how to create an "array of selectors' in objective-c

i'm using the iphone sdk (3.0) and i'm trying to create an array of selectors to invoke a variety of methods within one class.

Element or class LIKE selector for JQuery?

For whatever reason I have these classes called .main_sub1 , .main_sub2 etc. Never mind why I can't have .main .sub .

Android: Selector isn"t working as expected in TableRow selection

I have a TAbleLayout in my XML with 1 row i.e. te headings row. Other all rows, I add dynamically. I want to make a row selected on clicking it & on touching it. I added clickListener to each row and am able to trap click event. But when the mouse is pressed or kept pressed, I see color change, then again it comes to normal color. I want the color to stay changed until I click other row or click somewhere else to deactivate the selected row.
