UIApplicationMain
我的应用程序在设备方法上以某种方式崩溃iOS 10.3.1
。
它表示SIGSEGV: SEGV_ACCERR崩溃。
到目前为止,这是我记录数据的结果:

这是方法:
// If nil is specified for principalClassName, the value for NSPrincipalClass from the Info.plist is used. If there is no
// NSPrincipalClass key specified, the UIApplication class is used. The delegate class will be instantiated using init.
UIKIT_EXTERN int UIApplicationMain(int argc, char *argv[], NSString * __nullable principalClassName, NSString * __nullable delegateClassName);
关于如何调试这种无效的内存引用错误的任何想法?
