问题描述

如何在ScrollView触摸事件中隐藏键盘...

How can I hide the keyboard on ScrollView touch event...

场景就像那样......

Scenario is like that...

- >查看 - > ScrollView - > Textfield

->View ->ScrollView ->Textfield

我想在触摸时隐藏键盘的scrollView。我试图覆盖滚动视图的类但仍然无法做到。

I want to hide the keyboard on touch of scrollView. I tried to override the class for scrollview but still i can't do it.

推荐答案

这样做会有所帮助：

@interface MyClass <UIScrollViewDelegate> {
}

@implementation

- (void)viewDidLoad {
  yourScrollView.delegate = self;
}

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
  [myTextField resignFirstResponder];
}

如果你真的想要处理触摸事件，那么你需要子类化UIScrollView并覆盖方法：

If you really want to handle the touch event, then you need to subclass the UIScrollView and override the method:

- (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view {

}
