IOS Default.png show every time when my app enter foreground from background [duplicate]

Question

I'm new to IOS development.

I set a Default.png file, and it is shown every time when the app enter foreground from background, but I just want Default.png is shown once when the app launch.

Answer 1

I observed that whenever application is resumed from background, iOS 5.0 simulator showed the default image or launch image, whereas iOS 4.3 simulator showed the screenshot of the application, when it was entering background.

Answer 2

For those seeking answer, it might be a case that your app didn't finish a task you set up to do when it enters background. It will finish it and resume, or if you will wait long enough in background the task will be completed and app will enter foreground as expected.
