iOS: launch your app from another app

info.plist

// info.plist from Test 5
// Open your info.plist and look for CFBundleURLSchemes
// this is the string that you will use to open that app
// You can also copy the info.plist to the root of your app and edit it. 
// You can even have multiple schemes that you can use to launch it.
// Here I can launch the app using either 'test5://' or 'pedro://'
// Be SURE to do a clean build
