lblNavTitle?.textAlignment = .center
lblNavTitle?.lineBreakMode = .byTruncatingMiddle

I am trying to add a card view to the rows of the section, where for the first row I want the top left and top right shadow with corner radius and the last row of the section will have the bottom left and bottom right shadow with corner radius. So in the middles rows will have only left and right shadow without corner radius.
Try this it is working for me
yourRowView.layer.shadowOpacity = 0.8
yourRowView.layer.shadowOffset = CGSize(width: 0, height: 3)
yourRowView.layer.shadowRadius = 4.0
let shadowRect: CGRect = imageView.bounds.insetBy(dx: 0, dy: 4)
yourRowView.layer.shadowPath = UIBezierPath(rect: shadowRect).cgPath

I have a problem: my scroll view scrollable, when content is fully visible. What should i do, to enable scrolling, when some part of content is hidden?
This is the solution. I faced the same issue few months back.
public override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
ScrollView.contentSize = CGSize(width: self.view.frame.width, height: self.view.frame.height)
ScrollView.isScrollEnabled = true
ScrollView.showsVerticalScrollIndicator = false
}
Enjoy!

I have 2 UIButton as shown in below image. Here I need to customize exactly the same for both, mean texts, how could I do this.
Suggest how could I do this either in storyboard (using label/view ..) or programmatically. Guide me with some piece of code for NSAttributtedstring in case of label or button text as shown in image.
You can use this below func :
extension UILabel {
func setAttributes(price : String) {
let font:UIFont? = UIFont.boldSystemFont(ofSize: 22)
let fontSuper:UIFont? = UIFont.boldSystemFont(ofSize: 15)
let aDotRange = (price as NSString).range(of: ".")
let attString:NSMutableAttributedString = NSMutableAttributedString(string: price, attributes: [.font:font!])
attString.setAttributes([.font:fontSuper!,.baselineOffset:5], range: NSRange(location:0,length:1))
attString.setAttributes([.font:fontSuper!,.baselineOffset:5],
range: NSRange(location:aDotRange.location,length:4))
attString.setAttributes([.font:font!],
range: NSRange(location:1,length:aDotRange.location - 1 ))
attString.setAttributes([.font:fontSuper!],
range: NSRange(location:aDotRange.location + 4,
length: (price.count) - (aDotRange.location + 4) ))
self.attributedText = attString
}
}
Dummy code :
lblPrice.setAttributes(price: "$249.99 / mon")
lblPrice.layer.cornerRadius = 4
lblPrice.layer.borderWidth = 1.0
lblPrice.layer.borderColor = UIColor.blue.cgColor
lblPrice2.setAttributes(price: "$999.99 / 6 mo")
lblPrice2.layer.cornerRadius = 4
Output :
You can use UIViews and UILabels for designing the buttons and add tapGestures to the UIViews for User interactions.

I want to display a picker next to a textfield, when the user starts editig. After editing, the picker disappears.
Therefore I changed the width of a textfield like this in textFieldDidBeginEditing:
func textFieldDidBeginEditing(_ textField: UITextField)
{ print ("textFieldDidBeginEditing")
let newSize = CGSize(width: 90.0, height: textfield.frame.height)
let newFrame = CGRect(origin: textfield.frame.origin, size: newSize)
textfield.frame = newFrame
}
In textFieldDidEndEditing the width is reset to the old value.
This works fine the time (beginEditing, endEditing)
In following attempts the with is not changed again (the print statement is reached)
What´s going wrong.
Everything works fine in my test project, try insert textfield.setNeedsDisplay() after set new frame.

How to remove this white border around the angles in the shown button?
Create your button this way:
let button = UIButton(type: UIButtonType.system)
button.titleLabel?.font = UIFont.preferredFont(forTextStyle: UIFontTextStyle.body)
button.setTitleColor(UIColor.black, for: UIControlState.normal)
button.backgroundColor = UIColor.white
button.layer.cornerRadius = 4
