String value encountered a warning message, record it
Sending 'const NSString *__strong' to parameter of type 'NSString *' discards qualifiers
The code is written like this
UIKIT_EXTERN const NSString * kNetworkType;
This warning will be issued when using it, and it will be changed to:
UIKIT_EXTERN NSString * const kNetworkType;
If const is placed after nsstring *, there will be no warning.
