Can you preload admob DFPRequest on iOS? I know you can for interstitials, but was wondering about DFPBannerView
Create one GADBannerView and one request inapplicationDidFinishLaunching, listen to the GADBannerView's delegate method to know when it's loaded, and then present it on any view you desire. applicationDidFinishLaunching would be the earliest you could make your request. Check this example using an ADBannerView and Swift. The implementation would be the same.
