iOS - Retina confusion

techdojo

Can anyone explain the workings / purpose of the "iOS" tab on the project properties?

I managed to get "retina" support working by adding some double sized resources (with an @2x suffix) and creating an entry in the Image Scales table of the project properties (ie add @2x to the end of each image - before the .png, and set the scale entry to 2) - all good.

I tested it working by hue shifting the @2x graphics and then changing the player res from iPhone to iPhone4 and re-running my app - bingo, just as expected (hot tip for noobs : You don't have to change ALL your graphics, just the "important" ones, large background images etc can probably be safely scaled without too much loss of quality and it'll save masses on your final app size!) - obviously remember to set a scaling mode, either in code or via the project properties otherwise nothing happens!

However I couldn't find any references in the docs or the ultimate guide as to what the purpose of the settings on the iOS tab were for?

I can still see my @2x images regardless of what I set the Retina Display entry too and while I suspect that "Autorotation" will allow me to pick up with and deal with orientation changes at runtime I've no idea how to handle them and pick up any "events" that might be raised.

Any advice much appreciated (unless it's from @Scouser and doubly so if it's to do with making coffee!)

So no one's used the contents of the iOS tab then?
or is @Scouser right and I'm just as blind as bat and missing something totally obvious?

Unfortunately I haven't experimented with this yet. Sorry

@techdojo,
Something for you to test.
1. What are your logical dimensions? 320x480
2. Run your app on a device player (iPhone) with the no retina, and then with the retina (on the iOS tab turned on)
3. if you have set a sufix and wondering why the @2x graphics are showing up, that's mainly because of the device.
4. The orientation change is generally between landscape left to landscape right only. so you need to make no changes, Gideros just turns the screen around. There should be (but there isn’t at the moment) an event that captures rotation or orientation. Would that be required? The screen just rotates 180˚

if there is anything else, I might need to read your post again to understand.

@OzApps thanks for the feedback, guess I'll have to fire up my mac and do some tests
