connecting addCenterButtonWithImage with viewController in iOS

Question

i am creating a button using the following code:

[self addCenterButtonWithImage:[UIImage imageNamed:@"scan.png"]
 highlightImage:[UIImage imageNamed:@"scan_hover.png"]];

i need to connect this to a method. how do i do that? i am very new to ios development, so sorry if this is a stupid question.

would it be possible to load a view controller on clicking the button?( i have the code to be executed in the viewdidload method) basically this button is there to customise the tab bar to have the centre tab item jutting out...

You can connect to a IBAction in interface builder

-(IBAction)someMethod:(id)sender{
}

You can connect programatically

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addTarget:self action:@selector(someMethod:) forControlEvents:UIControlEventTouchUpInside];
