ios - 音频直播退到后台出现卡顿

Answer 1

• (void)creatThread
  {
  [NSThread detachNewThreadSelector:@selector(startBackgroundJob:) toTarget:self withObject:nil];
  }
• (void)startBackgroundJob:(id)sender { //开始线程
  [self performSelectorOnMainThread:@selector(updateProgressView:) withObject:nil waitUntilDone:NO];
  } //更新数据
• (void)updateProgressView:(id)sender
  {
  NSString *str = @"http://radio.wlhd.org/hls/live.m3u8";
  NSURL *urlk = [NSURL URLWithString:str];
  [appDelegate.player setContentURL:urlk];
  [appDelegate.player play];

}
我用了一个单线程还是不行
