I'd like to upgrade my iPhone-only app to Universal. So, from the targets' general window I switch from iPhone to Universal and select "copy" for generate iPad Storyboard based on the iphone one. Now a new folder named iPad is created but is empty and I can't find all of the -ipad classes. What I want is to have all of the original (iPhone) classes duplicated with the -ipad suffix and a iPad dedicated Storyboad. Starting from these classes, and from the iPhone logic I want create step by step a new ipad version. In the targets' general windows ipad main interface is main_iphone-ipad but in the project doesn't exist, in the folder neither.
This isn't an issue with Xcode, thats what its supposed to do.
You can certainly duplicate your entire project for the iPad version manually if you'd like, but I can't think of a case where you'd actually want to do this.
Most of the time you just want to change the View layer between the iPad and iPhone version. You can load a different Nib based on the device you'd like or even load completely different view controllers doing simple logic like
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
viewController = [[MyViewController alloc] initWithNibName:#"ipadNIB" bundle:nil];
} else {
viewController = [[MyViewController alloc] initWithNibName:#"iphoneNIB" bundle:nil];
}
** BEGIN EDIT **
To setup a different storyboard for iPhone/iPad all you need to do is create another storyboard and name it "myprojectname_ipad.storyboard" then in the Info.plist for your project add a key called "Main storyboard file base name (iPad)" with a value "myprojectname_ipad"
** END EDIT **

I'm brand new in Xcode and have been able to scoot by with some fairly simple apps thanks to my previous programming experience, the Storyboard in Xcode, and most of all THIS WEBSITE.
One thing I haven't been able to figure out is how to make my app universal? The way I have my app set up is that it looks a lot like the iPhone home screen with pages and app icons. However, when I hit the little "Change to iPhone 5" button, 1) It only changes my FirstViewController and 2)My icons are all out of alignment.
Do I make another storyboard (If so, how?)? Do I make another view controller for each screen resolution? For either of those questions do I program a test to see which device I'm using and for it to choose the correct storyboard or ViewController? My app is currently set to universal, but I still haven't even been able to find the iPad resolution option for view controllers and stuff.
Please be as simplistic as you can. I have only been doing this for an extremely short time. Thanks for all your help both here and around this site!
So In order to get the iPad version working, follow these steps:
First go to your target settings, scroll down to "Deployment Info", and change it from iPhone to Universal
Next you will need to create a new Storyboard file. On the bar at the top go File>New>File and this thing should pop up:
After you have selected iOS>User Interface>Storyboard as shown above, click next and it will ask iPhone or iPad. After selecting iPad, the new file will be ready to map your interface for iPad. However, you need to make sure the app uses it. So go back to your target settings and scroll back down to "Deployment Info" and switch to iPad:
Set the "Main Interface" option to the name of your new storyboard file.
As for preparing for iPhone 5, that part can get a bit annoying. I find that the additional space is too small for any major additions but too large to be ignored easily. How you deal with it will vary greatly depending on what you app does. From what you described, with app icons like the iPhone screen, you will probably want to have an additional row of icons, just like the iOS. To do this, you can either manage it programatically or you may want to have seperate storyboards for iPhone 4 vs iPhone 5. If you want the separate storyboards, this question will have your solution.
To initialize storyboard:
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;
UIViewController *initialViewController;
if (iOSDeviceScreenSize.height == 480)
{
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone35
UIStoryboard *iPhone35Storyboard = [UIStoryboard storyboardWithName:#"iPhone4" bundle:nil];
// Instantiate the initial view controller object from the storyboard
initialViewController = [iPhone35Storyboard instantiateInitialViewController];
}
if (iOSDeviceScreenSize.height == 568)
{
// iPhone 5 and iPod Touch 5th generation: 4 inch screen
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4
UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:#"iPhone5" bundle:nil];
initialViewController = [iPhone4Storyboard instantiateInitialViewController];
}
self.window.rootViewController = initialViewController;
[self.window makeKeyAndVisible];
return YES;
I have a project that was intended to be an iPhone app in first instance, but now I want it to also support iPad. I have changed project's target from iPhone to Universal, but I dont know how to manage both nib versions I need now, already having nibs designed for iPhone. I tried by loading same viewControllers with different nibs according to the device, but Im not allowed to set more than one interface control to the same outlets. Any help? I have Xcode 4.4
It's pretty easy.
For your storyboard files, just include the _iPad and _iPhone suffixes.
For example, if the original storyboard name is MyStoryboard.storyboard, you'll now have MyStoryboard_iPad.storyboard and MyStoryboard_iPhone.storyboard. You can also set the storyboard file for each device under the summary view of the project.
Then, for the.xib files, include the ~iPhone and ~iPad suffixes.
ViewController.xib becomes ViewController~iPad.xib and ViewController~iPhone.xib
To start off, you can just create a duplicate if your existing .xib files and rename them to have the iPad and iPhone suffixes. Then alter the contents of each .xib as needed.
As for the .m code, you can check device type and branch your code. My approach is to define macros that identify device type, like this:
#define isDeviceIPad (UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
#define isDeviceIPhone (UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
Then I just use these macros(which return bool values) to write code that's specific to a device type(such as placement or dimensions of a particular view etc.).
