Answer 1

试试这个:

在 Swift 中:

    let fixedWidth = textView.frame.size.width
textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
var newFrame = textView.frame
newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
textView.frame = newFrame;
