My goal is executing some statements if timer still ticks.
while (mainTimer == //is Ticking){
//execute things
}
how can i control my NSTimer mainTimer, is or not ticking ?
You can ask your “
mainTimer” object if it’s valid via the NSTimer “isValid” method. You can also see when it’ll fire next by checking the “fireDate” method.If you’re doing this on a separate “
NSThread” (e.g. in the background), there’s a handy “isExecuting” method, too.(all the blue links up there point to the Apple documentation)
