Question

我正在使用Phonegap开发iOS应用。此应用程序应该能够从Internet下载文件，将它们存储到先前在设备中创建的目录中。我已经为Android目标做了同样的事情，我的代码工作正常。它在手机中创建目录，下载并保存文件。在iOS中，我的代码不起作用。我试图在网络上搜索解决方案而没有结果。

以下是代码：

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

function onDeviceReady() {
    alert("device ready");
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
}

function onFileSystemSuccess(fileSystem) {
    console.log(fileSystem.name);
    console.log(fileSystem.root.name);              
    var directoryEntry = fileSystem.root;
    directoryEntry.getDirectory("myDir", {create: true, exclusive: false}, onDirectorySuccess, onDirectoryFail);
}

function onDirectorySuccess(parent) {
    console.log(parent);
    window.localStorage.setItem("directory_path",parent.toURL()+'/');
}

function onDirectoryFail(error) {
    alert("Unable to create new directory: " + error.code);
}

function fail(evt) {
    console.log(evt.target.error.code);
}

在控制台中，我可以看到此输出：
