Im making an attempt to make messages alike TextField which is one line tall and its most peak is 5 traces. When person reaches its most peak (5 traces), scrolling can be enabled and TextField will cease its peak enlargement.
I’ve this piece of code, which is doing peak enlargement on every newline, however doesn’t cease, when person reaches 5 traces peak and doesn’t allow scrolling:
struct AutoAdjustingTextView: UIViewRepresentable {
@Binding var textual content: String
func makeUIView(context: Context) -> UITextView {
let textView = UITextView()
textView.isScrollEnabled = false
textView.font = UIFont.systemFont(ofSize: 17)
textView.delegate = context.coordinator
textView.textContainerInset = .zero
textView.textContainer.lineFragmentPadding = 0
textView.setContentHuggingPriority(.defaultHigh, for: .vertical)
return textView
}
func updateUIView(_ uiView: UITextView, context: Context) {
uiView.textual content = textual content
updateTextViewHeight(uiView)
}
non-public func updateTextViewHeight(_ textView: UITextView) {
let measurement = textView.sizeThatFits(CGSize(width: textView.body.width, peak: .greatestFiniteMagnitude))
if textView.body.measurement.peak != measurement.peak {
textView.body.measurement.peak = measurement.peak
}
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, UITextViewDelegate {
var mum or dad: AutoAdjustingTextView
init(_ mum or dad: AutoAdjustingTextView) {
self.mum or dad = mum or dad
}
func textViewDidChange(_ textView: UITextView) {
mum or dad.textual content = textView.textual content
mum or dad.updateTextViewHeight(textView)
}
}
}
Im operating on IOS 14
