如何将UIView设置为与presentModalViewController的工作相同的动画(即[sel-presen

Question

我是ios开发的新手，现在我正在我的应用程序上做一些动画。在我的应用程序中，主视图底部有一个菜单，有两个按钮，一个用于隐藏菜单，另一个用于显示菜单[self presentModalViewController:menuView animated:YES];和[self dismissModalViewControllerAnimated:YES];功能（即单击显示按钮，从主视图底部弹出菜单view，然后单击隐藏按钮，向下移动菜单view）。我知道基本的动画像：

[UIView beginAnimations:@"ShowHideView" context:nil];
[UIView setAnimationCurve:UIViewAnimationOptionOverrideInheritedCurve];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
[menuView setAlpha:0];
[UIView commitAnimations];

如果有人知道，请帮帮我。

点击showMenuView时，执行以下操作，

- (IBAction)showView:(id)sender 
{
    [self.view addSubview: menuView];
    CGRect rect = menuView.frame;
    rect.origin.y = 480;
    menuView.frame = rect;
    [UIView beginAnimations:@"ShowView" context:nil];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5]; 
    rect.origin.y = 0;
    menuView.frame = rect;
    [UIView commitAnimations];
}

为了隐藏，

- (IBAction)hideView:(id)sender 
{
    CGRect rect = menuView.frame;
    [UIView beginAnimations:@"HideView" context:nil];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5]; 
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
    rect.origin.y = 480;
    menuView.frame = rect;
    [UIView commitAnimations];
}
- (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{
    [menuView removeFromSuperview];
}
