自定义push和pop特效

push

// push 动画 渐变过度
    CATransition* transition = [CATransition animation];
    transition.duration = 0.5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionFade;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    [self.navigationController pushViewController:sort animated:NO];
    [sort release];
    sort = nil;

 

pop

CATransition* transition = [CATransition animation];
    transition.duration = 0.5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionFade; 
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    [self.navigationController popViewControllerAnimated:NO];
