在UIActionSheet上添加UIView作为subView [英] Add UIView as subView on UIActionSheet

问题描述

我正在开展项目，我希望用三个按钮显示UIActionsheet更改，取消和完成，在标题的位置我想放置有一些标签的UIView。我创建了动态UIView并将其添加到actionsheet但是它隐藏在按钮后面我尝试了所有可能的方法来设置setFrame，但是我无法找到解决方案。我想把这个UIView放在UIActionsheet的顶部，然后是按钮。如果您有任何疑问，请随时发表评论。

I am working on project where I want to show UIActionsheet with three buttons Change,Cancel and Done and at the place of title I want to put UIView which has some labels. I have created dynamic UIView and I added it to actionsheet but its hiding behind buttons I tried it by all possible ways to setFrame,bounds but I am not able to find solution. I want to place this UIView at the top of UIActionsheet followed by buttons. If you have any doubts feel free to post comments.

这是我的代码：

-(IBAction)tapbutton:(id)sender
{
Lablesubview *view = [[Lablesubview alloc]init];
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                               delegate:self 
                                      cancelButtonTitle:@"Cancel" 
                                 destructiveButtonTitle:@"Change" 
                                      otherButtonTitles:@"Done",nil];

   [actionSheet addSubview:view];
   [actionSheet showInView:self.view];
}

推荐答案

您可以使用此方法，它会将所有按钮向下移动100个像素，请注意这种类型的修改可能会导致您的申请被拒绝

You can use this method, it will move all the buttons down by 100 pixels, please note that this type of modificaiton may result in your application rejection

-(IBAction)tapbutton:(id)sender
{   
    //create the view
    Lablesubview *view = [[Lablesubview alloc]init];
    //Set the frame
    view.frame = CGRectMake(0, 10, 320, 100);
    view.backgroundColor = [UIColor greenColor];

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                             delegate:self 
                                                    cancelButtonTitle:@"Cancel" 
                                               destructiveButtonTitle:@"Change" 
                                                    otherButtonTitles:@"Done",nil];

    [actionSheet showInView:self.view];

    CGRect rect;

    //expand the action sheet
    rect = actionSheet.frame;
    rect.size.height +=100;
    rect.origin.y -= 100;
    actionSheet.frame = rect;

    //Displace all buttons
    for (UIView *vButton in actionSheet.subviews) {
        rect = vButton.frame;
        rect.origin.y += 100;
        vButton.frame = rect;
    }    


    //Add the new view
    [actionSheet addSubview:view];
}
