Iphone 如何从MPMoviePlayerController获取播放%进度

我想知道当用户关闭视频时，视频已经进展了多远

因此，我有这个：

- (void) moviePlayerDidFinsh:(NSNotification*) notification
{
    MPMoviePlayerController* moviePlayer = notification.object;
    NSLog(@"FINISHED duration was:%f", moviePlayer.duration);
}

initialPlaybackTime

和

endPlaybackTime

这两个seam都是无用的。

属性是

currentPlaybackTime

（以秒为单位）

只有当

MPMovieFinishReason

等于

mpmoviefinishreasonusexited

时，这才有用

NSDictionary* userInfo = [aNotification userInfo];    
MPMovieFinishReason finishReason = [[userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue];
if (finishReason == MPMovieFinishReasonUserExited) {
        NSTimeInterval playbackTime = [moviePlayer currentPlaybackTime];
        // ...
}

MPMediaPlayback协议中有一个属性

currentPlaybackTime

播放头的当前位置。（必选）

@属性（非原子）NSTimeInterval currentPlaybackTime

---

%值=当前播放时间/持续时间

不，不是。我试过“mpmoviefinishreasonlaybackend”。它也有用。不，不是。我试过“mpmoviefinishreasonlaybackend”。它也起作用。
