        CGSize newImageSize = CGSizeMake(cropImage.frame.size.width, cropImage.frame.size.height);
        if (UIGraphicsBeginImageContextWithOptions != NULL) {
            UIGraphicsBeginImageContextWithOptions(newImageSize, NO, [[UIScreen mainScreen] scale]);

    // Draw image1
    [maskImage.image drawInRect:CGRectMake(0,0, maskImage.frame.size.width,maskImage.frame.size.height)];
    // Draw image2
    [cropImage.image drawInRect:CGRectMake(cropImage.frame.origin.x, cropImage.frame.origin.y, cropImage.frame.size.width, cropImage.frame.size.height)];

Try this piece of code

//Hide your views here like save button
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    UIGraphicsBeginImageContext(screenRect.size);
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, self, nil, nil);  
 //Show again your hidden views here like save button
