将JSON解码为NSArray或NSDictionary

问题描述：

我希望对下面的JSON数据进行解码:

I hope to decode the JSON data below:

{
    "content":
    [   
        {
            "1":"a",
            "2":"b",
            "3":"c",
            "4":"d",
            "mark":"yes"
        }
    ]
}

不确定是否将其放入NSArray或NSDictionary

Not sure if put it in NSArray or NSDictionary

您使用的是哪个iOS版本?在iOS 5中，您具有NSJSONSerialization类来解析JSON数据，如果您需要定位较旧的iOS或MAC OSX，则应使用第三方库，例如SBJSON.发布的字符串将是NSDictionary，其中包含一个带有一个字典的数组.使用键@"content"

which iOS version are you using? in iOS 5 you have the NSJSONSerialization class to parse JSON data, if you need to target older iOSs or MAC OSX you should use third parties lib such as SBJSON. The string posted will be a NSDictionary with an array with one dictionary. The array will be accessible using the key @"content"

在代码中:

NSString * jsonString = @"blblblblblb";
NSStringEncoding  encoding;
NSData * jsonData = [jsonString dataUsingEncoding:encoding];
NSError * error=nil;
NSDictionary * parsedData = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];

在SWIFT 2.0中:

In SWIFT 2.0:

    let jsonString = "blblblblblb"
    let encoding = NSUTF8StringEncoding
    let jsonData = jsonString.dataUsingEncoding(encoding)
    guard let jData = jsonData else {return}
    do {
        let parsedData = try NSJSONSerialization.JSONObjectWithData(jData, options: [])
    } catch let error {
        print("json error: \(error)")
    }

[更新] NSJSONSerialization类也可用于10.7我的评论不正确.

[UPDATE] The NSJSONSerialization class is also available for 10.7 my comment wasn't correct.
