[英]Unable to call AppDelegate openURL( ) while using the Dropbox SDK
I'm trying to add Dropbox authentication to my app, but it's showing me this error:我正在尝试将 Dropbox 身份验证添加到我的应用程序,但它向我显示此错误:
DropboxSDK: app delegate does not implement application:openURL:sourceApplication:annotation:
Below is the code in my app delegate:以下是我的应用程序委托中的代码:
let dbSession = DBSession(appKey: dbAppKey, appSecret: dbAppSecret, root: kDBRootDropbox)
DBSession.setSharedSession(dbSession)
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
if DBChooser.defaultChooser().handleOpenURL(url){
return true
}
else if DBSession.sharedSession().handleOpenURL(url){
if DBSession.sharedSession().isLinked(){
return true
}
}
return false
}
I had created an NSObject for authentication and handling other operations related to Dropbox API.我创建了一个 NSObject 用于身份验证和处理与 Dropbox API 相关的其他操作。 Below is my authentication code:
下面是我的验证码:
if !DBSession.sharedSession().isLinked(){
DBSession.sharedSession().linkFromController(viewController)
}
else{
delegate.authenticationStatus!(true, error: nil)
}
I'm getting this error after it's successfully logged in. I had also set LSApplicationQueriesSchemes in my plist and also added the URL types.成功登录后出现此错误。我还在 plist 中设置了 LSApplicationQueriesSchemes 并添加了 URL 类型。 I'm unable to find where I'm making a mistake.
我无法找到我犯错的地方。
Also I'm trying to check if Dropbox app is present or not using此外,我正在尝试检查 Dropbox 应用程序是否存在或未使用
if UIApplication.sharedApplication().canOpenURL(NSURL(string: "dbapi-1://")!){
}
But it's giving me below error:但它给了我以下错误:
canOpenURL: failed for URL: "dbapi-1://" - error: "(null)"
canOpenURL: failed for URL: "dbapi-2://1/connect" - error: "(null)"
Any help will be appreciated.任何帮助将不胜感激。
Thanks in advance.提前致谢。
Your app delegate appears to implement a different openURL
signature than what the SDK expects.您的应用程序委托似乎实现了与 SDK 预期不同的
openURL
签名。
Change the signature to this instead:改为将签名更改为:
func application(application: UIApplication, openURL url: NSURL,
sourceApplication: String?, annotation: AnyObject) -> Bool {
Do take note that this method has been marked deprecated
in the iOS 9 SDK.请注意,此方法已在 iOS 9 SDK 中标记为
deprecated
。 It will continue to work as expected for a while though.不过,它会继续按预期工作一段时间。
From or after iOS 13 adding the following func to SceneDelegate.swift seems to work:从 iOS 13 开始或之后,将以下 func 添加到 SceneDelegate.swift 似乎有效:
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
if let url = URLContexts.first?.url {
print(url)
if let authResult = DropboxClientsManager.handleRedirectURL(url) {
switch authResult {
case .success:
print("Success! User is logged into Dropbox.")
case .cancel:
print("Authorization flow was manually canceled by user!")
case .error(_, let description):
print("Error: \(description)")
}
}
}
}
