I'm just starting out with iOS development and I'm actually trying to make an iPad application. I've found a sample project that is perfect for me to start from but it's meant as an iPhone app.
So I was wondering, maybe it's just a matter of replacing some xml file to convert it into an iPad app?
Any ideas if it can be done, and how?
If you are using Xcode 4, select the application target and change the value of Devices in the Summary tab to iPad.
You should also modify the appropriate xib files made for iPhone. You may also have to change any code that works only for the iPhone like specifying frames with fixes values that fit the iPhone screen size, but are too small for the iPad screen size.

I have applied the required settings for converting my iPhone app to run on iPad. So, when i Build and Run, the window is an iPad window but the size is not compatible, meaning that no proper scaling has taken place.
Moreover, the xib files formed inside the iPad resources still show iPhone window. Please suggest where I am wrong
This might be a repeat question.But i have a problem. I have an iPad app functional. The app is built in iOS 6. When i started building it i chose iPad as targeted device NOT universal. Now my client has asked for an iPhone version of it.In my iPad app i keep adding custom views as the client clicks "Add More".I add a custom view which is bunch of textfields, buttons etc.So i copied my iPad app and changed the Targeted device family to iPhone once and also Universal next time and tested it. So when i launch the app in iPhone configuration (keeping the targeted device family as Universal) my view controller stays like that on iPad. I cannot scroll the app also(not up/down..nor sideways). Is this the correct way to convert iPad app to iPhone app . Also everything is still with scale to iPad. Should i start a new project and start everything from scratch.Set the storyboard to fit according to iPhone configuration? In my research people said just change the targeted device family to Universal. But it doesn't work. Please let me know if you need more information. Thanks.
It is possible to convert the current project you have to an app that can be used universally, but it would take more time than simply just creating a new project that allows universal usage, and adding in the files of which you used for your iPad project.
Hint: You can use more than one storyboard when the project was created universally. It will automatically set this up for you.
I would also advise that you separate your files into what works universally, and what is specific for the iPhone or the iPad.
Happy Coding!
After many search i found that it possible to have an application for both Iphone and ipad devices.but in your code you should define unique ui for each device(two xib file).
It is my understanding (i have seen it) that some apps can be opened and viewed in an iPad. Although, the iPad keeps the screen small, or pixelated if doubled the screen size.
I am attempting to do the same thing with my app, however when I attempt to run it on an iPad it crashes with the error
'Could not find a storyboard named 'MainStoryboard_iPad'
This is obvious, as I do no have a storyboard for the iPad, but currently I don't want one. I just want the iPad to run the app as an iPhone app in a smaller version. So my question is, how do I stop it from looking for the iPad storyboard? Its my understanding I must adjust something in the plist.info but I don't know how to access that in xcode. its my understanding you select the project in the navigator then select 'info' but I don't see any information that people say should be in the plist.info.
Thanks
You seem to have made your application universal. You want to set your "devices" to iPhone. This can be done on the target summary page (No need to interact with your .plist directly).
Only target iPhone platform, and do not call any iPad interface objects in your code. You should look in your Main xib file to make sure there are no references to an iPad interface object.
iPhone only apps should natively run in double-pixel mode. In order to resolve the pixelated / grainy issue you see, use #2x (for iPhone) size images. This will reduce the pixelation you see, but will still contain some.
Ok, I found the final issue. After editing the summary to 'iPhone' I also had to go into the Info tab and change the line that says
'Main storyboard file base name (iPad) to MainStoryboard_iPhone. It was currently set to MainStoryboard_iPad. That second step fixed the issue.
Thanks guys!
I had created an iPhone app long time back. Now I want to kind of convert the same into an iPad app (the code would more or less remain the same, I only want to redesign the xib for iPad size).
Now I am using XCode 4 and after opening the app, I changed the devices to iPad. But my .xib are still showing iPhone size.
It created an iPad folder (just like Classes/Resources/Products...).
Also to add, the app now opens an iPad simulator, but let's say I have a UIWebView which just stretches to iPhone size (as in IB) and not the complete iPad size...
How and where do I redesign the xib for iPad ? What are the updates to be made when we just change the devices from iPhone to iPad ? Also I guess an iPhone app would work on iPad (using 2x), but the reverse is not true.
You should look into creating a Universal app which basically has shared code and libraries for the iPhone and iPad but different view layers (views or XIBs).
In that model you have different interfaces for both which you should. The paradigms are different - in iPhone you have small real estate so you have navigators that drill in and pop out. In iPad, you have more real estate so you have master/detail splitter views with pop-over controls. As you pointed out, even the web views are different sizes at a minimum.
If you start fresh you can create a universal app and get a feel for how it's laid out. File, new project, iOS, pick app type, next. For device family select Universal.
If you are converting, there's some resources out there. Here's some:

How to convert iPhone app to universal in xcode4, if I previously converted, but deleted MainWindow-iPad?
Convert simple iPhone app to Universal app
I find it easiest to open the xibs in the separate Interface Builder that came with previous (3.2?) XCode and use its "convert to iPad using autoresize masks" option. Then I include the new separate XIBS in the project and do conditional loading (eg - use the UI_USER_INTERFACE_IDIOM() makro to load one xib or another.)
I have very simple iPhone app, which uses just UIButtons, UIlabels, UITableView. without any custom controllers and graphics. How can I convert app to universal with that UI?
First update the application target device to Universal.
Update the application target device to Universal.
Check the Info.plist for NSMainNibFile & NSMainNibFile~ipad keys.
For all other views, have two different NIB. For example FirstView.xib & FirstView~ipad.xib. iOS runtime will load the proper view based on the device.
Here is a screenshot of a sample project:
I needed to convert my iPhone App to iPad yesterday and found the easiest way to do it as long as your app is pretty simple. Mine was literally just some tableViews that were set to auto-size. In Targets / Devices just change it from 'iPhone' to 'Universal' and then build your application. This worked very nicely for me. All tableViews were perfectly formatted for the iPad and that is really all I needed.
Note that if you had any other XIB files that were not just tableViews, such as a window with text fields, all you have to do is set them each to resize properly so they stretch and stay at the top and your simple app should be pretty much all set for the iPad.
Obviously you'll need to test it and tweak anything needed but for the most part the above worked magically for me and took literally one second to convert my iPhone app to an iPad app!
