iOS 3.1.3 can run iOS 4.0+ Apps?

firemaplegames

Hey All,

I could use some clarification.

I am in the process of doing serious heavy testing for my new game.
Right now I am setting up the GS Viewer on all of the iDevices.

On my iPhone 2G - the first one, the worst of the worst -
I have the latest software version available installed: 3.1.3

I built the latest version of the GS Viewer onto it, 0.8.9, and it runs great.

I have XCode set up so that the first drop-down menu says: Device - 4.0 | Release
This installed the viewer just fine on the iPhone 2G.

This same setup also installs the viewer just fine on my newer devices, which are running iOS4+.

My question is this:

Our GS Apps just run fine on all the versions of iOS 3+ ?

I don't have to do anything?
Hopefully not, which is great!

I just wasn't sure if newer iOS4 apps with multitasking, etc. would just work on the older devices.
I guess they have to, or the whole App Store would break!

I am pretty psyched that my game runs so well on this old dog...
Apart from some slow loading times between Scenes - which is unavoidable on this device -
my game runs pretty nicely at a steady 50 FPS.

Yeah, multitasking doesn't restrict the OS, neither does iAds

Multitasking with OS 4.0 will not work on the 2G or the 3G, the feature only works on the GS or higher. I have it installed on a 3G, only my 3GS does.

I'm not sure if you read this, but this has nothing to do with what you posted.

Not sure what you are talking about, guess you did not read his post.

He said "I just wasn't sure if newer iOS4 apps with multitasking, etc. would just work on the older devices.", and I am saying both the devices he tested with do not support multi-tasking as an FYI.

Thanks, guys.

Yeah, I just didn't know if iOS 4 apps would work at all on a device with iOS 3 installed.

GS only works with iOS 3 and above. When I was working on my first game a few months ago, a lot of people still had iOS 2 running on their devices.

I remember trying to show someone my game on their iPod Touch and a warning dialog popped up saying that you needed to upgrade the OS to use this app, or something to that effect. They would have had to buy and download the new OS for 5$ or something, upgrade, sync, etc. etc... Needless to say, I didn't make the sale!

I was just concerned that something like that would happen again, i.e., "You need iOS 4 to download this app."

But it seems like the new apps will work on iOS 4 and still downgrade just fine to iOS 3 as well.

I understand that multitasking does not work in iOS 3.

@tymemaster, chosenonestudios is right. FMG wasn't asking if you could multitask on the older devices. He was asking if the newer ios4 apps that have the ability to multitask would be able to run on devices with ios3+

TymeMaster

Right about what? I posted an FYI because the way the post was written. There is no right or wrong.

Read exactly what was in the post, here I will copy it:

"I just wasn't sure if newer iOS4 apps with multitasking, etc. would just work on the older devices."

Now do you see why I replied?

PS: There are two places to set the version in XCode. We are setting the SDK for 4.0, but we are not targeting 4.0 (if we did, nothing would run on an older OS).

You still don't get it. He was asking if he had 4.0 enabled apps "multitasking etc." if these apps, would work on the old firmware.

Edit: arton beat me to it.

Not sure why you are looking to start an argument, what you don't get I was just posting it as FYI as I had said repeatedly now. All I am trying to do is be part of the discussion

/ Dropped it

TymeMaster

It's all good man, I was just wondering what I had done wrong! Hehehe

PS: Yeah if you jailbreak, of course

chosenonestudios

Sorry, not a very a good intro, welcome to the forums! I hope you enjoy using GS, it really is a great program, (used within its limitations of course). Glad to see some fellow Floridians here!

TymeMaster

Nothing to be sorry about! I'm hoping that Game Salad fits my needs, I want a fast way to market! If cash was easier in the app store, I would stick with ObjC and maybe Cocos2D, but it is much easier to use something like this.

Speaking of Florida, with all the damn thunderstorms it's amazing that we even have power

Yeah its missing some crucial things like arrays, social networking, access to device features etc. But the input to output work really is incredible. Especially when compared to traditional programming.

Actually some of my neighbors, a couple blocks down were out of power earlier today. Lucky I wasn't affected! Hah

I'm not going to let this drop that easy. YOU'RE F****NG WRONG!!!!! Haha only kidding, welcome to GS and hope to see some big titles from you

Hehe
