音乐播放之UISlider

• 1，设置slider的thumbImage
  //设置进度条的滑动块 [self.progressView setThumbImage:[UIImage imageNamed:@"player"] forState:UIControlStateNormal];
• 2，监听拖动至某处松手播放

//Event：touch up inside
(IBAction)dragToSomePoint:(UISlider *)sender {
    self.currentPlayer.currentTime = self.progressView.value*self.currentPlayer.duration;
    self.currentPlayTime.text = [NSString stringWithTimerInterval:curr];

}

• 3，监听点击slider的某处，要先添加UITapGestureRecognize

特别注意：获取位置应该用tap的view，宽度用UISlider的宽度

(IBAction)sliderClicked:(UITapGestureRecognizer *)sender {
    CGPoint point = [sender locationInView:sender.view];
    self.currentPlayer.currentTime = point.x/self.progressView.bounds.size.width*self.currentPlayer.duration;
    self.currentPlayTime.text = [NSString stringWithTimerInterval:self.currentPlayer.currentTime];
}
