- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{

    //获取触摸对象

    UITouch *touch = [touches anyObject];

        //延迟调用

        [self performSelector:@selector(signedTouch) withObject:nil afterDelay:.35];

    }

    if (touch.tapCount == 2) {

        //取消单击事件,取消所有的单击事件

        [NSObject cancelPreviousPerformRequestsWithTarget:self];

        [self doubleTouch];

    }

    

}

    self.view.backgroundColor = [UIColor brownColor];

}
