Changing orientation error IOS

Question

I am having an exception while trying to change orientation. I can't seem to get through this exception. the exception itself does not help because it keeps on pointing to the line of code that allows me to change orientation but the description says attempt to insert nil from objects[0] which indicates error in inserting to an array. I tried exception breakpoint and instruments in debugging. also had nszombie turned on. also made sure to check if nil before adding to an array or initializing an array. so i dont know anymore what could be the problem or what sort of action i would do to fix this. as for the array i have an array named arraydata that is initialized at viewdidload. when it is nil and/or count < 1. i call upon a af response that populates the array so it is made sure that it has content. also the logs are fine it returns count > 0 always. anyways I hope someone can help here is the exception. Thanks in advance

Initializing the array at viewDidLoad

self.arrayData = [[NSMutableArray alloc]init];

at an initializing method

if(StreamList!=nil && StreamList.count > 0)
self.arrayData = [NSMutableArray arraywithArray:StreamList];

where StreamList is an nsarray containing objects

Answer 1

OK I have figured out a solution for you. Just implement this method exactly like it is:

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {}
