I need to access every file in a folder, including file that exist within nested folders. An example folder might look like this.

 -k.txt
 -d.jpg
 c

This code worked for me.

NSMutableString *allHash;  

  -(NSString*)getIterate:(NSString*)path {

        allHash = [NSMutableString stringWithString:@""];

        NSDirectoryEnumerator *de= [[NSFileManager defaultManager] enumeratorAtPath:path];
        NSString *file;
        BOOL isDirectory;

        for(file in de)
        {

            //first check if it's a file
            NSString* fullPath = [NSString stringWithFormat:@"%@/%@",path,file];

            BOOL fileExistsAtPath = [[NSFileManager defaultManager] fileExistsAtPath:fullPath isDirectory:&isDirectory];
            NSLog(@"Check=>%d",fileExistsAtPath);

            if (!isDirectory) //its a file
            {
                //Do with filepath
            }
            else{ //it's a folder, so recurse
                [self enumerateFolder:fullPath];
            }
        }

        return allHash;


    }

    -(void) enumerateFolder:(NSString*)fileName
    {

        NSDirectoryEnumerator *de= [[NSFileManager defaultManager] enumeratorAtPath:fileName];
        NSString* file;
        BOOL isDirectory;

        for(file in de)
        {
            //first check if it's a file
            BOOL fileExistsAtPath = [[NSFileManager defaultManager] fileExistsAtPath:file isDirectory:&isDirectory];

            if (fileExistsAtPath) {
                if (!isDirectory) //its a file
                { 
                  //Do with file  
                }
                else{ //it's a folder, so recurse

                    [self enumerateFolder:file];
                }
            }
            else printf("\nenumeratefolder No file at path %s",[file UTF8String]);
        }
    }
