ios - swift 在应用组容器中创建目录

Question

如何在我的应用程序组容器中创建目录？

我试过用作文件管理器:

let directory: NSURL = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("APP_GROUP_IDENTIFIER")!

但这不会创建目录...我如何才能在此文件夹中创建目录？

Answer 1

containerURLForSecurityApplicationGroupIdentifier 将 URL 返回到组容器。
要创建目录，请将新目录名称附加为路径组件

let fileManager = NSFileManager.defaultManager()
if let directory = fileManager.containerURLForSecurityApplicationGroupIdentifier("APP_GROUP_IDENTIFIER") {
    let newDirectory = directory.URLByAppendingPathComponent("MyDirectory")
    try? fileManager.createDirectoryAtURL(newDirectory, withIntermediateDirectories: false, attributes: nil)
}

swift 3:

let fileManager = FileManager.default
if let directory = fileManager.containerURL(forSecurityApplicationGroupIdentifier: "APP_GROUP_IDENTIFIER") {
    let newDirectory = directory.appendingPathComponent("MyDirectory")
    try? fileManager.createDirectory(at: newDirectory, withIntermediateDirectories: false, attributes: nil)
}
