Question

I’m quite new to iOS/Objective-C Developing and I’m writing my first serious iPhone/iPad App. The App that I am building is Tab-Based. There’s a Settings-Tab which manages some Settings of a Picker used in the other view.
To my question: I want the picker to reload all components when the Tab changed or the settings in s selectorview changed. How would you solve this?

Thanks,

Answer 1

Tab-Bar based apps handle the tab change event using any of the following delegate methods:

 – tabView:shouldSelectTabViewItem:
 – tabView:willSelectTabViewItem:
 – tabView:didSelectTabViewItem:

you can call the PickerView refreshing methods in any of the above(preferably the first and second ones). Reference

Hope this helps. For any further help, please add comments
