Cordova plugin, with native storyboard UI - ios

I am in the midst of creating a Cordova camera plugin. I know there are many alternatives out there, but none of them have all of the functionality that I am looking for, or they are outdated.
So I have been working with the AVCam-iOSUsingAVFoundationtoCaptureImagesandMovies project that Apple provides to get you started with their AVFoundation library.
After working with the library a bit, I realized that I wanted to make it into a Cordova plugin, but the only thing that I am concerned about is the UI functionality of the plugin. So I am wondering if it is possible to include the storyboard files (that render the view / buttons) in the Plugin, so that they work seamlessly, or if it needs to be programmatically created, like other Camera plugins (like CameraPreview) do.

Yeah, you can add a storyboard to a plugin.
First add the storyboard in the plugin.xml
<resource-file src="src/ios/YourStoryboard.storyboard"/>
Then in the code you can get the initial view controller like this:
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"storyboardName" bundle:nil];
UIViewController * vc = [sb instantiateInitialViewController];

Integrating one iOS project into another iOS project [duplicate]

This question already has answers here:
importing one Xcode project into another
(2 answers)
Closed 6 years ago.
I have one existing project. Now i have developed one project with some new feature. Need to integrate the existing project to this. When i run this project it shows this app functionalities. On that one button click to show the existing project home page and continue that existing project. I need to enter the existing project and use that functionalities and UI whatever and exit from that to continue the current project. Kindly give me solution. If you don't know requirement ping me i will explain with detail.
You can possibly add the project folder of your project to your existing project and then once you are in your existing project on the click of your button you can do this,
UIStoryboard *sb = [UIStoryboard stoaryboardWithName:#"Main" bundle:nil];
This will load the storyboard of your new project, if you have made the project using xib then you can load the xib as well
Then you can,
ViewController *firstController= [sb instantiateViewControllerWithIdentifier:#"firstController"];
This will load the view controller of your new project, then you can do this to present this view controller,
[self.viewController presentViewController:firstController animated:YES completion:nil];
This will load your view controller now you can do what you want in your new project.
To comeback to your existing project you can set your new project delegate to be your old project and implement methods to comeback.
Hope this helps.

STORYBOARD EXCEPTION - Storyboard doesn't contain a view controller with identifier

I am currently developing an iOS application for both iPhone and iPad. I'm trying to show a NavigationController to make a module that shows files. In an iPhone it works just fine, but I can´t get it to work in iPad.
I'm getting the following error:
'Storyboard (<UIStoryboard: 0x919b200>) doesn't contain a view controller with identifier 'FilesNavigation''
and this is the code:
case 10: // Files
{
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"FilesNavigation"];
FilesViewController *filesViewController = [storyboard instantiateViewControllerWithIdentifier:#"Files"];
[navigationController pushViewController:filesViewController animated:YES];
self.slidingViewController.topViewController = navigationController;
break;
}
And in my storyboard I have already set the Storyboard ID for the navigation controller.
>##Custom Class
>Class: UINavigationController
>##Identity
>Storyboard ID: FilesNavigation
I used this code for another case on the switch/case block for other module and it works for iPad too, its the first time that I have this error.
I figured it out, the problem was that the Storyboard wasn't updating in the device.
Uninstall the app from the simulator/iPhone/iPad
Product > Clean
Build & Run
As stated in #T0m_Twt's answer in this question
In the right pane, in the identity inspector section give a storyboard Id to your Navigation Controller.
I took a screenshot for you
Here's another case:
There are two localized storyboards. Only one of them has the view controller you want.
By chance, do you have a storyboard for iPhone and a different one for iPad? If you do, then the iPad one might not have a storyboard with that identifier. Also when running on an iPad, set a break point in your code and verify what your "storyboard" object is.
I use a category on UIStoryboard that will give me the storyboards for each platform.
I can use [UIStoryboard storyboardHome] and that will determine if it needs iPad or iPhone specific and return that to me. I also ensure my storyboards follow proper naming. So I would have Home_iPad and Home_iPhone.
TL;DR - clear everything and remove old version of the app as well, if there's any.
It may sound crazy, but suppose that if you have changed target name which changed bundle name as well, you might have both the old and new version of the app installed in the simulator / device, and this might cause trouble for the UIStoryboard instance failed to instantiate some view controllers, which might eventually cause the trouble described in the question. To solve it, you need to remove all related apps or simply reset the simulator / device.

Base Internalization without storyboard in XCode 5.0

I prefer not to work with Storyboard, so my projects start from an empty project, then in the appDelegate I write code like this:
MyViewController *VC = [[MyViewController alloc]init];
self.window.rootViewController = VC;
This intro just to tell you that if I try to activate Base Internationalization and I load the controller in that way I obtain just an empty controller. The xib seems not to be loaded.
Let's say that I want just to setup my project to be multi-language in the next future. So I don't add further languages, I keep only English.
These are the steps that I do to activate the Base Internat.
Selecting the xib file and pushing "Localize"
Localize it for the only Language available, English
From "Project" -> tab "info" I select "Use base Internationalization", selecting the only xib available.
Back to the xib, I activate the localizable string for English language (at the moment in the "Localization Box" of the xib I see "base" and "english". Eventually I add a Label to the xib.. just to be sure that the strings file will be created correctly.
Now, if I launch the App.... the xib isn't correctly loaded!
I hate this situation because it would be great to have this project setup for future translations... but it seems to work only if I work with a Storyboard.
Do you have some suggestions or have you experienced something similar with your projects?

