例子：

設定一個背景檢視

DoModalView = [[UIViewalloc]initWithFrame:[UIScreenmainScreen].bounds];

DoModalView.backgroundColor = [UIColorcolorWithRed:0.3green:0.3blue:0.3alpha:0.6];

新增手勢

    UITapGestureRecognizer * tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removesubViews)];tapGesture.delegate

= self;

    [DoModalViewaddGestureRecognizer:tapGesture];

方法實現

- (void)removesubViews

{

    [lockapplyTabviewremoveFromSuperview];

    [DoModalViewremoveFromSuperview];

}

衝突解決（避免tabview，textfield等的手勢不響應）

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch

*)touch{

    if ([touch.view isKindOfClass:[UITextField class]])

    {

        return NO;

    }

// 若為UITableViewCellContentView（即點選了tableViewCell），則不截獲Touch事件

if ([NSStringFromClass([touch.viewclass]) isEqualToString:@"UITableViewCellContentView"]) {

        return NO;

    }

return YES;

}
