how can i set image to UIswitch on the white round part

Do not try to modify the UISwitch. Instead create your custom control that you will be able to fully customize. Subclass the UIControl and implement your own user interface. As a reference this repo may help you.

The user has made an opinion, but I don't know how to achieve it.
The user hopes to send a "DaDa" sound like a typewriter in the NSTextView, when the keyboard is entered with the keyboard, and the default setting is not found. How do I finish this idea?
Make a subclass of NSTextView. In your subclass, override keyDown:. In your keyDown: override, play a sound using an instance of NSSound.

What I'd like to get is the same transparent border, up pointing arrow and tint for my own pop-up views.
Any help would be appreciated.
Thanks,

You have to use the UIPopOverController.
Setting the contentViewController to your TableViewController. To attach it to a button you can use the presentPopoverFromRect:inView:permittedArrowDirections:animated: method.
