我是iOS开发的新手,现在我正在对我的应用程序做一些动画。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。我的需要是菜单的显示和隐藏功能工作如下[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视图,然后单击“隐藏”按钮,向下移动菜单视图)。我知道基本的动画,比如:
[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。
最佳答案
点击ShowMenuView时,请执行以下操作,
- (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];
}
关于objective-c - 如何为UIView设置动画,使其与presentModalViewController的工作相同(即[self presentModalViewController:child animation:YES];),我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/9494309/
