objective-c - MPMoviePlayerViewController 无法设置当前播放时间

Question

我正在尝试在 MPMoviePlayerViewController 中设置 MPMoviePlayerController 的 currentPlaybackTime 属性，以使其从那时起恢复播放视频(HLS 流)，当应用程序退出事件时它已停止。这是我的代码:

    //the functinon that sets playback time
    - (void)setCurrentPlayTime:(NSNumber *)time {
        if (self.moviePlayer.currentPlaybackTime < [time floatValue] - 10.0) {
            [self.moviePlayer setCurrentPlaybackTime:(NSTimeInterval)[time floatValue]];
        }
    }

    //app did become active callback
    - (void) applicationDidBecomeActiveNotification:(NSNotification*)notification {
        if (!isnan(_curPlayTime) && _curPlayTime > 0.0) {
            [self performSelector:@selector(setCurrentPlayTime:) withObject:[NSNumber numberWithFloat:_curPlayTime] afterDelay:0.1];
        }
    }

    //player load state did change callback
    -(void)playerLoadStateDidChange:(NSNotification *)notification {   
    MPMoviePlayerController *player = notification.object;
    MPMovieLoadState loadState = player.loadState;  
if (loadState & MPMovieLoadStatePlaythroughOK) {
        if (!isnan(_curPlayTime) && _curPlayTime > 0.0) {
            [self performSelector:@selector(setCurrentPlayTime:) withObject:[NSNumber numberWithFloat:_curPlayTime] afterDelay:0.1];
            _curPlayTime = 0.0;
        }
}

当我只需点击主页按钮然后重新打开应用程序时，如果我接到来电但拒接，它也能正常工作。但是如果我接听来电，在我结束通话后，播放从 0.0 开始，忽略 setCurrentPlaybackTime 方法调用。有谁知道，问题出在哪里，可能是应该如何正确工作的任何例子？

不确定这是否是问题所在，但您搜索的选择器是 setCurrentPlayTime 而不是 setCurrentPlay*back*Time。
