StreamingKit seekToTime方法不起作用

Question

这是我的代码。我使用UISlider作为搜索栏，所以当UISlider的值发生变化时，就会调用- (IBAction)sliderValueChanged:(UISlider *)sender。

- (IBAction)sliderValueChanged:(UISlider *)sender
{
[audioplayer seekToTime:_seekbar.value];
}

但是seekToTime方法没有触发。我不明白问题出在哪里。

Answer 1

尝试：

- (IBAction)sliderValueChanged:(UISlider *)sender {

int32_t timeScale = self.audioPlayer.currentItem.asset.duration.timescale;

[self.audioPlayer seekToTime: CMTimeMakeWithSeconds(sender.value, timeScale)
             toleranceBefore: kCMTimeZero
              toleranceAfter: kCMTimeZero
           completionHandler: ^(BOOL finished) {
               [self.audioPlayer play];
           }];
}
