我这里需要判断手机号码，qq号码，邮箱等的规范，所以需要用到正则表达式，导入RegexKitLite.h之后就出现了警告

        id
        functionString = [exception objectForKey:@
        "function"
        ], fileString = [exception objectForKey:@
        "file"
        ], descriptionString = [exception objectForKey:@
        "description"
        ], lineNumber = [exception objectForKey:@
        "line"
        ];
       
 
              
        RKLCHardAbortAssert((functionString != 
        NULL
        ) && (fileString != 
        NULL
        ) && (descriptionString != 
        NULL
        ) && (lineNumber != 
        NULL
        ));
       
 
              
        [[
        NSAssertionHandler
        currentHandler] handleFailureInFunction:functionString file:fileString lineNumber:(
        NSInteger
        )[lineNumber longValue] description:descriptionString];
       

这就是出现警告的地方， Format string is not a string literal (potentially insecure)
这里该怎么修改才可以去掉警告呢

description:descriptionString,nil];

还有个地方说这样改:

;

 [[NSAssertionHandler currentHandler] handleFailureInFunction:functionString file:fileString lineNumber:(NSInteger)[lineNumber longValue] description:descriptionString];

A : [[ NSAssertionHandler currentHandler ] handleFailureInFunction :functionString file :fileString lineNumber :( NSInteger )[lineNumber longValue ] description : @"%@" ,descriptionString];
