migrating from API 1 to 2 - how do I know if I have OAuth 1 tokens?

Hey Greg,

  I am getting this kind of stuff printed to the console when I use the Dropbox API.  I'm not getting errors with the API calls, though.  Is this normal?

Thanks

Bob

Hey Greg,

  I'm trying to compare the behavior of this new API with the old one. But I can't find the documentation for the old Rest API for iOS.  I want to know if the old loadFile:intoPath call (which downloads a file) automatically overwrote any existing file on the device, or if it generated an error?  It looks like it is automatically overwriting, but I wanted to make sure or find out if there was a setting for whether to overwrite or not.  I know that the new call has an argument for that.

Thanks

Bob

The old iOS Core SDK didn't have good documentation unfortunately. Here are the relevant methods/documentation in the comments though:

/* Loads the file contents at the given root/path and stores the result into destinationPath */
- (void)loadFile:(NSString *)path intoPath:(NSString *)destinationPath;

/* This will load a file as it existed at a given rev */
- (void)loadFile:(NSString *)path atRev:(NSString *)rev intoPath:(NSString *)destPath;

There wasn't a parameter for controlling overwriting at the destination.

The actual code is:

// Everything's OK, move temp file over to desired file
[fileManager removeItemAtPath:resultFilename error:nil];

BOOL success = [fileManager moveItemAtPath:tempFilename toPath:resultFilename error:&moveError];

So, yes, it seems it overwrote existing files by removing anything at the destination first, and then moving in the downloaded data (which it saved at a temporary location beforehand).

OK, great.

Also, what should I use as a replacement for this check? 

if ([DBSession sharedSession])

This is just at the beginning of the program to make sure Dropbox is there, but not necessarily logged in.  The [DropboxClientsManager setupWithAppKey:DROPBOX_APP_KEY] doesn't return any value, so I can't use that.

Thanks

Bob

It's probably fine then.  In the old version I guess there was a chance that the DBSession would fail for some reason?  

Hey Greg,

  I have everything working now.  However, when I try to upload a build to iTunes, it rejects it.  I get a bunch of errors like these:

ERROR ITMS-90087: "Unsupported Architectures. The executable for XXXXX.app/Frameworks/ObjectiveDropboxOfficial.framework contains unsupported architectures '[x86_64, i386]'."

ERROR ITMS-90209: "Invalid Segment Alignment. The app binary at 'XXXXX.app/Frameworks/ObjectiveDropboxOfficial.framework/ObjectiveDropboxOfficial' does not have proper segment alignment. Try rebuilding the app with the latest Xcode version."

ERROR ITMS-90125: "The binary is invalid. The encryption info in the LC_ENCRYPTION_INFO load command is either missing or invalid, or the binary is already encrypted. This binary does not seem to have been built with Apple's linker."

WARNING ITMS-90080: "The executable 'Payload/XXXXX.app/Frameworks/ObjectiveDropboxOfficial.framework' is not a Position Independent Executable. Please ensure that your build settings are configured to create PIE executables. For more information refer to Technical Q&A QA1788 - Building a Position Independent Executable in the iOS Developer Library."

Any idea what the problem is?  I used the Carthage method of installing the framework. 

Thanks

Bob

Yes, I followed the instructions exactly.  I tried it a couple of times.    What's weird is that earlier today it worked, but now it doesn't.  I think something about changing project targets might screw with the behavior.

I also, like that guy in the link, had some success by using Embedded Binaries earlier and then found it switching behaviors on me. I don't know, something seems flaky with that Carthage setup.    I am trying the CocoaPods method now.
