Answer 1

Get rotated image using following code, and use final image

UIGraphicsBeginImageContext(thumbnail.size);//thumbnail is your original image
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextRotateCTM (context, radians(90));//set rotation as per your requirement
[thumbnail drawAtPoint:CGPointMake(0, 0)];
UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext();//image after rotation