You can change only targeted device as iPhone / iPad and you can use the .xib file of iPad:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
//For navigate to iphone view
}
else{
//For navigate to ipad view
}
Reference
Add 1 more XiB targeted for iPad to each file and during Navigation, select the Xib after checking Device type with the code shown above
I have an existing iPad - Application, no I want to make an universal App.
There are many Tutorials with making iPhone Apps universall, but i dont find how to make iPad apps Universal. Is there somebody having experienxce with this?
No Storyboards are used, yust normal xib.
I've readed this tutorial, and porting iPhone apps to universal seems to be better supported by xcode:
http://www.raywenderlich.com/1111/how-to-port-an-iphone-application-to-the-ipad
I would think that the basic idea would be the same, whether you were converting an iPhone app to a universal app, or an iPad app to a universal one(?)
Set the iOS application target to "Universal".
If a view controller, say, XYZViewController has an associated xib for its UI, then - when you create a xib for the iPhone interface - append ~iphone to the name of the iPhone interface and ~ipad to the iPad one, i.e. their file names are
XYZViewController~iphone.xib and XYZViewController~ipad.xib. That way the right xib will be picked up if you pass nil or #"XYZViewController" as nib name to the designated initializer for the view controller. (It's worth noting that the same IBOutlet can be hooked up to the corresponding UI elements in both xibs simultaneously.)
In code, whenever you need to use a different display metaphor that depends on the device type (say you want to use , check for the device type through the test
if ([UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{ ... } else { ... }
Another place where you might want to use this test is in VC's shouldautorotatetointerfaceorientation: method.
I have a newbie question about integrating two iOS apps. I have created an app in iOS 5 (my first app so I dont have any knowledge of iOS 4 except the fact thah there were xibs files instead of storyboard and also ARC was not included).
Now I have to include one older standalone app (built for iOS 4 with xibs and non ARC) to my iOS 5 app. Lets say that in my app on Main menu view there will be a new button opening the main menu of the other app.
So I did some research and find out how to disable ARC by the fno-objc-arc flag. Fine, now I have imported all the files of the second app to mine app and all the classes have the flag set.
I can still run my app without problem.
Now I have no idea how to let my new button to open the mainViewController of the old app - this app has MainWindow.xib (contains a window and one navigation controller). This MainWindow is set to be Main Interface in the old project. There are also some init call in appMainDelegate file. Where can I call them in my app?
Could anybody tell me what needs to be done. I have an idea, that I will add only one new UIViewController to my storyboard. This will be the starting point for the old app and than everything will work as it used to. Or will I have to create more controllers (for every xib) in my storyboard? This is where I dont know what to do. Any help much appriciated. thank you
Try doing something like the following, anything like it or simmular should work:
In the method of the button (the one you call your new button) have it execute the following code:
OldAppMainViewController *controller = [[OldAppMainViewController alloc] init];
//Here you can assign vallues to any properties that you might want to
[self.navigationController pushViewController:controller animated:YES];
That old apps main view controller should have a init with nub named function so it should work. If this does not work try something along the lines of:
OldAppMainViewController *controller = [[OldAppMainViewController alloc] initWithNibName:#"OldAppMainViewController" bundle:nil];
Where the NIB name is the .xib file name without the extension.
Also make sure that all connections in interface builder is setup correctly
I have an iPhone app with
FirstViewController and SecondViewController with respective views FirstView.xib and SecondView.xib.
Now I want to make this app work with both iPhone and iPad. For iPad I need to merge Firstview.xib and SecondView.xib into a single ThirdView-iPad.xib.
What would be the best approach? Do I need to write another ViewController class for iPad or can I use existing FirstViewController and SecondViewController with single xib?
My research so far says that there is no way to use multiple ViewControllers with single xib. Please let me know the best way to do this.
Thanks
if you are using Xcode4 you can use "transition to universal target" and it will do everything needed
http://xcodebook.com/2011/05/making-an-ios-target-universal/
if you dont have it then I recommend to keep controllers out of your xib. xib files will be only containing views for iphone and ipad but the controllers "can" be same. and you can control your logic from the rootviewcontroller, just an idea..it all depends on your project.
You would be best of to just create a new ViewController unless you're into masochism. Reusing in that way would most likely be to much trouble, and I'd go with aggregation or inheritance in the case you need to reuse logic in your ViewControllers.
I typically create a base ViewController, say XYZViewController and then create a XYZViewController_iPhone with all iPhone-specials and a separate XYZViewController_iPad for iPads. But if they're totally different I give them unique names and their own NIBs as well as ViewControllers.
There Are following Rules To Convert The Iphone App to Univarsal App
1) In Plist File Add NSMainNibFile~ipad .... MainWindow_ipad(ipad window).
2) Implement separate Names Xibs (Iphone & ipad)
3)in Target Targeted Device Family set to (iphone/ipad)
and set The Frames According To Ipad &iphone
For example
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
{
btnHme.frame=CGRectMake(971,6, 32, 32); //ipad
}
else
{
btnHme.frame=CGRectMake(438,6, 32, 32); //iphone
}
