應用程序崩潰 - 無法弄清楚爲什麼

-1

我的應用程序在第一次啓動時會崩潰，但是當我再次啓動它時。該應用程序很好。應用程序崩潰 - 無法弄清楚爲什麼

當我按下按鈕時，它會崩潰，按鈕播放聲音並允許用戶更改歌曲播放的音高和BPM。

下面是從日誌崩潰報告

這是它崩潰

    OSStatus err = noErr; 

    if (!mExtAFRef) return -1; 

    int kSegmentSize = (int)(numFrames * mExtAFNumChannels * mExtAFRateRatio + .5);

     goto error; 
    } 

    bufList.mNumberBuffers = 1; 
    bufList.mBuffers[0].mNumberChannels = mExtAFNumChannels; 
    bufList.mBuffers[0].mData = data; // data is a pointer (short*) to our sample buffer 
    bufList.mBuffers[0].mDataByteSize = samples * sizeof(short); 

    // Crash occurs on this line: 
    **err = ExtAudioFileRead(mExtAFRef, &loadedPackets, &bufList);** 
    if (err) goto error; 

    if (audio) { 
     for (long c = 0; c < mExtAFNumChannels; c++) { 
      if (!audio[c]) continue; 
      for (long v = 0; v < numFrames; v++) { 
       if (v < loadedPackets) audio[c][v] = (float)data[v*mExtAFNumChannels+c]/32768.f; 
       else audio[c][v] = 0.f; 
      } 
     } 
    } 

error: 
    free(data); 
    if (err != noErr) return err; 
    if (loadedPackets < numFrames) mExtAFReachedEOF = YES; 
    return loadedPackets; 
}

代碼我做就行了Xcode中說，「部分大膽exc_bad_access'

謝謝

標題在您的問題的標題不是必需的。見http://meta.stackexchange.com/questions/19190/should-questions-include-tags-in-their-titles – 2012-07-31 18:50:02

我再次編輯它，因爲以前的編輯似乎已經損壞了代碼塊。 – Wug 2012-07-31 18:52:16

對不起，感謝您的糾正。 – 2012-07-31 19:00:30

您嘗試使用的框架有問題。在我看到它是內置框架的情況下，我認爲您的xCode存在問題。嘗試重新安裝它。
