@anders: very intresting that 3D form perform better, i may try that tonight (note to self: backup everthing before!)

@Olecramoak: what’s your app name? i’d be intrested to see a finalized delphi product.

I only have one form in my app and use layouts (10 of them) to contain each view’s content. It is not a good solution, because it causes startup to be slow. All components are loaded on OnCreate (after optimizing it takes avarage 5.5s on iPhone 4S and 4.8 on iPad 2, and this seems to be Apple’s limit) and still take them some time be displayed when its parent layout becomes visible, like they have not been loaded before. A bit weird.

I tried to use the multiple-forms approach, as it seems more elegant and better in any ways, but got a "project cannot be parsed" error multiple times on Xcode, so gave up on it. I guess I messed something up when adding new forms to the project. A single form is better in just a few thing: makes easier to handle OnResize eventes (rotating device) and other global events.

Just tried to convert my HD Form to 3D, but could not do it Changed my main form on my unit from TForm to TForm3D. Got a few messages about invalid properties regarding background (gradients) and ignored. Got a fatal error from IDE about invalid .Fill Property. :(:(:( Am I doing something wrong?

Can I e-mail you the sample StoreKit code? Shoot me some random message (on the unpublished post e-mail) so I have your e-mail address.

Also, I didn’t realize you could change the price from Free to Charge. I only had Free apps before, and to submit Charge apps requires contracts and all, so I did that to make sure that they would approve a FMX app. Very cool that they did of course.

What performance issues did your app have? Were you creating all forms on startup, or on demand? I’m creating all my forms on demand (except the main form). MyEDN (in review) has 7-8 forms and opens in about 2-3 seconds on my iPhone 4.

BTW, if you do stuff in OnCreate of the main form then the splash screen will be showing the entire time you do. Whatever you can postpone until the UI is open is a good thing.

Full review rejection note (Reminder: after optimization the app got):

"10.6: Apple and our customers place a high value on simple, refined, creative, well thought through interfaces. They take more work but are worth it. Apple sets a high bar. If your user interface is complex or less than very good it may be rejected

We found the user interface of your app is not of sufficient quality to be appropriate for the App Store. Apps that provide a poor user experience are not in compliance with the App Store Review Guidelines.

Specifically, we noticed your app has poor and slow performance issues. When the app is launched there is a delay of ten seconds before the user is able to proceed into the app."

if porting the app to a 3D form (it is a 2D app) is possiblr and give me better performance, will submit it as an update soon. Meanwhile, really excited with current version on the appstore

@jens: getting the storekit to work was not an easy task. Could parse it easily with phil hess parser, but the framework is not trivial to use. Some of anders components gave me a few useful clues (mainly observers and delegates) that are necessary for storekit callbacks… Many hours of development later, it works like a charm. I sell more than 10 items inside my free firemonkey app on the appstore. If anders would be interested i could send him a portion of my code for future reference to a component.
