I am creating an iMessage Sticker Pack Extension that have stickers that contain texts. I don't see any option in Xcode to localize the stickers? Is it possible to localize stickers?
Maybe it's obvious, but you can manage it inside of an extension. If you create not a pack, but extension, you can fetch exact stickers for your localization
If you want to show different sticker-assets dependant on e.g. your device's language, you need to create a iMessage Application instead of a Sticker Pack Application.
And you need to write some code as it's not possible to have this behaviour within a simple Sticker Pack Application.
However this is pretty simple. For a start, follow this tutorial:
http://blog.qbits.eu/ios-10-stickers-application/
Some code-syntax there is outdated, but XCode will help you to easily fix that.
You can place your localized resources inside different folders and drag'n'drop them into you XCode project (make sure to check "Create folder references"):

You can then do something like this in your viewDidLoad():
//-- get current language set
var imageSetPath = "/EN"; //-- default to english
let languageCode = NSLocale.preferredLanguages[0]
if languageCode.hasPrefix("zh-Hans") { imageSetPath = "/CNS" }
else if languageCode.hasPrefix("zh-Hans") { imageSetPath = "/CNT" }
else if languageCode.hasPrefix("ko") { imageSetPath = "/KR" }
else if languageCode.hasPrefix("ja") { imageSetPath = "/JP" }
//-- load localized stickers
imageUrls = recursivePathsForResources(path: Bundle.main.bundlePath + imageSetPath, type: "png")
loadStickers(urls: imageUrls)
where
func recursivePathsForResources(path: String, type: String) -> [URL] {
// Enumerators are recursive
let enumerator = FileManager.default.enumerator(atPath: path)
var filePaths = [URL]()
while let filePath = enumerator?.nextObject() as? String {
if NSURL(fileURLWithPath: filePath).pathExtension == type {
let url = URL(fileURLWithPath: path).appendingPathComponent(filePath)
filePaths.append(url)
}
}
return filePaths
}

How do I grab all of the checked languages for Localization programmatically in Swift with Xcode 12?
I want to have these languages in an array that I can display as a picker view so the user can seamlessly change the language without having to change the language of their device. I want to avoid hard coding this.

This might do the trick:
func localizations() -> [String] {
guard let contentsURLs = try? FileManager.default.contentsOfDirectory(at: Bundle.main.bundleURL, includingPropertiesForKeys: nil) else { return [] }
let identifiers = contentsURLs.compactMap { anURL -> String? in
guard anURL.pathExtension == "lproj" else { return nil }
return anURL.deletingPathExtension().lastPathComponent
}
let humanReadableNames = identifiers.compactMap { anIdentifier in
return Locale.current.localizedString(forIdentifier: anIdentifier)?.localizedCapitalized
}
return humanReadableNames
}
I even transformed them into human readable languages names, instead of having for instance "zh-Hans" for "Chinese (Simplified)".
Of course, if you handle yourself your locale, your might want to use a different Locale.current, but you get the idea...
I create an iOS app and added a framework to it. The generated framework doesn't have an assets folder like the generate Single View App. So I made an Assets folder inside the framework folder and drag and drop it to xcode, choose the target as my framework.
I tried using the asset but the asset doesn't show up. Can show one show me how to correctly do this? is it possible to create an assets folder inside a framework?
I am very new to iOS so any guidance would be much appreciated. Thanks in advance.
Add Asset catalog to framework target as usual via New File... > Resources, but to get resource from such asset it needs to specify bundle explicitly, as in below example...
Assuming that ImageProvider is in framework target, the code could be
public class ImageProvider {
// convenient for specific image
public static func picture() -> UIImage {
return UIImage(named: "picture", in: Bundle(for: self), with: nil) ?? UIImage()
}
// for any image located in bundle where this class has built
public static func image(named: String) -> UIImage? {
return UIImage(named: named, in: Bundle(for: self), with: nil)
}
}
of course you can name such class anyhow.
Here's how I do it.
First of all, here's how you can create a Bundle to hold your assets like images.
First, create a new target:
Navigate to main Xcode menu, File => New => Target. Choose the "macOS tab" then
from "Framework & Library" select "Bundle".
Give it your desired name and hit Finish. You should see the bundle in your project folder.
Second, Configuration changes in build settings of Bundle:
Go to Build Settings on your bundle target and change the Base SDK to be iOS.
