Right margin of custom clear button in iOS - ios

I create a custom clear button on my text field with a background image set.
I position it on the right view but it always positions with a default margin. What I want is to have a right margin, for example, of 8.
extension UITextField {
func clearButtonWithImage(_ image: UIImage) {
let clearButton = UIButton()
clearButton.setBackgroundImage(image, for: .normal)
clearButton.alpha = 0.25
clearButton.frame = CGRect(x: 0, y: 0, width: 20, height: 20)
clearButton.contentMode = .scaleAspectFit
clearButton.addTarget(self, action: #selector(self.clear(sender:)), for: .touchUpInside)
self.rightViewMode = .always
self.clearButtonMode = .never
self.rightView = clearButton
}
#objc func clear(sender: AnyObject) {
self.text = ""
}
}
I use a custom textfield class for changing the style of my textfield on selecting.
My custom Textfield Class:
class customSearchTextField: customTextField {
override var isSelected: Bool {
didSet {
setSelected(isSelected)
}
}
private func setSelected(_ selected: Bool) {
//UIView.animate(withDuration: 0.15, animations: {
self.transform = selected ? CGAffineTransform(scaleX: 1.05, y: 1.05) : CGAffineTransform.identity
self.cornerRadius = selected ? 2.0 : 0.0
if selected {
self.clearButtonWithImage(UIImage())
} else {
self.clearButtonWithImage(#imageLiteral(resourceName: "icClear"))
}
self.layer.shadowColor = UIColor .customDark.cgColor
self.layer.shadowOpacity = selected ? 0.19 : 0.0
//})
}
}
Tried positioning the image frame but it always stays the same.

You should take a look at rightViewRect(forBounds:) method. Create a subclass of UITextField and custom position and size of clear button inside this method.
For example
class customSearchTextField: customTextField {
override var isSelected: Bool {
didSet {
setSelected(isSelected)
}
}
private func setSelected(_ selected: Bool) {
//UIView.animate(withDuration: 0.15, animations: {
self.transform = selected ? CGAffineTransform(scaleX: 1.05, y: 1.05) : CGAffineTransform.identity
self.cornerRadius = selected ? 2.0 : 0.0
if selected {
self.clearButtonWithImage(UIImage())
} else {
self.clearButtonWithImage(#imageLiteral(resourceName: "icClear"))
}
self.layer.shadowColor = UIColor .customDark.cgColor
self.layer.shadowOpacity = selected ? 0.19 : 0.0
//})
}
override func rightViewRect(forBounds bounds: CGRect) -> CGRect {
var rect = super.rightViewRect(forBounds: bounds)
rect.origin.x -= 30 // Assume your right margin is 30
return rect
}
}

How to Make an UIButton Shrink Into an UIActivityIndicator When Pressed?

I'm trying to create an UIButton that will shrink down to an Activity Indicator when tapped on. The UIButton I'm referring to is named Request Ride. I have most of the code already set, but for some reason the button won't shrink and the indicator won't show up? I'll attach pictures of the app and my code.
// My app
// My end result I'm needing
// Main Storyboard
// HomeVC
#IBAction func actionBtnWasPressed(_ sender: Any) {
actionBtn.animateButton(shouldLoad: true, withMessage: nil)
}
// RoundedShadowButton
class RoundedShadowButton: UIButton {
// Variables
var originalSize: CGRect?
func setupView() {
originalSize = self.frame
self.layer.cornerRadius = 5.0
self.layer.shadowRadius = 10.0
self.layer.shadowColor = UIColor.darkGray.cgColor
self.layer.shadowOpacity = 0.3
self.layer.shadowOffset = CGSize.zero
}
override func awakeFromNib() {
setupView()
}
func animateButton(shouldLoad: Bool, withMessage message: String?) {
let spinner = UIActivityIndicatorView()
spinner.style = .large
spinner.color = UIColor.darkGray
spinner.alpha = 0.0
spinner.hidesWhenStopped = true
spinner.tag = 21
if shouldLoad {
self.addSubview(spinner)
self.setTitle("", for: .normal)
UIView.animate(withDuration: 0.2, animations: {
self.layer.cornerRadius = self.frame.height / 2
self.frame = CGRect(x: self.frame.midX - (self.frame.height / 2), y: self.frame.origin.y, width: self.frame.height, height: self.frame.height)
}) { (finished) in
if finished == true {
spinner.startAnimating()
spinner.center = CGPoint(x: self.bounds.width / 2 + 1, y: self.bounds.width / 2 + 1)
UIView.animate(withDuration: 0.2) {
spinner.alpha = 1.0
}
}
}
self.isUserInteractionEnabled = false
} else {
self.isUserInteractionEnabled = true
for subview in self.subviews {
if subview.tag == 21 {
subview.removeFromSuperview()
}
}
UIView.animate(withDuration: 0.2) {
self.layer.cornerRadius = 5.0
self.frame = self.originalSize!
self.setTitle(message, for: .normal)
}
}
}
}
One obvious thing is that this line is totally wrong:
spinner.center = CGPoint(x: self.frame.width / 2 + 1, y: self.frame.width / 2 + 1)
You are placing the spinner incorrectly. If the activity view is a subview of the button, then it needs to be centered at the middle of the button’s bounds, not its frame.
I was able to get an effect somewhat like what you are describing:
So this ought to be possible if you get your values right.

