推荐答案
根据您的要求，我创建了一个示例来使其正常工作.
According to your requirement, I have created a sample to get this working correctly.
1..首先，在TodayViewController界面中，创建3个不同的UIButtons，并指定其 tag 值以唯一地标识它们.
1. First of all in TodayViewController interface, create 3 different UIButtons and give their tag values to uniquely identify them.
在这里，我给标记了:1, 2, 3至First, Second and Third UIButton.
Here I have given tags as: 1, 2, 3 to First, Second and Third UIButton.
2..接下来，您需要编写代码以从今日扩展"中打开您的包含应用程序.在TodayViewController中为创建一个@IBAction并将其连接到所有三个UIButtons.
2. Next you need to write the code to open your Containing App from Today Extension. In TodayViewController create an @IBAction for and connect it to all three UIButtons.
@IBAction func openAppController(_ sender: UIButton)
{
if let url = URL(string: "open://\(sender.tag)")
{
self.extensionContext?.open(url, completionHandler: nil)
}
}
在上面的代码中，标签将添加到 URL方案中，以标识在按UIButton键时需要打开哪个UIViewController.因此，该网址应类似于: open://1
In the above code, tag will be added to the url scheme to identify which UIViewController needs to be opened on UIButton press. So the url will look something like: open://1
3..在包含应用程序的 URL Types中，需要输入URL Scheme的条目，即
3. In the Containing App's URL Types need to make an entry for URL Scheme, i.e
从上面的屏幕截图可以明显看出，无需为要从扩展名中打开的每个URL进行输入.具有相同url scheme的 URLs只有一个条目.
As evident from the above screenshot, there is no need to make entry for each url that you want to open from your extensions. URLs having same url scheme have only a single entry.
4..从扩展程序打开包含应用程序时，可以使用AppDelegate’s application(_ : url: sourceApplication: annotation: )方法获取该句柄.在这里，您可以处理要打开哪个控制器，即
4. When the containing app is opened from extension, you can get the handle in AppDelegate’s application(_ : url: sourceApplication: annotation: ) method. Here, you can handle which controller to open i.e.
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
{
if url.scheme == "open"
{
switch url.host
{
case "1":
//Open First View Controller
case "2":
//Open Second View Controller
case "3":
//Open Third View Controller
default:
break
}
}
return true
}
url.scheme标识URL的方案，即open和url.host标识URL中当前设置为UIButton's tag value的主机组件，可用于唯一标识哪个UIButton按，然后下一步要做什么.
url.scheme identifies the scheme of URL i.e. open and url.host identifies the host component in the URL which is currently set to the UIButton's tag value which you can use to uniquely identify which UIButton is pressed and what to de next accordingly.
