AFNetworking 中Assigning to 'AFSSLPinningMode' from incompatible type 'unsigned long _Nullable'

手動導入AFNetworing 出現上邊錯誤

解決方法：

1）AFSecurityPolicy.m

self.SSLPinningMode =  [[decoder decodeObjectOfClass:[NSNumber class] forKey:NSStringFromSelector(@selector(SSLPinningMode))] unsignedIntegerValue];
改為
self.SSLPinningMode = (AFSSLPinningMode)  [[decoder decodeObjectOfClass:[NSNumber class] forKey:NSStringFromSelector(@selector(SSLPinningMode))] unsignedIntegerValue];
           

2）AFNetworkReachability.m

_networkReachability = CFRetain(reachability);

 改為

 _networkReachability = (SCNetworkReachabilityRef)CFRetain(reachability);


           

3）添加依賴庫，去除其他錯誤

Security.framework
MobileCoreServices.framework
SystemConfiguration.framework
           

問題：

為啥我建立工程，就沒有出現上邊錯誤呢？
