我的应用程序在某种程度上崩溃了UIApplicationMain设备的iOS 10.3.1方法。
到目前为止，这是我记录数据的结果:
0 libobjc.A.dylib 0x00000001943afbd0 objc_msgSend + 12
1 CoreFoundation 0x0000000182b7bf6c ___forwarding___ + 436

13 libdyld.dylib 0x0000000194a1aa08 start + 0
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？
最佳答案
可能是由重命名的IBOutlet实例变量与具有旧名称隐藏在XML中的相应.xib文件之间不匹配引起的？
有关Xcode重构中导致应用程序在执行任何代码之前崩溃的错误的深入示例，请执行以下操作:
