Answer 1

Rotate Image by 90 degree (clockwise/anti-clockwise direction)

Function call -

 UIImage *rotatedImage = [self rotateImage:originalImage clockwise:YES];

Implementation:

- (UIImage*)rotateImage:(UIImage*)sourceImage clockwise:(BOOL)clockwise
  {
    CGSize size = sourceImage.size;
    UIGraphicsBeginImageContext(CGSizeMake(size.height, size.width));
    [[UIImage imageWithCGImage:[sourceImage CGImage]
                         scale:1.0
                   orientation:clockwise ? UIImageOrientationRight : UIImageOrientationLeft]
                   drawInRect:CGRectMake(0,0,size.height ,size.width)];

   UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
   UIGraphicsEndImageContext();

   return newImage;
  }
