自定义简单的转场动画

在视图控制器中点击导航栏按钮，实现导航栏按钮和页面的转场动画

//设置点击导航栏按钮事件
- (void)buttonAction:(UIButton *)button {

    //取得导航项的父视图
    UIView *superView = self.navigationItem.rightBarButtonItem.customView;
    UIButton *button1 = (UIButton *)[superView viewWithTag:101];
    UIButton *button2 = (UIButton *)[superView viewWithTag:102];

    //将按钮的hidden值取反
    button1.hidden = !button1.hidden;
    button2.hidden = !button2.hidden;

    //将视图的hidden值取反
    _tableView.hidden = !_tableView.hidden;
    _posterView.hidden = !_posterView.hidden;

    //设置转场动画的值
    UIViewAnimationTransition animation = button1.hidden ? UIViewAnimationTransitionFlipFromLeft : UIViewAnimationTransitionFlipFromRight;
    [self flipViewWithAnimation:animation WithView:superView];
    [self flipViewWithAnimation:animation WithView:self.view];


}

//转场动画
- (void)flipViewWithAnimation:(UIViewAnimationTransition)animation WithView:(UIView *)view {

    //开始动画
    [UIView beginAnimations:nil context:nil];

    //动画时间
    [UIView setAnimationDuration:.35];

    //转场动画
    [UIView setAnimationTransition:animation forView:view cache:YES];

    //结束动画
    [UIView commitAnimations];
}
