Detailed IOS layer Transitions animation _ios

A subclass of Caanimation that is used to animate transitions, providing layers with animations to move out of the screen and move into the screen. iOS has less effect than Mac OS x transitions
Uinavigationcontroller is the animation effect of pushing the controller's view into the screen through catransition
Attribute resolution:

• Type: Animation transition types
  
• Subtype: Animation transition Direction
  
• Startprogress: Animation starting point (percentage of overall animation)
  
• Endprogress: Animation Endpoint (percentage of overall animation)

Specific code:

  Flag=true;
  UIView *view=[[uiview Alloc] initwithframe:cgrectmake (100, 100, 200, 200)];
  View.backgroundcolor=[uicolor Redcolor];
  [Self.view Addsubview:view];
  [View release];
  _lastview=view; Do no additional setup after loading the VIEW, typically from a nib. }-(void) Touchesbegan: (Nsset *) touches withevent: (uievent *) event{if (flag) {_lastview.backgroundcolor=[uicolor Yel

  //Transitions Animation--that is, animating a view.
  1: If the switch between the controller, in fact, window view to switch catransition *transion=[catransition animation];
  Sets the type of transition animation transion.type=@ "Pagecurl";
  
  Set the direction of the transition animation transion.subtype=@ "Fromleft";
  
Add animation to a view layer [Self.view.layer addanimation:transion forkey:nil];

 }

The controller switches the animation directly

 UIApplication *app=[uiapplication sharedapplication];
  Appdelegate *dd=app.delegate;
  
    Myviewcontroller *my=[[myviewcontroller alloc] init];
  Toggle the root controller, in fact, the view controller to switch views on the window. So in the transition animation to function on window
  dd.window.rootviewcontroller=my;
  Catransition *trans=[catransition animation];
  
  trans.type=@ "Pagecurl";
  trans.subtype=@ "Fromtop";
  
  [Dd.window.layer Addanimation:trans Forkey:nil];
  
  [My release];
