I am having an iPhone application and i want to make it compatible with iPad so what i did is that I went to project->Target->Right Click->Duplicate->Duplicate and Transition to iPad so i got nib files for iPad, i set the views according to iPad resolution. So my this app is working on iPad as well as iPhone my question is that i am having two targets in my project and i have to build two separate builds for iPhone and iPad. I think it is not universal app is it? If it is or not should i have to have separate App ID for iPhone and iPad application to put it on App store ? Thanks
I don't know much about the publishing on the App Store part, but in the company where I work each time we make an universal app for a client we have just one target, one project and one ipa.
Based on the device's type (iPad or iPhone) we then load different files and/or nibs.
For example, if you select your target, you have the Universal option for the Devices field. Choosing it lets you specify different interfaces for each device. The we load different module for each device or use general modules with different nibs.

We know that in monotouch we have 2 solution for developing a project for both iPhone and iPads.
First is using Montouch iPad Application projects for iPad, and Monotouch iPhone Application projects for iPhone and create two separate project for each of them.
Another solution is using one Universal Projects for both o them.
The question is: what solution is better and with witch one the result has more quality?
Pros and cons of Universal app.
Pros:
One place to fix bugs in app's business logic;
Convenient to users (after install on one device it could be automatically installed on other device);
Marketing costs could be half as much;
Cons:
It could be too many if -blocks, which are checks for UIDevice.CurrentDevice.UserInterfaceIdiom;
Bigger app size;
Some of the features (mostly in games) do not fit well on iPhone's display.
If you used XIB-based interfaces, you must make separated XIB for iPad OR update XIB content layout in UIViewController's ViewWillAppear event (in which iOS updates View frame according to display size);
If your app is not free, you couldn't release "HD version" with bigger price.
Basically, universal app is better for users, but harder for developers and designers.
I think, you are asking about iPhone and iPad. Because, universal app includes iPhone and iPad (not iPhone and iPod).
So considering this:
You should go with Universal app because of below reason:
1) There will be one source file of the app which will work in both iPhone and iPad.
2) If user has both devices (iPhone and iPad), then they get a single copy of the app and can install in both devices.
3) Your app supports both devices, so users will be highly attract and download your app quickly.
4) If your app will more downloaded (because of Universal app) then there are chances that, your app comes into "New and WhatWorthy" section and even "Feature" section of the apple.
There can be main reason why we should go for Universal app instead of separate app for iPhone and iPad.
Hope, you got an idea.
Cheers!
I need to develop some app for iPad and iPhone users.
I understand that there are 3 ways:
Two distinct Apps, one for iPhone and one for iPad. (Not linked in apple store)
One Universal app (appear with + sign in Apple Store, the app store choose the desired app depending on the device) (I choose from xcode to make the app Universal).
One application with two targets, One for iPhone and one for iPad. (using Duplicate target for iPad in xcode) (Linked in apple store).
I need to understand the differences between 2 and 3 above.
Thanks.
The difference is that in 2 you are creating one single binary from one Xcode project that works on both iPad and iPhone. It has a universal target meaning it runs on both iPad and iPhone requiring you to adapt the user interface appropriately.
In 3 I believe you are implying that you create one Xcode project and create two build targets inside the project. I have done this before and it allows you to easily share files between applications. Just add references to the files you want to share in both targets. As far as how 3 looks in the AppStore it looks the same as 1, two separate applications.
I have an iPhone application and I want to run it on the iPad in normal mode (not in the mini small emulation mode)
How do I compile my program to show up in full screen mode?
Any easy tutorial?
You want to refactor you current iPhone only app in to a Universal app.
iPhone SDK 3.2 [and later] supports the
development of Universal applications.
A Universal app is optimized to run on
all iPhone OS devices—itʼs essentially
an iPhone app and an iPad app built as
a single binary.
More details can be found in the Introducing Universal Applications for iPhone OS documentation.
