Question

In my app i am using tabbar controller with 5 tabs,in 3 tabs,when click on a button it calls one View Controller. I am using same view controller for those 3 tabs so i am getting problem while calling same view in different tabs,So while changing the tab i dont want to call ViewWillAppear method. So what i have do? or else how to find previous selected index of the tabbar controller?

Thanks in Advance

I think you are not familiar with iOS Development.

1. In a TabbarController we can specify as much of UIViewcontroller/UINavigationController object.
2. if we need to re-use a UIViewcontroller you need to tag the view controller using a property object.
3. You need to use different instance of UIViewController for different tab.
4. While Showing a UIViewController its viewWillAppear got fired. we don’t able to remove this behavior. But in most case we can handle such case with viewDidLoad (It is called once for an instance of view controller).
5. if we need to track the previously selected tab item we need to do our own work-around by using a shared class or static variable.
