I'm developing 2 iOS apps; a iPhone app and an iPad app. Both have different purposes and functions, but I'd like to (once it's complete) embed the iPhone views into the iPad app as a preview.
(in the iPad app) I have a tab view controller, it loads various controllers and the last one will be a Preview. I'd use half (landscape mode) of the screen for some final settings and the other half to preview what will be produced.
My questions are:
Is this doable?
Is it allowed by Apple?
I've seen other discussions where people want to embed other, App Store apps from other developers. I'm not trying to do this; I only intend to embed the app I have the code for.
I'm just not sure the direction to look in to get this answer.
You should put both of them in the same project, and use a simple iPhone/iPad in AppDelegate.m to start the app with the appropriate View Controller.
That way you can present the iPhone app within iPad app by simply showing a view controller. Apple won't reject since technically it's still only 1 app.
To produce and submit 2 apps from the same project, create another Target. You can set bundle identifier / device type / etc per Target.

When I first started to create my app, I thought that using launch screens would be a good idea, so I added the LaunchScreen.storyboard file and created a view controller meant to be the launch screen.
Now, however, I would like to remove this launch screen now. I have tried to delete the view controller and the file itself, which does not work, as the launch screen view controller still appears somehow. I have tried this answer, but nothing changed. I tried another answer(can't remember the link) which told me to delete a key-value pair in the project info. After doing that, the launch screen is gone, but a black screen replaces it, and the app is not full screen anymore on iPhone 8. There are black bars on the top and bottom of the screen.
My question is: how can I remove the launch screen completely without any side effects?
Xcode 9, Swift 4
Using a Launch Screen
It’s best to use an Xcode storyboard for your launch screen, but you can provide a set of static images if necessary.
Including static images will increase the size of your binary because you must include all resolutions (see below) otherwise you will see "black screen & the app is not full screen".
Starting April 2018, all new iOS apps submitted to the App Store must be built with the iOS 11 SDK. All new apps for iPhone, including universal apps, must support the Super Retina display of iPhone X.
https://developer.apple.com/ios/submit/
So, you would be best off replacing the launch screen with a really simple view of your application (with no data).
Take at the Human Interface Guidelines for more information: https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/launch-screen/
To quote:
Design a launch screen that’s nearly identical to the first screen of your app.
Avoid including text on your launch screen.
Downplay launch
Don’t advertise.
You can do this by using the menu bar:
File >
New >
File
Once you have created your new LaunchScreen.storyboard you need to ensure it's the one assigned to the application. You can do this either through the project file explorer or through the application plist.
Using Static Images
If you are really committed to avoid using a storyboard then you can migrate to using launch images inside an asset catalog by pressing the button above the launch screen storyboard.
By migrating to launch screen images you will be required to provide all variants of screen sizes otherwise you will not support devices such as the iPhone X.
You might be required to delete the LaunchScreen.storyboard and delete the references in the project explorer / plist.
Final notes
You may be required to delete Derived Data to remove any cached version of the launch screen storyboard.
I have an application which developed before iPhone X release. My question is the following, can I add iPhoneX support for only newly created view controllers? I mean some view controllers will have iPhoneX friendly UI some not in the same app. For my new view controllers I'm using safe area but UI is broken for iPhoneX.
For the app I guess Apple will not allow partial support for iPhoneX.
Just wondering is it possible or not and how if answer is yes.
It's either all or none. If your app uses a Launch Screen storyboard and is built with a Base SDK of iOS 11 or if your app uses launch images and includes an iPhone X launch image then your whole app is presumed to work on an iPhone X. You will need to make sure all screens work correctly.
Think about what a terrible user experience it would be to use an app on an iPhone X where some views use the whole screen and some views only use part of the screen.
I'm new with iOS and yesterday i learnt about storyboard. it works great. i refer to this link. I tried to create iPhone apps with a storyboard.
