应用程序崩溃 - 无法弄清楚为什么

-1

我的应用程序在第一次启动时会崩溃，但是当我再次启动它时。该应用程序很好。应用程序崩溃 - 无法弄清楚为什么

当我按下按钮时，它会崩溃，按钮播放声音并允许用户更改歌曲播放的音高和BPM。

下面是从日志崩溃报告

这是它崩溃

- (OSStatus) readFloatsConsecutive:(SInt64)numFrames intoArray:(float**)audio

    OSStatus err = noErr; 

    if (!mExtAFRef) return -1; 

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

    short *data = (short*)malloc(kSegmentSize*sizeof(short)); 
    if (!data) { 
     NSLog(@"data is nil"); 
     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; 
}

代码我做就行了Xcode中说，“部分大胆exc_bad_access'

谢谢

标题在您的问题的标题不是必需的。见http://meta.stackexchange.com/questions/19190/should-questions-include-tags-in-their-titles – 2012-07-31 18:50:02

我再次编辑它，因为以前的编辑似乎已经损坏了代码块。 – Wug 2012-07-31 18:52:16

对不起，感谢您的纠正。 – 2012-07-31 19:00:30

您尝试使用的框架有问题。在我看到它是内置框架的情况下，我认为您的xCode存在问题。尝试重新安装它。
