如何在FinderSync中找到我的文件扩展名

Question

我正在执行folderSync，我想使用attr显示文件的图标， 但这不起作用。

  

NSDictionary * at = [[[NSFileManager defaultManager] attributeOfItemAtPath：@“ / Users / macbookpro / Downloads / ccc /个人文档/999/iOS_12_Beta_Profile.mobileconfig”错误：无]；

folderSync中的结果：

NSFileCreationDate = "2018-07-02 06:11:56 +0000";
NSFileExtensionHidden = 0;
NSFileGroupOwnerAccountID = 20;
NSFileGroupOwnerAccountName = staff;
NSFileHFSCreatorCode = 0;
NSFileHFSTypeCode = 0;
NSFileModificationDate = "2018-07-02 06:12:04 +0000";
NSFileOwnerAccountID = 501;
NSFileOwnerAccountName = macbookpro;
NSFilePosixPermissions = 384;
NSFileReferenceCount = 1;
NSFileSize = 9030;
NSFileSystemFileNumber = 8616904835;
NSFileSystemNumber = 16777220;
NSFileType = NSFileTypeRegular;

但是我可以在Vc中看到它：

NSFileCreationDate = "2018-07-02 06:11:56 +0000";
NSFileExtendedAttributes =     {
    category = <31>;
    documentVersionId = <32393738 31>;
    id = <32393136 34>;
    state = <32>;
};
NSFileExtensionHidden = 0;
NSFileGroupOwnerAccountID = 20;
NSFileGroupOwnerAccountName = staff;
NSFileHFSCreatorCode = 0;
NSFileHFSTypeCode = 0;
NSFileModificationDate = "2018-07-02 06:12:04 +0000";
NSFileOwnerAccountID = 501;
NSFileOwnerAccountName = macbookpro;
NSFilePosixPermissions = 384;
NSFileReferenceCount = 1;
NSFileSize = 9030;
NSFileSystemFileNumber = 8616904835;
NSFileSystemNumber = 16777220; 
NSFileType = NSFileTypeRegular;
