Um beginner with RestKit, first example for me was on foursquare API's and I've used RestKit with Blocks not delegates.
I want to retrive the name's of venues,this is the JSON response
and this is my code:
// App Delegate.m
RKObjectManager *objectManager = [RKObjectManager objectManagerWithBaseURLString:@"https://api.Foursquare.com/v2"];
RKManagedObjectStore *objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:@"Venue.sqlite"];
objectManager.objectStore = objectStore;
objectManager.serializationMIMEType = RKMIMETypeJSON;
RKManagedObjectMapping *venueMapping = [RKManagedObjectMapping mappingForClass:[Venue class] inManagedObjectStore:objectStore];
[venueMapping mapKeyPath:@"id" toAttribute:@"id"];
[venueMapping mapKeyPath:@"name" toAttribute:@"name"];
venueMapping.primaryKeyAttribute = @"id";
[objectManager.mappingProvider setMapping:venueMapping forKeyPath:@"response.venue"];
then in myViewController.m
-(void)loadVenues{
// When caling loadObjectsAtResourcePath method it specify RKObjectLoader which is the actual request.
// within these block you can take more options to controll the request.
[[RKObjectManager sharedManager]loadObjectsAtResourcePath:@"/venues/40a55d80f964a52020f31ee3?oauth_token=FNQPN5P5EKLJ5IQ44TMWO00I3W033M0Y1TKINW2OTF2VIOTP&v=20130512" usingBlock:^(RKObjectLoader* loader)
{
loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[Venue class]];
loader.onDidLoadObject = ^(NSArray *objects)
{
NSLog(@"onDidLoadObject Blocks");
self.data = objects;
[self.tableView reloadData];
};
}
];
}
and the app is entering the block of onDidLoadObject but every time the array is empty !! even when I test the link on browser it comes with data.
When I debug the loader.URL it always come with these
https://api.Foursquare.com/v2/venues/40a55d80f964a52020f31ee3?v=20130512&oauth_token=FNQPN5P5EKLJ5IQ44TMWO00I3W033M0Y1TKINW2OTF2VIOTP -- https://api.Foursquare.com/v2 -- https://api.Foursquare.com/v2
I don't know why load.URL is wrong ?!
I think um calling the 4square API's with the wrong way, anyone can help ? :)
-Put Your mapping as a class method to be accessed from all application classes, and done only once.
-change the Attribute "id" as it is reserved in Objective-C.
-add this to the block
[loader setObjectMapping:[RestKitMapping yourMapping]];
-then add this with your mapping code
[objectManager.mappingProvider setMapping:venueMapping forKeyPath:@"response.venue"];
-And use Delegates instead of blocks
