iOS UIImageJPEGRepresentation error: Not a JPEG file: starts with 0xff 0xd9

Question

I am writing a .jpg file to my app\'s Documents directory like this:

NSData *img = UIImageJPEGRepresentation(myUIImage, 1.0);
BOOL retValue = [img writeToFil         


        

Answer 1

The images were not corrupt, I was able to display them correctly. The issue is possibly a bug in UIImage, or perhaps the documentation should be more clear about using imageWithContentsOfFile:.

I was able to eliminate the error message by changing

UIImage *myImage = [UIImage imageWithContentsOfFile:path];

to

NSData *img = [NSData dataWithContentsOfFile:path];
UIImage *photo = [UIImage imageWithData:img];
