我有一些适用于iOS 7的共享代码,但从iOS 8开始,不再有效。
@IBAction func onShareButton(sender: UIButton) {
let movie = NSBundle.mainBundle().URLForResource("IMG_0564", withExtension: "mp4")!
let items = [movie]
let activity = UIActivityViewController(activityItems: items, applicationActivities: nil)
if activity.respondsToSelector("popoverPresentationController") {
activity.popoverPresentationController?.sourceView = sender
}
self.presentViewController(activity, animated: true, completion: nil)
}
正如我所说,这在iOS 7中运行良好,但是从iOS 8开始,当我选择分享到Facebook时,视频剪辑不再附加到帖子(或在共享面板中可见)。所有其他选项,Mail,Save to Video,AirDrop等都可以正常工作。
我还尝试将这些项目作为AVAssets传递:
let items = [movie].map { AVAsset.assetWithURL($0) }
和NSData:
let items = [movie].map { NSData(contentsOfURL: $0) }
这两项都没有对这个问题产生任何影响。
如果我在Objective-C中使用道德等价物,那么问题也会发生,它与语言无关。

我遇到了同样的问题,我发现关键点是文件类型。我试图分享.mp4视频,它不会将视频附加到帖子中。一旦我使用.mov视频,它对我有用。

好的,我尝试了一种解决方法,它对我有用。
我首先将视频数据保存到文档目录中的文件中,然后附加了该文件。
//write to a file
[videoData writeToFile:[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/image.mov"] atomically:YES];
- (IBAction)ShareVideoWihFacebook:(id)sender
{
//get the file url
NSString* path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/image.mov"];
NSURL *videoURL = [NSURL fileURLWithPath:path];
UIActivityViewController * activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[videoURL,@"Created by ..."] applicationActivities:NULL];
[activityVC setExcludedActivityTypes:@[ UIActivityTypeMail,UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypePrint, UIActivityTypePostToWeibo,UIActivityTypeMessage,UIActivityTypeAirDrop,UIActivityTypeSaveToCameraRoll]];
[activityVC setValue:@"My Video" forKey:@"subject"];
[activityVC setCompletionHandler:^(NSString *activityType, BOOL completed) {
//NSLog(@"completed dialog - activity: %@ - finished flag: %d", activityType, completed);
}];
[self presentViewController:activityVC animated:TRUE completion:nil];
}
