Question

嗨我发现了一些像这样的问题，但他们谈的是textView，我有ViewController，其中有scrollView，其中有6个textfield和一个textView，我想要一个功能，让键盘在完成/返回按钮上消失。我实现了函数辞职第一个响应者，当我点击scrollView外面时隐藏我的键盘，但这不是我想要的，因为我喜欢让它在按钮点击时消失。

感谢任何帮助

Answer 1

设置符合UITextFieldDelegate协议的类，并使文本字段的委托成为此类的实例。实施方法：

- (BOOL)textFieldShouldReturn:(UITextField *)textField

如下：

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

Answer 2

嗨我发现了，所以textfields的意思是在viewdidload上添加这行：

textFieldOne.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
textFieldTwo.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
...

这个实现方法：

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

    if (theTextField == textFieldOne) {
        [textFieldOne resignFirstResponder];
    }
...
}
