ios - Cocos2d: How to create a global timer? -


i'm doing cocos2d project i'm newbie in. please bear me.

when creating timer in game use throughout app. 

-(void)onenter {     [super onenter];     [self.timercountdown invalidate];           self.timercountdown = [nstimer scheduledtimerwithtimeinterval:1 target:self selector:@selector(timercountdown:) userinfo:nil repeats:yes];  }  -(void) timercountdown: (nstimer*) timer {      self.secondsleft--;  }

apparently when click game go view, onenter got called again triggers timer count again.

so question how should approach problem make timer continues same counts i'm in different views 2 mins.

if purely ios app, thought 2 options. first 1 pass through segue , second 1 use userdefaults.

however don't think same cocos2d. there no segue well!

any advice grateful. thanks.

don't use nstimer. instead use delta times passed update: method.

@interface yourclass () {     cgfloat _timeout; } @end  @implementation yourclass  -(void)onenter {     [super onenter];     _timeout = 30.0; }  - (void)update:(cctime)deltatime {     _timeout -= deltatime;     if (_timeout < 0.0) {         // thing         _timeout = 30.0;     } }

that repeating timeout; you'll need variable single-shot timeout.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
