所以我从 github使用这个 Menu.目前,如果再次单击“点击”按钮,菜单会打开并缩回,但如果用户点击除按钮之外的屏幕上的任何其他位置,我还希望菜单缩进.我遇到的问题是我在带有tabbar
以下是它现在如何工作的示例.这是link to the Code.
第一种方法:
您可以为按钮和其他视图设置一个标签,这些视图不希望在敲击菜单时将其关闭:
button.tag=99; button2.tag=99; backgroundImage.tag=99;
然后在viewcontroller中,使用touchesBegan:withEvent:delegate
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; if(touch.view.tag!=99){ //Call your dismiss method } }
第二种方法:
如果您的按钮有一个叠加层(例如突出显示按钮的背景,并填满整个视图),您可以为其添加UITapGestureRecognizer,并在每次希望显示自定义视图时将其添加到视图中.这是一个例子:
UIView *overlay; -(void)addOverlay{ //Add the overlay, if there's one in your code, then you don't have to create this overlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)]; [overlay setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:0.5]]; //Register the tap gesture recognizer UITapGestureRecognizer *overlayTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onOverlayTapped)]; [overlay addGestureRecognizer:overlayTap]; [self.view addSubview:overlay]; } - (void)onOverlayTapped { //Call your dismiss method for (UITapGestureRecognizer *ges in previewOverlay.gestureRecognizers) { [overlay removeGestureRecognizer:ges]; } [overlay removeFromSuperview]; }
