Create boot page [3]

Create boot page [3]

The third method is to write the entire boot page to a controller, which is the most universal way :)

Source code:

Rootviewcontroller. m

//// Rootviewcontroller. M // show // copyright (c) 2014 y. x. all rights reserved. // # import "rootviewcontroller. H "@ interface rootviewcontroller () @ end @ implementation rootviewcontroller-(void) viewdidload {[Super viewdidload]; self. view. backgroundcolor = [uicolor whitecolor]; [uiview animatewithduration: 2 animations: ^ {self. view. backgroundcolor = [uicolor blackcolor] ;}] ;}@ end

Notes:

Switch the View Controller after the animation ends.

More natural transition

 

Summary:

The core of the boot pages created in these tutorials is to load the view or View Controller on the uiwindow, which is so easy :)
