This question already has an answer here:

这个问题已经有了答案:

Get the json which is in NSData 1 answer
得到NSData 1中的json。

So I'm using an HTTP GET method which returns an array of JSON objects, which are stored in NSData. The array looks like this:

我使用的是HTTP GET方法，它返回一个JSON对象数组，这些对象存储在NSData中。数组如下所示:

[{"created_at":"2013-03-09T04:55:21Z","data_type":"image","id":5354,"latitude":37.785834,"longitude":-122.406417,"name":"tempObject","privacy":"public","radius":1000.0,"updated_at":"2013-03-09T04:55:21Z","user_id":101},{"created_at":"2013-03-10T20:57:08Z","data_type":"image","id":5364,"latitude":37.785834,"longitude":-122.406417,"name":"tempObject","privacy":"public","radius":1000.0,"updated_at":"2013-03-10T20:57:08Z","user_id":101}]

How would I go about extracting these JSON objects and iterate through them from the NSData?

如果你正在使用iOS 5.0或以上版本，你可以这样做:

Objective-C

objective - c

NSError *error = nil;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:myNSData options:kNilOptions error:&error];

if (error != nil) {
    NSLog(@"Error parsing JSON.");
}
else {
    NSLog(@"Array: %@", jsonArray);
}

Swift 2.1

斯威夫特2.1

do {
    let jsonArray = try NSJSONSerialization.JSONObjectWithData(myNSData, options:[])
    print("Array: \(jsonArray)")
}
catch {
    print("Error: \(error)")
}
