TRICK: Detect iPad vs iPhone/iPod Touch?

[Javira]

I use the iOS Get Device for disabling features on low end devices, but what if you want to simply detect if you are on an iPad or an iPhone/iPod Touch, even for future devices.

Maybe there is another way of doing this, but this is really simple.

Step 1
Include window control object.

Detect iPad:
Run this event once
ScreenXSize(WindowControlObject)>640

Detect iPhone/iPod:
Run this event once
TouchScreenXSize(WindowControlObject)<640

This works even when you stretch your app to fill canvas. On iPhones and iPod Touch the ScreenXSize returns 320, and on iPad 768 for some reason. I feel safe doing this as I have testet it on iPad 1st gen, iPad 2nd gen, iPad 4, iPod Touch 4th gen and iPhone 4. But I would like to hear results on 5th gen devices? Please share.

But why??
I am making an app with edit boxes, but unfortunately text is rendered differently on iPad vs iPhone. So to control the font size I use the trick above.

Note:
Run this event once is really important, or you will get very low performance. You can of course use any other number between 320 and 768, I just expected it to return 640.

You might try using the "storyboard controls"

Set aside 4 global or alterable values
Always: set alt val A to x coordinate of left visible edge, set alt val B to x coordinate of right visible edge, set alt val C to y coordinate of top visible edge, set alt val D to y coordinate of bottom visible edge.

Then compare those values to get the screen size.

Thanks, but it doesn't work if you have set your app to stretch to fill.

I haven't thought about using window control on ios, most functions wouldn't work.. what you say means window control get sizes in portrait mode, it doesn't change on landscape apps?
On iphone retina, the xsize should return 640, so i would just use <700 or >700, since ipad is 768 or 1536.

Thanks,
This is great for HTML5 too as far as I can tell!
