- runloop:
The run loop to associate with the display link.
- mode:

Discussion
You can associate a display link with multiple input modes. While the run loop is executing in a mode you specify, the display link notifies the target when the system requires new frames.
You can specify a custom mode or use one of the modes listed in RunLoop.
The run loop retains the display link. To remove the display link from all run loops, call invalidate().
