I've created full app for iPhone, but I need to make iPad version. mostly the app is lists, but login screen, logo and cells are too small (just to repeat - it was created for iPhone). Is there any way to create iPad user interface or stretch phone views?
Thatnks for your help. Btw sorry if it's duplicate of some similar question. Just couldn't find it (maybe bad keywords).
You absolutely should have separate XIBs for iPad & iPhone. Now, if you want to try and save some work and start from the iPhone XIBs as your base point, you should take a look at the top two answers from this question:
Xcode 4 .xib Create iPad Version

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'm a newbie of iOS development and I'm confused regarding universal app.
We can use the same code, same xib file for iPhone 4(retina) and previous iPhones, but why we should write two different xibs for iPhone and iPad? What's the difference?
For iPhone and retina iPhone, we use "point" instead of pixel for the coordinate. Why we can't use the similar method for iPhone and iPad?
For some simple apps, it is possible to design your iPhone UI and reuse the same xib file for the iPad. Just select your Target in XCode and copy the Main Interface text from iPhone / iPod Deployment Info to iPad Deployment Info. If you're using a Main Storyboard, copy that too. However, the iPad does not simply scale everything up from the 320*480 / 640*960 iPhone screen to the 768*1024 / 1536*2048 iPad screen. #elgarva correctly says that this would look terrible. Instead, the iPad version makes use of your autosizing masks to resize or reposition each view.
If all of your views can be considered to be left-middle-right or top-middle-bottom, this may work. If you have anything more complicated, you'll need to design a separate iPad interface.
Duplicating your iPhone UI is not just discouraged for aesthetic reasons - iPhones often end up containing a deep and confusing navigation tree for tasks that the iPad can fit on a single screen.
The main reason, is that if you just scale the elements on the UI to fit the larger screen, it wouldn't look nice... and you don't need to do anything for it to work, it automatically does it for you if your app is iPhone only and installed on an iPad (if the user chooses to).
Having a different XIB lets you rearrange your app, and think it so that you can take advantage of the larger screen. You can probably show more information on one iPad view than on 3 different screens on the iPhone... so, your iPhone app could show basic info and expand it when the user taps on it, while your iPad version could show all the information on load, plus extra graphics that look nice but aren't needed, and wouldn't make sense on the iPhone screen.
PS: If you're starting a new app, I strongly suggest you using the storyboard if your app won't have a lot of views... it's really easy to get started and it lets you see your app flow at a glance.
The ratina display just doubles the resolution of original iPhone. If you don't provide separate graphics for retina display, then system just doubles the resolution of resources.
The points are related to physical size of screen, which is similar in old and new iPhones.
For iPads, the screen size changes. This means that its dimension in points will be different from that of iPhone.
duplicating the xib file and renaming that as filename~ipad.xib is working great for me in ios6.1
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!
