Universal IOS app

[ncmac]

I am trying to create a universal (iPodiPad) app using two separate stacks. This is what I have tried (for several hours now) but it's not working. I appreciate anyone's help. Thanks!

on preOpenStack
getTheDevice
end preOpenStack

on getTheDevice
put the machine into tDevice
switch tDevice
case "iPhone Simulator"
case "iPhone"
case "iPod Touch"
go to stack "iPhonestack" --This is the substack
break
case "iPad Simulator"
case "iPad"
go to stack "iPadStack" -- This is the main stack
break
end switch
end getTheDevice

You are working too hard Try a simple if...then statement, based on the device's screen resolution:

if item 1 of iphoneDeviceResolution() = "640" then -- iPhone Retina
if item 1 of iphoneDeviceResolution() = "320" then -- iPhone 3G/3GS
if item 1 of iphoneDeviceResolution() = "768" then -- iPad...I think...don't have mine handy

Thanks. I have tried both ways (see below) and the correct stack isn't opening. I appreciate any help!

Version 1
on preOpenStack
getTheDevice
end preOpenStack

on getTheDevice
put the machine into tDevice
switch tDevice
case "iPhone Simulator"
case "iPhone"
case "iPod Touch"
go to stack "iPhonestack"
break
case "iPad Simulator"
case "iPad"
go to stack "iPadStack"
break
end switch
end getTheDevice

Version 2

on preOpenStack
if the environment is "mobile"
then
if item 1 of iphoneDeviceResolution() = "640" then go to stack "iPhonestack"
else
if item 1 of iphoneDeviceResolution() = "320" then go to stack "iPhonestack"
else
if item 1 of iphoneDeviceResolution() = "768" then go to stack "iPadStack"
end if
end if
end if
end preOpenStack

Either detection method will work. Try waiting for the startup business to finish, and then go to the stack you really want.

Put these handlers in the CARD script of the first card of the main stack. That way they won't trigger when your substacks open.

Code: Select all

on preOpenStack
 set the visible of this stack to false -- hide it
end preOpenStack

on openStack -- it's still invisible
  getTheDevice -- your substack opens here; it is visible
end openStack

I don't see any provision for the desktop IDE, so "getTheDevice" won't do anything of course if you aren't running it in a mobile environment.

Also note that after this runs once, the mainstack will be invisible forever if you save the stackfile. Use the Application Browser to see it again if you need it.

That worked. Thank you very much.

what is the script you are using to switch between stacks for iPad and iPhone. I am following this thread for mys scripting, but I just get a black screen on the actual iPad and iPhone

[ncmac]

Put this in the card script of the first card:

on preOpenStack
set the visible of this stack to false -- hide it
end preOpenStack

on openStack -- it's still invisible
getTheDevice -- your substack opens here; it is visible
end openStack

This is in the stack script

on getTheDevice
put the machine into tDevice
switch tDevice
case "iPhone Simulator"
case "iPhone"
case "iPod Touch"
go to stack "iPhonestack"
break
case "iPad Simulator"
case "iPad"
go to stack "iPadStack"
break
end switch
end getTheDevice

I just kept one stack, but having detected the size of the screen. (in the PreOpenStack), if it's an iPhone, I directed to a different card
In this way I kept all my common code in the stack script , and all the size dependent code in the card script

Code: Select all

put the screenRect into myRect
   if item 3 of myRect=1024 or item 4 of myRect=1024 then -- check both orientations
      put "ipad" into gDevice
      go to card "main"
   else
      if item 3 of myRect=320 or item 4 of myRect=320 then -- check both orientations
         put "iphone" into gDevice
         go to card "iphonemain"
      else
         put "desktop" into gDevice
         go to card "desktopmain"
      end if
   end if

Hi...

It might help you to read page 37 of the iOS release notes, 'Runtime Environment Querying'... it explains how to determine both the processor or the machine that your stack is running on... for example, for you to determine what type of device you are running on this would help...

Code: Select all

on preOpenStack
   switch the Machine
      case "iPod Touch"
      case "iPhone"
      case "iPhone Simulator"
          /* do whatever you want */
         break
         
      case "iPad"
      case "iPad Simulator"
         /* do whatever you want */
         break
   end switch
end preOpenStack

be well
