Question

我从目标C的关键值得到了价值，但是在swift中我不知道怎么做？

 NSDictionary *dictResult = [NSJSONSerialization
                                JSONObjectWithData:jsonData options:0 error:&error];

if ([dictResult objectForKey:@"wsResponse"]!=nil)
{
     for (NSDictionary *dict in [[dictResult valueForKey:@"wsResponse"]valueForKey:@"Bhaktamar"])
     {
            objBean=[[Beandata alloc]init];
            objBean.strcontent=[dict objectForKey:@"content"];
            objBean.strtitle=[dict objectForKey:@"title"];

            [dataBase insertJsonData:@"BhaktamarData" Title:objBean.strtitle Content:objBean.strcontent];

     }
}

先谢谢

JSON ARRAY

{"wsResponse":{"Bhaktamar":[{"content":"atipati nath","title":"atipatinath"},{"content":"atipati nath","title":"atipatinath"}]}

Swift 3的等价物是：

do {
    if let dictResult = try JSONSerialization.jsonObject(with:jsonData, options:[]) as? [String:Any] {
        if let wsResponse = dictResult["wsResponse"] as? [String:Any], let shlock = wsResponse["Bhaktamar"] as? [[String:Any]] {
            for dict in shlock {
                objBean = Beandata()
                objBean.strcontent = dict["content"] as? String ?? ""
                objBean.strtitle = dict["title"] as? String ?? ""
                dataBase.insertJsonData("BhaktamarData", Title:objBean.strtitle, Content:objBean.strcontent)
            }
        }
    }
} catch {
    print(error)
}

插入行的语法可能不同（第一个参数必须有参数标签）。

PS：考虑变量objBean在重复循环中初始化但实际上未使用。
