This is for avoiding an extra target and writing any target-specific adaptation code for the Ipad, separate apps on App Store, etc etc - but instead let the Iphone app display in 640x960 rather than 320x480#2x using the "2x" button.
Even on a non-retina Ipad, there's room for 640x960, but the Ipad is still running Iphone apps on the Ipad as if they were made only for Iphone 3GS.
This is for an app used internally by a company and any authorized client/partner. The company has bought Ipads, but the clients/partners may want to use the Iphones they have.
So, I'm looking for a compile-time target flag or a snippet of code to execute to detect the platform is Ipad and make it display the window full-size.
Has someone succeeded in doing this and if so, how did you achieve it?
This isn't really how things work ... you're trying to create a workaround that will probably take you longer to get to work (if at all possible) than it would if you just commit to making iPad friendly layouts.
If you just make the project a universal binary, then it would run "natively" on the ipad rather than in iphone compatibility mode. After that, the simplest thing you could do is just make sure your view's resize masks are set correctly so they stretch. Depending on the complexity and makeup of your app, many times this is enough to get you through. However, in many cases it would behoove you to just make an ipad specific layout as usability is oftentimes greatly improved.

I have created an iPhone Application, which works only on iPhone.
Now, I want that App on iPad, too.
Is there any way that I can reuse my existing iPhone XIBs to support that App on iPad. (I don't want to recreate all the XIBs for iPad separately.)
Any guidance for that?
Also, What other points I need to take care of?
Your iPhone app will work in iPad if you choose 2x zoom view. But the display will not be of the highest quality. Now rumors are there that next iPad will have retina display. So, one suggestion I can give is, when you create a new project, Choose "Universal" as the option for device family.
Depending on your app, Feature detection might be one thing you have to look out for when you try to run an app on iPad. For example, Siri is available for iPhone 4s, but not iPad 2. (Although the API for Siri isn't out yet, I'm just putting it there). Also, iPhone 4 has camera, while iPad 1 doesn't have.
Click on your target, and under "Devices" change to Universal. Now your project should run on either device.
I am new to iOS development. I am trying to figure out these things.
A project both in iPhone and iPad. what things are same for both (coding, graphics or UI)?
Design Pattern of apps are same or different?
waiting for answer
Thanks :)
Personally, I find that the only real difference between the iPhone and the iPad is the UI and UX. Most of the code is the same for both applications. (In fact, you can even reuse a lot of code if you are doing a universal app!)
The main difference really is the screen size. The iPad is huge in comparison to the iPhone, and this difference gives you a lot more options to work with.
Another thing to note is that the iPad is usually done in landscape orientation, whereas the iPhone is done in portrait. This is not an absolute rule however, it's just the way I see it.
The graphics aren't too different between the devices, except that because of the large screen size, you can do a bit more detailed work with the iPad images then the iPhone images. (Even with the retina display, too fine detail on the iPhone is barely noticeable.)
The other thing I wanted to mention is the flow of the devices. Again, because of the screen size of the iPad, you can fit a lot more content on the screen, and therefore have to push to new views less frequently. I've worked on apps where we had 3 UIViewController's for the iPhone version, and only 1 for the iPad version.
In short, it depends really on your type of app. If you have a lot of content, and want to display it all at once, go for the iPad. If you want a streamlined, minimal approach to your app, go for the iPhone.
Again, this is all just my personal opinion. Hope that Helps!
You can use native controls without much theming and customization on the iPhone. But iPad is a bigger beast. Users use your iPad app for a longer time. iPhone apps are used for a short stint and then closed, used again for a short stint and so on.
Analytics published by Flurry showed that the average time an iPhone app is kept open is about 1.2 minutes. Design and develop it in a way that data is available as fast as you can.
iPad apps are used in a relaxed setting. While I don't have the numbers, it's probably used more often and for a longer time than an iPhone app. Themes and custom UI elements do matter a lot there
Second, iPad apps need to be supported on all orientation (or at least a minimum of two orientations)
My question is simple: when an iPhone app also supports retina display, it does not need an additional xib file. (Fonts and images are auto-scaled, you just need to prepare double-resolution images.) I want that retina view also applies to iPad and hence there's no additional xib files. (Scale a bit and leave a bit margin, maybe.) Yes, I just want it look bigger, but not in the low-resolution version scaled up from 320x480.
The iPhone, even with a retina display, is not an iPad. You can update your targets and xcode will convert automatically your views to use the entire screen of the iPad, but it won't make the application conforms to
1. Apple guidelines
2. Users expectations of an universal app.
But, as I said, if you do update your targets, your app might look relatively good (just programatically use UI_USER_INTERFACE_IDIOM to use the #2x.png version of your images).
Edit: I misunderstood your question, and now the corrected answer:
There's nothing you can do. The iPad will launch the app as an iPhone app (the small non retina display, pixelated if double sized) if it is defined as such in your plist, and iTunes Connect will sell your app as universal if it isn't defined as an iPhone in the info.plist.
You basically have little choice here but to port the app or to more or less forget about iPad users. And Apple certainly wanted things to be that way...
Ive created an iPad app which we are due to send to the app store at the start of next month for approval. The boss has queried me to see whether it could also run on the iphone.I know it is quite easy to convert your app to be universal (compatible for iphone and iPad) but being all the views are designed for the ipad screen size its gonna be the process of chopping and changing to suit the smaller screen size of the iPhone.
Can anybody think of anyway i can make our iPad designed app suitable for the iPhone in a short amount of time? (if there is a way i can fit the big ipad views on the iPhone screen in some manner but still keeping the apple reviewers happy)
There's no shortcut here - you'll have to redesign the views to fit on a smaller resolution screen, and then create a separate App Delegate and select correct XIBs at runtime.
I thought I read/saw/heard something saying that apps built for iPhone 4's Retina Display would automatically run at 640x960 when installed on an iPad. However, can't find any documentation on that specific feature, and my app still runs at 320x480 when installed on an iPad.
Is there a step I've missed to make this happen? Or did I just imagine this being a feature?
Apps do not auto-upscale, BUT if you have an image larger than the UIImageView you are placing it in, you will get as large a version as the iPad can draw.
I don't think it knows to pull in #2x images, just ones that are actually larger than the space you are placing them into.
This is not the case; currently, apps won't auto-upscale on an iPad. Perhaps Apple will add this in iOS 4.x for iPad, but certainly there's been no indication from them that they will.
