Try this

NSData *imageData  = [UIImageJPEGRepresentation(self.photoImageView.image, compression)  dataUsingEncoding:NSUTF8StringEncoding];

const unsigned char *bytes = [imageData bytes]; 
NSUInteger length = [imageData length];
NSMutableArray *byteArray = [NSMutableArray array];
for (NSUInteger i = 0; i length; i++)
{
    [byteArray addObject:[NSNumber numberWithUnsignedChar:bytes[i]]];
}

NSDictionary *dictJson = [NSDictionary dictionaryWithObjectsAndKeys:
              byteArray, @"photo",
              nil];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictJson options:0 error:NULL];
