归档，解档的过程中，出现如下的报警信息
'''
[NSKeyedUnarchiver validateAllowedClass:forKey:] allowed unarchiving safe plist type ''NSString' (0x7ff84325e1c8) [/Library/Developer/CoreSimulator/Volumes/iOS_22B81/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 18.1.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Foundation.framework]' for key 'longitude', even though it was not explicitly included in the client allowed classes set: '{(

解决方法
在SKLoginPointModel的.m文件中，将解档的longitude的类型设置一下
，如下
self.longitude = [decoder decodeObjectOfClass:[NSString class] forKey:@"longitude"];
其他的相似的做一下就可以了
