问题描述

我有以下代码可预览PDF文件:

I have this code which previews the PDF file:

QLPreviewController *previewController=[[QLPreviewController alloc]init];
previewController.delegate=self;
previewController.dataSource=self;
[self presentModalViewController:previewController animated:YES];

现在，当我关闭QLPreviewController或previewController时，此方法称为:

Now, when I close QLPreviewController or previewController this method is called:

- (void)previewControllerDidDismiss:(QLPreviewController *)controller {
    NSLog(@"You closed the document");
}

现在，当我调用此方法时，如何返回文档或Pdf的URL:

Now, how I can return the document's or Pdf's URL when I call this method:

- (void)previewControllerDidDismiss:(QLPreviewController *)controller {
        //here I need to be able to get the PDF's URL or Data when is closed
    }

任何人都可以帮忙吗?

非常感谢.

推荐答案

检查文档此处.还有另一种方法，它可以响应用户的操作并返回所需的URL:

Check documentation here. There is another method, that responds to user actions and returns needed URL:

- (BOOL)previewController:(QLPreviewController *)controller
            shouldOpenURL:(NSURL *)url
           forPreviewItem:(id<QLPreviewItem>)item
