I am trying to add a "calendar day" image to surround some text on a clickable UI button like so:
let button = UIButton()
let X_Offset : CGFloat = (95 * CGFloat(buttonCount) ) + 10
let scrollHeight = scrollView.bounds.height
button.frame = CGRect(x: X_Offset, y: scrollHeight/6, width: 70, height: 60)
let buttonText = event.startTime.toShortDayOfWeekString() + "\n" + event.startTime.toShortDayOfMonthString()
button.titleLabel!.lineBreakMode = .byWordWrapping
button.titleLabel!.textAlignment = .center
button.setTitle(buttonText, for: .normal)
button.tag = i
button.backgroundColor = CompanyColor.Red.color
let image = UIImage(named: "calendarDay")
button.setBackgroundImage(image, for: .normal)
button.titleLabel?.font = UIFont(name: "Roboto", size: 14)
button.layer.cornerRadius = 8
button.clipsToBounds = true
But the image is encroaching on the text a bit too much:
How can I get the background image to scale up slightly and leave enough gap for the text?
I think what you what you are looking for is setting imageEdgeInsets for UIButton. Setting of these properties lets you move image around besides its default position. You have to play around to get your desired result.
There are two ways you can do this. One is using Interface Builder and other one is programmatically. Interface builder is easiest way to go I guess. Below image shows how can you set those properties for UIButton.
or try using programmatically like this
button.imageEdgeInsets = UIEdgeInsets(top: -10, left: 32, bottom: -10, right: 50)
You can move title like this
button.titleEdgeInsets = UIEdgeInsets(top: 0, left:0, bottom: 0, right: 20)
Note: Setting UIEdgeInsets like this might have different result if you have dynamic size button e.g. for different screen size. Always make sure that it looks as expected for all screen sizes.

Swift 4.2 implemented views programmatically only
I have created a stack view and put four buttons in it but they are just simple buttons without any gray background.
I want to achieve the exact four buttons in my stackview equally centered as like as -
button.contentEdgeInset //Not working
This is what I tried -
let feedbackButton:UIButton = {
let origImage = UIImage(named: "feedback")
let tintedImage = origImage?.withRenderingMode(.alwaysTemplate)
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.translatesAutoresizingMaskIntoConstraints = false
button.setBackgroundImage(tintedImage, for: UIControl.State.normal)
button.tintColor = .systemPinkColor
button.layer.cornerRadius = 7
button.backgroundColor = UIColor.lightGray.withAlphaComponent(0.5)
button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 40, bottom: 0, right: 40)
// button.imageEdgeInsets = UIEdgeInsets(top: 0, left: 50, bottom: 0, right: 50)
// button.titleEdgeInsets = UIEdgeInsets(top: 0, left: 50, bottom: 0, right: 50)
button.clipsToBounds = true
button.addTarget(self, action: #selector(feedbackFaculty), for: .touchUpInside)
return button
}()
Output -
The button's image gets stretched along with insets. button.imageInsets and button.titleInsets not working.
Help me out. Thanks!
The background image doesn't follow the content insets. So this line:
button.setBackgroundImage(tintedImage, for: UIControl.State.normal)
needs to be changed to:
button.setImage(tintedImage, for: .normal)
Also, here's a couple things to note (per Apple's UIButton documentation):
Supply a title string or image; size the button appropriately for your content.
Which implies that you cannot set an image and title at the same time, this might be why you're noticing titleInset and imageInset not playing nicely.
However, if you just set appropriate constraints for the buttons and set insets for the title OR the image you should be able to get the look you want. Also make sure your stack view is configured to use equal spacing for it's distribution.
The imageInset for each button in the image below is (20, 20, 20, 20).
How can i display the UIButton titleLabel text to bottom of its frame. Currently i am using the UIEdge top margin and setting the negative UIButton image width, result is not as expected. i also want to place the image center to its frame.
