10.3.2 Find response method of “Send” button using Cycript
Since we’ve already known that the superview of “Send” button is a CKMessageEntryView
object in section 10.2, we can repeat what we’ve done in section 10.2.2 and get the superview
without further tests:

invisibility. Well, let’s test the 1st UIButton, “UIButton: 0x1605a8b0” with Cycript:
