我的应用程序在首次启动时会崩溃,但是在我再次启动时会崩溃。该应用程序很好。

当我按下一个按钮时,它会崩溃,该按钮会播放声音,并允许用户更改所播放歌曲的音高和BPM。

这是日志中的崩溃报告

这是它崩溃的代码
- (OSStatus) readFloatsConsecutive:(SInt64)numFrames intoArray:(float**)audio
{
OSStatus err = noErr;

if (!mExtAFRef) return -1;

int kSegmentSize = (int)(numFrames * mExtAFNumChannels * mExtAFRateRatio + .5);
if (mExtAFRateRatio < 1.) kSegmentSize = (int)(numFrames * mExtAFNumChannels /
mExtAFRateRatio + .5);

AudioBufferList bufList;
UInt32 numPackets = numFrames; // Frames to read
UInt32 samples = numPackets * mExtAFNumChannels;
UInt32 loadedPackets = numPackets;

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;
}

我已经将Xcode说'exc_bad_access'的行加粗了

谢谢

最佳答案

您尝试使用的框架有问题。就我所知,它是内置框架,我认为您的xCode出了点问题。尝试重新安装。
