I'm working on an iOS project and tryingg to go Universal. How will setting changing "Standard" to "High" resolution effect my app?
My project is at 960 x 640. When I chose standard for iPhone ... it creates a 480 x 320 ipa ... which is great because it is a low res pixel game. Will AIR continue to scale my app into iPhone "Standard" resolution on an iPad 1/2? Or will the project be at 960x640 and essentially ignore the "Standard" setting?
If your project is being exported at 480x320 then it will remain at that. If you toggle high it will simply go up to 960x640. To be truely universal you should set it to high and run some detection on the available resolution to determine how best to draw your app.
Here's an extensive Adobe article on dealing with multiple resolutions and pixel densities:
I'm not entirely sure it is being exported at 480x320. It is unclear to me what effect selecting "Standard" vs "High Resolution" has on the compiled ipa. My stage is set to 960x640 ... but this is obviously scaled down for non-retina devices. When I set the AIR packager for "Standard" it appears that the app is 480x320 even on a retina device. It's just scaled up to fill the retina screen.
I want to know what happens when my project has a stage size of 960x480, but is packaged "Standard" resolution with the compatibility set for "iPhone and iPad" ... how is that app displayed on an iPad? 480x320 scaled up like on a retina phone or 960x640 like my original stage size?
If you set standard it will be 480x320 (landscape) but scaled up to 960x640. In other words if you check the stages resolution (info in the article linked) you should be told your stage is 480x320 if you have "Standard" set.
I have a couple iPad apps set as Standard (made before Retina hit) that I continue to use Standard on to this day, which still reports 1024x768 (fullscreen) despite being on Retina (iPad3 and 4).
I'll have to check Flash Builders report Monday when I get back to work, my iPads are all there. I know on 3/4 my app calculates available space and stays at standard 1024x768 resolution. I never developed for non-retina iPhone targeting iPad. I presumed it would be the same as iPad non-retina to retina. I'll report back then.
