Actions are methods that are part of your controller class and are declared with a special keyword, IBAction. This keyword tells Interface Builder that this is an action and can be triggered by a control. In short if you want to have interface objects in the nib (like buttons) trigger methods in the controller class then you would use special methods called Actions.
What are Outlets?
When building an iPhone app there comes a need for the code you write to interact with the elements you create in Interface Builder, this is called an Outlet.
The Outlet is and instance variable, and our controller class can refer to objects in the nib by using Outlets. Outlets are used to effect objects in your nib such as text labels, buttons and so on. By declaring an outlet and connecting that outlet to an object in the nib, you could use the outlet from within your code to change any object in your nib.
Jquery and WordPress, the 6 Million Dollar upgrade
The combination of WordPress and Jquery fits together just like Steve Austin and the 6 Million Dollar Man. Imagine your website as the meaty parts of Steve Austin that didn’t get turned into hamburger after his horrendous crash, and Jquery as the bionic upgrades stitched to his body by the OSI. Your blog may look great and get the ladies like Lee Majors but, what really makes the chicks drool are the bionic enhancements.
