Answer 1

You could use stringByDeletingLastPathComponent twice:

NSString *pathStr = @"/a/b/c/d";
NSString *path = [[pathStr stringByDeletingLastPathComponent] stringByDeletingLastPathComponent];
NSLog(@"%@", path);

Returns /a/b.

How about:

NSString *path = @"/a/b/c/d";
NSArray *components = [path pathComponents]

NSLog(@"%@", [components objectAtIndex: 1]); // <- output a
NSLog(@"%@", [components objectAtIndex: 2]); // <- output b
NSLog(@"%@", [components lastObject]); // <- output d
