应用程序在Xcode中运行，但在归档时崩溃
我正在归档我的项目，然后使用＆＃34;导出为Mac应用程序＆＃34;选项。当我尝试运行我导出的独立版本时它就崩溃了！似乎有一些与我的音频有关的问题，但我感到困惑，因为当我在Xcode中运行它时它并没有崩溃？有任何想法吗？我的Xcode版本是6.4 btw。这是崩溃日志的第一部分和最后一部分：

-(AVAudioPCMBuffer*) loadSoundIntoBuffer:(NSString *)filename

修改
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。这里也是处理音频的类的代码。

您的某个文件似乎从捆绑包中丢失。
转到＆＃34;构建阶段 - ＆gt;复制捆绑资源＆＃34;并确保所有文件都在那里 - 尤其是使用＆＃34; mp3＆＃34;延期。 还要确保它们具有正确的区分大小写的名称。
