UIScroll的改动内容 参考
原标题:Convert content of UIScrollView in UIImage

在我的申请中,用户可添加<代码>。 UIImageView,作为我的子目。 当用户将“Save”纽芬兰带上“Save”,我想将我的<编码>UIScrollView的所有内容作为<代码>UIImage <输入光图书馆。

我一直在研究谷歌,但这个主题并不多。

        CGRect rect = self.mainView.frame;
        [self.mainView setFrame:CGRectMake(0, 0, 824, self.mainView.contentSize.height)];
        UIGraphicsBeginImageContext(self.mainView.bounds.size);
        [self.mainView.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        UIImageWriteToSavedPhotosAlbum(image , nil, nil, nil);
        [self.mainView setFrame:rect];

象你需要筛查的灰色,你可以尝试在已经采取行动时执行这一守则。

UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * data = UIImagePNGRepresentation(image);
[data writeToFile:@"myImage.png" atomically:YES];
