Answer 3

Code to coverting .GIF file can converted in NSdata -

NSString *pathForFile = [[NSBundle mainBundle] pathForResource: @"myGif" ofType: @"gif"];

NSData *dataOfGif = [NSData dataWithContentsOfFile: pathForFile];

NSLog(@"Data: %@", dataOfGif);

Answer 4

The key here is to save the GIF file or URL download directly into a NSData instead of making it a UIImage. Bypassing UIImage will let the GIF file keep the animation.

Here is some code to convert a GIF file into NSData:

NSString *filePath = [[NSBundle mainBundle] pathForResource: @"gifFileName" ofType: @"gif"];

NSData *gifData = [NSData dataWithContentsOfFile: filePath];

But in all honesty, you should really consider not using GIF at all.
