问题描述
当我为iOS 7构建时，下面的相关代码工作得很好，但现在似乎在iOS 8中，它无法正常工作。
The related code below worked perfect when i was building for iOS 7, but it seems now in iOS 8, it's not working properly.
正确地说，我的意思是在某种意义上，它实际上并没有将文件或其他内容发送到所选择的应用程序。
By properly, I mean in the sense where it's not actually sending the file or whatever to the chosen app.
示例：如果我选择了Mail，它将打开带有图像或zip的邮件应用程序我在文本字段中选择了。现在它不会发送，并且需要永远调用/解除UIDocumentInteractionController。
Example: If I selected Mail, it would open the mail app with the image or zip I chose in the text field. Now it won't send and it takes forever to call/dismiss the UIDocumentInteractionController.
我做错了什么？
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
NSString *fileName = [directoryContents objectAtIndex:indexPath.row];
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Downloads"];
path = [path stringByAppendingPathComponent:fileName];
documentController = [[UIDocumentInteractionController alloc] init];
documentController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]];
[documentController setDelegate:self];
[documentController presentOptionsMenuFromRect:CGRectZero inView:self.view animated:YES];
[documentController retain];
}
推荐答案
我有一直在玩 UIDocumentInteractionController 和Delegate尝试修复类似问题，控制器打开正常但是选择一个应用程序导致它关闭而不做任何事情，我的委托方法 documentInteractionControllerDidDismissOpenInMenu 之后也运行正常。
I have been playing around with the UIDocumentInteractionController and Delegate trying to fix a similar problem, the controller opened-up alright but selecting an application caused it to close without doing anything, my delegate method documentInteractionControllerDidDismissOpenInMenu also run alright afterwards.
在控制台中我收到通知在iOS 8.0中不支持enabledRemoteNotificationTypes后来。
In the console i got the notification enabledRemoteNotificationTypes is not supported in iOS 8.0 and later.
事实证明，当调用其中一个委托方法时，会出现此问题：
It turns out that this problem will accrue when one of these delegate methods is called :
documentInteractionControllerDidDismissOpenInMenu
documentInteractionControllerDidDismissOptionsMenu
（和可能是其他人，我没有检查所有这些）
(and possibly others, i did not check all of them)
我没有在 IOS开发库或 UIDocumentInteractionController.h 关于IOS 8.1不支持的这些方法，但此时我无法找到任何其他解释。
I did not find any comment in the IOS Development Library or the UIDocumentInteractionController.h about these methods not supported for IOS 8.1 but at this point i cant find any other explanation.
我更换了 documentInteractionControllerDidDismissOpenInMenu
与 didEndSendingToApplication
它解决了我的问题。
i replaced documentInteractionControllerDidDismissOpenInMenuwith didEndSendingToApplicationand it solved the problem for me.