But now i want to create an universal apps, that means for iPhone and iPad. but also using the storyboard. lets say if i have the same UI, that wont be an issue. Same UI means, my iPhone UI using tab bar controller, my iPad also use a tab bar controller. I just need to point to the same class, and the result will be the same. Now, i want have a different UI. my iPhone will use a tab bar, but my iPad will use a split view.
here is my question :
is that possible to do that with device target universal? i mean iPhone with tab bar, iPad with split view.
if yes, how can i know which device is running? either i choose iPad or iPhone. How can i know i run on iPhone/iPad? what should I validate in the appdelegate?
For ipad storyboard, i drag a split view controller but i can't see any master detail whenever i run the apps. how can it be like that?
thanks. :)
If you create a Universal application (an application that supports both iPhone and iPad), Xcode will by default give you two Storyboards - one for iPhone, one for iPad. Under your target's settings you'll see a place where you can configure which Storyboard presents the main interface - you can set this separately for iPhone and iPad:
The OS will take care of loading the correct Storyboard for you.
If you want to detect in code whether you're running on an iPhone or iPad, you can use USER_INTERFACE_IDIOM(). For example:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
There's also UIUserInterfaceIdiomPad for iPad.
I'm converting an iphone app to an ipad app. I've changed the project's build target from "iphone" to "ipad" and the app compiles, builds, runs and displays the way I want it to.
However, I've noticed that some parts of Storyboard still believe this is an iphone app. For example, when I try to build a segue, it only offers me the "push" "modal" and "custom" options. A newly created ipad project also offers the "popover" and "replace" options.
Similarly, this converted app does not offer me the possibility of a Split View Controller.
So is there a setting or some way to get this "iphone" -> "ipad" app to have the full ipad storyboard options without restarting the project and copying everything over?
I had a similar problem to this awhile back. I fixed it by clicking on my main project on the navigation panel. If you go to summary and look under the iOS Application Development you will see a spot that asks which devices your app is targeted to. Make sure this is switched to universal
Next create an iPad storyboard under File > new > File... > User Interface > Storyboard > set Device Family to iPad (It sounds like you already did this though). Make sure you call it something different then your iPhone storyboard.
Lastly go back to your project settings and scroll down to the iPad Development Info you will see a drop down titled Main Storyboard. Make sure that is set to your newly created iPad storyboard.
If this still is not working for you the Standford ItunesU iOS course has a lecture on converting iPhone applications to universal ones.
I have a situation causing me to have a need to support two different launch images for Portrait orientation on iPads as the views will be different depending on the IOS version.
I'm developing iPad/iPhone app that supports a UISplitViewController as the root window when the device is an iPad. In IOS 5.0, supports the master view controller being displayed in split view while in portrait mode by responding "NO" in the shouldHideViewController UISplitViewControllerDelegate method. In IOS 4.2, this method is not called and thus the Master View Controller is not displayed in Portrait orientation. Instead, it is a popover presented when a Nav button is pressed.
Is there a way to create a single version of the application (from an iTunes customer perspective) that includes the appropriate launch image based on IOS version?
The iPhone App Programming Guide within the Advanced Tips and Tricks section describes how different launch images can be specified based on platform and device, but no IOS version as so: key_root-platform~device
Another post's answer indicated that I may be able to solve a similar problem by creating multiple targets to support multiple versions. Is it possible to create multiple targets and upload them to Apple as a single application and have them distribute the appropriate binaries based on version? Any tips on how would be greatly appreciated.
No, there is no way to do what you are asking for. Your best bet is to come up with some launch image that's not trying to be a faithful reproduction of what your home screen is.
Could you not just show the split view with the popover/sidebar closed in landscape view? That way it will look much the same for iOS4 and iO5.
I think you can accomplish this by creating a custom splash screen. Then you can perform a runtime check and load the appropriate image based on the iOS version. I have seen custom splash screens before (eg animated splash screens).
I think you would overide startupImageWithOrientation:, see this post more for info.
As for your question about having multiple targets be one app, the answer is no.
