How can I check to see if a file already exists with Dropbox Sync iOS API?

[Matthew W.8]

I would like my app to test whether there is already a file at certain path before trying to upload a file to that path.

How could I do that?

I have an array called sortedFiles. Then I have

int i = 0;

    do{

        NSString *fileName = [NSString stringWithFormat:@"Pace audio/%@", [[sortedFiles objectAtIndex:i] objectForKey: @"path"]];
        DBPath *newPath = [[DBPath root]childPath:fileName];
        DBFile *file = [[DBFilesystem sharedFilesystem] createFile:newPath error:nil];

        if ( ) //and some sort of test here to see if the file already exists at this path
            [file writeContentsOfFile:fileName shouldSteal:NO error:nil];
        else {
            NSLog(@"File already exists");
        }

        NSLog(@"The number is %d", i);
        i++;

    }
    while (i < sortedFiles.count);

I've been searching the documentation and I can't think of a way to do this. At the moment, I just get an error saying a file already exists, so at least the file isn't being overwritten.

Ideas?

Thanks.

You can use DBFilesystem.fileInfoForPath:

You probably want to do that before you do createFile though.

Thanks and good catch. That worked
