IOS下面如果文件夹中的文件名包含特殊字符Delphi无法取到

Submitted by hubdog on Sat, 2020-03-21 17:22

TDirectory.GetFiles方法用的是linux的函数,对特殊字符的文件会认为是目录导致无法取得列表

下面这个函数用NSFileManager绕过了这个问题

  1.  
  2.  
  3. function GetFiles(APath:string):TStringDynArray;
  4.  
  5. var
  6.  
  7.   fm:NSFileManager;
  8.  
  9.   files:NSArray;
  10.  
  11.   I: Integer;
  12.  
  13.   list:TStrings;
  14.  
  15.   f:string;
  16.  
  17.   isDir:boolean;
  18.  
  19. begin
  20.  
  21.   fm := TNSFileManager.Wrap(TNSFileManager.OCClass.defaultManager);
  22.  
  23.   files:=fm.contentsOfDirectoryAtPath(StrToNSStr(APath), nil);
  24.  
  25.  
  26.  
  27.   list:=TStringList.Create;
  28.  
  29.   try
  30.  
  31.     for I := 0 to files.count-1 do
  32.  
  33.     begin
  34.  
  35.       f:=TPath.Combine(APath, NSStrToStr(TNSString.Wrap(files.objectAtIndex(i))));
  36.  
  37.       isDir:=False;
  38.  
  39.       fm.fileExistsAtPath(StrToNSStr(f), @isDir);
  40.  
  41.       if isDir then
  42.  
  43.         Continue;
  44.  
  45.       list.Add(f);

  109.         Continue;
