MJExtension 解析嵌套model

MJ 的使用

直接上代码吧

NewsViewController.m 文件

- (void)viewDidLoad  {
    [super viewDidLoad];
    self.navigationItem.title = @"新闻";
    
    [self test_mj];
}

- (void)test_mj {

    // 自定义的json数据
    NSDictionary *dict = @{
                           @"resut":@{
                                   @"name":@"terry",
                                   @"age":@"21",
                                   @"info":@[
                                           @{@"a1":@"a1",@"a2":@"a2",@"my":@{@"n1":@"n1",@"n2":@[@{@"m1":@"m1",@"m2":@"m21"}]}},

                                           @{@"a1":@"c1",@"a2":@"c2",@"my":@{@"n1":@"n3",@"n2":@[@{@"m1":@"m3",@"m2":@"m23"}]}},
                                           ],
                                   },
                           @"code":@"1",
                           @"msg":@"",
                           };

    TestModel *model = [TestModel mj_objectWithKeyValues:dict[@"resut"]];
    for (infoModel *infoModel in model.info) {
        
        NSLog(@"info-a1 %@",infoModel.a1);
        NSLog(@"info-my-n1 %@",infoModel.my.n1);
        
        for (n2Model *n2Model in infoModel.my.n2) {
            
            NSLog(@"info-my-n2-m1 %@",n2Model.m1);
        }
    }
}
