Cordova-ionic ngCordova ios or iPhone 5 file read error code ENCODING_ERR

Question

I am using a cord-ion structure to create an application. I am new to iOS or iPhone in my requirement, I have to read the file in the application. I am reading a file in an Android application, but the same code shows an error (code: 5).

I follow the types of code:

in android:

$cordovaFile.writeFile(( 'user.json', data, {'append':false} )).then(function(result) { alert('file created.'); alert(JSON.stringify(result)); }, function(err) { // An error occured. Show a message to the user alert('file writed'); alert(JSON.stringify(err)); }); 

I can create files, write, read data and delete a file, but on an ios phone I cannot create a file using the same code.

on iPhone:

 var data = {"user":{"name":"errer","email":" [e-mail] ","username":"sdfsdfsd"}}; $cordovaFile.writeFile(( 'user.json', data, {'append':false} )).then(function(result) { // Success! alert('file created.'); alert(JSON.stringify(result)); }, function(err) { // An error occured. Show a message to the user alert('file writed'); alert(JSON.stringify(err)); }); 

I just change my directory: cordova.file.cacheDirecotry / cordova.file.applicationDirectory

 $cordovaFile.createFile(( cordova.file.cacheDirecotry+'user.json', true )).then(function(result) { // Success! alert('file created.'); alert(JSON.stringify(result)); }, function(err) { // An error occured. Show a message to the user alert('file writed'); alert(JSON.stringify(err)); }); 

the whole way of getting errors, like code: 12 or code: 5

please help me solve this problem or give me an idea to get the path to the application file.

Answer 1

Refer to the source documentation: - https://github.com/apache/cordova-plugin-file/blob/master/doc/index.md#ios-file-system-layout

iOS has some read-only directories. Try changing your path.

Let me know if this does not work for you.

Answer 2

I have some progression.

First, I warn my cordova.file.dataDirectory or cordova.file.documentsDirectory file. They are

 file:///var/mobile/...../Library/NoCloud 

and

 file:///var/mobile/..../Documents 

Then I create the file without a prefix and succeed. Referring to this https://github.com/driftyco/ng-cordova/issues/362

and a success message indicates that the file’s own URL is stored in

 file:///var/mobile/...../Library/files 

This is pretty weird. By the way, I'm adding

 <preference name="iosPersistentFileLocation" value="Library" /> 

according to https://github.com/apache/cordova-plugin-file/blob/master/doc/index.md#ios-persistent-storage-location

All tests are performed on iOS, I have not tested Android.

Update

All the following code worked for me and gave a successful answer

 $cordovaFile.checkFile('/test.data') $cordovaFile.createFile('test.data',false) $cordovaFile.checkDir('/') 

Hope this can solve your problems.

 /* Here is what I am using for my Android and IOS apps Keep attention to a couple of things: - Android and IOS have other directorynames for files - Android devices have different root (myFSRootDirectory1 = Samsung Tab 3, msFSRootDirectory2 = Samsung SII) - $cordovaFile functions prefixes all pathnames with root $cordovaFileTransfer functions needs absolute pathnames Here I create the prefixes for File functions and FileTransfer functions for Android and IOS */ // The $ionicPlatform and ionic.Platorm are from Ionic framework // $ionicPlatform.ready(function() { if (ionic.Platform.isAndroid()) { // If running on Android console.log('cordova.file.externalDataDirectory: ' + cordova.file.externalDataDirectory); // // I use cordova.file.externalDataDirectory because this url is for Android devices // If you remove the app from the device these url are cleared too on the device.

Perhaps this is due to a typo? You have cordova.file.cacheDirecotry . Should not be: cordova.file.cacheDirectory ?
