How to find out if app is running on iPhone or iPad

Hello friends,

this time it's me who has a question =)

I'm currently working on having HD iPhone-apps run in HD when they are started on the iPad. However, how do I find out if I'm running on an iPhone or iPad?

I know there's "[[UIDevice device] model]", but on the simulator, this always only says "iPhone simulator".

Then there's "[[UIDevice device] userinterfaceIdiom]", but that only works in universal apps.

Does anyone know a way to find the device type that works in simulator, too?

Thanks in advance,
Daniel

Well, I guess the answer is kind of tangled:

Only a universal app will run on both devices, and if you run it in the simulator it depends on which simulator you start it in. You can set the project/set active executable to either iPad or iPod. If you set it to iPad and the app supports iPad it will by default run as an iPad app, so IMO you don't have the means to run a universal app as a iPad app in the iPod simulator.

With other words: userinterfaceIdiom will return UIUserInterfaceIdiomPad for a universal app only if runs on a iPad device. And UIUserInterfaceIdiomPhone only if run on an iPod.

For a non universal app there is no way to run iPad on iPod anyway, and if it is an iPad app you are anyways locked into iPads way of simulating an iPod... so the project sort of tells you what device you are running on by default.

I haven't tried, but an iPod app will return UIUserInterfaceIdiomPhone even when executed on an iPad I suppose.

Not very helpful I guess but that is how I understand this matter.

Cheers Arend

patgoto has code here:

I have not tried it, though.

Thanks for your quick answers!!

Hm, I tried the code from the post, but it has the same problem as mine: it does not work on the simulator. But it was worth the try, thanks Baike!

Arend, I know my request seems a little weird. When I create a universal application, I can use the userinterfaceIdiom property to find out the orientation. But what I want to do is allow a 'normal' iPhone application that was optimized for the retina display to run in full resolution when it is started on the iPad and the user clicks the "2x" button. I already did this with Dan from "Go Usagi" in iOS 3.2, but it was a bit of a hack. With iOS 4, it's easy to do.

However, I guess if there's no other way, that will only work on a real device for now.

Okay,

that is different from what I thought is possible. I didn't know that iPhone with retina display is rendered in full size on the iPad. But it somehow makes sense. On the other hand: Why make a non universal app, if the graphic you use already would suffice for a large screen?

You're of course right, Arend: the preferable way is to create a real universal app. But if it's done properly, that takes more work, since people expect more than just scaling up the graphics. Having an "HD iPhone" version is a comprimise: its better than having no iPad version at all. And now, it's just 2 more lines of code with Sparrow =)

Hi Daniel,

I use it with a simple define and thats it

#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

works perfectly on sim and device!

Thanks asebist,

unfortunately that only works with universal applications. When you've got an application with "target device" iPhone, that always returns "UIUserInterfaceIdiomPhone". Which is a bummer

But it's not that important, as long as I get the correct information on the device (via device.model), I can live with it.

Hi Daniel,

I think that's what you need : https://github.com/erica/uidevice-extension/blob/master/UIDevice-Hardware.m

It hads some interesting properties to UIDevice.

Thanks Erika

That looks like a quite extensive class! Thanks a lot, I will try that out!!

I use this code in my apps:

bool isiPadUsed;
NSString * device = [UIDevice currentDevice].model;
 
    if ( [device hasPrefix:@"iPad"] ){
        isiPadUsed = YES;
        game = [[Game alloc] initWithWidth:768 height:1024];
    }else{
        isiPadUsed = NO;
        game = [[Game alloc] initWithWidth:320 height:480];
    }
