Answer 1

try this...

- (UIImage*)captureView:(UIView *)view 
{
    CGRect rect = [[UIScreen mainScreen] bounds];
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [view.layer renderInContext:context];
    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img;
}

- (void)saveScreenshotToPhotosAlbum:(UIView *)view 
{
    UIImageWriteToSavedPhotosAlbum([self captureView:self.view], nil, nil,nil);
}
