我一直关注Custom Clear Button此处发布的扩展解决方案
清除按钮将在我输入文本字段后立即输入。这是不正确的行为。清除按钮应仅在键入文本时显示。该如何解决?
我正在从viewWillAppear的文本字段中调用applyCustomClearButton
。
extension UITextField {
// Custom Clear Button
func applyCustomClearButton() {
clearButtonMode = .never
rightViewMode = .whileEditing
let clearButton = UIButton(frame: CGRect(x: 0, y: 0, width: 16, height: 16))
clearButton.setImage(UIImage(named: "Glyph/16x16/Clear")!, for: [])
clearButton.addTarget(self, action: #selector(clearClicked), for: .touchUpInside)
rightView = clearButton
}
@objc func clearClicked(sender:UIButton) {
text = ""
}
}
答案 0 :(得分:0)
我有一种直觉,就是您没有调用applyCustomClearButton()
函数。
为此,请转到具有您的UITextfield的viewcontroller并调用:
yourTextField.applyCustomClearButton()
