Using a Javascript API for iOS development

Question

So basically I'm trying to learn more about iOS development and APIs, so I'm building an iOS app that allows people to search a zipcode and then it will return all of the restaurants currently open within a certain radius. I got the Google Maps API setup properly, but I'm running into issues with how to get that info.

I looked at the Google Places API and it looks like I will be able to get a JSON result and then I can just look for the "open_now" : true key/value. Currently, there is a Google Places API for Android and Javascript, but the iOS one is still in beta. Can I use this Javascript API to pass the JSON into my Obj-C code for iOS Development? Thanks!

Wait, are you looking for Objective-C or javascript? That's confusing. Perhaps this is what you are looking for: https://code.google.com/p/gdata-objectivec-client/ — briosheje, Apr 27 '15 at 18:34

To use the Google Places API make a simple POST request with AFNetworking

For example:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"key": @"YOUR_KEY", @"location": @"YOUR_LOCATION"};
[manager POST:@"https://maps.googleapis.com/maps/api/place/nearbysearch/" parameters:parameters success:^(AFHTTPRequestOperation *operation, id   responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

Now with the json "responseObject" you can do anything

Try to parse it with json-framework

Wow, so this is all I need to get the json object? Awesome! – prisonbreakx Apr 27 '15 at 19:40 — prisonbreakx, Apr 27 '15 at 19:40

You're probably looking for info on how to parse JSON with Objective-C: How do I parse JSON with Objective-C?

In a nutshell, use the NSJSONSerialization class to convert JSON to Foundation objects and Foundation objects to JSON.

You don't need the javascript API for that task. The Google Places API belongs to the Google Maps Web service suite, so you just need to make a http request in order to retreive the data.

Making http requests on obj-c is addressed in here and you'll just need to parse the JSON response.
