objective c - How to call the viewDidLoad in different time? -


I want to ask a question about the iPhone application.

In my program, I am making the UITBBR Controller with 4 tabs. 4 tabs display different information and there are some connections. When I do something in Tab 4, it will update some data that is displayed in 1 tab. However, the page is the same, if I add the element to the viewDidLoad function.

My problem is how do users load data every time they press the tab? Do I need to move the code from somewhere? [UIViewController viewWillAppear:] Looking exactly for what you are doing.

But I do not think the code is capable of changing the color of each variable declared....
