The iPhone SDK docs claim fopen() is a supported method of file access but I am unable to get it to return a FILE handle. I am accessing a directory which is included in my project. I have tried fopen ‘filename’,’dir/filename’,’./filename’,’./dir/filename’,’/dir/filename’ all returning with a null pointer. Some people report using it with no issue so I am sure it is something simple!
if you’re trying to access a file within your application bundle, you need to get the full path to it:
[[NSBundle mainBundle] pathForResource: FILENAME ofType: FILEEXTENSION]This returns an NSString, which you can pull a UTF8String out of and pass to fopen.
