这样子有个问题：

 Ivar ivar = class_getInstanceVariable([self class], [dicName UTF8String]);  //字典对象

获取不到Category中的属性

- (void)setModels
{

    NSArray *keys = [self getProperties];
    //(2)根据类型给属性赋值
    for (NSString * key in keys) {
        NSMutableString *_iOTName =  [[NSMutableString alloc]initWithString:[self addLineToName:key]];
        [_iOTName replaceCharactersInRange:NSMakeRange(, ) withString:@"_iOT"]; //_iOTXXX

        [_iOTName deleteCharactersInRange:NSMakeRange(, )]; //iOTName

        SEL iotGetSEL = NSSelectorFromString(_iOTName);
         if ([CURRENT_ACTIVE_ROBOT respondsToSelector:iotGetSEL]) { //存在对应的iOT对象
              Ivar ivar = class_getInstanceVariable([self class], [[self addLineToName:key] UTF8String]);  //字典对象
              NSDictionary *tempDic = object_getIvar(self, ivar);
             if(tempDic){
                 NSString *jsonStr = tempDic[@"value"];
                 NSDictionary *modelDict =  [self dictionaryWithJsonString:jsonStr];
                 NSMutableString *modelName =  [[NSMutableString alloc]initWithString:[self upperPropertyName:_iOTName]];
                 Class modelClass = NSClassFromString(modelName);
                 id tempObj = [modelClass mj_objectWithKeyValues:modelDict];
                 [CURRENT_ACTIVE_ROBOT setValue:tempObj forKey:_iOTName];
                 NSLog(@"EcoAllRobot:%ld,%ld",CURRENT_ACTIVE_ROBOT.iOTSpeed.speed,CURRENT_ACTIVE_ROBOT.iOTBreakPoint.enable);
                 NSLog(@"tempDic::%@,modelDict:%@,iOTName:%@,modelName:%@", tempDic,modelDict,_iOTName,modelName);
