获取属性，方法名列表

iOS代码混淆使用

方法：

- (void)logAllMethodsFromClass:(id)obj
{
    u_int count;
    //class_copyMethodList 获取类的所有方法列表
    Method *mothList_f = class_copyMethodList([obj class],&count) ;
    for (int i = 0; i < count; i++) {
        Method temp_f = mothList_f[i];
        // method_getImplementation  由Method得到IMP函数指针
        IMP imp_f = method_getImplementation(temp_f);
    
        // method_getName由Method得到SEL
        SEL name_f = method_getName(temp_f);
    
        const char * name_s = sel_getName(name_f);
        // method_getNumberOfArguments  由Method得到参数个数
        int arguments = method_getNumberOfArguments(temp_f);
        // method_getTypeEncoding  由Method得到Encoding 类型
        const char * encoding = method_getTypeEncoding(temp_f);
    
        NSLog(@"方法名：%@\n,参数个数：%d\n,编码方式：%@\n",    [NSString stringWithUTF8String:name_s],
          arguments,[NSString stringWithUTF8String:encoding]);
    }
    free(mothList_f);

}

属性

- (NSArray *)getAllProperties:(id)obj
{
    u_int count;

    //使用class_copyPropertyList及property_getName获取类的属性列表及每个属性的名称
    objc_property_t *properties  =class_copyPropertyList([obj class], &count);
    NSMutableArray *propertiesArray = [NSMutableArray arrayWithCapacity:count];
    for (int i = 0; i<count; i++)
    {
        const char* propertyName =property_getName(properties[i]);
        NSLog(@"属性%@\n",[NSString stringWithUTF8String: propertyName]);
        [propertiesArray addObject: [NSString stringWithUTF8String: propertyName]];
    }
    free(properties);
    return propertiesArray;
}

类方法，类方法存放在元组里面

- (NSArray *)getAllClassMethods:(id)obj {
    unsigned int methodCount = 0;
    const char *clsName = class_getName([obj class]);
    Class metaClass = objc_getMetaClass(clsName);
    Method *methodList = class_copyMethodList(metaClass, &methodCount);

    NSMutableArray *arr = [NSMutableArray array];

    for (int i = 0; i < methodCount ; i ++) {
        Method method = methodList[i];
        SEL selector = method_getName(method);
        const char *methodName = sel_getName(selector);
        NSLog(@"%s",methodName);
        NSString *str = [NSString stringWithFormat:@"%s",methodName];
        [arr addObject:str];
    }

    return arr;
}

慢慢来，一步一个巴掌印~~~
