Backendless - How To Get Objects From 'Data' - ios

Question

How do I get all the objects from Backendless's database into a UITableView in my iOS app?
Looking at their Documentation, it doesn't clearly state how to get all objects. (I'm new to the platform)
Any help would be appreciated!

Answer 1

Here's how I do it in Swift (for my table of Blurb objects):
func retrieveBlurbs() {
let query = BackendlessDataQuery()
// Use backendless.persistenceService to obtain a ref to a data store for the class
let dataStore = self.backendless.persistenceService.of(Blurb.ofClass()) as IDataStore
dataStore.find(query, response: { (retrievedCollection) -> Void in
print("Successfully retrieved: \(retrievedCollection)")
self.blurbs = retrievedCollection.data as! [Blurb]
self.tableView.reloadData()
}) { (fault) -> Void in
print("Server reported an error: \(fault)")
}
}
I am also new to Backendless and really enjoying it! It's a lot like Parse, but better in a bunch of ways.

Start with this:

Then move on to this: https://backendless.com/feature-17-data-paging-or-how-to-efficiently-load-large-data-sets-in-a-mobile-app/
Both articles include concrete examples in Swift.

Try this:
- (void)viewDidLoad {
[super viewDidLoad];
[self getDataFromBackendless];
}
-(void)getDataFromBackendless {
#try {
BackendlessCollection *documents = [backendless.persistenceService of:[YOUR_TABLE_NAME class]];
currentPage =[documents getCurrentPage];
}
#catch (Fault *fault) {
NSLog(#"Server reported an error: %#", fault);
}
}
Then perform UITableView methods:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [currentPage count];
}
