在ScrollView Touch上重新启动First Responder

Question

如何在ScrollView触摸事件中隐藏键盘...

情景就是这样......

  

- ＆gt;查看 - ＆gt; ScrollView - ＆gt; Textfield

我想在触摸scrollView时隐藏键盘。我试图覆盖scrollview的类，但我仍然无法做到。

Answer 1

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：

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

}

这对我有用

在viewController的viewDidLoad-method

中

    UITapGestureRecognizer *tapScroll = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapped)];
    tapScroll.cancelsTouchesInView = NO;
    [viewScroller addGestureRecognizer:tapScroll];

其中viewScroller是您的滚动条。在我们的tapped方法中

    - (void) tapped {
        [self.view endEditing:YES];
    }

不知道为什么，但上述内容对我不起作用......即使它应该

Answer 3

试试这个：

为scrollview添加手势识别器，

UITapGestureRecognizer *tapScroll = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped)];
    tapScroll.cancelsTouchesInView = NO;
    [yourScrollview addGestureRecognizer:tapScroll];
    [tapScroll release];

将键盘重新设置为（tapped :)方法。
