objective-c - UITextField 委托(delegate)

Question

我有一个 UITextFiled，我向其应用委托(delegate)以通过按“完成”关闭键盘。

    ...
    textfield.returnKeyType = UIReturnKeyDone;
    textfield.delegate = self;
    ....

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

    [textField resignFirstResponder];
    return YES;
}

我如何在按下“完成”时调用方法？

Answer 1

这就是你想要的吗？

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    [add your method here];
    return YES;
}
