Question

Please help me i have a NSMutableArray which contains data until viewDidLoad is finished.

When I click any button I try to get the data in it and it just disappears.

If you created your array with a variant of [NSMutableArray array] it will be autoreleased. Assuming myArray is a property of your class, you should use

myArray = [[NSMutableArray] alloc] init]; //or initWithCapacity, etc.

If you still use reference counting, you need to add [myArray retain]; unless it is already retained in the @property declaration and release it in viewDidUnload:.
