On February 21st (tomorrow), I'll present the Delphi iOS Preview webinar, along with JT and Sarina. I'll cover database access, including SQLite and InterBase, but also use of the ClientDataSet and more.
If you still haven't signed up (and if there is still room, as it is going to be "virtually" crowded!), do so at http://edn.embarcadero.com/article/42909. Three timezones, as common for Embarcadero webinars.
As mentioned, I'll follow JT introduction and Sarina section on styles and iOS native support with a few demos showing database access. Here are two images (in the simulator) for two of them. The first is a rather simple TClientDataSet example (very standard while not EOF loop on the table, loaded form a CDS file deployed to the device). You'd probably recognize the data. The second uses the TIdHTTP Indy client component and the TXMLDocument component (with the ADOM engine) to retrive the RSS of DelphiFeeds and display a summary:
Hope to see all of you online tomorrow! Stay tuned for more demos and information on Delphi for iOS.
