Info lightbutton animation - ios

Question

I am having trouble in showing infobutton to navigate to information page/view.
I have written this code.
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
UIBarButtonItem *infoButtonItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
toolBar.items = [NSArray arrayWithObjects:infoButtonItem, nil];
I got infolight button but i do not now know how to do animate & navigation action method in to flip to info page.
I also want infobutton to stay at center, currently it is at left corner.

Answer 1

This will create ur info button in center.
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
UIBarButtonItem *infoButtonItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
[infoButton addTarget:self action:#selector(goToRechercherView) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *flexibleLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
toolbar.items = [NSArray arrayWithObjects:flexibleLeft,infoButtonItem,flexibleLeft, nil];
This is for swipe animation. add your view inside.
-(void)goToRechercherView{
[UIView beginAnimations:#"flipview" context:nil];
[UIView setAnimationDuration:2];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.view cache:YES];
[UIView commitAnimations];
}

Answer 2

There are two ways to do this...
First one is......
newView setFrame:CGRectMake( 0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen!
[UIView beginAnimations:#"animateView" context:nil];
[UIView setAnimationDuration:0.4];
[newView setFrame:CGRectMake( 0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen!
[UIView commitAnimations];
Second option is to use built in animations as flip and curl:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
forView:newView
cache:YES];
[self.navigationController.view addSubview:settingsView.view];
[UIView commitAnimations];
