I am trying to play wvm files from the app documents folder since 3 days but without success...
I removed "file://" from my path but I still get 1013 error (as discussed here), does someone have some sample code or at least the procedure to follow to make it works properly?
WV_RegisterAsset(myFilePath) always return WViOsApiStatus(rawValue: 1013)
The file should exists because when I try this:
let fileManager = NSFileManager()
print(fileManager.fileExistsAtPath(myFilePath))
It returns true
Thanks in advance for your help!
Widevine Classic on iOS uses an "asset root" directory. When you initialize the library, you pass it in the settings dictionary using the key WVAssetRootKey.
After that, all local asset pathnames you pass to the library are relative to the AssetRoot.
One simple option is to use NSHomeDirectory() as the AssetRoot, and then trim it from the beginning of absolute pathnames.

I made the iOS app unity.
It also successfully selected data from sqlite.
But when I insert, the error below appears.
mono.data.sqlite.sqliteexception (0x80004005): attempt to write a read-only database
The path to the DB file is here.
string filepath = Application.dataPath + "/Raw/Data.db";
if (!File.Exists(filepath))
{
File.Copy(Application.streamingAssetsPath + "/Raw/Data.db", filepath);
}
I wonder if I should set write permissions or change the path of the file.
What should I do if I have to grant write permission?
If I have to change the route, where should I go?
In the official documentation you have this:
On many platforms, the streaming assets folder location is read-only; you can not modify or write new files there at runtime. Use Application.persistentDataPath for a folder location that is writable.
Solution: Use Application.persistentDataPath instead of streaming asset folder.
Hey I am using flutter_sound package for voice recording.
But when I made a File() object from recorder file path, I have got not expected error on iOS when I am trying call length() or readBytes() functions..
on Android everything working fine, so I tried compare the made files on both platforms, and they are little bit different
ANDROID File path = /storage/emulated/0/...
iOS File path = file:///Users/kleinpetr/Library/Developer/......
I think the problem is in the different paths.
The error on iOS looks like this
Cannot retrieve length of file, path =
'file:///Users/kleinpetr/Library/Developer/CoreSimulator/Devices/62B6742D-0FA4-4B92-B138
0D9E717DB91B/data/Containers/Data/Application/8587EB31-CF5D-4045-950B
6C011AE3EA96/Library/Caches/voice-message.m4a' (OS Error: No such file or directory, errno = 2)
So using File.fromUri(Uri.parse(fullPath)) worked for you. What you're providing to File class isn't path actually, but URI string (it has protocol specified file:// in the beginning). What you have to do is to parse URI and create a File from it.
I have an HTML file (webview.html, for now) with relative links to images and .js files. I need to load it, and those linked resources into an iOS app's WKWebView. All the files are stored in Resources/Non-Localized/.
I'm attempting to load the files using the following code during viewDidLoad():
print("loadWebView: Bundle.main = ", Bundle.main); // This prints
if let htmlUrl = Bundle.main.url(forResource: "webview", withExtension: "html") {
print("htmlUrl = ", htmlUrl) // Doesn't print
webView.load(URLRequest.init(url: htmlUrl))
}
The app loads without error, but also without the contents in the webview.
I get the first print statement, but not the second, indicating something is wrong with my URL or resource bundle configuration.
What am I doing wrong? Do I need to do anything in XCode to add these files to the project? Where should I be looking for error messages that will hint me in the correct direction in the future?
I needed to add the file to the Project. I did this by simply dragging the Finder file icon to the project tree in Xcode.
Alternatively (and my final solution), I dragged the parent directory's icon, making a folder reference, and then added subdirectory parameter to .url(forResource...).
I'm still working on getting informative errors out of the WebView.
I got little problem, I am downloading PDF and saving to location, I am using write method to save to location and everything seems to work on version iOS 10 and below, but I got problem with iOS11, I am getting false from method below, I checked path, and bytes and it is same on both devices.
(try? data.write(to: invoiceFileUrl, options: [.atomic])) != nil
try this
let data = NSData(contentsOf:url! as URL)
data?.write(to:invoiceFileUrl, atomically: true)
Have you tried simply moving the file around? I am guessing you are using URLSession to download said file ( or you should anyway ).
Then you can use FileManager to move the temporary file to your documents or whatever desired directory in your app's container.
FileManager.default.moveItem(at:temporaryURL, to: destinationURL)
In case you prefer using paths there is also:
FileManager.default.moveItem(atPath: temporaryPath, toPath: destinationPath)
Though I personally don't use paths often (anymore) because it can lead to a whole load of inconsistencies and other issues you just don't want to deal with. Whatever backend you have try to move to NSURL or URL as quickly as you can with any received data; it'll make your life easier and most importantly more consistent accross foundation API's.

I'm trying to get my iPhone app to load text from a file into a string array, with 1 line from the file per array element.
I've created an input file as a text file using sublime text. I dragged the file (which is located inside of a folder inside of my project directory) into xCode into a folder in the same location in the project heirarchy.
I also tried adding it as a bundle (by copying the folder and renaming it with the .bundle extension), to no avail. Currently, my app has the file in 2 places (Obviously I plan to delete the unneeded version, but I'm not sure how this will work so I've left it for now).
I've written a function that I want to read my file, and assemble its contents into an array:
func readFromFile(filename: String) -> [String]? {
guard let theFile = Bundle.main.path( forResource: fileName, ofType: "txt") else {
return nil // ALWAYS returns nil here: Seems 'filename' can't be found?????
}
do { // Extract the file contents, and return them as a split string array
let fileContents = try String(contentsOfFile: theFile)
return fileContents.components(separatedBy: "\n")
} catch _ as NSError {
return nil
}
}
As it stands, the function always returns nil at the location commented in the code.
I've been working on this for ~6hrs (and tried every suggestion I could find on StackOverflow, google etc) and I'm just getting more and more confused by the differences between the various versions of Swift and intricacies of iOS development. I can't seem to find a consistent answer anywhere. I've checked the apple documentation but it's too high level with no example code for me to understand at my swift beginner level.
I also tried naming the file with a ".txt" extension but that didn't help either.
The file must certainly be named alert01.txt if you are going to refer to it as forResource: "alert01", ofType: "txt".
Loading from a bundle will not work. The file needs to be part of your project as shown in the first entry.
However, your code is not going to work because you have created a folder reference. That means the folder PanicAlertFiles is being copied with all its contents into your bundle. Your code will need to dive into that folder in order to retrieve your file. Use path(forResource:ofType:inDirectory:) to do that, or (if you don't want to have to code the file name explicitly) get the folder and then use the FileManager to examine its contents.
