Ios 如何修复可以在swift中将[NSDictionary]转换为NSDictionary的错误？

我试图在tableviewcells上显示我的json数据。但是，我在将json结果添加到我的配置文件homemodel时遇到了问题。我的请求管理器中出现错误，该错误表示无法将[NSDictionary]转换为NSDictionary

以及

NSData（contentsOfURL:）

检索的数据示例：

---

您正在尝试将数组（

[NSDictionary]

）转换为单个

NSDictionary

，这是不允许的。访问您必须访问的阵列以获取您要查找的阵列

比如说

let myProfile = profile.firstObject

---

它是

NSDictionary

而不是

[NSDictionary]

let profile = jsonData!.objectForKey("profile") as? NSDictionary

您的代码还存在其他问题，如以下问题，这些问题没有意义，可能会导致错误

for profile in profile {
    print(profile)
}

---

一个有效的json字符串可以由数组或字典定义。如果您不知道json字符串的格式，那么应该在操作其内容之前检查其类型

do {
    if let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? NSDictionary {
        //got a dictionary, do your works with this dictionary
    } else if let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? NSArray {
        //got an array, do your works with this dictionary
    } else {
        //is not a valid json data
    }
} catch let _error as NSError {
   //got error
}

---

在我看来，对象被序列化为一个直接的字典，而不是一个字典数组。您能否发布通过NSData（contentsOfURL:）检索的相关数据片段？我以json格式发布了我试图检索的数据。您的数据片段非常清楚地显示了您的问题：

profile

是一本字典。您正试图将其转换为一系列词典。将您的演员阵容从

[NSDictionary]

更改为

NSDictionary

我按照您提到的方式进行了更改。它给了我一个错误，说profilehomemodel没有成员类型appendI，我做了您提到的更改。它给了我一个错误，说profilehomemodel没有成员类型append@VigneshKrish你的代码有几个问题，我很抱歉不能为你解决所有问题。提示：JSON节点永远不会是

[NSDictionary]

，您可能不想使用for循环访问

NSDictionary

。
