#import <QuartzCore/QuartzCore.h>

- (void)showNextView {
	[self.view addSubview:nextView];
	CATransition *animation = [CATransition animation];
	[animation setDuration:0.5];
	[animation setType:kCATransitionPush];
	[animation setSubtype:kCATransitionFromRight];
	[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
	[[self.view layer] addAnimation:animation forKey:@"SlideView"];
}

- (void)hideNextView {
	[nextView removeFromSuperview];
	CATransition *animation = [CATransition animation];
	[animation setDuration:0.5];
	[animation setType:kCATransitionPush];
	[animation setSubtype:kCATransitionFromLeft];
	[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
	[[self.view layer] addAnimation:animation forKey:@"SlideView"];
