the button, initialise the above defined image in 1, to add the image to the button & set the properties:
button.setImage(symbol, for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.configuration?.imagePadding = 2
And don't forget to add your button to the view.
Subclassing and over-riding layoutSubviews is probably your best way to go.
Referenced from: iPhone UIButton - image position
A swift option that does what you want without playing with any insets:
class RightImageButton: UIButton {
override func layoutSubviews() {
super.layoutSubviews()
if let textSize = titleLabel?.intrinsicContentSize(),
imageSize = imageView?.intrinsicContentSize() {
let wholeWidth = textSize.width + K.textImageGap + imageSize.width
titleLabel?.frame = CGRect(
x: round(bounds.width/2 - wholeWidth/2),
y: 0,
width: ceil(textSize.width),
height: bounds.height)
imageView?.frame = CGRect(
x: round(bounds.width/2 + wholeWidth/2 - imageSize.width),
y: RoundRetina(bounds.height/2 - imageSize.height/2),
width: imageSize.width,
height: imageSize.height)
}
}
struct K {
static let textImageGap: CGFloat = 5
}
}
Solutions mentioned here stopped working, once I enabled Auto Layout. I had to come up with my own:
Subclass UIButton and override layoutSubviews method:
//
// MIThemeButtonImageAtRight.m
// Created by Lukasz Margielewski on 7/9/13.
//
#import "MIThemeButtonImageAtRight.h"
static CGRect CGRectByApplyingUIEdgeInsets(CGRect frame, UIEdgeInsets insets);
#implementation MIThemeButtonImageAtRight
- (void)layoutSubviews
{
[super layoutSubviews];
CGRect contentFrame = CGRectByApplyingUIEdgeInsets(self.bounds, self.contentEdgeInsets);
CGRect frameIcon = self.imageView.frame;
CGRect frameText = self.titleLabel.frame;
frameText.origin.x = CGRectGetMinX(contentFrame) + self.titleEdgeInsets.left;
frameIcon.origin.x = CGRectGetMaxX(contentFrame) - CGRectGetWidth(frameIcon);
self.imageView.frame = frameIcon;
self.titleLabel.frame = frameText;
}
#end
static CGRect CGRectByApplyingUIEdgeInsets(CGRect frame, UIEdgeInsets insets){
CGRect f = frame;
f.origin.x += insets.left;
f.size.width -= (insets.left + insets.right);
f.origin.y += (insets.top);
f.size.height -= (insets.top + insets.bottom);
return f;
}

For anyone trying to mirror the Back button style with the chevron like this:
import UIKit
class NextBarButton: UIBarButtonItem {
convenience init(target: Any, selector: Selector) {
// Create UIButton
let button = UIButton(frame: .zero)
// Set Title
button.setTitle("Next", for: .normal)
button.setTitleColor(.systemBlue, for: .normal)
button.titleLabel?.font = UIFont.systemFont(ofSize: 17)
// Configure Symbol
let config = UIImage.SymbolConfiguration(pointSize: 19.0, weight: .semibold, scale: .large)
let image = UIImage(systemName: "chevron.right", withConfiguration: config)
button.setImage(image, for: .normal)
// Add Target
button.addTarget(target, action: selector, for: .touchUpInside)
// Put the Image on the right hand side of the button
// Credit to liau-jian-jie for this part
button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
// Customise spacing to match system Back button
button.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: -18.0, bottom: 0.0, right: 0.0)
button.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -12.0, bottom: 0.0, right: 0.0)
self.init(customView: button)
}
}
Implementation:
override func viewDidLoad() {
super.viewDidLoad()
let nextButton = NextBarButton(target: self, selector: #selector(nextTapped))
navigationItem.rightBarButtonItem = nextButton
}
#objc func nextTapped() {
// your code
}
Swift 3:
open override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
var frame = super.imageRect(forContentRect: contentRect)
let imageWidth = frame.size.width
var titleRect = CGRect.zero
titleRect.size = self.title(for: self.state)!.size(attributes: [NSFontAttributeName: self.titleLabel!.font])
titleRect.origin.x = (self.frame.size.width - (titleRect.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
frame.origin.x = titleRect.origin.x + titleRect.size.width - self.imageEdgeInsets.right + self.imageEdgeInsets.left;
return frame
}
open override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
var frame = super.titleRect(forContentRect: contentRect)
if let imageWidth = self.image(for: self.state)?.size.width {
frame.origin.x = (self.frame.size.width - (frame.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
}
return frame
}
How about Constraints? Unlike semanticContentAttribute, they don't change semantics. Something like this perhaps:
button.rightAnchorconstraint(equalTo: button.rightAnchor).isActive = true
or in Objective-C:
[button.imageView.rightAnchor constraintEqualToAnchor:button.rightAnchor].isActive = YES;
Caveats: Untested, iOS 9+
After trying multiple solutions from around the internet, I was not achieving the exact requirement. So I ended up writing custom utility code. Posting to help someone in future.
Tested on swift 4.2
// This function should be called in/after viewDidAppear to let view render
func addArrowImageToButton(button: UIButton, arrowImage:UIImage = #imageLiteral(resourceName: "my_image_name") ) {
let btnSize:CGFloat = 32
let imageView = UIImageView(image: arrowImage)
let btnFrame = button.frame
imageView.frame = CGRect(x: btnFrame.width-btnSize-8, y: btnFrame.height/2 - btnSize/2, width: btnSize, height: btnSize)
button.addSubview(imageView)
//Imageview on Top of View
button.bringSubviewToFront(imageView)
}
for this issue you can create UIView inside "label with UIImage view" and set UIView class as a UIControl and create IBAction as tuch up in side
Swift 4 & 5
Change the direction of UIButton image (RTL and LTR)
extension UIButton {
func changeDirection(){
isArabic ? (self.contentHorizontalAlignment = .right) : (self.contentHorizontalAlignment = .left)
// left-right margin
self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
self.titleEdgeInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
}
}
