这是我的方法:
-(void) playOrRecord:(UIButton *)sender {
if (playBool == YES) {
NSError *error = nil;
NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:&error];
[player setNumberOfLoops:0];
[player play];
}
else if (playBool == NO) {
if ([recorder isRecording]) {
[recorder stop];
[nowRecording setImage:[UIImage imageNamed:@"NormalNormal.png"] forState:UIControlStateNormal];
[nowRecording setImage:[UIImage imageNamed:@"NormalSelected.png"] forState:UIControlStateSelected];
}
if (nowRecording == sender) {
nowRecording = nil;
return;
}
nowRecording = sender;
NSError *error = nil;
NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
[sender setImage:[UIImage imageNamed:@"RecordingNormal.png"] forState:UIControlStateNormal];
[sender setImage:[UIImage imageNamed:@"RecordingSelected.png"] forState:UIControlStateSelected];
recorder = [[AVAudioRecorder alloc] initWithURL:fileUrl settings:recordSettings error:&error];
[recorder record];
}
}
其中大部分是不言自明的;playBool 是一个 BOOL,在播放模式下为 YES。一切都在模拟器中运行,但是,当我在设备上运行它时,[记录器记录]返回 NO。有没有人知道为什么会这样?
