Hello!
I'm trying to use a UILabel in a tree of SwiftUI views, creating a View Struct that conforms to UIViewRepresentable. The reason for using UILabel instead of the native SwiftUI Text() view is that I would like to display an NSAttributedString.
The UILabel renders in the SwiftUI view, however the words do not wrap to become multi-line on the screen. Instead, the text just chops off at the trailing edge. The same UILabel settings in a purely UIKit based ViewController setup wrap correctly, for comparison. Providing a plain string to UILabel.text or an attributed string to UILabel.attributedText yields the same non-wrapping results.
I am just wondering if anyone has got this to work, or knows where I might be going wrong? Here is the view struct:
struct UIKitLabelView : UIViewRepresentable {
typealias UIViewType = UILabel
func makeUIView(context: UIViewRepresentableContext<UIKitLabelView>) -> UILabel {
let label = UILabel()
label.translatesAutoresizingMaskIntoConstraints = false
label.lineBreakMode = .byWordWrapping
label.numberOfLines = 0
label.text = "a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20"
return label
// The text above should easily wrap on any character boundary, but is just chopped off at the "1" which is the character right before the edge of the device's screen.
}
func updateUIView(_ uiView: UILabel, context: UIViewRepresentableContext<UIKitLabelView>) {
}
}Here is the SwiftUI view hierarchy that embeds the UIKitLabelView at line 13:
struct MyView: View {
var body: some View {
ScrollView {
VStack(alignment: .leading, spacing: nil) {
Text("Title")
Divider()
UIKitLabelView()
Spacer()
.navigationBarTitle("My View")
}
.padding(20)
}
}
}Thanks in advance for your help!
