I'm working on an IOS swift application that will allow the user to record the entire screen, any app and even the home screen.
In order to do that, I added a Broadcast Upload Extension to my app.
First I used the RPSystemBroadcastPickerView class in order to add a record button to my view that allow the user to open the record popup and select to which app he wants to broadcast the screen flow. And it's working fine :
But I would like to avoid this step and directly open the popup when the app launch.
So I wrote the following code to do that :
RPBroadcastActivityViewController.load(withPreferredExtension: "ch.jroueche.RecordApp.TestScreen", handler: {broadcastAVC,error in
guard error == nil else {
print("Cannot load Broadcast Activity View Controller.")
return
}
if let broadcastAVC = broadcastAVC {
broadcastAVC.delegate = self
self.present(broadcastAVC, animated: true, completion: {
// broadcastactivityviewcontroller will perform the callback when the broadcast starts (or fails)
print("I've START")
})
}
})
Unlikeenter code here the RPSystemBroadcastPickerView solution, I'm getting the following error :
The preferred broadcast service could not be found.
My issue is similar to the following post :
App not showing up as a broadcast service in RPBroadcastActivityViewController
I also added the extension and the preferred extension identifier is correct.
Why would it be possible using the RPSystemBroadcastPickerView and not programmatically using RPBroadcastActivityViewControllerclass. That does not make sense for me.
Does someone have an idea of what could be the issue and how could I fix it ? Or a workaround in order to do this screen record.
Thanks in advance
It appears that RPBroadcastActivityViewController shows ONLY Broadcast Setup UI Extension, while RPSystemBroadcastPickerView shows ONLY Broadcast Upload Extension. But I have no idea why, as both of them are stated to show list of available providers/services.
It would be very helpful if someone could bring more details on the topic.

On iOS 15 a long press on the PS Button of the DualSense controller is opening the App Library and I don't receive a callback via the valueChangedHandler function. The App library which will be opened looks like this
This is how I handle all controller inputs:
func handleController(controller: GCController) {
controller.extendedGamepad?.valueChangedHandler = { [weak self] (gamepad: GCExtendedGamepad, element: GCControllerElement) in
guard let self = self else {
return
}
// no feedback received when performing a long press on the PS button
}
Can the game library be suppressed somehow? Sony's PS Remote Play app somehow manages to suppress it, but I don't know how, nor can I find anything in Apple's official API documentation.
Edit: Seems this problem only occurs on iPads, on iPhones this problem doesn't exist. Is there some API or anything on iPads to suppress this behaviour? I assume the most majority of users don't want to open the App Library in the middle of the game.
If someone ever faces the same problem you can actually disable system gestures for the Home button.
In Swift all you have to add is this line (controller is a GCController object)
controller.physicalInputProfile.buttons[GCInputButtonHome]?.preferredSystemGestureState = .disabled
In ObjectiveC it would work like this
controller.physicalInputProfile.buttons[GCInputButtonHome].preferredSystemGestureState = GCSystemGestureStateDisabled;
Thanks to the Apple employee who helped me here

Edit: on tvOS this isn't working as the PS button (menu button) of a controller always have to act as home event

I'm trying to use Replaykit to start a broadcast session (recording the App screen works ok) and it opens up a picker from where broadcasting Apps can be picked, Youtube, Facebook and Periscope show up but not my App, code:
if #available(iOS 10.0, *) {
RPBroadcastActivityViewController.load { broadcastAVC, error in
guard error == nil else {
print("Cannot load Broadcast Activity View Controller.")
return
}
if let broadcastAVC = broadcastAVC {
broadcastAVC.delegate = self
self.viewController.present(broadcastAVC, animated: true, completion: {
// broadcastactivityviewcontroller will perform the callback when the broadcast starts (or fails)
})
}
}
}
Full source code here, the code is in the startBroadcast function.
I also tried loading using withPreferredExtension and it says preferred broadcast service not found. When I go to the control centre to try starting a broadcast session I see no Start Broadcast button and no Apps, just Start Recording, I'm using IOS11 so I tried with a phone using IOS12 and same result concerning control centre.
How can I get my App to show in the picker, thanks?
Had to add the Broadcast Extension, in Xcode, File -> New -> Target -> Broadcast Upload Extension. This extension was then displayed in the picker.
Another common issue is that the Deployment Target for your app (specifically your app, not just your Broadcast Extension) needs to be at least iOS 14.0. If it's any lower, it won't show up even if your device is on the correct version.
I created a new app in Xcode and added the following code in the AppDelegate file
func updateCarWindow()
{
guard let screen = UIScreen.screens.first(where: { $0.traitCollection.userInterfaceIdiom == .carPlay })
else
{
// CarPlay is not connected
self.carWindow = nil;
return
}
// CarPlay is connected
let carWindow = UIWindow(frame: screen.bounds)
carWindow.screen = screen
carWindow.makeKeyAndVisible()
carWindow.rootViewController = CarViewController(nibName: nil, bundle: nil)
self.carWindow = carWindow
}
and called the function in function application. The app is not showing in the CarPlay external display.
