Hi Sumudu,
initially we were concerned about the performance because of
requirements for complex UI, but at the end it was better than we hoped for.
I believe that native app would perform better, but our customer
(another software company) didn't have any performance remarks.
We implemented many details regarding performance tuning but the most
important thing was to avoid MXML as much as you can in your components.
All item renderers should be pure AS3.
Smooth view transitions impact user perception of app quality a lot and
here are some tricks we did to get there.
First we decided to cache some components.
For example, most of our views had 2 or 3 main components and we would
store references to these components in a singleton to avoid destroying
them after exiting the view.
So, when user enters the view for the second time we didn't have to wait
for these components to raise from nothing but instead injected them
'prepared' into the view.
We didn't cache everything, just several complex components that take
long to initialize. It's also possible to cache entire views but we
didn't take that route.
It can make a big difference if you organize the code execution workflow
in a way that data loading/preparing operations don't interfere with
view switching transitions.
For example, on button click we would usually show a preloader, then
load data for the next view (our controllers are cached) and when
everything is ready then activate transition that now runs uninterrupted.
Have in mind that user doesn't actually expect to get new screen
immediately because he/she knows that some data has to be loaded and
that it takes time. Preloader keeps them calm while waiting that second.
This way transition doesn't start right away, but it's executed without
glitches and it leaves good impression.
I don't have any special link/guideline to share, we got all ideas from
5-6 years of experience with Flex.
Making complex mobile apps that behave well is possible, but it takes
some extra effort to get there.
Cheers,
Tomislav

Hi Tomislav
unfortunately we couldn't try your application and it seems UI is pretty
complex too. how about the app performance do you feel any slowness
comparing to native IOS application, if there is a delay is it a acceptable
delay.
also i would like to know what are the memory optimization/performance
tuning guild lines did you follow, any document or link you could share
would be great
Thanks

My company recently completed a business tablet app for a customer. Here
you can find some screenshots:
http://www.boardpoint.eu/en/tablet.aspx
It has pretty complex UI, many custom components, real time data sync...
There were some tweaks and cheats in the process, but in the end we
produced a pretty smooth interface.
Works for iPads and Androids.
Unfortunately it's not available for public download because it's
distributed over protected enterprise app store.
Regards,
Tomislav

Hi
Has anyone got a good example of a Flex written iPad app, on the is
iStore that I can pull down and show my manager as an example of the art of
the possible ?
I still get the old, well it may be possible but it will not be as good
as a Objective C app
