该设备是带有iOS 9.2的iPhone 6s Plus。使用Titanium Studio，当我在调试模式下运行并单步执行代码时，应用程序运行正常。但是，当我只是“运行”它（通过USB连接到笔记本电脑的设备）或在adhoc发行版中安装.ipa文件时，应用程序一启动就会崩溃。 “运行”时，Titanium中绝对没有生成日志。当运行已安装的.ipa时，Xcode中几乎没有相关信息。这是来自Xcode的日志：

我搜索过其他帖子，其中一些人指向“Javascript Minification”（我关闭了但仍然发生了崩溃）以及一些关于代码生成部分中“最快，最小[-Os]”的讨论Xcode的Build设置（我不知道如何控制，因为我正在使用Appcelerator Titanium来构建应用程序）。其他几个人讨论了日志所揭示的特定代码问题。由于我在日志文件中没有得到任何我能说出来的重要信息，我不知道该去哪看。
感谢任何帮助。
2016年3月21日更新：
我花了一段时间才找出罪魁祸首。以下是重现问题的步骤：
1）在Titanium Studio中，使用Alloy Default模板创建一个新的Mobile App项目
2）将新创建的项目按原样运行到USB连接的iPhone 6s Plus（或者可能是任何ios设备）
3）点击设备上的应用程序图标，应用程序将在屏幕上与Hello World一起正常启动
4）现在转到TiApp.xml文件并通过添加以下参数进行编辑：
<property name="appc-sourcecode-encryption-policy">embed</property>
5）现在将修改后的项目运行到USB连接设备
6）打开应用程序，您会发现它在启动画面短暂显示后立即崩溃
看来上面的属性不能正常工作。开设了JIRA门票AC-3389。
