Notes from iPhoneDevCampNYC InterfaceBuilder session

basics

- gui interface for UI elements
- benefits of using IB
- graphically add interface elements to your app
- draw connections between ui elems and controllers
- quickly move, add, delete elems
- isolate ui from app code
- creates a .nib file -> contains ::
- objects
- attributes
- relationships

- proxy objects -> "placeholder for an object that is used by the nib file but not stored in the nib file"
- first responder -> target for messages (if not set, message is sent to other objects in the chain)

windows and views

- one window per app
- multiple views

integration

- IB builds the View (in MVC terms)
- IB discovers outlets and actions of Controllers
- IB automatically detects changes in the XCode project classes and delegates connections

basic use

- to add a view, 

1. simply drag the object to your nib file
2. select view/object and open inspector window
3. select identity pane
4. type name of class in the Class field, or select the class from the combo box

- creating connections,

1. select source object and open connections inspector
2. click the circle object to the right of the outlet/action, drag over to target object
3. select action methods (if needed)

- remove a connection by clicking 'break connection' box to the left of the name of the connected object
