裁剪截图并保存图像

Question

I'm using this code to take a screenshot of my specific UIView which is inside in my main view.

UIGraphicsBeginImageContextWithOptions(_myView.frame.size, NO, [UIScreen mainScreen].scale);
[self.view drawViewHierarchyInRect:self.view.bounds afterScreenUpdates:YES];
UIImage *imageSave = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Main view size is (0,0,320,480) lets say, and myView size is (10,20,200,150)

Now i would like to capture/take a screenshot only of myView.

The above code doesn't capture exactly how i want, any suggestions?

Try this, it works for me.

- (UIImage *)snapshotOfView:(UIView *)view
{
    UIGraphicsBeginImageContext(view.bounds.size);

    [view.layer renderInContext:UIGraphicsGetCurrentContext()];

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

    return viewImage;
}