`
let leftButton: UIButton = {
let button = UIButton()
button.layer.borderWidth = 2
button.layer.borderColor = UIColor.ublGray1().cgColor
button.setImage(UIImage.init(named: leftButtonImage)?.withRenderingMode(.alwaysTemplate), for: .normal)
button.tintColor = UIColor.cerulean()
button.layer.masksToBounds = false
button.layer.cornerRadius = 37
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle(leftButtonTitle, for: .normal)
button.titleEdgeInsets = UIEdgeInsets(top: 110, left: -26, bottom: 0, right: 0)[![enter image description here][1]][1]
button.imageEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)
button.setTitleColor(UIColor.charcoalGrey(), for: .normal)
button.titleLabel?.font = UIFont.aspiraMedium(size: 16)
return button
}()
`
You can try something like this.
How about setting "Title Insets" - bottom - to a negative number? It works.
But if you want it to stick to the bottom of the frame, it won't work, so... how about this:
bt.titleEdgeInsets.top = (bt.imageView?.safeAreaInsets.bottom)!
or bt.titleEdgeInsets.top = (bt.imageView?.alignmentRectInsets.bottom)!
I have a UIScrollView inside a UIViewController and I expect it to be scrolled horizontally. I programmatically add button to the ScrollView by a loop. After the loop, I set the myScrollView.contentSize.width to be buttonWidth * numberOfButtons. I also double check to make sure that contentSize is bigger than the scrollview's frame (in this case the scrollview has width of 375).
let numberOfButton = 7
for index in 0..<numberOfButton {
let button = UIButton()
let frame = CGRect(x: 80 + (index * 80), y: 6, width: 60, height: 32)
button.setTitle("Button" + String(index), forState: .Normal)
button.frame = frame
button.titleLabel?.font = UIFont(name: "Museo Sans", size: 16)
button.setTitleColor(UIColor.blueColor(), forState: .Normal)
myScrollView.addSubview(button)
}
myScrollView.contentSize = CGSize(width: 100*numberOfButtons, height: 42)
When I run the code, it only appears to the Button3 (there are 7 buttons) and I cannot scroll it to the end. However, when I set myScrollView.bounces = true I can drag the scrollview around and see other buttons but it will bounce back to the original state. Any help would be much appreciated.
I think your problem is setting the X value on the first button. I have just tried this code and it works fine
let numberOfButtons = 7
for index in 0..<numberOfButtons {
let button = UIButton()
let frame = CGRect(x: 8 + (index * 96), y: 6, width: 80, height: 32)
button.setTitle("Button \(index)", for: .normal)
button.frame = frame
button.titleLabel?.font = UIFont(name: "Museo Sans", size: 16)
button.setTitleColor(UIColor.blue, for: .normal)
myScrollView.addSubview(button)
}
myScrollView.contentSize = CGSize(width: 100*numberOfButton, height: 42)
Change this
tagBar.contentSize = CGSize(width: 100*7, height: 42)
to
myScrollView.contentSize = CGSize(width: 100*7, height: 42)
The answer that Rajeshkumar R gave you, or better use constraints. You can set a constraint between the left of myScrollView and the left your first button (a "leading space" constraint), then a leading space constraint between each button and the previous one, and when you finish looping, a trailing space from your last button to the myScrollView.
This way you don't have to calculate the contentSize yourself. It's also more extensible (for example, if you had buttons of different sizes, you would have to know each width, sum them all, then sum the margins between elements and between the first and the last one with the scrollView…).
I am trying to set a clickable "textonly"-button but right now I'm having problem fixing the height for my button. Before all this I tried having it as an label, but then the touchhandling gets complicated so I decided to just do a button with no frame etc..
So now I need to set the buttonheight to the Text thats inside, any ideas?
Heres a code snippet:
//...
button.setTitle("Log in", for: .normal)
button.setTitleColor(.white, for: .normal)
button.layer.borderWidth = 0
button.frame = CGRect
button.addTarget(self, action: #selector(LoginFunction), for: .touchUpInside)
//...
