Body
I found/created a solution that at least works for me. with the above method (createRemoteDir), the following code applied and worked for me: <pre><code>NSError *error; createdDirectory = FALSE; /* only 'prepares' the stream for upload - doesn't actually upload anything until the runloop of this background thread is run */ [self createRemoteDir]; NSRunLoop *currentRunLoop = [NSRunLoop currentRunLoop]; do { if(![currentRunLoop runMode: NSDefaultRunLoopMode beforeDate: [NSDate distantFuture]]) { // log error if the runloop invocation failed error = [[NSError alloc] initWithDomain: @"org.mJae.FTPUploadTrial" code: 23 userInfo: nil]; } } while (!createdDirectory && !error); // close stream, remove from runloop [ftpStream close]; [ftpStream removeFromRunLoop: [NSRunLoop currentRunLoop] forMode: NSDefaultRunLoopMode]; if (error) { // handle error } </code></pre> It runs in a background thread and creates the directory on the ftp server. I like it more than other examples where runloops are only run for an assumed small interval, say 1second. <pre><code>[NSDate distantFuture] </code></pre> is a date in the futur (several centuries, according to Apples documentation). But that's good as the "break-condition" is handled by my class property createdDirectory - or the occurance of an error while starting the runloop. I can't explain why it works without me explicitly attaching an input source to the runloop (NSTimer or NSPort), but my guess is, it is sufficient that the NSOutputStream is scheduled in the runloop of the background thread (see createRemoteDir).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
