    If you want to check any NSString containing special characters then check this out.

    -(BOOL)specialCharacter:(NSString*)username{
        NSCharacterSet *invalidCharSet = [[NSCharacterSet characterSetWithCharactersInString:@"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"] invertedSet];
        NSString *filtered = [[username componentsSeparatedByCharactersInSet:invalidCharSet] componentsJoinedByString:@""];
        return ![username isEqualToString:filtered];
    
    }
    
    

    Hope this will help you.

    Happy Coding!!!
