Converting GIF images to nsdata

问题:

I have an iPhone application that needs to save an image onto the database in BLOB format. The problem is that if the image is in .gif format then it cannot be converted to NSDATA format and hence i am not been able to save that onto the database in BLOB format.

What should I do?

Please help with some code..

Thanks in advance Joy

A gif image can be converted into NSData...Here's the code snippet:

NSString *pathForGif = [[NSBundle mainBundle] pathForResource: @"gifFile" ofType: @"gif"];

NSData *gifData = [NSData dataWithContentsOfFile: pathForGif];

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

The log looked something like this:
