 When I try to click the menu action button in QLPreviewController the application crashes.

这就是我在委托方法中所做的

- (id)previewController:(QLPreviewController *)previewController previewItemAtIndex:(NSInteger)index
{

    NSMutableString*Url = [[NSMutableString alloc] initWithFormat:@"http://10.30.24.21/Documents/abc.doc];

    NSURL *fileURL;
    fileURL = [NSURL URLWithString:Url];// the url of the file which is present in NAS device
    [Url release];
    return fileURL;
}

这是崩溃报告

DropBox应用程序允许您通过选择该Open In选项在另一个应用程序中查看文档.

我们正在构建一个文档管理应用程序,并且需要能够在另一个应用程序中查看Dropbox的Word/Excel文档.

我在SDK中的哪个位置,以便我可以将文档传递给另一个应用程序以在该应用程序中打开？
