Set delay animation for UIPicker?

Question

If I have this code below to tell the UIPicker if nothing is selected to set the feet to 1, How can I delay this action a few seconds?

// If feet values are zero.
if (([feetPicker selectedRowInComponent:0] == 0 & [feetPicker selectedRowInComponent:1] == 0)){
// Set to one foot.
[feetPicker selectRow:1
          inComponent:1
             animated:YES];


}

[NSTimer    scheduledTimerWithTimeInterval:2.0    target:self    selector:@selector(fireMethod)    userInfo:nil repeats:NO];

The above code can be placed whenever you want to start the timer.

-(void)fireMethod {
    // If feet values are zero.
if (([feetPicker selectedRowInComponent:0] == 0 & [feetPicker selectedRowInComponent:1] == 0)){
// Set to one foot.
[feetPicker selectRow:1
          inComponent:1
             animated:YES];


    }
