Custom views are now a bit confusing, with a rough idea of how to write:

1. Create a new view controller that designates this view controller as the root View Controller for window

2. Customize the view Ltview, explicitly ltview the internal controls, declare the properties, override the initWithFrame: Layout method, and first add the child view. Improve the display effect, you need to define an initialization method, the parameter is the display property of the view

3. Custom views, explicit internal controls, declared as properties, overriding initWithFrame: layout methods, adding child views

4. Inside the view controller, override the Loadview method to specify a blank view of the view controller as a custom view (or you can not establish a custom view in the View controller's Viewdidload method, load the view, refine the view controller)

5. Set the proxy for the input box inside the view controller and add an event for the button.

And don't forget the memory management

Then is the newly learned to some touch method, iOS will touch into three time periods:

1. Touch Start

-(void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (Uievent *) event;

2. Touch Mobile

-(void) touchesmoved: (Nsset<uitouch *> *) touches withevent: (Uievent *) event;

3. Touch End

-(void) touchesended: (Nsset<uitouch *> *) touches withevent: (Uievent *) event;
