在我的项目中,我使用AVAudioPlayer来播放我保存的音频.我正在显示用于播放音频的滑块.使用播放器的当前时间属性设置滑块的值.
playSlider.value = avAudioPlayer.currentTime;
这是计时器代码
updateTimer = [NSTimer scheduledTimerWithTimeInterval:.01 target:self selector:@selector(updateCurrentTime) userInfo:p repeats:YES];
//Calls the update current time function
- (void)updateCurrentTime
{
[self updateCurrentTimeForPlayer:self.player];
}
//Updates the current time while the audio is playing
-(void)updateCurrentTimeForPlayer:(AVAudioPlayer *)avAudioPlayer
{
currentTimeLabel.text = [NSString stringWithFormat:@"%d:%02d", (int)avAudioPlayer.currentTime / 60, (int)avAudioPlayer.currentTime % 60, nil];
playSlider.value = avAudioPlayer.currentTime;
if (playSlider.value==playSlider.minimumValue)
{
moveToBeginningButton.enabled = NO;
rewindButton.enabled = NO;
NSLog(@"PlaySliderMaxValue1 === %f",playSlider.maximumValue);
NSLog(@"PlaySliderValue1 === %f",playSlider.value);
}
else
{
moveToBeginningButton.enabled = YES;
rewindButton.enabled = YES;
NSLog(@"PlaySliderMaxValue2 === %f",playSlider.maximumValue);
NSLog(@"PlaySliderValue2 === %f",playSlider.value);
}
}
滑块的最大值设置如下
playSlider.maximumValue = audioPlayer.duration;
我遇到的问题是,在播放后滑块点将始终返回到音频的开头.这是一个错误吗?我怎么能改变这个?请提供您的建议.
最佳答案 我不能说这是不是一个bug,但尝试使用AVAudioPlayer的委托方法.在didFinishPlaying方法中,将Slider值设置为maximumValue.这可能是解决方案之一.