If you want multiple lines of text in your UIButton you should set yourButton.titleLabel?.numberOfLines = 0 and yourButton.titleLabel?.lineBreakMode = .byWordWrapping. You will get multiline button, which height you can configure as you want.
Also you calculate frame of your text you should use
let context = NSStringDrawingContext()
let frame = yourText.boundingRectWithSize(
CGSize(width: yourButtonWidth, height: 9999),
options: NSStringDrawingOptions.UsesLineFragmentOrigin,
attributes: dictionaryOfYourTextAttributes, context: context)
You should still have a frame for the button to be displayed in the UI. It define yours button position and size (including height). Here is an example for button with position (0,0) and size (100,100):
button.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
Maybe what you mean by "frame" is "border". You can achieve borderless button by setting borderWidth to 0, which you already did in your code.
button.layer.borderWidth = 0
If you want to set size for the text you can do:
button.titleLabel?.font = UIFont.systemFont(ofSize: 17)
I have this UIButton and an image to fit in.
I don't want that the image take all the space inside the button but just a little part of it right in the center, but if I resize the button it will resize the image too.
How can I do that, is there an option to set whatever dimension I want independently from the size of the UIButton?
Thanks!
This can be done through code in the following way:
let imageSize:CGSize = CGSize(width: 20, height: 20)
let button:UIButton = UIButton(type: UIButton.ButtonType.custom)
button.frame = CGRect(x: 200, y: 200, width: 60, height: 60)
button.backgroundColor = UIColor.yellow
button.setImage(UIImage(named: "chat.png"), for: UIControl.State.normal)
// The below line will give you what you want
button.imageEdgeInsets = UIEdgeInsets(
top: (button.frame.size.height - imageSize.height) / 2,
left: (button.frame.size.width - imageSize.width) / 2,
bottom: (button.frame.size.height - imageSize.height) / 2,
right: (button.frame.size.width - imageSize.width) / 2)
self.view.addSubview(button)
This way, you can achieve what you wanted.
I couldn't get the button's imageView to resize until I used contentHorizontalAlignment and contentVerticalAlignment both set to .fill. Then using imageEdgeInsets I repositioned the image.
let button = UIButton()
let image = UIImage(systemName: "bag.badge.plus")
button.setImage(image, for: .normal)
button.contentHorizontalAlignment = .fill
button.contentVerticalAlignment = .fill
button.imageEdgeInsets = UIEdgeInsets(top: 6, left: 6, bottom: 10, right: 10)
Result:
You can experiment with image view insets. Every UIButton has a property imageView.
In Swift 3 you can do this like so:
//let button = UIButton()
button.imageView?.backgroundColor = UIColor.red
button.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10)
red background is just so you know what is changing
I would do it this way:
A UIButton is just a UIView. You can simply add a UIImageView with a set image and call addSubview on the UIButton.
Taking into account what KVISH said before i have implemented this and it worked as expected. I posted this because Houman asked for an example.
//grab the image using the name of the pic
var image = UIImage(named: "picture")
//set the size for the image
image = image?.resize(toWidth: 18)
image = image?.resize(toHeight: 18)
//set the image to the button
buttonName.setImage(image, for: UIControlState.normal)
//adjust the position
buttonName.imageEdgeInsets = UIEdgeInsetsMake(8,16,9,0)
As of iOS 13, when using SF Symbols, I prefer this:
let button = UIButton()
let font = UIFont.systemFont(ofSize: 30) // <- make it larger, smaller, whatever you want.
let config = UIImage.SymbolConfiguration(font: font)
let image = UIImage(systemName: "bag.badge.plus", withConfiguration: config)
button.setImage(image, for: .normal)
These can be achieved by adding imageEdgeInsets to a UIButton.
In swift4.2
button.imageEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