Third, Add images:
Add your images to the Bundle directly, no need to add an assets folder. Just drag and drop.
Fourth, build the bundle:
Choose your bundle as a destination and choose the generic iOS device and hit Command + B
Fifth, the .bundle will appear in your products folder under your project folder. Right-click on it and view it in Finder and then drag and drop it inside of your main project folder.
Finally, here's how I'd access the assets inside of your bundle.
// Empty UIImage array to store the images in it.
var images = [UIImage]()
let fileManager = FileManager.default
let bundleURL = Bundle.main.bundleURL
let assetURL = bundleURL.appendingPathComponent("MyBundle.bundle") // Bundle URL
do {
let contents = try fileManager.contentsOfDirectory(at: assetURL,
includingPropertiesForKeys: [URLResourceKey.nameKey, URLResourceKey.isDirectoryKey],
options: .skipsHiddenFiles)
for item in contents { // item is the URL of everything in MyBundle imgs or otherwise.
let image = UIImage(contentsOfFile: item.path) // Initializing an image
images.append(image!) // Adding the image to the icons array
}
}
catch let error as NSError {
print(error)
}
You will have the .plist file inside of your bundle, therefore, I suggest you handle this by a simple condition to check if the file name is Info.plist don't create an image out of it.
Here's how I handled it in a very trivial way.
let fileManager = FileManager.default
let bundleURL = Bundle.main.bundleURL
let assetURL = bundleURL.appendingPathComponent("Glyphs.bundle")
do {
let contents = try fileManager.contentsOfDirectory(at: assetURL, includingPropertiesForKeys: [URLResourceKey.nameKey, URLResourceKey.isDirectoryKey], options: .skipsHiddenFiles)
for item in contents {
let imageName = item.lastPathComponent
if imageName != "Info.plist" {
let image = UIImage(contentsOfFile: item.path)
icons.append(image!)
}
}
}
catch {
//print(error)
showAlert(withTitle: "Error", message: "Can't get the icons.")
}
I had the same problem.
scenario:
our framework will be consumed iOS/OSX
a lot of PNGs inside Framework
we want pngs in iOSApp && MacOs
let's assume out framework project and target is "MyCustomFramework.framework" (usual yellow icon..) already in our app
-
func filePathInFrameworkBundle(name: String)->String{
let myBundlePath = Bundle.main.bundlePath
#if os(iOS)
let inMyFW = myBundlePath +
"/Frameworks" +
"/MyCustomFramework.framework"
#elseif os(OSX)
let inMyFW = myBundlePath +
"/Contents/Frameworks" +
"/MyCustomFramework.framework" + "/Versions/A/Resources"
#else
#endif
let pathInBundle = inMyFW+"/"+name
return pathInBundle
}
Now You can use THIS path in usual image loading calls.
For SwiftUI use:
Add an Asset catalog to your framework project (eg, "Media.xcassets").
Add a resource, like a Color Set. Let's say you name your color "Thunder".
Create a file in your framework called "Color+Extensions.swift" (or whatever you like).
Inside this file do:
import SwiftUI
private class LocalColor {
// only to provide a Bundle reference
}
public extension Color {
static var thunder: Color {
Color("Thunder", bundle: Bundle(for: LocalColor.self))
}
}
I imagine this works for other asset types as well.
In the project which is using your framework, once you have added the import for your framework, you should be able to just use the color normally:
Rectangle().foregroundColor(.thunder)
I am trying load SCNParticleSystem from download bundle which i am not able to load.
Path for the resource.
file:///var/mobile/Containers/Data/Application/A91E9970-CDE1-43D8-B822-4B61EFC6149B/Documents/so/solarsystem.bundle/Contents/Resources/
let objScene = SCNParticleSystem(named: "stars", inDirectory: directory)
This object is nil.
This is a legitimate problem since SceneKit does not provide an out-of-the-box solution for initializing particle systems from files that are outside of the main bundle (the only init method SCNParticleSystem.init(named:inDirectory:) implies that SCNParticleSystem.scnp files are in the main bundle).
Luckily for us .scnp files are just encoded/archived SCNParticleSystem instances that we can easily decode/unarchive using NSKeyedUnarchiver:
extension SCNParticleSystem {
static func make(fromFileAt url: URL) -> SCNParticleSystem? {
guard let data = try? Data(contentsOf: url),
let object = try? NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data),
let system = object as? SCNParticleSystem else { return nil }
return system
}
}
If you do not need to support iOS 9 and iOS 10 you can use NSKeyedUnarchiver.unarchivedObject(ofClass: SCNParticleSystem.self, from: data) instead of NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(_:) and type casting, which was introduced in iOS 11.0.
