Upload request for iOS mobile app

It looks like you're running in to a few different issues, some of which aren't about the Dropbox API/SDK in particular, but I'll offer what help I can. 

NSData *fileData = [@"file data example" dataUsingEncoding:NSUTF8StringEncoding allowLossyConversation:NO];

****error#1: No visible @interface for 'NSString' declares the selector 'dataUsingEncoding:allowLossyConversation:’

It looks like you have a typo in the parameter name. It should be "allowLossyConversion", not "allowLossyConversation". You can find an example here.

DBFILESWriteMode *mode = [[DBFILESWriteMode alloc] initWithOverwrite];

*****error#2:Initializer element is not a compile-time constant

Are you trying to run this outside of a function? Doing so will produce this error. Put this inside a function instead.

[[client.filesRoutes uploadData:@"/test/path/in/Dropbox/account/yourPDF.pdf”

******error#3: Expected identifier or ‘(‘ —first bracket and client are underlined in red

The code you shared here is incomplete. Make sure you implement it like in the example. Also, put it in a function, as above.

Thank you very much.  Now, the first two are solved, but #3 remains with this new message:

No visible @interface for 'DBFILESUserAuthRoutes' declares the selector 'uploadData:mode:autorename:clientModified:mute:propertyGroups:inputData:'

I'm not sure what the Dependencies are forDBFILESUserAuthRoutes?

Controller.m code:

      NSData *fileData = [@"file data example" dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];    

    DBFILESWriteMode *mode = [[DBFILESWriteMode alloc] initWithOverwrite];

    [[[client.filesRoutes uploadData:@"/test/path/in/Dropbox/account/yourPDF.pdf"

          NSLog(@"\n%lld\n%lld\n%lld\n", bytesUploaded, totalBytesUploaded, totalBytesExpectedUploaded);

      }];

AppDelegate.m Code:

     [DBClientsManager setupWithAppKey:@"<APP_KEY_REDACTED>"];

       DBUserClient *client = [[DBUserClient alloc] initWithAccessToken:@"<ACCESS_TOKEN_REDACTED>"];

      return YES;

}

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

    DBOAuthResult *authResult = [DBClientsManager handleRedirectURL:url];

    if (authResult != nil) {

        if ([authResult isSuccess]) {

            NSLog(@"Success! User is logged into dropbox.");

        } else if ([authResult isCancel]) {

            NSLog(@"Authorization flow was manually canceled by user!");

        } else if ([authResult isError]) {

            NSLog(@"Error: %@", authResult);

              }

    }

    return NO;

}

Thanks to your help I now have all the previous issues in the code resolved, but this message came up:

   :-1: linker command failed with exit code 1 (use -v to see invocation)

Please do not share your access token. I've redacted it from your previous post, but for the sake of security, you should disable that access token since you shared it publicly. You can do so by revoking access to the app entirely, if the access token is for your account, here.

Or, you can disable just that access token using via API, using any of the following:

• HTTP endpoint
• API v2 Explorer
• Objective-C SDK method

Anyway, I'm glad to hear you resolved the other issues. Regarding the latest linker issue, please make sure you followed the installation instructions (for whichever of the three options you're using) exactly as documented. If you're still having trouble after double checking that, please try the potential fixes outlined in this issue.
