介绍:
- UITextField和UITextView设置最大输入长度
- UITextField和UITextView限制输入emoji表情
- 为UITextView添加占位字符
使用:
- ZMTextField
private lazy var textField: ZMTextField = {
let textField = ZMTextField(frame: CGRect(x: 50, y: 160, width: view.frame.size.width - 100, height: 50))
textField.backgroundColor = UIColor.gray
textField.maxLength = 11 // 最大输入长度
textField.isRemoveEmoji = true // 是否输入emoji,默认false(可以输入emoji)
textField.placeholder = "最大输入11位,禁止输入emoji"
return textField
}()
/// 文本改变回调
textField.didValueChange = { textField in
debugPrint("textField: \(textField.text ?? "")")
}
/// 文本达到最大长度的回调
textField.didMaxLength = { textField in
debugPrint("textField max")
}
- ZMTextView
private lazy var textView: ZMTextView = {
let textView = ZMTextView(frame: CGRect(x: 50, y: 220, width: view.frame.size.width - 100, height: 200))
textView.backgroundColor = UIColor.gray
textView.textColor = UIColor.white
textView.maxLength = 11 // 最大输入长度
textView.isRemoveEmoji = true // 是否输入emoji,默认false(可以输入emoji)
textView.placeholder = "占位字符" // 占位字符
textView.placeholderColor = UIColor.red // 占位字符颜色
return textView
}()
/// 文本改变回调
textView.didValueChange = { textField in
debugPrint("textField: \(textField.text ?? "")")
}
/// 文本达到最大长度的回调
textView.didMaxLength = { textField in
debugPrint("textField max")
}
