Answer 1

You have to write it as
(IBAction)buttonPressed {
Infact it should be
-(IBAction)buttonPressed {
May be - is missing that might be creating this error.
Hope this helps.
EDIT:
If still it doesnt help, then you may try this.
-(IBAction)buttonPressed:(id)sender {
EDIT-2:
Also you are missing a ; at the end of statement no 4
that is
NSString *zip=[self.zips objectAtIndex:zipRow]
You should add a semicolon(;) there at the end
Hope this solves it

Answer 2

There's a - missing right at the beginning before (IBACTION).

Answer 3

I have tested this code and its working properly.
change the "(NSInteger)component" as per requirement of picker.
- (IBAction) buttonPressed:(id)sender {
NSInteger stateRow =[pickerView selectedRowInComponent:"(NSInteger)component"];
NSInteger zipRow = [pickerView selectedRowInComponent:"(NSInteger)component"];
NSLog(#"stateRow - %d",stateRow);
NSLog(#"zipRow - %d",zipRow);
}
And also put - (IBAction) buttonPressed:(id)sender; in .h file
