在app group container swift中创建目录

Question

如何在App的小组容器中创建目录？

我已尝试用作文件管理器：

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

但是没有创建目录...如何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)
}

斯威夫特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)
}

1. 选中启用＆＃34;应用组＆＃34; 权利。它可以从项目 - ＆gt;启用能力 - ＆gt;应用程序组 - ＆gt;开启。

2. 添加应用程序组标识＆＃34; group.com.companyName.exampleApp＆＃34; ，如上图所示。

3. 现在，您可以使用指定的标识符访问应用程序组容器。

   let appIdentifier = "group.com.companyName.exampleApp"
   let fileManager = NSFileManager.defaultManager()
   let container = fileManager.containerURLForSecurityApplicationGroupIdentifier(appIdentifier)
   

4. 如果您正确设置了所有内容，您将在＆＃34;容器＆＃34;中获得一个URL地址。

5. 现在，

   do{
      if let container = container {
   
       let directoryPath  = container.URLByAppendingPathComponent("sampleDirectory")
   
       var isDir : ObjCBool = false
       if let path = directoryPath?.path where fileManager.fileExistsAtPath(path, isDirectory:&isDir) {
         if isDir {
           // file exists and is a directory
         } else {
           // file exists and is not a directory
         }
       } else if let directoryPath = directoryPath {
         // file or directory does not exist
         try fileManager.createDirectoryAtURL(directoryPath, withIntermediateDirectories: false, attributes: nil)
       }
     }
   } catch let error as NSError {
     print(error.description)
   }
