Use this method and pass image, rect as parameter. You can specify y offset and x offset in cropRect

-(UIImage *)cropImage:(UIImage *)image rect:(CGRect)cropRect
{
   CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], cropRect);
   UIImage *cropedImg = [UIImage imageWithCGImage:imageRef]; 
   CGImageRelease(imageRef);
   return cropedImg;
}

Check Below Code:

-(UIImage *)imageWithImageSimple:(UIImage*)image scaledToSize:(CGSize)newSize
{

UIGraphicsBeginImageContext(newSize); 

[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];  

UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();   

UIGraphicsEndImageContext();   

return newImage;
}
