推荐答案
首先,您需要确认UITextFieldDelegate然后设置you textField like yourTextField.delegate = self
add
yourTextField.resignFirstResponder()
First you need to confirm to UITextFieldDelegate and then set you textField like yourTextField.delegate =self
add
yourTextField.resignFirstResponder()
到你的代码。将resignFirstResponder调用yourTextField。
你也可以使用下面的代码(根据你的需要)。
to your code. Call resignFirstResponder to yourTextField. and you can also use below code (According to your need).
在委托方法 textFieldDidEndEditing(textField:UITextField)
检查(如果)是否有某些值/文本不是。
In delegate method textFieldDidEndEditing(textField: UITextField)
with checking (if) whether it has some value/text of not.
yourTextField.attributedPlaceholder = NSAttributedString(string:用户名,属性:[NSForegroundColorAttributeName:UIColor.whiteColor()])textUserName.resignFirstResponder()
