当用户点击iPhone中的上方视图时隐藏UIActionSheet

Question

我想在操作表上设置操作,以便当用户点击操作表的上方时,它会被解雇.
我想要这个,因为我不想在动作表中添加取消按钮.用户可以通过点击休息区视图来取消操作表,而不是取消按钮.
任何建议如何在iPhone中执行此操作.
谢谢

// For detecting taps outside of the alert view
-(void)tapOut:(UIGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self];
    if (p.y < 0)
    {   // They tapped outside
        [self dismissWithClickedButtonIndex:0 animated:YES];
    }
}

-(void) showFromTabBar:(UITabBar *)view
{
    [super showFromTabBar:view];

    // Capture taps outside the bounds of this alert view
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapOut:)];
    tap.cancelsTouchesInView = NO; // So that legit taps on the table bubble up to the tableview
    [self.superview addGestureRecognizer:tap];
    [tap release];
}

看到这里.

请注意,这已经发生在iPad上.