Another issue that you're most likely to encounter is missing particle images. That is because by default SceneKit will look for them in the main bundle. As of current versions of iOS (which is iOS 12) and Xcode (Xcode 10) particle images in .scnp files (particleImage property) are String values which are texture filenames in the main bundle (that might change, but probably won't, however there's not much else we could use).
So my suggestion is to take that filename and look for the texture file with the same name in the same directory where the .scnp file is:
extension SCNParticleSystem {
static func make(fromFileAt url: URL) -> SCNParticleSystem? {
guard let data = try? Data(contentsOf: url),
let object = try? NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data),
let system = object as? SCNParticleSystem else { return nil }
if let particleImageName = system.particleImage as? String {
let particleImageURL = url
.deletingLastPathComponent()
.appendingPathComponent(particleImageName)
if FileManager.default.fileExists(atPath: particleImageURL.path) {
system.particleImage = particleImageURL
}
}
return system
}
}
You can just set the URL of the image file and SceneKit will handle it from there.
As a little side-note, the recommended directory for downloadable content is Application Support directory, not Documents.
Application Support: Use this directory to store all app data files except those associated with the user’s documents. For example, you might use this directory to store app-created data files, configuration files, templates, or other fixed or modifiable resources that are managed by the app. An app might use this directory to store a modifiable copy of resources contained initially in the app’s bundle. A game might use this directory to store new levels purchased by the user and downloaded from a server.
(from File System Basics)
Don't have enough reps to add the comment so adding it as the answer.
The answer by Lësha Turkowski works for sure but was had issues with loading the particle images using only NSURL.
All particles were appearing square which meant,
If the value is nil (the default), SceneKit renders each particle as a
small white square (colorized by the particleColor property).
SCNParticleSystem particleImage
In the documentation it says You may specify an image using an
NSImage (in macOS) or UIImage (in iOS) instance, or an NSString or
NSURL instance containing the path or URL to an image file.
Instead of using the NSURL, ended up using the UIImage and it loaded up fine.
extension SCNParticleSystem {
static func make(fromFileAt url: URL) -> SCNParticleSystem? {
guard let data = try? Data(contentsOf: url),
let object = try? NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data),
let system = object as? SCNParticleSystem else { return nil }
if let particleImageName = system.particleImage as? String {
let particleImageURL = url
.deletingLastPathComponent()
.appendingPathComponent(particleImageName)
if FileManager.default.fileExists(atPath: particleImageURL.path) {
// load up the NSURL contents in UIImage
let particleUIImage = UIImage(contentsOfFile: particleImageURL.path)
system.particleImage = particleUIImage
}
}
return system
}
}
I found out, that sometimes when dragging a SCNParticleSystem file into your project (probably form a different project) a silent error can happen due to some bugs in Xcode. As a result you can't get a reference to an instance of your SCNParticleSystem.
Solution: Check your BuildSettings in your target. The SCNPaticleSystem AND the associated ImageFile should be listed there and then you should get it right. (see screenShot below)
Ultimately I'm trying to launch the Main app from the Widget by doing
UIApplication.SharedApplication.OpenUrl(new NSUrl("MyURLScheme//"));
So I have an iOS application with a today extension. I would like to access my main application's URL Scheme. Is that possible? My URL Scheme is inside my Plist file of my main application and not my today extension. Can I just reference the one from the main app? I tried getting it from CFBundleURLTypes and CFBundleURLSchemes but they both turn up as "null".
Probably because it's looking in the widget's Plist and not the main app's Plist.
var asdf2 = NSBundle.MainBundle.InfoDictionary["CFBundleURLTypes"];
var asdf3 = NSBundle.MainBundle.InfoDictionary["CFBundleURLSchemes"];
Here is a screenshot of where the URL Scheme is located in the main app's Plist file. I'd prefer to not have to store duplicate information in the today extension's Plist file. And I'd also prefer to not have to hardcode the URL Scheme into the today extension's code.
would be something (ugly) like this :
var arr = (NSBundle.MainBundle.InfoDictionary["CFBundleURLTypes"] as NSMutableArray);
var urlTypes = arr.GetItem<NSDictionary>(0);
var schemes = urlTypes.ObjectForKey(new NSString("CFBundleURLSchemes")) as NSMutableArray;
var scheme = schemes.GetItem<NSString>(0).ToString();
You might need to create an App Group for your app and your extension which will allow you to place a plist or any other file for that matter that you want to share between the 2 into a shared location on disk.
