我已經在我的應用程序中實現了音頻錄製,但我需要知道如何將音頻錄製文件保存在文檔目錄中,並在其他類中檢索用於播放音頻的相同文件。如何將iPhone音頻文件保存在文檔目錄中
這裏是源代碼。
-(void)startPushed
{
NSMutableDictionary *rs = [[NSMutableDictionary alloc] init];
[rs setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
[rs setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[rs setValue:[NSNumber numberWithInt:2] forKey:AVNumberOfChannelsKey];
recordedTmpFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"%.0f.%@", [NSDate timeIntervalSinceReferenceDate] * 1000.0, @"caf"]]];
recorder = [[AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:rs error:&error];
[recorder setDelegate:self];
[recorder prepareToRecord];
[recorder record];
NSArray *docPath = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
NSString *docDir = [docPath objectAtIndex:0];
NSString *fullPath = [docDir stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", recordedTmpFile]];
NSLog(@"%@", fullPath);
}
-(void)playbackPushed
{
AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:recordedTmpFile error:&error];
NSLog(@"Play Path:%@", recordedTmpFile);
[avPlayer prepareToPlay];
[avPlayer play];
}
請告訴我如何讀取和寫入文件目錄 音頻文件(格式的.caf),也給了其他類音頻播放的信息。
在此先感謝