You don’t have direct access to the carplay screen, carplay manages everything using the CPInterfaceController class that is able to display so called templates (such as CPListTemplate and a handful of others). Your ability to draw on the screen is pretty much limited to drawing maps in a CPMapContentWindow.
I recommend you read the Apple docs first starting here:
https://developer.apple.com/carplay/documentation/CarPlay-Navigation-App-Programming-Guide.pdf
Don’t forget to set the correct app permissions and carplay entitlements othereise it simply won’t work and it might not tell you why.
And a final word that the Carplay framework is only supposed to work with navigation apps. Everything else would require a lot of workarounds, not to mention it would never pass app review.
Hope this helps
Im using TwiterKit 3.0 framwork. And im using Deeplink to share a tweet for my application. But the problem is its presenting a new viewController and shows the twitter dialogue box. But my requirement is need to share like in Photos app sharing screen.
if let deepLinkurl = branchObject.getShortUrl(with: shareLinkProperties) {
let composer = TWTRComposer()
composer.setURL(URL(string: deepLinkURL))
composer.show(from: self) { result in
if (result == TWTRComposerResult.cancelled) {
print("Tweet composition cancelled")
}
}
If i run above code I get like this
But I need something like this.
You can use Branch's showShareSheet() method for sharing Branch links to other apps.
Here is how the link is shared when using the shareSheet and selecting Twitter from the list of the Apps.

I have the exact same issue as "Paul" posted here: Can not export audiofiles via "open in:" from Voice Memos App - no answers have yet been posted on this topic.
Essentially what I'm trying to do is simple:
After having recorded a Voice Memo on iOS, I select "Open With" and from the popup that is shown I want to be able to select my app.
I've tried everything I can think of and experimented with LSItemContentTypes without success.
Unfortunately I don't have enough reputation to comment on the existing post above, and I'm getting quite desperate for a solution to this. Any help is hugely appreciated, even just to know whether it's doable or not.
Thanks!
After some experimentation and much guidance from this blog post ( http://www.theappguruz.com/blog/share-extension-in-ios-8 ), it appears that it is possible to do this using a combination of app extensions (specifically an Action Extension) and app groups. I'll describe the first part which will enable you to get your recording from Voice Memos to your app extension. The second part -- getting the recording from the app extension to the containing app (your "main" app) -- can be done using app groups; please consult the blog post above for how to do this.
Create a new target within your project for the app extension, by selecting File > New > Target... from Xcode's menu. In the dialog box that prompts you to "Choose a template for your new target:" choose the "Action Extension" and click "Next".
CAUTION: Do not choose the "Share Extension" as is done in the blog post example above. That approach is more appropriate for sharing with another user or posting to a website.
Fill in the "Product Name:" for your Action Extension, e.g., MyActionExtension. Also, for "Action Type:" I selected "Presents User Interface" because this is the way Dropbox appears to do it. Selecting this option adds a view controller (ActionViewController) and storyboard (Maininterface.storyboard) to your app extension. The view controller is a good place to provide feedback to the user and to give the user an opportunity to rename the audio file before exporting it to your app.
Click "Finish." You will be prompted to "Activate “MyActionExtension” scheme?". Click "Activate" and this new scheme will be made active. Building it will build both the action extension and the containing app.
Click the disclosure triangle for the "MyActionExtension" folder in the Project Navigator (Cmd-0) to reveal the newly-created storyboard, ActionViewController source file(s), and Info.plist. You will need to customize these files for your needs. But for now ...
Build and run the scheme you just created. You will be prompted to "Choose an app to run:". Select "Voice Memos" from the list and click "Run". (You will probably need a physical device for this; I don't think the simulator has Voice Memos on it.) This will build and deploy your action extension (and its containing app) to your device. and then proceed to launch "Voice Memos" on your device. If you now make a recording with "Voice Memos" and then attempt to share it, you should see your action extension (with a blank icon) in the bottom row. If you don't see it there, tap on the "More" button in that row and set the switch for your action extension to "On". Tapping on your action extension will just bring up an empty view with a "Done" button. The template code looks for an image file, and finding none does nothing. We'll fix this in the next step.
Edit ActionViewController.swift to make the following changes:
6a. Add import statements for AVFoundation and AVKit near the top of the file:
// the next two imports are only necessary because (for our sample code)
// we have chosen to present and play the audio in our app extension.
// if all we are going to be doing is handing the audio file off to the
// containing app (the usual scenario), we won't need these two frameworks
// in our app extension.
import AVFoundation
import AVKit
6b. Replace the entirety of override func viewDidLoad() {...} with the following:
override func viewDidLoad() {
super.viewDidLoad()
// Get the item[s] we're handling from the extension context.
// For example, look for an image and place it into an image view.
