[英]Showing a overlaying menu when tab bar item is clicked - IOS

Thanks for reading my question! 感谢您阅读我的问题！

I have a 5-part tabbar which I use for app navigation, the center tab is covered by a UIButton and is slightly larger (much like the instagram app). 我有一个5部分的标签栏，可用于应用程序导航，中间的标签页由UIButton覆盖，并且稍大一些（非常类似于instagram应用程序）。 This works fine. 这很好。

But what I want is the far right tab bar item to show a overlaying menu when clicked. 但是我想要的是最右边的选项卡栏项目，当单击该选项卡时显示一个覆盖菜单。 I don't want it to switch to a viewcontroller with a menu. 我不希望它切换到带有菜单的viewcontroller 。 I want the menu to be displayed no matter which of the other views you're in at the moment. 无论您当前处于哪个其他视图中，我都希望显示菜单。 So I want it to act much like a button which is in the tabbar. 因此，我希望它的行为就像标签栏中的按钮一样。 But I have no idea how to go about doing this. 但是我不知道该怎么做。

Should I use a overlaying button over the tabbaritem or should I catch the tabbarclick, but how can I prevent the view from changing in that case? 我应该在tabbaritem使用覆盖按钮还是应该捕获tabbarclick，但是在这种情况下如何防止视图更改？

Thanks you for any help! 感谢您的帮助！

You need to implement UITabBarDelegate . 您需要实现UITabBarDelegate 。 Then override tabBar:didSelectItem: and implement your custom displaying here. 然后覆盖tabBar:didSelectItem:并在此处实现您的自定义显示。 See below for reference 请参阅下面的参考

Then i would just make a custom UIView and fade it in when that specific tagged UITabBarItem is pressed. 然后，我只想制作一个自定义UIView并在按下该特定标记的UITabBarItem时使其淡入。
