编译错误 No matching function for call to 'MSHookMessageEx'

iOS小白

1. static NSString* (*_orig_CTTelephonyNetworkInfo_currentRadioAccessTechnology)(id _self, SEL _cmd1);
   
2. NSString *CTTelephonyNetworkInfo_currentRadioAccessTechnology(id _self, SEL _cmd1){
   
3.    
   
4.     NSLog(@"CTTelephonyNetworkInfo_currentRadioAccessTechnology");
   
5.     return _orig_CTTelephonyNetworkInfo_currentRadioAccessTechnology(_self, _cmd1);
   
6. }
   
7.    
   
8. MSHookMessageEx(objc_getClass("CTTelephonyNetworkInfo"), @selector(currentRadioAccessTechnology), (IMP)CTTelephonyNetworkInfo_currentRadioAccessTechnology, &_orig_CTTelephonyNetworkInfo_currentRadioAccessTechnology);

尝试Hook [CTTelephonyNetworkInfo currentRadioAccessTechnology]，但是上面这个代码编译不了，提示No matching function for call to 'MSHookMessageEx' 这是为什么？

MSHookMessageEx 最后一个参数有点问题，要强制类型转换

1. MSHookMessageEx(objc_getClass("CTTelephonyNetworkInfo"), @selector(currentRadioAccessTechnology), (IMP)CTTelephonyNetworkInfo_currentRadioAccessTechnology, (IMP*)&_orig_CTTelephonyNetworkInfo_currentRadioAccessTechnology);
