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:

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?

IBOutlet可能是由于重命名的实例变量与 XML 中埋有旧名称的相应 .xib 文件之间的不匹配造成的?

UIApplicationMain()有关 Xcode 重构中导致应用程序在执行任何代码之前崩溃的缺陷的深入示例:

IBOutlet 名称更改导致 UIApplicationMain 崩溃
