iOS autocomplete from JSON instead of array - ios

Question

I want to make an autocomplete with a tableView, for that I have this function :
-(AutocompletionTableView *)autoCompleter
{
if (!_autoCompleter)
{
NSMutableDictionary *options = [NSMutableDictionary dictionaryWithCapacity:2];
[options setValue:[NSNumber numberWithBool:YES] forKey:ACOCaseSensitive];
[options setValue:nil forKey:ACOUseSourceFont];
_autoCompleter = [[AutocompletionTableView alloc] initWithTextField:self.textField inViewController:self withOptions:options];
_autoCompleter.autoCompleteDelegate = self;
_autoCompleter.suggestionsDictionary = [NSArray arrayWithObjects:#"hostel",#"caret",#"carrot",#"house",#"horse", nil];
}
return _autoCompleter;
}
The Problem :
Instead of autocompleting from an Array, I want to autocomplete from a remote JSON file.
Any idea on I how I can do such thing ? A code snippet will be very helpful, as I am a newbie in iOS development.

Answer 1

After making a request to the server using NSURLConnection, you should receive an NSData containing the following data:
["hostel","caret","carrot","house","horse"]
This NSData is something like this:
NSString* data = #"[\"hostel\",\"caret\",\"carrot\",\"house\",\"horse\"]";
NSData* dataReceived = [data dataUsingEncoding:NSUTF8StringEncoding];
So, to convert it into an array, you can call NSJSONSerialization, like this:
NSError *jsonError = nil;
NSArray *responseDictionary = [NSJSONSerialization JSONObjectWithData:dataReceived options:0 error:&jsonError];
if(jsonError == nil)
{
_autoCompleter.suggestionsDictionary = responseArray;
}
