问题描述

我的UIDocumentsInteractionController工作到提出一个动作表与一个按钮,说iBooks,但当我点击该按钮,它只是消除,它不会把我带到iBooks。这是我的代码:

My UIDocumentsInteractionController is working as far as presenting an action sheet with a button that says "iBooks" but when I click on that button, it just dismisses and it doesn't take me to iBooks. Here's my code:

NSString *filenamePath =[NSString stringWithFormat:@"temp.%@", [[file path] pathExtension]];

    NSString *docDir = [DataCenter getDocumentsDirectoryPath];

    NSString *fullPath = [docDir stringByAppendingPathComponent:filenamePath];

    NSURL *url = [NSURL fileURLWithPath:fullPath];
    UIDocumentInteractionController *c = [UIDocumentInteractionController interactionControllerWithURL:url];

    BOOL success = [c presentOpenInMenuFromBarButtonItem:buttonBack animated:YES];

我做错了什么?
感谢

What am I doing wrong?Thanks

推荐答案

对于那些困扰你的人:你不需要将自己设置为UIDocumentInteractionController的委托。

For those stuck at this: You don't need to set yourself up as UIDocumentInteractionController's delegate at all.

问题是 [UIDocumentInteractionControllerinteractionControllerWithURL:url] 正在自动释放。它认为它将被显示的操作表内部保留,但显然不是。
所以,要保留它,直到行动表驳回。

Problem was [UIDocumentInteractionController interactionControllerWithURL:url] is being autoreleased. It thought it would be retained internally by the action sheet being shown but apparently it's not.So yea, gotta retain it until action sheet dismisses.