Here's an article that explains how this is done:
https://learn.microsoft.com/en-us/xamarin/ios/app-fundamentals/file-system#configure-an-app-group
You can refer below URL
stackoverflow
extension Bundle {
static let externalURLSchemes: [String] = {
guard let urlTypes = main.infoDictionary?["CFBundleURLTypes"] as? [[String: Any]] else {
return []
}
var result: [String] = []
for urlTypeDictionary in urlTypes {
guard let urlSchemes = urlTypeDictionary["CFBundleURLSchemes"] as? [String] else { continue }
guard let externalURLScheme = urlSchemes.first else { continue }
result.append(externalURLScheme)
}
return result
}()
}
I am developing a share extension for photos for my iOS app. Inside the extension, I am able to successfully retrieve the UIImage object from the NSItemProvider.
However, I would like to be able to share the image with my container app, without having to store the entire image data inside my shared user defaults. Is there a way to get the PHAsset of the image that the user has chosen in the share extension (if they have picked from their device)?
The documentation on the photos framework (https://developer.apple.com/library/ios/documentation/Photos/Reference/Photos_Framework/) has a line that says "This architecture makes it easy, safe, and efficient to work with the same assets from multiple threads or multiple apps and app extensions."
That line makes me think there is a way to share the same PHAsset between extension and container app, but I have yet to figure out any way to do that? Is there a way to do that?
This only works if the NSItemProvider gives you a URL with the format:
file:///var/mobile/Media/DCIM/100APPLE/IMG_0007.PNG
which is not always true for all your assets, but if it returns a URL as:
file:///var/mobile/Media/PhotoData/OutgoingTemp/2AB79E02-C977-4B4A-AFEE-60BC1641A67F.JPG
then PHAsset will never find your asset. Further more, the latter is a copy of your file, so if you happen to have a very large image/video, iOS will duplicate it in that OutgoingTemp directory. Nowhere in the documentation says when it's going to be deleted, hopefully soon enough.
I think this is a big gap Apple has left between Sharing Extensions and PHPhotoLibrary framework. Apple should've be creating an API to close it, and soon.
You can get PHAsset if image is shared from Photos app. The item provider will give you a URL that contains the image's filename, you use this to match PHAsset.
/// Assets that handle through handleImageItem:completionHandler:
private var handledAssets = [PHAsset]()
/// Key is the matched asset's original file name without suffix. E.g. IMG_193
private lazy var imageAssetDictionary: [String : PHAsset] = {
let options = PHFetchOptions()
options.includeHiddenAssets = true
let fetchResult = PHAsset.fetchAssetsWithOptions(options)
var assetDictionary = [String : PHAsset]()
for i in 0 ..< fetchResult.count {
let asset = fetchResult[i] as! PHAsset
let fileName = asset.valueForKey("filename") as! String
let fileNameWithoutSuffix = fileName.componentsSeparatedByString(".").first!
assetDictionary[fileNameWithoutSuffix] = asset
}
return assetDictionary
}()
...
provider.loadItemForTypeIdentifier(imageIdentifier, options: nil) { imageItem, _ in
if let image = imageItem as? UIImage {
// handle UIImage
} else if let data = imageItem as? NSData {
// handle NSData
} else if let url = imageItem as? NSURL {
// Prefix check: image is shared from Photos app
if let imageFilePath = imageURL.path where imageFilePath.hasPrefix("/var/mobile/Media/") {
for component in imageFilePath.componentsSeparatedByString("/") where component.containsString("IMG_") {
// photo: /var/mobile/Media/DCIM/101APPLE/IMG_1320.PNG
// edited photo: /var/mobile/Media/PhotoData/Mutations/DCIM/101APPLE/IMG_1309/Adjustments/FullSizeRender.jpg
// cut file's suffix if have, get file name like IMG_1309.
let fileName = component.componentsSeparatedByString(".").first!
if let asset = imageAssetDictionary[fileName] {
handledAssets.append(asset)
imageCreationDate = asset.creationDate
}
break
}
}
}
