Use the url schema. See add custom URL Schema using http://

Every Application can have customer url schemas. Like ...

yourapp://someting?withparams=1.

To get they running you have to change your Info.plist to inform the iOS that your app is handling that url schema. See the SO post above.

When another App calls that URL your app gets opened and you get a hook on your app delegate.
