我使用AVAudioplayer通過按下一個按鈕,使用這下面的代碼打3名型動物的歌曲:AVAudioPlayer量CONTROLE
-(IBAction)play
{
//Play sound1
NSString *pathToMusicFile1 = [[NSBundle mainBundle] pathForResource:@"Sample1" ofType:@"mp3"];
AVAudioPlayer* mySong1 = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:pathToMusicFile1] error:NULL];
NSLog(@"Song1 Loaded");
mySong1.numberOfLoops = 0;
mySong1.volume = 1.0;
[mySong1 play];
//Play sound2
NSString *pathToMusicFile2 = [[NSBundle mainBundle] pathForResource:@"Sample2" ofType:@"mp3"];
AVAudioPlayer* mySong2 = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:pathToMusicFile2] error:NULL];
NSLog(@"song2 Loaded");
mySong2.numberOfLoops = 0;
mySong2.volume = 1.0;
[mySong2 play];
//Play sound3
NSString *pathToMusicFile3 = [[NSBundle mainBundle] pathForResource:@"Sample3" ofType:@"mp3"];
AVAudioPlayer* mySong3 = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:pathToMusicFile3] error:NULL];
NSLog(@"song3 Loaded");
mySong3.numberOfLoops = 0;
mySong3.volume = 1.0;
[mySong3 play];
}
這工作得很好,但現在我想用3個按鍵靜音關閉Sound1例子,SOUND2和聲音3. 我試過:
-(IBAction)sound1
{
mySong1.volume = 0.0;
}
-(IBAction)sound2
{
mySong2.volume = 0.0;
}
-(IBAction)sound3
{
mySong3.volume = 0.0;
}
但我得到的錯誤 「mySong1未申報」!我怎樣才能設法聲明並有可能通過按下按鈕來關閉其中一個聲音?
