A question related to initWithNibName

Question

hi These are the steps i'm following

1. on click of home button i had set 1 value
2. so i'm clicking on home button
3. now i again click on application
4. so my applicationdidfinishlaunching method calls
5. i'm getting that value 1
6. now in applicationdidfinishlaunching method i check wether the value is 1 or not
7. now as per discussion value is 1
8. in that condition i load the 1 view which is the view of rootviewcontroller
9. but after complete execution of this viewdidload method it executes the initwithnibname of some another view

my questuon is all about why 9 number executes if it executes how to debug it?
