copied!<p>It's been a month since you posted this question so I'm not sure if you still need an answer, but I solved this problem by pushing all shared "entrance logic" (as I like to call it) to <code>applicationDidBecomeActive:</code> and simply store the entrance method as state in the appdelegate object. So if I come into the app from the background, then I set one flag. If I come in through a notification, I store the notification message (so I can intelligently process the notification entrance logic). If I came in through a url, then I store that url. In <code>applicationDidBecomeActive:</code> I look to see which way I came in from. Here are the states that I watch for:</p> <ol> <li>New app instance by tapping on app icon (no state set)</li> <li>Came in from background by tapping on app icon or ending a phone call, etc (only enter foreground flag set, nothing else)</li> <li>Came in from APNS (notification data is set, note this could be either new app instance or from background)</li> <li>Came in from url (url is set, note this could be either new app instance or from background)</li> </ol> <p>With all the necessary pieces of information in one place, I can intelligently decide if I want to execute the notification entrance logic, or the simple enter foreground entrance logic.</p> <p>BTW, this flow chart is invaluable! <a href="http://www.cocoanetics.com/2010/07/understanding-ios-4-backgrounding-and-delegate-messaging/" rel="nofollow">http://www.cocoanetics.com/2010/07/understanding-ios-4-backgrounding-and-delegate-messaging/</a></p>
