在SWIFT中解析Google Calendar JSON

Question

var url : String = "some url"
var request : NSMutableURLRequest = NSMutableURLRequest()
request.URL = NSURL(string: url)
request.HTTPMethod = "GET"

NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue(), completionHandler:{ (response:NSURLResponse!, data: NSData!, error: NSError!) -> Void in
    var error: AutoreleasingUnsafeMutablePointer<NSError?> = nil
    let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary

    if (jsonResult != nil){
      // No idea how to parse this object as it seems to be a NSDictionary but battling to interact with it.
    }
    else 
    {

    }
})

如有任何帮助，将不胜感激。

如果在后面加上断点

let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary

然后您就可以看到字典键/值对了。我复制/粘贴了您的代码，并看到以下内容：

您可以使用jsonResult.objectforKey（“keyName”）访问这些值。我还将使用作为datatype向下转换。

let encoding = jsonResult.objectForKey("encoding") as String
let version = jsonResult.objectForKey("version") as String
let feed = jsonResult.objectForKey("feed") as NSDictionary
