adding second to timer iOS game sprite kit - ios

Question

I am trying to add a few seconds to countdown timer each time when enemy and player node contacts.
Also when the player reach to some certain point I want player to pass to another level. I am sending part of the code . Could anybody help me to solve this problem. By the way because I am new to programming my code is a little hard to read . Sorry for that.
Thanks
-(void)update:(CFTimeInterval)currentTime{

if(countDownInt > 0 ){ //if counting down to 0 show counter
countDown.text = [NSString stringWithFormat:#"%i", countDownInt];
}
else if (countDownInt == 0){
countDown.text =#"0";
Level2 *level2 = [Level2 sceneWithSize:self.frame.size];

Create a boolean flag that the update method checks to see if it should add seconds.
Add the following variable and set self.addSeconds = NO; initially:
#property (nonatomic) BOOL addSeconds;
Set self.addSeconds =YES; in the method where your player hits your enemy:
Add the following to the very beginning of the Update:
if(self.addSeconds == YES)
{
CountDownInt+= 5 //Change this to add as many seconds as you want
self.addSeconds=NO;
}
This should do the trick.
