How can I get access to Introductory Overlay?

问题

I would like to customize introductory overlay in my iOS app with appearance() method, but I can't find a class responsible for this overlay in API. Do anyone know how can I get an access to introductory overlay?

回答1:

We currently don't expose the introductory overlay UI class so you can change the appearance. We have raised this with our engineering team.

回答2:

Cast SDK v3 for iOS introduced GCKUIStyle. This allows you to customize appearance of all Cast Views without having a reference to any. As it contains pretty much all properties for customization.

For Introductory Overlay specifically

GCKUIStyle *castStyle = [GCKUIStyle sharedInstance];

// customize Introductory Overlay
GCKUIStyleAttributesInstructions *instructionsCtrlStyle = [[castStyle castViews] instructions];
[instructionsCtrlStyle setBackgroundColor:[UIColor darkGrayColor]];
[instructionsCtrlStyle setButtonTextColor:[UIColor whiteColor]];

[castStyle applyStyle];
