ios - UITextView.attributedText，如何设置numberOflines和lineBreakMode？

Question

在某些情况下，我必须使用 UITextView 而不是 UILabel(使链接属性可点击)。这是我的代码:

    let attributedString = NSMutableAttributedString(string: "TestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTestTest")
    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineBreakMode = .byTruncatingTail
    attributedString.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSMakeRange(0, attributedString.length))

这是我的 TextView :

private lazy var titleTextView: UITextView = {
    let view = UITextView(frame: .zero, textContainer: nil)
    view.isEditable = false
    view.textContainerInset = .zero
    view.textContainer.lineFragmentPadding = 0
    view.textContainer.maximumNumberOfLines = 2        // Set numberOflines here!
    view.textAlignment = .left
    view.isScrollEnabled = false
    view.delegate = self

    return view
}()

但是 maximumNumberOfLines 属性不起作用，它只显示 1 行，然后是“...”

您需要将 lineBreakMode 设置为不截断的值。

尝试

paragraphStyle.lineBreakMode = .byWordWrapping
