Stop Method Execution after 5 Minute - objective-c

Question

How can i stop the execution of the method after a certain time?
I am calling method as below:
[NSTimer scheduledTimerWithTimeInterval:5.0f
target:self
selector:#selector(doSomeTask) userInfo:nil repeats:YES];
Here i have given interval of 5 Seconds. So this method will get called after every 5 seconds, So once the reaches to specified time i want to stop this method execution.

Answer 1

Take a counter variable, and increase in every call by 5 (as time interval is 5 sec ) like
counter = counter+5;
-(void) doSomeTask {
if (counter<=60) { // 5 min = 300 300/5 = 60
// Write method body here
counter = counter+5
}
else {
[timer invalidate];
}
}

Answer 2

If you want to stop execution of the method after 5 min. Then you can add code like this
#interface YourClass () {
int count;
}
#end
-(void)viewDidLoad {
count = 5;
NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:#selector(doSomeTask) userInfo:nil repeats:YES];
}
-(void) doSomeTask
{
count = count + 5;
if (count==300)
{
[timer invalidate];
timer=nil;
}
}

Answer 3

#define TIMER_LIFE_IN_SECONDS 300.0
#interface YourClass () {
NSTimeInterval _startTime;
}
self.timer = [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:#selector(doSomeTask) userInfo:nil repeats:YES];
_startTime = [NSDate timeIntervalSinceReferenceDate];
- (void) doSomeTask
{
// do thing
NSTimeInterval now = [NSDate timeIntervalSinceReferenceDate];
if (now - _startTime > TIMER_LIFE_IN_SECONDS) {
[self.timer invalidate];
self.timer = nil;
}
}

Answer 4

you can try like this
NSTimer *reachTimer;
NSInteger secondsLeft;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
secondsLeft = 0;
reachTimer = [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:#selector(updateCounter:) userInfo:nil repeats:YES];
}
-(void)updateCounter:(NSTimer *)theTimer{
secondsLeft = secondsLeft+5;
if(secondsLeft>=300) // 60sec * 5min= 300
{
[reachTimer invalidate];
}
}

Answer 5

Try this;
int count;
NSTimer *timer;
-(void)startTimertillLimit:(int)limit {
count = 0;
timer = [NSTimer scheduledTimerWithTimeInterval:5
target:self
selector:#selector(doSomething:)
userInfo:[NSString stringWithFormat:#"%d",limit]
repeats:YES];
}
-(void)doSomething:(NSTimer*)sender
{
int limit = (int)[sender.userInfo intValue];
count = count + 5;
if (count > limit)
{
[timer invalidate];
timer=nil;
count = 0;
}
}

Answer 6

Try to create NSTimer that will be called after some time only once :
NSTimer *previous [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:#selector(doSomeTask) userInfo:nil repeats:YES];
[NSTimer scheduledTimerWithTimeInterval:300 target:self selector:#selector(stopPrevious) userInfo:nil repeats:NO];
-(void)stopPrevious{
[previous invalidate];
}
