[英]AVAudioPlayer not playing sound from temp file path
我已將錄音保存到我的Temp目錄中 ,可以使用iExplorer進行驗證
文件路徑結構為TempFolder/UserID/SoundName001.wav
。我保存到數據庫的位為UserID/SoundName001.wav
這是我用來播放文件的代碼
@property (nonatomic, strong) AVAudioPlayer *player;
-(void) playSound: (NSIndexPath*)recordingIndex {
NSArray *recording = [recordingArray objectAtIndex:recordingIndex.item-1];
NSString *filePath = [NSString stringWithFormat:@"%@%@",NSTemporaryDirectory(),[recording objectAtIndex:2]];
NSURL *recorderURL = [[NSURL alloc] initFileURLWithPath: filePath];
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:recorderURL error:nil];
[self.player prepareToPlay];
[self.player setMeteringEnabled:YES];
[self.player setDelegate:self];
[self.player play];
}
我設置一個斷點並recorderURL
file:///private/var/mobile/Containers/Data/Application/0883D0DC-B1FD-4D06-A7BB-EBD9EEF5D607/tmp/1/Dog001.wav
返回以下file:///private/var/mobile/Containers/Data/Application/0883D0DC-B1FD-4D06-A7BB-EBD9EEF5D607/tmp/1/Dog001.wav
當我調用此方法時,什么也沒發生,沒有崩潰,沒有聲音……我在這里缺少明顯的東西嗎?
您是否檢查過設備上的靜音開關? 我認為如果打開靜音開關,AVPlayer不會播放聲音。 嘗試放入以下代碼行:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
在您的viewDidLoad
或在[self.player play];
之前[self.player play];
並查看音頻是否播放。
