how to hide keyboard in UIViewController on return button click->iphone
提问by Csabi
Hi I find some questions like that but they talk about textView, I have ViewController, with scrollView where are 6 textfield and one textView I want a function which makes the keyboard disappear on on done/return button click.I implemented functions resign to first responder, which hide my keyboard when i click outside of scrollView, but that is not exactly i want, because i like to make it disappear on button click too.
嗨，我发现了一些类似的问题，但他们谈论的是 textView，我有 ViewController，带有 scrollView，其中有 6 个文本字段和一个 textView 我想要一个功能，使键盘在完成/返回按钮点击时消失。我实现了功能辞职给第一响应者，当我在 scrollView 外部单击时隐藏我的键盘，但这并不是我想要的，因为我也喜欢让它在单击按钮时消失。
THanks for any help
谢谢你的帮助

Set up a class that conforms to the UITextFieldDelegate protocol and make the delegate of your text fields an instance of this class. Implement the method:
设置一个符合 UITextFieldDelegate 协议的类，并使文本字段的委托成为此类的实例。实现方法：
- (BOOL)textFieldShouldReturn:(UITextField *)textField
As follows:
如下：
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}

Hi i found it out so the point with textfields is to add this lines at viewdidload:
嗨，我发现了，所以文本字段的重点是在 viewdidload 中添加以下行：
textFieldOne.returnKeyType = UIReturnKeyDone;
textFieldCislo.delegate = self;
textFieldTwo.returnKeyType = UIReturnKeyDone;
textFieldCislo.delegate = self;
...
And this implement method :
这个实现方法：
-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == textFieldOne) {
[textFieldOne resignFirstResponder];
}
...
}

After quite a bit of time hunting down something that makes sense, this is what I put together and it worked like a charm.
经过相当长的时间寻找有意义的东西后，这就是我放在一起的东西，它就像一个魅力。

U can use this method to hide the keyboard by clicking any where in the view
您可以使用此方法通过单击视图中的任何位置来隐藏键盘
