从自动填充凭据提供程序扩展打开主应用程序时出错 [英] Error when opening main app from Autofill Credential Provider extension

问题描述

问题:这篇博文的目的是找出下面代码的问题，并找到合适的解决方案，从其自动填充凭据提供程序扩展目标打开主应用程序.

尝试 1:我将 URL 方案设置为打开"；如下图所示:

<块引用>

然后我尝试从我的扩展视图控制器调用这个函数:

 func openMainApp(){让 urlStr: String = "open";让 url2 = NSURL(string: urlStr)self.extensionContext.open(url2! as URL)}

在打开主应用程序之前，它在打开函数之前崩溃，并显示以下消息:

<块引用>

线程 2:EXC_BAD_ACCESS(代码=1，地址=0x10)

我认为一切都设置正确，可以打开应用程序.我错过了什么?

尝试 2:尝试新的配置以避免解包"下面的url问题和无效url问题，将url方案更改为open:"，并在print(url)"处设置断点；行以确保 url 已形成.断点变量记录在代码下方.

仍然得到:线程 3:EXC_BAD_ACCESS(代码=1，地址=0x10)

 func openMainApp(){var urlComponents = URLComponents(string: "open:")如果让 url = urlComponents?.url {打印(网址)self.extensionContext.open(url)} 别的 {打印(NIL URL")}}

解决方案

Credential Provider 扩展程序不允许打开 url.

来自文档

每个扩展点决定是否支持该方法，或者在什么条件下支持该方法.在 iOS 中，Today 和 iMessage 应用扩展点支持此方法.iMessage 应用扩展程序只能使用此方法打开其父应用，并且仅当父应用显示在 iOS 主屏幕上时.

Problem: The aim of this post is to find what's wrong with the code below and find the appropriate solution to open the main app from its Autofill Credential Provider extension target.

Attempt 1: I have a URL scheme set as "open" as shown in the image below:

I then attempt to call this function from my extension viewcontroller:

    func openMainApp()
{
    let urlStr: String = "open"
    let url2 = NSURL(string: urlStr)
    self.extensionContext.open(url2! as URL)
}

This crashes before at the open function before opening the main app with the following message:

Thread 2: EXC_BAD_ACCESS (code=1, address=0x10)

I think everything is set up properly to open the app. What am I missing?

Attempt 2: Tried a new configuration to avoid "unwrapping" of url problem and invalid url problems below, changed url scheme to "open:", and set a breakpoint at the "print(url)" line to assure url was formed. Breakpoint vars documented below the code.

Still getting: Thread 3: EXC_BAD_ACCESS (code=1, address=0x10)

    func openMainApp()
{
    var urlComponents = URLComponents(string: "open:")
            if let url = urlComponents?.url {
                print(url)
                self.extensionContext.open(url)
            } else {
                print ("NIL URL")
            }
}

urlComponents Foundation.URLComponents? some url Foundation.URL "open:" _url NSURL "open:" 0x0000000281695540 baseNSObject@0 NSObject

Title of the Thread throwing the exception:

ExtensionKit`__62-[EXExtensionContextImplementation openURL:completionHandler:]_block_invoke_2:

解决方案

Credential Provider extensions are not permitted to open urls.

From the documentation

Each extension point determines whether to support this method, or under which conditions to support this method. In iOS, the Today and iMessage app extension points support this method. An iMessage app extension can use this method only to open its parent app, and only if the parent app is shown on the iOS home screen.