IOS Step menu using swift

I would like to create the stepper menu in IOS using swift, But I'm facing some issues. Here are the issues.
1) Portrait and landscape stepper menu is not propper.
2) How to set default step position with the method below method, It's working when button clicked. But I want to set when menu loads the first time.
self.stepView.setSelectedPosition(index: 2)
3) If it reached the position last, I would like to change the color for complete path parentPathRect.
4) Progress animation CABasicAnimation is not like the progress bar, I want to show the animation.
5) It should not remove the selected position color when changing the orientation.
As per my organization rules should not use third-party frameworks.

CALayer border colour and width are not changing?

I have 5 textFields and my requirement is I have to set 0.2 border width initially, after that when tap on edit button I have to change border width from 0.2 to 0.8 and again tap on submit button I have to change border width from 0.8 to 0.2.
The thing is that border colour and width are not changing. Here below is my code:
class EditProductCell: UITableViewCell {
override func awakeFromNib() {
super.awakeFromNib()
//Create Border Line.
createBorderLine(0.2,UIColor.lightGray)
}
//Create Border Line on Text Field
func createBorderLine(_ width : CGFloat, _ color : UIColor)//_ width : CGFloat, _ color : UIColor)
{
setBottomBorder(textField: InvoiceDate, width: width,color : color)
setBottomBorder(textField: InvoiceNumber, width: width,color : color)
setBottomBorder(textField: modelNumber, width: width,color : color)
setBottomBorder(textField: productName, width: width,color : color)
setBottomBorder(textField: serialNumber, width: width,color : color)
self.layoutSubviews()
}
}
Here is another class:
class EditProductView: BaseViewController {
//TableView
#IBOutlet var tableView: UITableView!
//View Did Load
override func viewDidLoad() {
super.viewDidLoad()
//self.view.backgroundColor = hexStringToUIColor(hex: "#CCCCCC")
tableView.delegate = self
tableView.dataSource = self
//Button Submit
self.btnSubmit.isHidden = true
tableView.bounces = false
tableView.alwaysBounceVertical = false
hideKeyboardWhenTappedAround()
}
//Button Submit
#IBAction func btnSubmitAction(_ sender: Any) {
self.btnSubmit.isHidden = true
let index : NSIndexPath = NSIndexPath(row: 0, section: 0)
let tCell : EditProductCell = self.tableView.cellForRow(at: index as IndexPath) as! EditProductCell
//Change border line
tCell.createBorderLine(0.2, UIColor.lightGray)
tCell.btnEdit.isHidden = false
dismissKeyboard()
}
func btnEditAction()
{
btnSubmit.isHidden = false
let index : NSIndexPath = NSIndexPath(row: 0, section: 0)
let tCell : EditProductCell = self.tableView.cellForRow(at: index as IndexPath) as! EditProductCell
tCell.btnEdit.isHidden = true
//Create border line
tCell.createBorderLine(0.8, UIColor.black)
dismissKeyboard()
}
}
Here is set bottom border method in separate class:
//Set Bottom border line.
func setBottomBorder(textField: UITextField, width: CGFloat,color : UIColor) {
let border = CALayer()
border.name = "BottomBorder"
border.borderColor = color.cgColor
border.frame = CGRect(x: 0, y: textField.frame.size.height - width,
width: textField.frame.size.width, height: width)
border.borderWidth = width
textField.borderStyle = UITextBorderStyle.none
textField.layer.addSublayer(border)
textField.layer.masksToBounds = true
}
You can see in my code that button submit and button edit. I am changing border line colour and width. Colour and width are not.
I also tried something in but not able to get width change.
override func layoutSublayers(of layer: CALayer) {
if (layer == self.layer)
{
layer.borderWidth = 0.3
}
}
//MARK:- TextField Delegate
extension EditProductCell : UITextFieldDelegate
{
func textFieldDidBeginEditing(_ textField: UITextField) {
if let sublayers = textField.layer.sublayers {
for layer: CALayer in sublayers {
if layer.name == "BottomBorder" {
layer.removeFromSuperlayer()
}
}
}
setBottomBorder(textField: textField, width: 0.8, color: hexStringToUIColor(hex: "#55ACEE"))
}
//TextField Did End Editing
func textFieldDidEndEditing(_ textField: UITextField) {
if let sublayers = textField.layer.sublayers {
for layer: CALayer in sublayers {
if layer.name == "BottomBorder" {
layer.removeFromSuperlayer()
}
}
}
setBottomBorder(textField: textField, width: 0.8,color : UIColor.black)
textField.resignFirstResponder()
}
//TextField Return Key
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
// Try to find next responder
if let nextField = textField.superview?.viewWithTag(textField.tag + 1) as? UITextField
{
nextField.becomeFirstResponder()
}
else
{
textField.resignFirstResponder()
}
return false
}
}
Swift 4
shape.strokeColor = UIColor.lightGray.cgColor
shape.lineWidth = 1.0
If you try with numbers greater than 1 your code works. I think the border width need to be greater than 1.

