DropboxClientsManager authorizeFromController not doing anything
Hello,
I'm having trouble presenting the Dropbox login to the user. I had it working some time ago, but today I tried it and nothing happens. I make this call and nothing happens.
[DropboxClientsManager authorizeFromController:[UIApplication sharedApplication]
controller:VC
openURL:^(NSURL *url) {
[[UIApplication sharedApplication] openURL:url];
}
browserAuth:NO];
I've tried it with browserAuth set to YES too, and get the same problem. Has anything changed recently?
I don't see any errors or any text at all on the console. Any idea what could be the problem?
Thanks
Bob
Hey Greg,
Finally found it. I was skipping the call to DBClientsManager setupWithAppKey! It was in there, but I was mistakenly skipping it when my app had stored the preference that Dropbox was disconnected. It's weird that that produces no error messages. I found the problem by stepping in the debugger into authorizeFromController and noticing that both my sharedApplication and controller arguments were 'nil', even though they were valid values when I passed them. Then I noticed the assert in that function:
NSAssert([DBOAuthManager sharedOAuthManager] != nil, @"Call `Dropbox.setupWithAppKey` or `Dropbox.setupWithTeamAppKey` before calling this method");As soon as I saw that, I knew what I had done.
I guess that the assert never fired, because [DBOAuthManager sharedOAuthManager] is a valid number even if you have not called setupWithAppKey?
Anyway thanks for helping me with this problem, I really appreciate it. I'll probably run into more but at least this one is down.

Hi Bob, since this was previously working for you, can you check your version control repository to see what may have changed here in your code? Or, did this stop working when you updated the version of the Dropbox SDK you're using?
In either case, is your "VC" parameter your view controller instance? Normally that's just provided as "self" (e.g., as shown in the documentation: https://github.com/dropbox/dropbox-sdk-obj-c#handling-the-authorization-flow ).Well, when I say it was working, I remember it working once, but I haven't tried it in a long time. I've been logged in so haven't really tested the login/logout stuff in a while. The Dropbox version is the same, I haven't updated it -- until just now, I thought I would try updating it to see if that fixed the problem, but it did not.
Yes, VC is the view controller, which would be 'self' if the calling object was the viewController, but in this case it is not.
I will take another look at this tomorrow, maybe it will be clearer. I think my other app is working OK, so I will try to see what the difference is with it.
Thanks,
Bob

Thanks! In that case, comparing against your other app or the DBRoulette sample app would be a good place for begin troubleshooting this, since you're not getting any error or output.
The DBRoulette sample app does use the sample authorization flow. It's available as three versions, one for each of the supported installation methods. Give that a try when you get a chance and let us know if it does or doesn't work for you.
