Hi all,
This is a follow-up on my first post. I have tried to put my App on
the iPhone device to test it and it was even slower than in the
simulator. So, as a test, I did the following: I have created a new
stack with two cards. On the first card, I put a 320x480 image and
two "Go card 2" buttons. On the second one, I put a different 320x480
image and two "Go card 1" buttons (These images are actually 480x320
images I imported using the "Import as Control" command, then resized
to 320x480). Then, I built the app and put it on my iPhone 4. The
page turns are very very slow. Even the loading of the app is slow.
And I still can't understand why. Can you help?
It shouldn't be that slow (how slow is "slow", on average?) But what you
did is a good test. From what I've heard, imported images are
inefficient on iOS and you should use referenced images instead whenever
possible. The platform is optimized to load all resources from disk.
To do that, place your images in a folder and include that folder in the
Files and Folders pane of the standalone builder. They will be placed in
the bundle in your app after it's built. In your test stack, delete the
imported images and instead create new image objects with no content,
and set their filenames to the files on disk. Use a relative path; i.e.,
if your images are in a folder called "images" then the filename of an
image object would be "images/photo.jpg".
Build the app and see if that speeds it up.
