iPhone Native Alert/Popup HELP

I am trying to write some Objective-C so that I can call a function similar to this in javascript inorder to open a native alert on an iOS device. I am in need of this ASAP so any help is greatly appreciated. I would like to be able to open the alert like this. displayAlert(“Alert Title”, “Alert Message”);

Hi Guys, You can use plugin to show native alert in your unity app/game.
