单击 UIBarButtonItem 时 iPhone 中的弹出窗口

发布于 2024-12-29 22:02:03 字数 297 浏览 0 评论 0原文

我想在用户单击 UIBarButtonItem 时显示弹出窗口。为了让弹出窗口在 iPhone 上工作，我搜索并找到了 WEPopover

已编辑 : 抱歉，我的问题很混乱。我试图画一些类似于 iPad 弹出框的东西，但是是在 iPhone 上。我问是否有替代方案，例如在其他视图上添加 UIView 或从 iPhone SDK 中添加新组件。

谢谢。

看一下 FPPopover

代码真的很简单，有很多自动的东西

//the view controller you want to present as popover
YourViewController *controller = [[YourViewController alloc] init]; 

//our popover
FPPopoverController *popover = [[FPPopoverController alloc] initWithViewController:controller]; 

//the popover will be presented from the okButton view 
[popover presentPopoverFromView:okButton];

Take a look at FPPopover

The code is really simple and has a lot of automatic things

//the view controller you want to present as popover
YourViewController *controller = [[YourViewController alloc] init]; 

//our popover
FPPopoverController *popover = [[FPPopoverController alloc] initWithViewController:controller]; 

//the popover will be presented from the okButton view 
[popover presentPopoverFromView:okButton];

将目标添加到您的 UIBarButtonItem 中

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:@"button!" style:UIBarButtonItemStyleBordered target:self action: @selector(showPopover:)];

，并在您的目标中执行如下操作：

- (void)showPopover:(id)sender
{

    popoverController = [[[WEPopoverController alloc] initWithContentViewController:contentViewController] autorelease];
    [popoverController presentPopoverFromRect:sender.frame 
                                            inView:self.view 
                          permittedArrowDirections:UIPopoverArrowDirectionDown
                                          animated:YES];
}

此代码改编自 WEPopover https://github.com/werner77/WEPopover/blob/master/Classes/WEPopoverViewController.m

add a target to your UIBarButtonItem

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:@"button!" style:UIBarButtonItemStyleBordered target:self action: @selector(showPopover:)];

and in your target do something like this:

- (void)showPopover:(id)sender
{

    popoverController = [[[WEPopoverController alloc] initWithContentViewController:contentViewController] autorelease];
    [popoverController presentPopoverFromRect:sender.frame 
                                            inView:self.view 
                          permittedArrowDirections:UIPopoverArrowDirectionDown
                                          animated:YES];
}

this code was adapted from the sample provided with WEPopover https://github.com/werner77/WEPopover/blob/master/Classes/WEPopoverViewController.m
