Zoom Google Map from different ViewController - iOS

Question

Scenario

I have a TabBarcontroller with 2 tabs.

I have GoogleMap's Map on ViewControllerA (Tab 1).

I'm currently on another view controller, let's say ViewControllerB (Tab 2), which has a UITableView , and obviously, the map is not visible here.

Problem

Now I call a function (via delegates) in ViewControllerA , to zoom the map to a particular location, but it doesn't zoom it until I switch back to Tab 1. (As soon as I switch to Tab 1, the map zooms to that location in an eye's blink.

Is there anyway to zoom the map without opening that Viewcontroller?

Please Help. Thanks.

Answer 1

I'd try using a singleton design pattern, basically create a singleton reference to the GoogleMap object and set the zoom and try:

[mapSingletonObjc setNeedsDisplay];
