[IOS_UI Control] iOS code implements common Controls UIButton, UISlider, Uiswitch, Uisegmentedcontrol

The most commonly used controls in iOS UIButton, UISlider, Uiswitch, Uisegmentedcontrol by the Xib file drag generation is very simple, in fact, the implementation of code is the same simple, of course, the implementation of code can grasp more things.

The 4 types of controls mentioned in, UIButton buttons, uislider sliders, Uiswitch switches, Uisegmentedcontrol categories

First create an empty application project named Codecontrols

The AppDelegate.h and APPDELEGATE.M files are the same as The iOS code implementation in Hello World
