DBSharedApplication

@protocol DBSharedApplication <NSObject>

Protocol implemented by platform-specific builds of the Obj-C SDK for properly rendering the OAuth linking flow.

  • Presents a platform-specific error message, and halts the auth flow.

    Declaration

    Objective-C

    - (void)presentErrorMessage:(nonnull NSString *)message
                          title:(nonnull NSString *)title;

    Swift

    func presentErrorMessage(_ message: String, title: String)

    Parameters

    message

  • Presents a platform-specific error message, and halts the auth flow. Optional handlers may be provided for view display buttons (mainly useful in the mobile case).

    Declaration

    Objective-C

    - (void)
    presentErrorMessageWithHandlers:(nonnull NSString *)message
                              title:(nonnull NSString *)title
                     buttonHandlers:
                         (nonnull NSDictionary<NSString *, void (^)(void)> *)
                             buttonHandlers;

    Swift

    func presentErrorMessage(withHandlers message: String, title: String, buttonHandlers: [String : () -> Void])

    buttonHandlers

    Map from button name to button handler.

  • Presents platform-specific authorization paths.

    This method is called before more generic, platform-neutral auth methods. For example, in the mobile case, the Obj-C SDK will use a direct authorization route with the Dropbox mobile app, if it is installed on the current device.

    Declaration

    Objective-C

    - (BOOL)presentPlatformSpecificAuth:(nonnull NSURL *)authURL;

    Swift

    func presentPlatformSpecificAuth(_ authURL: URL) -> Bool

    Parameters

    authURL

    Gateway url to commence auth flow.

  • Presents platform-neutral auth flow.

    Declaration

    Objective-C

    - (void)presentAuthChannel:(nonnull NSURL *)authURL
                 cancelHandler:(nonnull DBOAuthCancelBlock)cancelHandler;

    Swift

    func presentAuthChannel(_ authURL: URL, cancelHandler: @escaping DBOAuthCancelBlock)

    Parameters

    authURL

    Gateway url to commence auth flow.

    cancelHandler

    Handler for cancelling auth flow. Opens cancel url to signal cancellation.

  • Opens external app to handle url.

    This method opens whichever app is registered to handle the type of the supplied url, and then passes the supplied url into the newly opened app.

    Declaration

    Objective-C

    - (void)presentExternalApp:(nonnull NSURL *)url;

    Swift

    func presentExternalApp(_ url: URL)

    Parameters

    url

    Url to open with external app.

  • Checks whether there is an external app registered to open the url type.

    Declaration

    Objective-C

    - (BOOL)canPresentExternalApp:(nonnull NSURL *)url;

    Swift

    func canPresentExternalApp(_ url: URL) -> Bool

    Parameters

    url

    Url to check.

    Return Value

    Whether there is an external app registered to open the url type.
