由于未捕获的异常'NSInvalidArgumentException'而终止应用...原因(键:networkCarrier)

Question

当我运行我的iPad模拟器时,我在应用程序中收到此错误

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: object cannot be nil (key: networkCarrier)'

请帮助我解决这个问题....它将进入主线程

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

Answer 1

添加异常断点.这将导致代码在发生错误的位置停止.转到xcode-> View-> Navigators-> Show Breakpoint Navigator.在左侧窗格中单击"+"并选择"添加异常断点".运行该应用程序.
