从MDM安装后，企业应用程序崩溃
我们有一个iOS 9.2应用程序，在通过Xcode和本地Mac安装时运行良好。 当我们通过MDM服务器安装此应用程序时，它会在第一次访问数据时崩溃。 它正在退出，错误是“在10.00s之后无法进行场景更新”。
我从检查控制台输出，它似乎是在requireLogin方法成功过程后挂起（在[self checkIntSession：self.sessionDetail]之后）。
我们使用的是Novell的MDM而不是Apple版本。 我创建了其他已安装并运行没有问题的应用程序。
我尝试过干净的构建和安装。 它没有帮助。 我无法在这里或其他任何地方找到类似的问题。 我不知道接下来要去哪里。 任何帮助，将不胜感激。

===后来添加===
放入完成块并没有解决问题。 完成requireLogin成功部分后，代码似乎仍然挂起。 就像我需要回报或其他东西。
这条线对我来说太可怕了：
while ( self.parseData == NULL );
它可能是调试与发布版本问题。 我可以想象一个发布版本优化了self.parseData的读取，以便不检查其他线程是否已更新它。
我建议您以其他方式执行此操作 – 在这样的循环中进行轮询，在等待时将CPU固定为100％。 我建议将它写成与数据准备就绪时调用的完成块异步。