UIPanGestureRecognizer on subclass UIView

I've been trying to lean more about subclassing certain objects.
Now I've subclassed a UIView which has a PanGestureRecognizer for swiping left and right.
Can't seem to find the problem. It won't even move the UIView. I've tried looking the lifecycle of an UIView to set the isUserInteractionEnabled to true, but with no result. See the code below:
VC
import UIKit
class SwipeViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
addNewProfile()
}
private func addNewProfile() {
let swipeView = SwiperView(frame: CGRect(x: self.view.bounds.width / 2 - 150, y: self.view.bounds.height / 2 - 75, width: 300, height: 150))
swipeView.parentView = self.view
swipeView.delegate = self
swipeView.shadow = true
swipeView.isUserInteractionEnabled = true
swipeView.backgroundColor = UIColor.white
swipeView.alpha = 0.0
view.addSubview(swipeView)
UIView.animate(withDuration: 0.3, animations: {
swipeView.alpha = 1.0
}, completion: { (succeed) in
swipeView.isUserInteractionEnabled = true
})
}
}
//MARK: - ChosenSwipeResultDelegate
extension SwipeViewController: ChosenSwipeResultDelegate {
func pickedLeftSide() {
}
func pickedRightSide() {
}
}

protocol ChosenSwipeResultDelegate {
func pickedLeftSide()
func pickedRightSide()
}
#IBDesignable class SwiperView: UIView {
private var _shadow: Bool!
private var _parentView: UIView!
var delegate: ChosenSwipeResultDelegate?
var parentView: UIView {
set {
_parentView = newValue
}
get {
return _parentView
}
}
#IBInspectable var shadow: Bool {
get {
return layer.shadowOpacity > 0.0
}
set {
if newValue == true {
addShadow()
}
}
}
#IBInspectable var cornerRadius: CGFloat {
get {
return layer.cornerRadius
}
set {
layer.cornerRadius = newValue
if shadow == false {
layer.masksToBounds = true
}
}
}
override func setNeedsLayout() {
super.setNeedsLayout()
isUserInteractionEnabled = true
}
override func awakeFromNib() {
super.awakeFromNib()
isUserInteractionEnabled = true
let dragGesture = UIPanGestureRecognizer(target: self, action: #selector(SwiperView.dragging(gesture:)))
addGestureRecognizer(dragGesture)
}
func dragging(gesture: UIPanGestureRecognizer) {
let translation = gesture.translation(in: parentView)
let tinderView = gesture.view!
tinderView.center = CGPoint(x: parentView.bounds.width / 2 + translation.x, y: parentView.bounds.height / 2 + translation.y)
let xFromCenter = tinderView.center.x - parentView.bounds.width / 2
let scale = min(100 / abs(xFromCenter), 1)
var rotation = CGAffineTransform(rotationAngle: xFromCenter / 200)
let stretch = rotation.scaledBy(x: scale, y: scale)
tinderView.transform = stretch
if gesture.state == .ended {
if tinderView.center.x < 100 {
print("left")
UIView.animate(withDuration: 0.3, animations: {
tinderView.alpha = 0.0
}, completion: { (succeed) in
self.delegate?.pickedLeftSide()
})
} else if tinderView.center.x > parentView.bounds.width - 100 {
print("right")
UIView.animate(withDuration: 0.3, animations: {
tinderView.alpha = 0.0
}, completion: { (succeed) in
self.delegate?.pickedRightSide()
})
} else {
print("Not chosen")
rotation = CGAffineTransform(rotationAngle: 0)
let stretch = rotation.scaledBy(x: 1, y: 1)
tinderView.transform = stretch
tinderView.center = CGPoint(x: parentView.bounds.width / 2, y: parentView.bounds.height / 2)
}
}
}
private func addShadow(shadowColor: CGColor = UIColor.black.cgColor, shadowOffset: CGSize = CGSize(width: 1.0, height: 2.0), shadowOpacity: Float = 0.4, shadowRadius: CGFloat = 3.0) {

layer.shadowOffset = shadowOffset
layer.shadowOpacity = shadowOpacity
layer.shadowRadius = shadowRadius

