从下到上移动 UIView [英] Moving UIView from bottom to top

问题描述

如何在我的代码中从下到上移动视图:

How can I move a view from bottom to top on my code:

colorView.hidden=NO;
colorView=[[UIView alloc]init];
colorView.frame=CGRectMake(0,480,320, 480);
colorView.bounds=CGRectMake(0,200,320, 280);
colorView.backgroundColor=[UIColor greenColor];
colorView.alpha=1.0f;
[webView addSubview:colorView];
[self.view addSubview:webView];
[self createTransparentView];

那么如何在此处添加动画?

So how can I add the animation here?

推荐答案

首先，添加您的视图:

self.postStatusView.frame = CGRectMake(0, 490, 320, 460);

对于从下到上的动画添加如下:

For the animation from bottom to top add below:

[UIView animateWithDuration:0.5
                      delay:0.1
                    options: UIViewAnimationOptionCurveEaseIn
                 animations:^{
                     self.postStatusView.frame = CGRectMake(0, 0, 320, 460);
                 } 
                 completion:^(BOOL finished){
                 }];
[self.view addSubview:self.postStatusView];

用于删除视图

[UIView animateWithDuration:1.5
                              delay:0.5
                            options: UIViewAnimationOptionCurveEaseIn
                         animations:^{
    self.postStatusView.frame = CGRectMake(0, 490, 320, 460);
                         }
                         completion:^(BOOL finished){
                             if (finished)
                                 [self.postStatusView removeFromSuperview];
                         }];
