【中文标题】iOS 上的共享扩展无法打开我的 react-native 应用【英文标题】：Share extension on iOS won't open my react-native app 【发布时间】：2021-01-07 04:32:36 【问题描述】：我有一个React Native 项目，我正在尝试使用Xcode 和swift 构建共享扩展。我尝试过使用https://github.com/meedan/react-native-share-menu，但它对我不起作用。我也尝试过其他库，但它们没有得到适当的维护，所以我决定自己构建一个。
我只想在我的应用中处理 url 和文本。
我首先创建了一个Share extension 并将其命名为 Share
以下是我的 info.plist 共享扩展文件

<string>Share.ShareViewController</string>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.share-services</string>
</dict>
</dict>
</plist>
以下是我的ShareViewController代码
import UIKit
import Social
import CoreServices
class ShareViewController: UIViewController
private let typeText = String(kUTTypeText)
private let typeURL = String(kUTTypeURL)
private let appURL = "leaaoShare://"
private let groupName = "group.leaaoShare"
private let urlDefaultName = "incomingURL"
override func viewDidAppear(_ animated: Bool)
super.viewDidAppear(animated)
// 1
guard let extensionItem = extensionContext?.inputItems.first as? NSExtensionItem,
let itemProvider = extensionItem.attachments?.first else
self.extensionContext?.completeRequest(returningItems: nil, completionHandler: nil)
return
if itemProvider.hasItemConformingToTypeIdentifier(typeText)
handleIncomingText(itemProvider: itemProvider)
else if itemProvider.hasItemConformingToTypeIdentifier(typeURL)
handleIncomingURL(itemProvider: itemProvider)
else
print("Error: No url or text found")
self.extensionContext?.completeRequest(returningItems: nil, completionHandler: nil)
private func handleIncomingText(itemProvider: NSItemProvider)
print("here22")
itemProvider.loadItem(forTypeIdentifier: typeText, options: nil) (item, error) in
if let error = error print("Text-Error: \(error.localizedDescription)")
if let text = item as? String
do // 2.1
let detector = try NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
let matches = detector.matches(
in: text,
options: [],
range: NSRange(location: 0, length: text.utf16.count)
)
// 2.2
if let firstMatch = matches.first, let range = Range(firstMatch.range, in: text)
self.saveURLString(String(text[range]))
catch let error
print("Do-Try Error: \(error.localizedDescription)")
self.openMainApp()
private func handleIncomingURL(itemProvider: NSItemProvider)
print("here")
itemProvider.loadItem(forTypeIdentifier: typeURL, options: nil) (item, error) in
if let error = error print("URL-Error: \(error.localizedDescription)")
if let url = item as? NSURL, let urlString = url.absoluteString
self.saveURLString(urlString)
self.openMainApp()
private func saveURLString(_ urlString: String)
UserDefaults(suiteName: self.groupName)?.set(urlString, forKey: self.urlDefaultName)
private func openMainApp()
self.extensionContext?.completeRequest(returningItems: nil, completionHandler: _ in
guard let url = URL(string: self.appURL) else return
_ = self.openURL(url)
)
// Courtesy: https://***.com/a/44499222/13363449 ????????
// Function must be named exactly like this so a selector can be found by the compiler!
// Anyway - it's another selector in another instance that would be "performed" instead.
@objc private func openURL(_ url: URL) -> Bool
var responder: UIResponder? = self
while responder != nil
if let application = responder as? UIApplication
return application.perform(#selector(openURL(_:)), with: url) != nil
responder = responder?.next
return false
以下是我的 AppDelegate 代码
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool
if let scheme = url.scheme,
scheme.caseInsensitiveCompare("leaaoShare") == .orderedSame,
let page = url.host
var parameters: [String: String] = [:]
URLComponents(url: url, resolvingAgainstBaseURL: false)?.queryItems?.forEach
parameters[$0.name] = $0.value
print("redirect(to: \(page), with: \(parameters))")
// for parameter in parameters where parameter.key.caseInsensitiveCompare("url") == .orderedSame
// UserDefaults().set(parameter.value, forKey: "incomingURL")
//
return true
我还为我的主要和共享扩展项目创建了App groups
当我尝试从 safari 分享 url 时，我可以在分享表中看到我的应用，但是当我点击我的应用时没有任何反应。感觉就像我的应用程序崩溃或什么的。我在 Xcode 控制台中也看不到任何东西。此外，当我从共享表中单击我的应用程序时，我看不到 ios 在共享 url 时显示的帖子对话框。分享文字时也会出现同样的问题
我使用 Swift 创建了一个小型原生 iOS 应用程序，它可以在https://github.com/PritishSawant/iosDevShare 获得。我正在关注这篇文章https://medium.com/@damisipikuda/how-to-receive-a-shared-content-in-an-ios-application-4d5964229701创建扩展
【问题讨论】：
ShareViewConroller 中的所有 UI 组件是什么？加载项部分可以在 viewDidLoad 中完成。您可以尝试调试共享扩展以获取更多信息。 试试，在关闭扩展之前调用 OpenURL。 【参考方案1】：我发现了这个问题。我忘了在我的主应用程序的信息列表中添加以下内容
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLSchemes</key>
<array>
<string>leaaoShare</string>
</array>
</dict>
</array>