In order to achieve your design goals
for a Universal application, you will
need to use conditional coding to
determine the availability of features
when your app is running. Conditional
coding allows you to make sure youʼre
loading the right resources, using
functionality thatʼs supported by the
device and properly leveraging
hardware thatʼs available.
In Xcode 4 you can set the device type, be sure to create iPad specific UI for you app.
Once you select Universal xcode will try and help you out by creating some interface-bilder files.
The iPhone views are created with the size 480×320px in case of pre-iphone 4, and the iphone 4 has 960x480px. The iPad has 1024x768, so you need to change the views for that size. There's no automatic way of doing it. In Xcode 4 you have some sort of "change this view to ipad", but the position of the elements in the view, but you will have to do some tunning on the final views, because the ipad UI of an App should give a different UX than the iPhone.
I am creating an app which has version for both iPhone and iPad, iPad version has different GUI and some more functionality. Currently, I separate them in 2 projects.
After reading this article: Jump from iphone to ipad development...
And see:
"All iPad users who have already downloaded your free or paid App to their iPhone or iPod Touch will be able to download your iPhone App – only if you have updated your binary submission to the App store to make your iPhone App compatible with iPad. If you do not update and create the separate binaries, then you are potentially losing out. Using the new SDK you will be able to create a single binary which will install one version of your app when used on the iPhone or iPod Touch and a different binary when installed on an iPad"
I don't know if my current way is correct when separate them in 2 different apps! and how to create single binary which will install one version of your app when used on the iPhone or iPod Touch and a different binary when installed on an iPad?
Does anyone know about this please help me!
There are two ways to have an app on both iPhone and iPad. One is to build two separate apps that do the same thing. This is what you are doing, but not what you described. It creates two applications, one for iPhone and one for iPad, that do the same thing. As such, purchasing one will not give the user access to the other.
If you want the user to be able to use a single app on both the iPhone and iPad with different interfaces, you need to build a universal app. It will contain code and resources for both the iPhone and iPad. See iOS Application Programming Guide: Build-Time Configuration Details. About two thirds of the way down is a section on universal applications.
Edit: I found another document specifically about universal applications: http://devimages.apple.com/iphone/resources/introductiontouniversalapps.pdf
Whether to have two separate SKUs on the App Store or not is usually more of a business question than a technical one. Separate apps lets you segment your users and charge more for the iPad version. On the other hand a universal app is usually better received by users and can make the most sense if what you have is a premium, 'expensive' niche app.
If you want to go the universal route:
If you have an iPhone application that
you want to upgrade to run on iPad
devices you need to upgrade the target
that builds your iPhone application
into a target that can build both an
iPhone and an iPad application, or add
a target to your project for building
the iPad application.
To upgrade an iPhone target for iPad
development, select the target in the
Groups & Files list and choose Project / Upgrade Current Target for iPad.
I am new to iPad,I am having iPhone distribution build, can i upload to apple for iPad Device?Will it run? will it be accepted by Apple?otherwise i have to create new Ipad application for existing iphone application?
Practically all iPhone apps will run unmodified on the iPad. They will simply be scaled up pixel-by-pixel (with a little "2x" button so the user can choose scaled/unscaled mode).
For the best user experience, you should create a universal binary that provides customised behaviour for each platform, but this isn't required.
Any iPhone application, an application that has not been optimized for the iPad, will run on the iPad in 'compatibility mode', which means it will get its own iPhone-sized frame in the center of the iPad screen. The user also has the option to zoom in the application 2 times, so it takes up almost the entire iPad screen.
So if you want your app to run at all on the iPad, you don't have to do anything exciting, just submit it to Apple as usual, and iPad users will be able to download and use it.
If you want to optimize your application for the iPad, which is almost always preferred over 'compatibility mode', you can either make your current application into a Universal one, which is an app which contains both iPhone and iPad versions, in one binary, or you can create two different applications, one for the iPhone and one for the iPad. You can find more information on this on the Apple Developer website.
