创建自定义的触摸手势来实现对键盘的隐藏：

 

- (void)viewDidLoad  
{  
    [super viewDidLoad];  
    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(keyboardHide:)];  
    //设置成NO表示当前控件响应后会传播到其他控件上，默认为YES。  
    tapGestureRecognizer.cancelsTouchesInView = NO;  
    //将触摸事件添加到当前view  
    [self.view addGestureRecognizer:tapGestureRecognizer];  
}  
  
-(void)keyboardHide:(UITapGestureRecognizer*)tap{  
    [textFiled resignFirstResponder];  
}
