滚动视图上的Xcode键盘问题

Question

我有顶部单一视图上的滚动视图。我有一些文本框和UIPickers就可以了。现在我知道如何在按下返回键时使键盘熄灭。但是，我试图在轻按背景或选择UIpicker时从文本字段中取消键盘。我试着这样做......

接口：

- (IBAction)textFieldReturn:(id)sender; 
    - (IBAction)backgroundTouched:(id)sender; 

实现：

-(IBAction)textFieldReturn:(id)sender 
{ 
     [sender resignFirstResponder]; 
} 

-(IBAction)backgroundTouched:(id)sender 
{ 
     [textField resignFirstResponder]; 
} 

但问题是我不能让sroll视图控制类型使其工作..

Answer 1

试着像这可能是它可以帮助你，但不知道，

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ 
    UITouch *touch = [[event allTouches] anyObject]; 
     if (![[touch view] isKindOfClass:[UITextField class]]) { 
      [yourtextfield resignFirstResponder]; 
     } 
} 

而且用于获取关于滚动视图，你必须采取geasture的再认识触摸事件，

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap)]; 
    [scroll addGestureRecognizer:singleTap]; 

-(void)singleTap{ 
     [text resignFirstResponder]; 
     //write whatever you want it. 
    }
