如何在UIScrollView中为键盘实现ResignFirst Responder？

Question

  

可能重复：
  Dismiss keyboard on touch anywhere outside UITextField

我在我的应用中使用UIScrollView。我正在放几个文本字段和按钮。我想在文本框外触摸时隐藏键盘。 （我的意思是他们会录制uiscrollview）。我尝试过很多东西......我使用的是UIGestureRecognizer，但它不起作用......请帮忙

Answer 1

这是刚刚尝试的解决方案，它的工作原理......希望帮助

将以下代码添加到viewDidLoad;

-(void)viewDidLoad {
    //create a tapGesture which calls a removeKeyboard method
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removeKeyboard)];

    tapGesture.cancelsTouchesInView = NO;

    [self.yourScrollView addGestureRecognizer:tapGesture];
}

-(void)removeKeyboard {
    [self.yourTextField resignFirstResponder];
}

希望有所帮助......

在您的视图中尝试以下代码...

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