触摸键盘辞职 [英] Resigning keyboard on touch

问题描述

我发现一些代码可以帮助我在用户触摸UITextView元素的屏幕时重新键盘。

I've found some code that helps me resign the keyboard when a user touches the screen off of the UITextView element.

以下是它的外观：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [[event allTouches] anyObject];
if([self.speechBubble.speechText isFirstResponder] && [touch view] != self.speechBubble.speechText){
    [self.speechBubble.speechText resignFirstResponder];
}
[super touchesBegan:touches withEvent:event];
}

到目前为止，此功能完美无缺，如果用户触及任何地方，将会移除键盘在文本视图之外。但是，它只适用于我正在运行它的特定对象，所以如果我有两个speechBubbles，它将无法工作。

This works perfectly so far, and will remove the keyboard if a user touches anywhere outside of the text view. However, it only works for the particular object that I'm running it for, so if I have two speechBubbles, it won't work.

如何更改此这样任何speechBubble会有同样的效果吗？ （我可以将此代码从我的ViewController移动到我的SpeechBubble类，但我对如何使用[touch view]在speechBubble视图之外进行触摸有一点问题。）谢谢

How can I change this so that ANY speechBubble will have the same effect? (I could move this code from my ViewController to my SpeechBubble class, but I'd have a little issue with how to use [touch view] to get touches outside of the speechBubble's view. ) Thanks

推荐答案

我刚刚发现的一些可能对您有用的东西是：

Something I just discovered recently that may be of use to you is:

[self.view endEditing:YES];

它将从当前拥有它的任何元素中辞退第一响应者，而无需手动跟踪它你自己。

It will resign first responder from any element that currently has it without you having to manually keep track of it yourself.

参考你的示例代码，这样的事情可能有用，这取决于你的speechBubbles如何工作：

In reference to your example code, something like this might work, depending on how your speechBubbles work:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
  UITouch *touch = [[event allTouches] anyObject];
  // Note the '!':
  if(![[touch view] class] isKindOfClass [speechBubble class]]){
    // It's not a bubble they touched, dismiss the keyboard:
    [self.view endEditing:YES];
  }
  [super touchesBegan:touches withEvent:event];
}
