Could not successfully update network info during initialization

Could not successfully update network info during initialization 并且一跑程序就崩溃

在personalInfo 单例实例化时，内部最好不要调用AFN请求，会崩溃，提示 "Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)" 在外面初始化单例之后调用 方法，或者 performSelector after 延迟一秒后执行。
