ArcGIS API for iOS implements layer Display Control in two granularities: Service display control and layer display control.
1) Service Display ControlThe service display control is implemented using agsmapview class. Each uiviewcontroller interface has an agsmapview object instance if a map is loaded. Set hidden = true for this agsmapview instance. For example, agstiledmapservicelayer * tiledlayer = [[agst

In the past, both drag and drop in IB and write in code, each UIView has its own frame attribute to define its position and size in the current view. If AutoLayout is used, it is changed to defining the position an