// Replace this with something appropriate for the type[s] your extension supports.
print("self.extensionContext!.inputItems = (self.extensionContext!.inputItems)")
var audioFound :Bool = false
for inputItem: AnyObject in self.extensionContext!.inputItems {
let extensionItem = inputItem as! NSExtensionItem
for attachment: AnyObject in extensionItem.attachments! {
print("attachment = \(attachment)")
let itemProvider = attachment as! NSItemProvider
if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeMPEG4Audio as String)
//|| itemProvider.hasItemConformingToTypeIdentifier(kUTTypeMP3 as String)
// the audio format(s) we expect to receive and that we can handle
{
itemProvider.loadItemForTypeIdentifier(kUTTypeMPEG4Audio as String,
options: nil, completionHandler: { (audioURL, error) in
NSOperationQueue.mainQueue().addOperationWithBlock {
if let audioURL = audioURL as? NSURL {
// in our sample code we just present and play the audio in our app extension
let theAVPlayer :AVPlayer = AVPlayer(URL: audioURL)
let theAVPlayerViewController :AVPlayerViewController = AVPlayerViewController()
theAVPlayerViewController.player = theAVPlayer
self.presentViewController(theAVPlayerViewController, animated: true) {
theAVPlayerViewController.player!.play()
}
}
}
})
audioFound = true
break
}
}
if (audioFound) {
break // we only handle one audio recording at a time, so stop looking for more
}
}
}
6c. Build and run as in the previous step. This time, tapping on your action extension will bring up the same view controller as before but now overlaid with the AVPlayerViewController instance containing and playing your audio recording. Also, the two print() statements I've inserted in the code should give output that looks something like the following:
self.extensionContext!.inputItems = [<NSExtensionItem: 0x127d54790> - userInfo: {
NSExtensionItemAttachmentsKey = (
"<NSItemProvider: 0x127d533c0> {types = (\n \"public.file-url\",\n \"com.apple.m4a-audio\"\n)}"
);
}]
attachment = <NSItemProvider: 0x127d533c0> {types = (
"public.file-url",
"com.apple.m4a-audio"
)}
Make the following changes to the action extension's Info.plist file:
7a. The Bundle display name defaults to whatever name you gave your action extension (MyActionExtension in this example). You might wish to change this to Save to MyApp. (By way of comparison, Dropbox uses Save to Dropbox.)
7b. Insert a line for the key CFBundleIconFile and set it to Type String (2nd column), and set its value to MyActionIcon or some such. You will then need to provide the corresponding 5 icon files. In our example, these would be: MyActionIcon.png, MyActionIcon#2x.png, MyActionIcon#3x.png, MyActionIcon~ipad.png, and MyActionIcon#2x~ipad.png. (These icons should be 60x60 points for iphone and 76x76 points for ipad. Only the alpha channel is used to determine which pixels are gray, the RGB channels are ignored.) Add these icon files to your app extension's bundle, NOT the containing app's bundle.
7c. At some point you will need to set the value for the key NSExtension > NSExtensionAttributes > NSExtensionActivationRule to something other than TRUEPREDICATE. If you want your action extension to only be activated for audio files, and not for video files, pdf files, etc., this is where you would specify such a predicate.
The above takes care of getting the audio recording from Voice Memos to your app extension. Below is an outline of how to get the audio recording from the app extension to the containing app. (I'll flesh it out later, time permitting.) This blog post ( http://www.theappguruz.com/blog/ios8-app-groups ) might also be useful.
Set up your app to use App Groups. Open the Project Navigator (Cmd-0) and click on the first line to show your project and targets. Select the target for your app, click on the "Capabilities" tab, look for the App Groups capability, and set its switch to "On". Once the various entitlements have been added, click on the "+" sign to add your App Group, giving it a name like group.com.mycompany.myapp.sharedcontainer. (It must begin with group. and should probably use some form of reverse-DNS naming.)
Repeat the above for your app extension's target, giving it the same name as above (group.com.mycompany.myapp.sharedcontainer).
Now you can write the url of the audio recording to the app group's shared container from the app extension side. In ActionViewController.swift, replace the code fragment that instantiates and presents the AVPlayerViewController with the following:
let sharedContainerDefaults = NSUserDefaults.init(suiteName:
"group.com.mycompany.myapp.sharedcontainer") // must match the name chosen above
sharedContainerDefaults?.setURL(audioURL, forKey: "SharedAudioURLKey")
sharedContainerDefaults?.synchronize()
Similarly, you can read the url of the audio recording from the containing app's side using something like this:
let sharedContainerDefaults = NSUserDefaults.init(suiteName:
"group.com.mycompany.myapp.sharedcontainer") // must match the name chosen above
let audioURL :NSURL? = sharedContainerDefaults?.URLForKey("SharedAudioURLKey")
From here, you can copy the audio file into your app's sandbox, e.g., your app's Documents directory or your app's NSTemporaryDiretory(). Read this blog post ( http://www.atomicbird.com/blog/sharing-with-app-extensions ) for ideas on how to do this in a coordinated fashion using NSFileCoordinator.