Storyboard UI testing from code

I have an iOS app and I want to test its UI from code (with unit-test). I want to imitate a user's activity and storyboard activity: tap on button, tap on barbutton, write to textfield, perform segue.
I have problem with seques. I have a TableViewConrtoller in a NavigationController. Firstly, how can i reach the TableViewController from code?
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard_iPhone" bundle:nil];
UINavigationController *nav = [storyboard instantiateInitialViewController];
GoodHabitsViewController *good = [nav.viewControllers objectAtIndex:0];
NSLog(#"%#", good.addButton.title);
[good performSegueWithIdentifier:#"AddGoodHabitSegue" sender:good];
NSLog write correct value, the button's title is "add", and "add" appears in log.
But after the performSequeWithIdentifier the following warning appears:
Warning: Attempt to present <AddGoodHabitViewController: 0x74c8310> on <UINavigationController: 0x764e120> whose view is not in the window hierarchy!
How can I perform the seque, how can I push addButton (UIBarButton) and how can I make reference to AddGoodHabitViewController (where the segue point).
There are two varieties of tests that can be run on the OCUnit platform - so called "application" tests, and so-called "logic" tests.
Only "application" tests allow you to exercise UIViewControllers, UIViews and so forth. If you specified "create test target" when you created the project, it will use the "application" style. Otherwise adding a teset target later, by default, uses the "logic" style. To covert an existing test target to use "application" tests, TwoBit Labs have a nice: guide
Another way to exercise code all the way up to the view controller and views is to use the Cedar BDD test framework. Cedar tests are run inside of an iOS application, so besides being able to test ViewControllers and Views, its also possible to test on either device or simulator.
UIAutomation allows the execution of automated functional tests, by driving the UI itself (as opposed to exercising UI code). The problem I have with UIAutomation is that, as far as I know, its not possible to execute it from the cmd-line, making it hard to include in an automated test suite - one that would be run by a continuous integration server. . . . someone might come up with a work-around for this using Automator.app or similar, but so far nobody has.
Calabash is another great UI testing framework, and can be run from the cmd-line, so doesn't suffer from the limitations I described above, wrt UIAutomation.
Bear in mind that automated functional testing, and testing UIViewControllers and Views at the code-level are two very different things. The latter certainly has value, and simply requires setting up the bundle loaders correctly.
Update: With recent versions of Xcode 5+, application-style tests are the default.
As the error message points out, the problem is that you're trying to present on a UIViewController whose view is not in the UIWindow hierarchy.
The easiest way to fix it:
- (void)testExample {
//
// Arrange
// Storyboard
//
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
//
// Arrange
// View Controller
//
UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:#"ViewController"];
[UIApplication sharedApplication].keyWindow.rootViewController = viewController;
//
// Act
//
[viewController performSegueWithIdentifier:#"ModalSegue" sender:nil];
//
// Assert
//
XCTAssertEqualObjects(viewController.presentedViewController.title, #"Second");
}
Unit tests (i.e. those you get when adding unit tests to a project via the Xcode template) are not for testing your UI. You need to look at UI Automation which allows you to code up UI actions using JavaScript.
Check out KIF. It sounds like pretty much what you need:
https://github.com/kif-framework/KIF
It's an Objective-C based UI Testing framework that integrates with the Accessibility framework built in to the app (as UI Automation does).
Or follow this tutorial to ensure it is what you want:

Hope you find your solution!

Generating a view programmatically in iOS

Update:
Thanks for all the tips, everyone. The tutorial mentions that a XIB file is provided (which I don't have) so I'm doing something wrong in how I'm creating the the project.
I am following Apple's Core Data Tutorial for iOS. This tutorial has not been updated for ARC—apparently for Xcode 4, since it asks to "create a new project using the Window-Based Application template in the iOS section."
Since that option doesn't exist under Xcode 4.4.1, I looked around Stack Overflow and read that I should create an empty application. As per the tutorial instructions, I created no Storyboard or NIB file.
Other than updating the code for ARC (using strong in place of retain and not implementing the provided dealloc method), I'm confident that the code in my project matches that of the tutorial up to the end of the chapter "The Table View Controller." At this point, the tutorial says I should be able to run the project and get a view.
Instead, I get a blank, black screen.
Maybe my problem is too vague to solve here, but should I perhaps be using a different project template? Which one?
I have only two classes: a RootViewController and an AppDelegate. AppDelegate imports RootViewController and contains a UIWindow property. Again, there is no Storyboard or NIB in the project.
I can provide any code too if there's someplace specific to look.
If you want to check if your setup is correct do the following:
add a background color to your window
self.window.backgroundColor = [UIColor whiteColor];
make sure you tell the window to display itself
[self.window makeKeyAndVisible];
make sure your view controller is the window's rootViewController
self.window.rootViewController = myViewControllerInstance;
Choose Single View Application, and uncheck 'Use storyboards" field. The rest should go the same.
