找不到iPhone模擬器生成的文件

Question

我很抱歉，如果這與my previous question重複，但這會讓我有點慌亂。

在試圖找出iPhone Simulator存儲文件的位置時，我使用了Speak Here項目來記錄我的聲音並將其保存到文件中。由於模擬器能夠播放記錄，因此必須是某處的文件，但我無法找到該文件。我已經嘗試了一切，包括使用終端命令定位（使用sudo /usr/libexec/locate.updatedb後）。任何幫助？

的#define DOCUMENTS_FOLDER [NSHomeDirectory（）stringByAppendingPathComponent：@ 「文檔」]

- （無效）的StartRecording { [自stopPlaying];

NSLog(@"startRecording"); 
[audioRecorder release]; 
audioRecorder = nil; 

// Init audio with record capability 
AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 
[audioSession setCategory:AVAudioSessionCategoryRecord error:nil]; 

NSMutableDictionary *recordSettings = [[NSMutableDictionary alloc] initWithCapacity:10]; 
if(recordEncoding == ENC_PCM) 
{ 
    [recordSettings setObject:[NSNumber numberWithInt: kAudioFormatLinearPCM] forKey: AVFormatIDKey]; 
    [recordSettings setObject:[NSNumber numberWithFloat:44100.0] forKey: AVSampleRateKey]; 
    [recordSettings setObject:[NSNumber numberWithInt:2] forKey:AVNumberOfChannelsKey]; 
    [recordSettings setObject:[NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey];

    NSNumber *formatObject; 

    switch (recordEncoding) {

      break; 
     default:

    } 

    [recordSettings setObject:formatObject forKey: AVFormatIDKey];

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
// getting an NSInteger 
NSInteger recordID = [prefs integerForKey:@"recordID"]; 
//NSLog(@"---- %d",recordID); 

//NSString *recordFileName = [NSString stringWithFormat:@"%@/record%d.caf", [[NSBundle mainBundle] resourcePath], recordID];

    NSLog(@"Error: %@ [%4.4s])" , [error localizedDescription], (char*)&errorCode); 
} 
NSLog(@"recording"); 

[recordSettings release]; 

}

- （無效）stopRecording { 的NSLog（@ 「stopRecording」）; [audioRecorder stop]; NSLog（@「stopped」）; }

SpeakHere應用程序將錄製的文件存儲在臨時目錄中。你可以找出路徑及其內容與此代碼：

NSString *tempPath = NSTemporaryDirectory(); 
    NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tempPath error:nil]; 
    NSLog(@"tempPath: %@", tempPath); 
    NSLog(@"dirContents: %@", dirContents); 

在iPhone模擬器這條道路會像 /var/folders/eQ/eQdXXQoxFHmxhq85pgNA+++++TI/-Tmp-/，但在設備上，這是在你的應用程序目錄的子目錄。如/private/var/mobile/Applications/965A9EEF-7FBA-40F4-8A42-FE855A719D52/tmp/。
