      <title>iOS Exception: "Dropbox client already authorized"</title>

      <description>&lt;P&gt;While developing my code for using the new Objective-C SDK, I am running on the Xcode emulator. &amp;nbsp;The first time I tried OAuth, it worked and brought up the Dropbox login web page. &amp;nbsp;NSLog verified that the OAuth result was success. &amp;nbsp;The second time I ran it there was an exception thrown saying "A Dropbox client is already authorized". &amp;nbsp;How can I properly ensure there is no authorized client before I start to create a new one, or otherwise avoid this exception? &amp;nbsp;The call stack is:&lt;/P&gt;

      <description>&lt;P&gt;In the emulator I selected a different device, which causes the iOS to reboot. &amp;nbsp;Then the error went away. &amp;nbsp;So perhaps the exception was a side-effect of stoping the app with Xcode and starting it up again. &amp;nbsp;But that leads me to wonder if there aren't some scenarios in real devices where something like this happens and an inconsistency is generated. &amp;nbsp;In that case I would like to know what addition steps I can take when starting an OAuth to ensure this exception will not occur. &amp;nbsp;I cannot use the presence or absence of a stored Access Token, but my data state might be inconsistent with the Dropbox system and I might not have a stored Access Token even though the SDK thinks I should have one.&lt;/P&gt;
&lt;P&gt;**** Edit: I tried rebooting the emulator and the exception in OAuth remains. &amp;nbsp;There is something persistent in the iOS the remembers there was a successful authorization, but it has nothing to do with my app. &amp;nbsp;I just saw&amp;nbsp;[DropboxClientsManager &lt;SPAN class="pl-c1"&gt;unlinkClients&lt;/SPAN&gt;]; in the example app. &amp;nbsp;Will this do it, and is it safe and reasonable to call this every time, just before authorizeFromController, even if there is no existing authorized client?&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi Robert, that assertion is actually easy enough to hit if you call&amp;nbsp;authorizeFromController more than once (if you do link an account the first time). The&amp;nbsp;DropboxClientsManager class is meant as a convenience for the standard single account case, so you can&amp;nbsp;use the following to check if you're already linked:&lt;/P&gt;
&lt;PRE&gt;if ([DropboxClientsManager authorizedClient] != nil) {&lt;BR /&gt;&lt;BR /&gt;// already linked, use authorizedClient to make API calls&lt;/PRE&gt;
&lt;P&gt;That's the same thing the SDK checks for that assertion, and it's set by checking the SDK's own access token storage, so you shouldn't have to worry about inconsistency there. (If you're doing your own access token storage for some reason though, you should just construct DropboxClient objects directly.)&lt;/P&gt;</description>

      <description>&lt;P&gt;Also, in response to your edit, you don't need to call unlinkClients each time, though that will clear out authorizedClient if that's what you want to do.&lt;/P&gt;
&lt;P&gt;You can re-use the tokens the SDK stores for you without having the user go through the app authorization flow each time (authorizeFromController).&lt;/P&gt;</description>

      <description>&lt;P&gt;I think the confusion comes from my trying to persist&amp;nbsp;the Access Token myself instead of letting DBKeychain do it. &amp;nbsp;In the Android version, I don't think there was any choice. &amp;nbsp;If we wanted the Access Token to persist between sessions, we had to store it ourselves in the app Preferences. &amp;nbsp;But for the iOS version, it appears the only reason to deal with an Access Token in my code is if the Access Token were manually generated externally. &amp;nbsp;If I understand correctly, the SDK for iOS will automatically persist the Access Token upon a successful OAuth2. &amp;nbsp;(I was actually getting the Access Token from the DBAuthResult.accessToken.accessToken. &amp;nbsp;But apparently that is unnecessary?) &amp;nbsp;Let me know if I should eliminate all explicit references to an Access Token in my application code, as long as I only intend to use Access Tokens that have been generated through the OAuth flow in that app itself.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;That's correct.&amp;nbsp;The Android SDK doesn't do it for you, but the iOS SDK does automatically store access tokens in the keychain for you, so you don't have to.&amp;nbsp;&lt;/P&gt;</description>
