You could try to load the NSData object in a UIIImage with the initData. Then check if the return UIImage object is nil. This is not full proof methods, but should work.

UIImage *im = [[UIImage alloc] initWithData:YourNSData];
UIImageView *imview;

// test to see if the image was successfully created
if (im){
   imview = [[UIImageView alloc] initWithImage:im];
}

Hope this helps
