应用程序在 Xcode 中运行，但存档时崩溃

【中文标题】应用程序在 Xcode 中运行，但存档时崩溃【英文标题】：App runs in Xcode, but crashes when archived 【发布时间】：2015-08-20 19:33:27 【问题描述】：我正在归档我的项目，然后使用“导出为 Mac 应用程序”选项。当我尝试运行我导出的独立版本时，它会崩溃！似乎与我的音频有关的一些问题，但我很困惑，因为当我在 Xcode 中运行它时它不会崩溃？有任何想法吗？我的 Xcode 版本是 6.4 顺便说一句。这是崩溃日志的第一部分和最后一部分：

编辑：导致错误的代码
-(AVAudioPCMBuffer*) loadSoundIntoBuffer:(NSString *)filename
// load the collision sound into a buffer
NSURL *soundFileURL = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:filename ofType:@"mp3"]];
NSAssert(soundFileURL, @"Error creating URL to sound file");
NSError *error;
AVAudioFile *soundFile = [[AVAudioFile alloc] initForReading:soundFileURL commonFormat:AVAudioPCMFormatFloat32 interleaved:NO error:&error];
NSAssert(soundFile != nil, @"Error creating soundFile, %@", error.localizedDescription);

NSAssert([soundFile readIntoBuffer:outputBuffer error:&error], @"Error reading file into buffer, %@", error.localizedDescription);
return outputBuffer;
编辑： 我用 aiff 文件替换了我的 mp3 文件，最初的问题已经改变。该应用程序仍然在 Xcode 之外崩溃，但不再在主线程上崩溃，如下所示。这与音频有关。下面是处理音频的类的代码。

新的崩溃日志
【问题讨论】：
发布目标中可能缺少一个文件。您是否使用多个目标？另请附上处理此文件打开的代码：[AVAudioFile initForReading] 我的部署目标是 OS X 10.10，所以不，我只有一个目标。我已将代码附加到问题的底部。 您附加了调试信息，而不是代码本身。您的 fileURL 似乎在某个地方为零。显示代码如何为音频文件生成路径 我在写完评论后附上了它。我没想到你会这么快检查！ 【参考方案1】：捆绑包中似乎缺少您的一个文件。
转到“构建阶段 -> 复制捆绑资源”并确保所有文件都在那里 - 特别是带有“mp3”扩展名的文件。 还要确保它们有正确的区分大小写的名称。
【讨论】：
是的，在您发表评论后，我又检查了几个小时。我正在从 plist 文件中读取名称。据我所知，所有的名字都匹配。 17 个 .mp3 文件中有 17 个都包含在“复制捆绑资源”部分中。我正在阅读有关更改运行方案的信息，以便它使用Release 构建配置运行，当我这样运行它时它会崩溃。显然，这会导致它以与存档时相同的方式运行。调试器只显示汇编代码，对我来说没用。
我 100% 确定的一件事是我的班级 AudioEngine（这是一个单例）管理音频文件的播放，这是问题所在。我刚刚再次完成了我的项目的归档，并且在加载的第一个场景中删除了对 AudioEngine 的调用，并且应用程序完美运行。即使我将加载限制为仅几个 mp3 文件，它也会崩溃，所以这让我相信我从磁盘加载文件的方式是错误的。它在 Xcode 中工作！这太令人困惑了:(
我决定用 aiff 文件替换我的 mp3 文件。崩溃发生在与以前不同的线程上。我认为错误是格式。它是线程 13 而不是主线程。
我想我找到了问题所在。根据 WWDC 2014 会话 501，演讲者（在 54:17）将音频文件分块读入缓冲区，并使缓冲区帧容量为 128 * 1024L。一旦我将代码转换为以较小的块将文件读入缓冲区，我就不会再崩溃了，但是我遇到了一个新问题，即文件不是从头开始播放，而是从缓冲区最后一帧的开头开始播放。 【参考方案2】：
崩溃的原因是我正在读入AVAudioPCMBuffer 的音乐文件太大。我的解决方案是限制缓冲区的大小，并根据音频文件的帧数使用多个缓冲区。解决方法可以看here
