I need to run a sort of CRUD in directories and files through an IOS application.

This application uses the IONIC framework, which in turn uses Cordova and AngularJS features.

The questions are:

Regarding permissions, does the IOS system allow this kind of functionality?
If yes, through what exactly is it possible to create these files and directories? (AngularJS, Javascript "pure", Cordova, or even libs like Jquery, etc.).
How can I create, read, modify, and delete these files and directories?

It is possible by using the window.requestFileSystem method, which is native to Cordova. Do not forget to add the read / write permission for files in your configuration file. For iOs, edit your config.xml file by adding these lines:

<feature name="File">
    <param name="ios-package" value="CDVFile" />
</feature>
<feature name="FileTransfer">
    <param name="ios-package" value="CDVFileTransfer" />
</feature>

And below is an example of how to use the requestFileSystem, to open the foor folder and create the bar.txt file

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}

function gotFS(fileSystem) {
   fileSystem.root.getDirectory("foo", {create: true}, gotDir);
}

function gotDir(dirEntry) {
    dirEntry.getFile("bar.txt", {create: true, exclusive: true}, gotFile);
}

function gotFile(fileEntry) {
    // manipule o arquivo aqui da forma que você quiser
}
