Question

I am trying to stop the timer. My problem is when I try to stop the timer the value of timer is nil and it is not getting invalidated. if there any way to stop the timer except this ?

My code is like

timer is defined in header file – and also synthesized.

if([str_Message isEqualToString:ON] // if the command to start timer

{


 if(!timer) 

{

tmr_CallWebService = [[NSTimer scheduledTimerWithTimeInterval:Time_TracingInterval target:ClassTracing selector:@selector(startLocationTracing) userInfo:nil repeats:YES]retain];

}

//to stop timer

else if([str_Message isEqualToString:OFF])
{
if(timer)

{

[timer invalidate];
timer = nil;

}

Please help me out… thanks in advance

[str_Message isEqualToString:ON] should be like this [str_Message isEqualToString:@"ON"]. similarly for the comparison with OFF. Use @"OFF".
