POJSONModel - Using & Implementing KeyMapper

Body
copied!<p>I am using JSONModel for a basic app that returns a JSON object.</p> <p>Here is a sample of the data I am returning: <a href="https://gist.github.com/ryancoughlin/8043604" rel="nofollow">https://gist.github.com/ryancoughlin/8043604</a> - Focusing on the <code>tide</code> object.</p> <p>I am trying to work in JSONModel <code>JSONKeyMapper</code> - docs here (scroll down towards the middle) - <a href="https://github.com/icanzilb/JSONModel/blob/master/README.md#magical-data-modelling-framework-for-json" rel="nofollow">https://github.com/icanzilb/JSONModel/blob/master/README.md#magical-data-modelling-framework-for-json</a></p> <p>I am trying to find out how to implement it. I understand that it takes a key path similar too:</p> <hr> <p>EDIT: From my breakpoint: <a href="http://dl.dropbox.com/u/19301636/Screenshots/rzqv.png" rel="nofollow">http://dl.dropbox.com/u/19301636/Screenshots/rzqv.png</a></p> <p>This is what <code>json</code> returns: <a href="http://dl.dropbox.com/u/19301636/Screenshots/y5mt.png" rel="nofollow">http://dl.dropbox.com/u/19301636/Screenshots/y5mt.png</a></p> <hr> <p><strong>TIDEMAPPER.M</strong></p> <pre><code>#import "TideMapper.h" @implementation TideMapper +(JSONKeyMapper*)keyMapper { return [[JSONKeyMapper alloc] initWithDictionary:@{ @"tide.tideInfo": @"tideSite", @"tide.tideSummaryStats": @"maxheight", }]; } @end </code></pre> <p><strong>TIDEMAPPER.M</strong></p> <pre><code>#import "TideMapper.h" @implementation TideMapper +(JSONKeyMapper*)keyMapper { return [[JSONKeyMapper alloc] initWithDictionary:@{ @"tideSummaryStats.maxheight": @"maxheight", @"tideSummaryStats.minheight": @"minheight", @"tideInfo.lat": @"lat", @"tideInfo.lon": @"lon" }]; } @end </code></pre> <p><strong>VIEW</strong></p> <pre><code>@implementation TideDetailViewController - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:YES]; NSString *locationQueryURL = @"http://api.wunderground.com/api/xxxx/tide/geolookup/q/43.5263,-70.4975.json"; [JSONHTTPClient getJSONFromURLWithString: locationQueryURL completion:^(NSDictionary *json, JSONModelError *err) { // NSArray* results = [json valueForKeyPath:@"tide.tideInfo"]; _tide = [TideMapper arrayOfDictionariesFromModels:json]; NSLog(@"loans: %@", _tide); }]; } </code></pre> <p>I think I need to change <code>tide</code> to <code>NSDictionary</code> - I dont think it returns an array. Its only a single result for a location</p> <p>I am stuck when it comes to calling this method. Does anyone have any experience using this JSONModel KeyMapper? </p> <p>Thanks</p>
