在使用AudioStreamer中的下一个和上一个function时，两个或更多个歌曲将一起启动

这是下一个和上一个button的代码

- (IBAction)nextPressed:(id)sender { Previousbutton.enabled=YES; Nextbutton.enabled = NO; NSLog(@"TOTAL TRACK:%d",TotalTrackCount); // TrackCount = TotalTrackCount+1; if(selectedIndex+1 < TotalTrackCount) { [streamer stop]; [self performSelector:@selector(destroyStreamer) ] ; //player flag player=@"stop"; int new_index; new_index=selectedIndex+1; selectedIndex=new_index; str_AudioUrl=[array_audioUrl objectAtIndex:selectedIndex]; userPrefs = [NSUserDefaults standardUserDefaults]; [userPrefs setInteger:new_index forKey:@"Index"]; str_AudioUrl=[array_audioUrl objectAtIndex:new_index]; [self performSelector:@selector(createStreamer) ] ; //[self setButtonImage:[UIImage imageNamed:@"loadingbutton.png"]]; [streamer start]; NSString *newtitle=[array_AudioName objectAtIndex:new_index]; self.title=newtitle; NSLog(@"selected index next==%d",selectedIndex); [self performSelector:@selector(enableNext) withObject:nil afterDelay:2.0]; } else { Nextbutton.enabled=NO; } } - (void) enableNext { Nextbutton.enabled = YES; } //it will play next sone from table (next index) - (IBAction)previousPressed:(id)sender { Nextbutton.enabled = YES; Previousbutton.enabled = NO; NSLog(@"selected index previous==%d",selectedIndex); if(selectedIndex >0) { [streamer stop]; //player flag player=@"stop"; [self performSelector:@selector(destroyStreamer) ] ; int new_index; new_index=selectedIndex-1; selectedIndex=new_index; str_AudioUrl=[array_audioUrl objectAtIndex:selectedIndex]; userPrefs = [NSUserDefaults standardUserDefaults]; [userPrefs setInteger:new_index forKey:@"Index"]; str_AudioUrl=[array_audioUrl objectAtIndex:new_index]; [self performSelector:@selector(createStreamer)] ; [self setButtonImage:[UIImage imageNamed:@"loadingbutton.png"]]; [streamer start]; NSLog(@"selected index previous2==%d",selectedIndex); NSString *newtitle=[array_AudioName objectAtIndex:new_index]; self.title=newtitle; [self performSelector:@selector(enablePrevious) withObject:nil afterDelay:2.0]; } else { Previousbutton.enabled = NO; } } - (void) enablePrevious { Previousbutton.enabled = YES; }

AudioStreamer类在stream式传输过程中有一个与暂停相关的错误。 所以gitHub给出了一个很好的post来解决这个问题。
