Very similar question was answered here.
There is a document here describing migration changes from 10.2.x to 100.x.
The home page for the iOS runtime SDK provides many samples and sample code. Also the API reference is available.
Per the screen shots you provided:
To add a layer to a map view, you add the layer to an AGSMap through the operationalLayers property and then assign the AGSMap to your AGSMapView.
The code now would look something more like:
AGSMap* map = [[AGSMap alloc]init];
[map.operationalLayers addObject:TianDyTuLyr];
[map.operationalLayers addObject:TianDyTuLyr_Anno];
self.mapView.map = map;
Alternatively, you can add your layers to the AGSMap.basemap if that better suits your intention.
