在viewdidload 加载 [self didLoadAudioPlayer];
- (void) didLoadAudioPlayer{
NSString * musicFilePath = @"/Users/Shared/test.mp3"; //创建音乐文件路径
NSURL * musicURL= [[NSURL alloc] initFileURLWithPath:musicFilePath];
AVAudioPlayer * thePlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicURL error:nil]; //创建播放器
self.player = thePlayer; //赋值给自己定义的类变量
[musicURL release];
[thePlayer release];
[player setVolume:1]; //设置音量大小
player.numberOfLoops = -1;//设置音乐播放次数 -1为一直循环
//用NSTimer来监控音频播放进度
timer = [NSTimer scheduledTimerWithTimeInterval:0.1
target:self
selector:@selector(playProgress)
userInfo:nil repeats:YES];
}
//播放进度条
- (void)playProgress {
//通过音频播放时长的百分比,给progressview进行赋值;
musicProcess.progress = player.currentTime/player.duration;
}
//播放完成时调用的方法 需要设置代理才可以调用
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
[timer invalidate]; //NSTimer暂停 invalidate 使...无效;
}
- (IBAction)musicPlay:(id)sender {
[player play];
AudioSessionSetActive(true);
}
- (IBAction)musicStop:(id)sender {
[player pause];
AudioSessionSetActive(false);
}
