根据故事板中导航控制器的不同按钮调用相同标签栏控制器的特定选项卡

Question

My Application's Workflow:

Here, I have 1 one Main Navigation Controller .Then, it push to 1 Tabbar Controller & 2 View Controllers .
Main Tabbar Controller has 2 different navigation controllers for individual functionalities.

Now, I want to navigate to Main Tabbar from button 1 & button 2.
When I pressed, button 1, it will shift to 2nd Tab & when I pressed button 2, it will shift to 3rd tab as I described in an image.

I am using self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:1]; code for shifting tab.

It's shifting, but not calling ViewDidLoad method of that class & not loading data accordingly.

So, how to call particular tab based on button's click ??

Any suggestions will be appreciated.

Thanks in advance.

Answer 1

您需要尝试使用以下代码段

<tabbar_controller_object>.selectedIndex = <YOUR_tab_no_to_select>;

Answer 2

You can use self.tabBarController.selectedIndex = yourIndex; as Foram Mukund Shah has said.

But, as you want to change the index, you need to write this code in viewDidAppear rather than on viewDidLoad it is not changing because you are trying to change index before your tabbar is loaded.

So, please try to put your code in viewDidAppear .

It will resolve your issue.
