Migrating from old Dropbox SDK

Question

I'm migrating from the old Dropbox Obj-C SDK to the new one. I was using the following methods from the old SDK:

- deletePath: - uploadFile:toPath:withParentRev:fromPath: - loadMetadata: - cancelAllRequests

And a bunch of delegate calls:

- (void)restClient:(DBUserClient*)client uploadedFile:(NSString*)destPath from:(NSString*)srcPath metadata:(DBMetadata*)metadata - (void)restClient:(DBUserClient*)client uploadFileFailedWithError:(NSError*)error - (void)restClient:(DBUserClient*)client deletedPath:(NSString *)path - (void)restClient:(DBUserClient*)client deletePathFailedWithError:(NSError*)error - (void)restClient:(DBUserClient*)client loadedMetadata:(DBMetadata*)metadata - (void)restClient:(DBUserClient*)client metadataUnchangedAtPath:(NSString*)path - (void)restClient:(DBUserClient*)client loadMetadataFailedWithError:(NSError*)error - (void)sessionDidReceiveAuthorizationFailure:(DBSession*)session userId:(NSString *)userId

The new SDK doesn't seem to have anything like these methods - or delegates. I'm somewhat surprised that an SDK would be updated to be so completely different than what was already there. I am thinking that maybe I've got something wrong, that maybe there's another SDK I am missing? Surely it can't be that hard, despite any API changes, to maintain an SDK in a way that transitioning would be simple and intuitive, and not requiring major changes to the client code.

What am I doing wrong?

The Dropbox API v2 Objective-C SDK isn't built from the old Dropbox Core API v1 Objective-C SDK, so performing these actions works differently:

• deletePath:

Use deleteV2.

• uploadFile:toPath:withParentRev:fromPath:

Use one of the upload methods. There's an example here.

• loadMetadata:

To get the metadata for a specific file, use getMetadata. To list the contents of a folder, use listFolder and listFolderContinue.

• cancelAllRequests

The Dropbox API v2 Objective-C SDK doesn't offer a helper method like this for cancelling all requests at once. (We'll consider it a feature request though.) Instead, the methods return task objects you can track. You can then cancel any/all of the tasks as desired. For any particular task, that would look like:

DBUploadTask *req = [client.filesRoutes upload...
[req cancel];
