A very basic question concerning dropBox integration into an iPhone app.

I followed the setup of the DropBoxSDK and everything works fine. I can log on to my account and

Answer 1

Into the DBdownload function you can skip the check by implementing the DBRestClientDelegate method loadedFile and loadFileFailedWithError

Answer 2

Ok, I found this method to save my example.txt file:

-(void) DBupload:(id)sender
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"Example.txt"];

    [self.restClient uploadFile:@"NoteBook.txt" toPath:@"/example" fromPath:filePath];
}

Turns out, no need to create a folder, dropbox will do this automatically for you if it doesn't exist.

This is for downloading the same file form dropbox:

-(void) DBdownload:(id)sender
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"Example.txt"];
    NSError *error;

    [self.restClient loadFile:@"/example/Example.txt" intoPath:filePath];

    if (filePath) { // check if file exists - if so load it:
        NSString *tempTextOut = [NSString stringWithContentsOfFile:filePath
                                                          encoding:NSUTF8StringEncoding
                                                             error:&error];
    }
}

Hope this helps if you were struggling with a similar question.
