【问题描述】：

我曾经使用UIDocumentInteractionController 和UIActivityViewController 与特殊的UTI 共享数据。

但是，当其他应用使用Share Extension时，弹出分享界面时可能会有copy tp xxx和import to xxx等选项。

我如何禁用这些选项，或者是否有任何其他方式可以将数据共享到我可以控制的指定应用程序。

//======= 我的代码是这样的：

UIActivityViewController *activity = [[UIActivityViewController alloc] initWithActivityItems:@[itemUrl] applicationActivities:nil];
activity.excludedActivityTypes = @[UIActivityTypePostToFacebook, UIActivityTypePostToFacebook,UIActivityTypePostToWeibo,
                                   UIActivityTypeMessage, UIActivityTypeMail, UIActivityTypePrint, UIActivityTypeCopyToPasteboard,
                                   UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr, UIActivityTypePostToFlickr, UIActivityTypePostToFlickr,
                                   UIActivityTypeAirDrop];
[self presentViewController:activity animated:YES completion:NULL];

【参考方案1】：

创建一个数组并添加不想显示给用户的类型，像这样

NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                       UIActivityTypePrint,
                                       UIActivityTypeAssignToContact,
                                       UIActivityTypeSaveToCameraRoll,
                                       UIActivityTypeAddToReadingList,
                                       UIActivityTypePostToFlickr,
                                       UIActivityTypePostToVimeo,
                                       UIActivityTypeCopyToPasteboard];

Create a instance of UIActivityViewController
And set following propery
activityViewController.excludedActivityTypes = excludeActivities

【讨论】：

已经这样做了，它不能阻止那些有Share Extension的应用，它仍然显示copy to xxx和import to xxx

【参考方案2】：

我发现如果您分享为NSURL，您将获得copy to xxx 或import to xxx，但如果您分享为UIImage，您将无法获得。

将显示import to xxx

avc = [[UIActivityViewController alloc] initWithActivityItems:[NSArray arrayWithObjects:fileURL, nil] applicationActivities:nil];
[self presentViewController:avc animated:YES completion:nil];

不会显示

UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:fileURL]];
avc = [[UIActivityViewController alloc] initWithActivityItems:[NSArray arrayWithObjects:image, nil] applicationActivities:nil];
[self presentViewController:avc animated:YES completion:nil];
