iOS game launches off-center on some phones, sometimes

[KelsoDisc]

Hi. I'm developing an iOS game. I'm using Animate CC and Flash Develop using Air for deployment and working on a PC.

Here's the problem. On iPhone 6 the game shows the splash screen and then launches fine. On iPhone 6 PLUS the game shows the splash screen fine, but then sometimes launches off-center. Repeat it only does this sometimes. It's not every time but it's alot. Screen shots below.

So just by looking at this picture myself. It looks like the game gets stuck thinking it's on a different device. The game logo is set to appear at stage.stageHeight / 3.45; Assuming that line is working correctly, then for some reason the game thinks the screen is bigger than it is..ofcourse, i have NO idea why the xposition is so off. Also, the game totally freezes at this point (just showing the partial logo) whereas it will run smoothly on the times that launches correctly.

I have a feeling it has something to do with my splashscreen files and/or the way I'm setting up something in my xml or settings. Here's what I have going on.

Main Animate File size: 750x1334

Air Version: 25.0

In my document main class:

stage.scaleMode = StageScaleMode.NO_SCALE;

stage.align = StageAlign.TOP_LEFT;

stage.scaleMode = StageScaleMode.NO_BORDER

(I manually position  ui/game elements via code, based on "fullScreenWidth/Height" later in the code.)

My goal is to target just iPhone 5,6,7, 6plus, and 7plus at the moment, here are my splashscreen included files:

Default-414w-736h@3x~iphone.png

Default-375w-667@2x~iphone.png

Default-568h@2x~iphone.png

And this is from the xml file:

<autoOrients>false</autoOrients>

<fullScreen>true</fullScreen>

<aspectRatio>portrait</aspectRatio>

<renderMode>direct</renderMode>

Maybe I missed something? ..something super easy I hope!

I did some estimating, and it looks like my app, when not working, thinks it's on a device with a stage size of approx 2300x2900. (This is based on how the background image and logo are incorrectly placed and also how they are coded to be placed. Any idea why it's doing this?

Maybe I'm not even on the right track here...

This is still not solved, but I have an update. I recently got my app running on iPad Air 2. It loads and runs perfectly about 50% of the time. The other 50% it looks like this (below). Notice the space on the right edge. Basically, the launch image is fine, but once the app loads it moves (just like in iPhone 6+/7+). This time, the app shifts to the left like..20px? Also, the app thinks it has much more vertical space than it really does - notice how my UI elements continue well below the bottom edge of the screen.

This test was done using AIR 25.

It's really hard to figure this out because it only happens 50% of the time. I can close the app, restart it and it will work. Sheesh...

I have a feeling that this has to do with your getting the stage size immediately.  In my experience some devices do not launch with the final stage size.  Thus what I've done is add a stage resize event.  Once that even is called, you can set global variables for stage width/height as well as begin placing things and arranging them on the stage. 

One other thing to note is that I use Stage.stageWidth and Stage.stageHeight to get the dimensions as opposed to fullScreenWidth/Height.

Hopefully one of these tips works for you.
