NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 

NSString* foofile = [documentsPath stringByAppendingPathComponent:@"filename" ];

NSFileManager Référence de la classe

contentsOfDirectoryAtPath:error: Performs a shallow search of the specified directory and returns the paths of any contained items.

  • (NSArray *)contentsOfDirectoryAtPath:(NSString )path error:(NSError *)error Parameters path The path to the directory whose contents you want to enumerate. error On input, a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information. Return Value An array of NSString objects, each of which identifies a file, directory, or symbolic link contained in path. Returns an empty array if the directory exists but has no contents. If an error occurs, this method returns nil and assigns an appropriate error object to the error parameter

Discussion This method performs a shallow search of the directory and therefore does not traverse symbolic links or return the contents of any subdirectories. This method also does not return URLs for the current directory (“.”), parent directory (“..”), or resource forks (files that begin with “._”) but it does return other hidden files (files that begin with a period character). If you need to perform a deep enumeration, use the enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: method instead.

The order of the files in the returned array is undefined.

Availability Available in iOS 2.0 and later.
