IOS SDK - 如何屏幕查看tableView的镜头内容？

Question

如何屏幕截图tableView的所有内容？(所有内容=可见区域+非可见区域)

我试过这个:

UIGraphicsBeginImageContext(self.tableView.bounds.size);
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage* image1 = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

self.imageView.image = image1;

但它不起作用,我的意思是它的截图只有可见区域:(

我解决了:))

这是代码:)

+ (UIImage *)captureView:(UIScrollView *)view inContentRect:(CGRect)rect{
    UIImage* image = nil;

    CGPoint savedContentOffset = view.contentOffset;
    CGRect savedFrame = view.frame;

    UIGraphicsBeginImageContextWithOptions(view.contentSize, 1, 0);
    view.contentOffset = CGPointZero;
    view.frame = CGRectMake(0, 0, view.contentSize.width, view.contentSize.height);

    [view.layer renderInContext: UIGraphicsGetCurrentContext()];
    image = UIGraphicsGetImageFromCurrentImageContext();

    view.contentOffset = savedContentOffset;
    view.frame = savedFrame;

    UIGraphicsEndImageContext();

    // after all of this, crop image to needed size
    return [Utils cropImage:image toRect:rect];                                 
}
