Swift 3标签栏禁用标签 [英] Swift 3 tab bar disable tab

问题描述

我创建了一个包含5个标签的标签栏.我们想要创建一个功能，使我们可以通过编程方式启用/禁用选项卡栏的某些选项卡，以使用户无法单击它.

I have created a tab bar with 5 tabs. we want to create a feature that we can enable/disable some tabs of tab bar programmatically so that user will not able to click on it.

我们使用了默认的标签栏控制器，而我们使用的是swift3.有人知道如何管理这些东西吗?

We have used default tab bar controller and we are using swift 3. Does anyone have an idea how to manage this stuff?

我尝试了很多方法，但是似乎无法限制用户单击选项卡.

I have tried many ways but it seems that it's not possible to restrict the user to click on the tab.

请让我知道是否有人面对并解决了这个问题.

Please let me know if anyone has faced and solved this issue.

推荐答案

let tabBarControllerItems = self.tabBarController?.tabBar.items

if let tabArray = tabBarControllerItems {
    tabBarItem1 = tabArray[0]
    tabBarItem2 = tabArray[1]

    tabBarItem1.isEnabled = false
    tabBarItem2.isEnabled = false    
}

只需将上面的代码块放在供初学者使用的viewDidLoad()方法中，别忘了创建tabBarItem变量

Just put the block of code above in the viewDidLoad() method for starters and don't forget to create the tabBarItem variables
