In my project, I am using swift 3.0. Right now I am using following class (UILabel subclass) to adjust font size based on UILabel frame height. When UILabel frame change occurs, layoutSubviews recalculates proportional font size.
class Label: UILabel {
// FIXME: - properties
var fontSize: CGFloat = 0
var frameHeight: CGFloat = 0
// FIXME: - proportional font size adjustment
override func layoutSubviews() {
super.layoutSubviews()
font = font.withSize(frame.size.height * (fontSize / frameHeight))
}
}
HOW TO USE:
private let id: Label = {
let label = Label()
label.textAlignment = .left
label.numberOfLines = 1
label.font = UIFont.systemFont(ofSize: 17, weight: .semibold)
label.textColor = UIColor(hex: 0x212121, alpha: 1)
label.fontSize = 17
label.frameHeight = 20
label.clipsToBounds = true
return label
}()
Now I want to show some part of String in UILabel as BOLD TEXT and remaining in REGULAR TEXT. So I have found some help on this thread: Making text bold using attributed string in swift
I am using "Prajeet Shrestha's" extension for NSMutableAttributedString.
// "Prajeet Shrestha's" extension
extension NSMutableAttributedString {
func bold(_ text:String) -> NSMutableAttributedString {
let attrs:[String:AnyObject] = [NSFontAttributeName : UIFont(name: "AvenirNext-Medium", size: 12)!]
let boldString = NSMutableAttributedString(string:"\(text)", attributes:attrs)
self.append(boldString)
return self
}
func normal(_ text:String)->NSMutableAttributedString {
let normal = NSAttributedString(string: text)
self.append(normal)
return self
}
}
But I am not getting how I can change font size of this NSMutableAttributedString, when UILabel frame change occurs?
Any help appeciated.
