i have problem nstimer. received "sigabrt" error , [nscftimer intvalue]: unrecognized selector sent instance

these code:

-(void)detectionmove:(nsnumber*)arrayindex{       static bool notfind = false;     static int countvariable = 0;     static int countrilevamenti = 0;      notfind = false;      for(int = countvariable+1; i<[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]count]; i++){          if(!notfind){              if((actualaccelerometerx+sensibilitymovement) >= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuex] && (actualaccelerometerx-sensibilitymovement) <= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuex] &&                (actualaccelerometery+sensibilitymovement) >= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuey] && (actualaccelerometery-sensibilitymovement) <= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuey] &&                (actualaccelerometerz+sensibilitymovement) >= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuez] && (actualaccelerometerz-sensibilitymovement) <= [[[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]objectatindex:i]valuez])             {                 countvariable = i;                 notfind = true;                 countrilevamenti++;             }         }     }      if(!notfind)         return;      else if(countvariable+1 == [[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]]  arraypositionmove]count]){          if(countrilevamenti + tollerance >= [[[[sharedcontroller arraymovement]objectatindex:[arrayindex intvalue]] arraypositionmove]count])             movementdetected = [arrayindex intvalue];         else             nslog(@"troppo veloce");          countvariable = 0;         notfind = false;         countrilevamenti = 0;                 return;     }      [nstimer scheduledtimerwithtimeinterval:timetocatch target:self selector:@selector(detectionmove:) userinfo:(nsnumber*)arrayindex repeats:no];       }

you have wrong signature method

- (void)timerfiremethod:(nstimer*)thetimer

not nsnumber

--edit2--

nsmutabledictionary *mydictionary = [[nsmutabledictionary alloc] init];   [mydictionary setobject:arrayindex forkey:@"index"]; [nstimer scheduledtimerwithtimeinterval:timetocatch target:self selector:@selector(detectionmove:) userinfo:mydictionary repeats:no];

--edit--

if want keep old method can call somewhere else nsnumber argument have create new method nstimer call , in implementation of nstimer method call nsnumber method whatever number appropriate.

-(void)detectionmove:(nsnumber*)arrayindex{  // still whatever }  -(void)automaticdetectionmove:(nstimer*)thetimer{  [self detectionmove:whatevernumber]; }  // update new method name [nstimer scheduledtimerwithtimeinterval:timetocatch target:self selector:@selector(automaticdetectionmove:) userinfo:(nsnumber*)arrayindex repeats:no];
