Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
It might change depending on the version of iOS and the hardware it's running on (e.g. differences in calculation algorithms or filesystem block sizes). You should run a query on the database to see if it has been modified.
Also, 12,288 KB (precisely 12 MB) is very large for an empty database with one table. If it really is 12 MB, then there's something in the database already.
The logic of what you've put in the method is sound, but textFieldShouldReturn only gets called when you press the enter key. I would suggest moving that code into a separate method which gets called when the textFields' contents are changed. You could do this by adding a target for UIControlEventEditingChanged, like this:
Well, you have to change their frames as well. Only instead of changing their height, change their y position so they move down. I would suggest defining the height of your expanded menus as a variable. Then you increase the size of the view the user clicked by that number, and move the views below it down by the same number to make space for it.
Well you'll need some kind of service for that, even if it's just a web host providing PHP and MySQL. Your iPhone app can connect directly to the MySQL server if your provider will allow it, or can call PHP scripts on the web server which can then return values to the app.
