Question

我是iOS开发的新手，请关注我的问题。

正如我的标题所说，

如何将UIView（ with Animation ）隐藏并显示为UIActionSheet？
在谷歌搜索，芽没有找到有效的解决方案..

注意： i found following line but its not help me.

Answer 1

请尝试以下代码：

- (IBAction)showTapped:(id)sender {
    hideButton.enabled=YES;
    showButton.enabled=NO;
    [UIView animateWithDuration:.5 animations:^{
        subView.frame=CGRectMake(0, 225, subView.frame.size.width, subView.frame.size.height);
    }];
}

- (IBAction)hideTapped:(id)sender {
    hideButton.enabled=NO;
    showButton.enabled=YES;
    [UIView animateWithDuration:.5 animations:^{
        subView.frame=CGRectMake(0, 480, subView.frame.size.width, subView.frame.size.height);
    }];
}

在这种情况下，您可以做的是在窗口上添加UIView，然后在需要时显示它。所以，首先你需要创建一个AppDelegate的对象。

AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];

创建您的视图

 CGRect frame = CGRectMake(0, 460, 320, 300);
 UIView *ActionView = [UIView alloc]initWithFrame:frame];

这是为了在窗口上显示您的视图，请注意您的视图的 y坐标应低于屏幕尺寸，以便您可以将其恢复到某个级别，然后发送它再次下降。

[appDelegate.window addSubview:ActionView];

然后只需添加这些自定义动画即可显示和隐藏您的视图

揭示你的观点

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.25];
CGRect rect = [ActionView frame];
rect.origin.y = -300;
[ActionView setFrame:rect];
[UIView commitAnimations];

隐藏您的视图

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.25];
CGRect rect = [ScrollView frame];
rect.origin.y = 460;
[ScrollView setFrame:rect];
[UIView commitAnimations];

最后，您可以根据自己的尺寸和框架进行调整。希望这会有所帮助...

试试这个解决方案....它有效

#pragma mark - Date Selector View PresentModelView with Transparent ViewController

- (void) showModal:(UIView*) modalView {

    UIWindow *mainWindow = [(AppDelegate *)[UIApplication sharedApplication].delegate window];

    CGPoint middleCenter;


    middleCenter = CGPointMake(modalView.center.x, modalView.center.y);

    CGSize offSize = [UIScreen mainScreen].bounds.size;

    CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5);
    modalView.center = offScreenCenter;

    if ([[mainWindow subviews] containsObject:modalView]) {
        [modalView removeFromSuperview];
    }


    [mainWindow addSubview:modalView];

    [mainWindow bringSubviewToFront:modalView];
    // Show it with a transition effect
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.3];
    // animation duration in seconds
    modalView.center = middleCenter;
    [UIView commitAnimations];

}

// Use this to slide the semi-modal view back down.
- (void) hideModal:(UIView*) modalView {

    CGSize offSize = [UIScreen mainScreen].bounds.size;
    CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5);
    [UIView beginAnimations:nil context:(__bridge void *)(modalView)];
    [UIView setAnimationDuration:0.3];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(hideModalEnded:finished:context:)];
    modalView.center = offScreenCenter;
    [UIView commitAnimations];

}

- (void) hideModalEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {

    UIView *modalView = (__bridge UIView *)context;
    [modalView removeFromSuperview];
}
