Why agk::GetFirstFile() and agk::GetNextFile() work under Windows, but under iOS do not work?

inline std::vector<std::string>	GetFileList( const char* szPath, const char* szExt = "*" )
{
        agk::SetFolder	( szPath );

std::vector<string> filelist;
	char*	filefind = agk::GetFirstFile();
	char*	fileExt = "";
	
	if ( strcmp ( filefind, "" ) != 0 )
	{
		fileExt = agk::GetStringToken( filefind,	".", 2 );
		if ( strcmp ( szExt, "*" ) == 0 || strcmp ( szExt, fileExt ) == 0 )
		{
			filelist.push_back( filefind );
		}
		
		while ( strcmp ( filefind, "" ) != 0 )
		{
			filefind = agk::GetNextFile();

if ( strcmp ( filefind, "" ) != 0 )
			{
				fileExt = agk::GetStringToken( filefind,	".", 2 );
				if ( strcmp(szExt,"*") == 0 || strcmp (szExt, fileExt) == 0 )
				{
					filelist.push_back( filefind );
				}
			}
		}
	}
	else
	{
		agk::Error 	( "GetFirstFile() - empty!" );
	}

if ( filelist.empty() )
	{
		char szText[256] = "";
		sprintf 	( szText, "Directory: '%s' is empty!", szPath );
		agk::Error 	( szText );
	}

std::sort		( filelist.begin(), filelist.end() );	
	agk::SetFolder	( "" );
	return filelist;
}

+ Code Snippet

inline std::vector<std::string>	GetFileList( const char* szPath, const char* szExt = "*" )
{
        agk::SetFolder	( szPath );

	std::vector<string> filelist;
	char*	filefind = agk::GetFirstFile();
	char*	fileExt = "";
	
	if ( strcmp ( filefind, "" ) != 0 )
	{
		fileExt = agk::GetStringToken( filefind,	".", 2 );
		if ( strcmp ( szExt, "*" ) == 0 || strcmp ( szExt, fileExt ) == 0 )
		{
			filelist.push_back( filefind );
		}
		
		while ( strcmp ( filefind, "" ) != 0 )
		{
			filefind = agk::GetNextFile();

			if ( strcmp ( filefind, "" ) != 0 )
			{
				fileExt = agk::GetStringToken( filefind,	".", 2 );
				if ( strcmp(szExt,"*") == 0 || strcmp (szExt, fileExt) == 0 )
				{
					filelist.push_back( filefind );
				}
			}
		}
	}
	else
	{
		agk::Error 	( "GetFirstFile() - empty!" );
	}

	if ( filelist.empty() )
	{
		char szText[256] = "";
		sprintf 	( szText, "Directory: '%s' is empty!", szPath );
		agk::Error 	( szText );
	}

	std::sort		( filelist.begin(), filelist.end() );	
	agk::SetFolder	( "" );
	return filelist;
}

What folder name are you passing in? And does it start with a '/' or not?

Okay, is that exact path and its files added in your Resources folder in your Xcode project? And I mean exactly with the same case.

If you don't start with a '/', I think the SetFolder command will attempt to set the folder relative to its current location. I could be wrong. I always use it to make sure that the path starts at the top of the app (either actual executable directory or the sandbox area).

1) Directory "Data" in Resources folder.
2) "/Data/Textures/Sprites/Start/3_yeti/" - did not help.

And all the subdirectories under Resources/Data appear with the same letter cases that you are using in your code?

What versions of Xcode and iOS are you working with?

I'll have to try a test from Xcode on Monday to see if I have the same issue.

This appears to be a very legitimate and serious bug!

If you pass in "" as the path, it will read the files in the executable directory. Anything else fails.

I tried with and without leading '/'. I tried using agk::SetCurrentDir instead of agk::SetFolder.

I will report it in the google list and set it as confirmed.

Commander, it turns out not to be a bug but a usage issue with Xcode.

Paul provided the solution. See his response in the google issue I posted.

It's such a simple and easy fix.
