是否有可能从一个URL链接使用网页预览框架

Question

正如标题所说，我只需要通过使用URL链接，显示存储在远程服务器中的PDF文件，而无需下载在设备上查看PDF文件。是否可以通过使用Quick Look框架来实现？

我使用下面这段代码：

- (void)openDocument { 
    QLPreviewController *docPreviewController = [[QLPreviewController alloc] init]; 
    [docPreviewController setDataSource:self]; 
    [docPreviewController setDelegate:self]; 
    [docPreviewController setCurrentPreviewItemIndex:sender.tag]; 
    [self.destinationViewController presentViewController:docPreviewController animated:true completion:nil]; 
} 

- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller { 
    return 1; 
} 

- (id<QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index { 
    return [NSURL fileURLWithPath:@"http://www.domain.com/file.pdf"]; 
} 

但我在控制台这个问题：

UIDocumentInteractionController: invalid scheme https. Only the file scheme is supported. 

Answer 1

我以UIDocumentInteractionController

UIDocumentInteractionController *viewer = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]]; 
viewer.delegate = self; 
[viewer presentPreviewAnimated:YES];
