iPhone SDK: Add UIBarButtonItem action programmaticly

Question

Hello,

I have several UIBarButtonItems, and I want to set the action when you press it programmaticly. How can I do this? Please give in-depth instructions since i just started to work with the SDK.

EDIT: if it would be possible non-programmaticly, please also reply :)

The action is going to Google.com, and the button is the search button in this project: (download): click here

Answer 1

First create an outlet to the items in IB. Then you can modify the methods called by using [myItem setTarget:] and [myItem setAction:].

See target action

ETA: Is there any particular reason you want to do it programmatically?

ETAA: To do it non-programmatically, make a function with return type IBAction, and argument (id)sender, like so:

- (IBAction)myMethod:(id)sender;

With whatever implementation you like. Then, in IB, drag an object object from the Library to the MainWindow.xib window, and in the identity window (cmd-6), give it the class that has your function. Then, in the connections window of that object (cmd-5), you can drag from your function name to whichever interface object you want.

I strongly suggest you read mac dev on IB. The connections and bindings section will discuss this particular issue. Also, a tutorial like so: yet another tutorial will probably help.
