问题描述

我有四个tabBarItem.当用户单击第一个选项卡项目时，选项卡栏应被隐藏.其他三个选项卡栏应出现.这可能吗?

I have four tabBarItems. When a user clicks on the first tab item the tab bar should be hidden. The other three tab bars should appear. Is this possible?

推荐答案

预先警告:这是对选项卡栏的不寻常处理.

Warning up front: this is an unusual handling of tab bars.

如果将UITabBarItem连接为IBOutlet，并且还连接UITabBarController的委托，则在方法tabBarController:didSelectViewController中:您可以测试用户是否点击了感兴趣的标签栏. ，您可以将其title属性设置为@"，如果它有图像，则可以将其图像属性设置为nil.

If you hook up the UITabBarItem as an IBOutlet, and also hook up the UITabBarController's delegate, then in the method tabBarController:didSelectViewController: you can test to see if the user has tapped the tab bar you're interested in. If so, you can set it's title property to @"" and if it has an image you can set it's image property to nil.

这看起来有点奇怪-它会为您提供功能齐全的tabBarItem，基本上是透明的.

This will look sort of strange though - it will give you a fully functioning tabBarItem, that is basically transparent.

如果您确实希望tabBarItem消失，请通过将tabBarControllers.viewControllers属性重置为不包含要隐藏的viewController的数组，将其从tabBarController中移除.

If you really want the tabBarItem to disappear, remove it from the tabBarController, by resetting the tabBarControllers.viewControllers property to an array that does NOT contain the viewController you want to hide.
