Upgrade api v1 to v2 (objective-c)

[m-grachev]

I import  ObjectiveDropboxOfficial sdk in my project. But I have a problem with logining without installed Dropbox app on device, and also on the simulator (iOS 9 and 10).
After calling  DBClientsManager authorizeFromController.... I have empty white screen and input in log

DBSDKReachability Flag Status: -R ------- networkStatusForFlags

-canOpenURL: failed for URL: "dbapi-2://1/connect" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

-canOpenURL: failed for URL: "dbapi-8-emm://1/connect" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

I use only iPad.
I upgraded project from api v1 -> v2 by instruction

<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>dbapi-8-emm</string>
        <string>dbapi-2</string>
    </array>

If installed Dropbox app all works as well. Also I tried Clear project and remove DerivedData. 
Please help.

If the official Dropbox iOS app is installed, the SDK will automatically use that for the app authorization flow. (That way, the user doesn't have to sign in again.)

This message can happen when the SDK checks if the official app is installed, and this error code indicates that it is not. This should be safe to ignore though, as the SDK should automatically handle this and fall back to the in-app version of the authorization flow.

It sounds like that's where you're seeing a white screen though, instead of the app authorization page. Can you share a screenshot of your app at that point so we can make sure we understand what's happening? It sounds like there may be an issue loading the page, so make sure nothing is interfering with the network requests to www.dropbox.com.

Also, please let us know the version number of the SDK you have installed. Thanks in advance!

It looks like you are receiving the API v1 deprecation warning because you have not yet acknowledged the API v1 deprecation.

Please login to Dropbox and go to https://www.dropbox.com/developers, and the click the acknowledge button on the big yellow banner that appears. Then, this warning will go away.

Please let me know if you have additional questions.