}
add these code to your SwiperView see if it solves the problem
override init(frame: CGRect) {
super.init(frame: frame)
isUserInteractionEnabled = true
let dragGesture = UIPanGestureRecognizer(target: self, action: #selector(SwiperView.dragging(gesture:)))
addGestureRecognizer(dragGesture)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
isUserInteractionEnabled = true
let dragGesture = UIPanGestureRecognizer(target: self, action: #selector(SwiperView.dragging(gesture:)))
addGestureRecognizer(dragGesture)
}

UIView changing its position in swift

How do I make a UIView slide up with a touch of a button from its original position and them bring it back down with a touch of a button? Using Swift and Xcode 6.
I have currently tried this:
#IBOutlet weak var DynView: UIView!
#IBAction func btnUp(sender: AnyObject) {
}
You have to implement an animation changing the DynView position on click. Here's an example:
#IBAction func btnUp(sender: AnyObject) {
let xPosition = DynView.frame.origin.x
let yPosition = DynView.frame.origin.y - 20 // Slide Up - 20px
let width = DynView.frame.size.width
let height = DynView.frame.size.height
UIView.animateWithDuration(1.0, animations: {
dynView.frame = CGRect(x: xPosition, y: yPosition, width: width, height: height)
})
}
Hi create this extends if you want. For Swift
Create File Extends.Swift and add this code
/**
Extension UIView
by DaRk-_-D0G
*/
extension UIView {
/**
Set x Position
:param: x CGFloat
by DaRk-_-D0G
*/
func setX(#x:CGFloat) {
var frame:CGRect = self.frame
frame.origin.x = x
self.frame = frame
}
/**
Set y Position
:param: y CGFloat
by DaRk-_-D0G
*/
func setY(#y:CGFloat) {
var frame:CGRect = self.frame
frame.origin.y = y
self.frame = frame
}
/**
Set Width
:param: width CGFloat
by DaRk-_-D0G
*/
func setWidth(#width:CGFloat) {
var frame:CGRect = self.frame
frame.size.width = width
self.frame = frame
}
/**
Set Height
:param: height CGFloat
by DaRk-_-D0G
*/
func setHeight(#height:CGFloat) {
var frame:CGRect = self.frame
frame.size.height = height
self.frame = frame
}
}
For Use (inherits Of UIView)
inheritsOfUIView.setX(x: 100)
button.setX(x: 100)
view.setY(y: 100)
I kinda combined the two most voted answers into one and updated to Swift 3. So basically created an extension that animates a view moving to a different position:
extension UIView {
func slideX(x:CGFloat) {
let yPosition = self.frame.origin.y
let height = self.frame.height
let width = self.frame.width
UIView.animate(withDuration: 1.0, animations: {
self.frame = CGRect(x: x, y: yPosition, width: width, height: height)
})
}
}
// MARK: - Properties
var bottomViewHeight: CGFloat = 200
var isViewHide = false
private let bottomView: UIView = {
let view = UIView()
view.backgroundColor = .red
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
private let showHideButton: UIButton = {
let button = UIButton()
button.setTitle("Show / Hide", for: .normal)
button.setTitleColor(.black, for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
button.addTarget(self, action: #selector(showHideButtonTapped(_:)), for: .touchUpInside)
return button
}()
// MARK: - Lifecycle
override func loadView() {
super.loadView()
view.addSubview(bottomView)
NSLayoutConstraint.activate([
bottomView.heightAnchor.constraint(equalToConstant: bottomViewHeight),

bottomView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor),

])
view.addSubview(showHideButton)
NSLayoutConstraint.activate([

showHideButton.centerXAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerXAnchor),

])
}
override func viewDidLoad() {
super.viewDidLoad()
showHideView(isShow: isViewHide)
}
// MARK: - Selectors
#objc func showHideButtonTapped(_ sender: UIButton) {

private func showHideView(isShow: Bool) {
if isShow {
UIView.animate(withDuration: 0.4) {
self.bottomView.transform = CGAffineTransform(translationX: 0, y: self.bottomViewHeight)
}
} else {
UIView.animate(withDuration: 0.4) {
self.bottomView.transform = CGAffineTransform(translationX: 0, y: 0)
}
}
isViewHide = !isViewHide
