0x01直接上代码

    NSDictionary *dic = @{@"views":@[@{@"tag":@"100"},@{@"tag":@"200"}]};
    for (NSDictionary *subDic in dic) {
        NSString *key = [NSString stringWithFormat:@"%@",subDic[@"tag"]];
        NSLog(@"key:%@",key);
    }

​​subDic​​​ 控制台输出的内容是：​​views​​.

0x02结论

1.要遍历是应该是​​views​​​对应的value(数组)。
2.对一个字典进行遍历时，取到的是key。
