滾動視圖上的Xcode鍵盤問題

Question

我有頂部單一視圖上的滾動視圖。我有一些文本框和UIPickers就可以了。現在我知道如何在按下返回鍵時使鍵盤熄滅。但是，我試圖在輕按背景或選擇UIpicker時從文本字段中取消鍵盤。我試着這樣做......

接口：

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

實現：

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

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

但問題是我不能讓sroll視圖控制類型使其工作..

試着像這可能是它可以幫助你，但不知道，

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

而且用於獲取關於滾動視圖，你必須採取geasture的再認識觸摸事件，

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

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