how to invalidate one nstimer i need

- (void)start{
    NSTimer *mtimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(scheduleSomeNSTimer:) userInfo:nil repeats:YES];
}

- (void)scheduleSomeNSTimer:(NSTimer *)timer{
    NSTimer *newtimer = [NSTimer scheduledTimerWithTimeInterval:60.0 target:self selector:@selector(showAction:) userInfo:nil repeats:NO];
}

- (void)showAction:(NSTimer *)timer{
    NSLog(@"action show!");
}

if i want invalidate one of the nstimer which schedule by function - (void)addSomeNSTimer:(NSTimer *)timer

the application will create newtimer repeatly ,so when i need to invalidate one of these newnstimer ,how can i find the object i need

for example:the application开发者_如何学运维 create 4 nstimers and run in loop how can i find one of them and invalidate

You should keep a reference to the timer in your class and do:

self.myTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(scheduleSomeNSTimer:) userInfo:nil repeats:YES];

so whenever you want to invalidate it, just do:

[self.myTimer invalidate];

You can achieve this by below:

As per your feedback, please have a look at below answer.

in .h file, declare on Array:

NSMutableArray *arrTimers;

in .m file, add timer in this array where ever you create the timer.

NSTimer *mtimer = [[NSTimer alloc] init];

mtimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(scheduleSomeNSTimer:) userInfo:nil repeats:YES];

[arrTimers addObject:mtimer];

Then you can invalidate it like below:

NSTimer *myTimer = (NSTimer *)[arrTimers objectAtIndex:1];
if(myTimer != nil)
    {
        [myTimer invalidate];
        myTimer = nil;
    }

I hope it will resolve your issue.

if(timer == mtimer)
{

   if(mtimer != nil)
   {
        [mtimer invalidate];
        mtimer = nil;
   }
}

if(timer == newtimer)
{
    if(newtimer != nil)
    {
        [newtimer invalidate];
        newtimer = nil;
    }
}

Cheers.

To_play is NSTimer object.

[To_play invalidate];

Declare a NSMutableArray and in Your scheduleSomeNSTimer method, add the newtimer object into the array. When you invalidate a timer object in this array, you also need to remove it from the array.

You can do it without keeping a reference to the timer. Use a flag instead.

@property(nonatomic, assign) BOOL invalidateTimer; 

Source code related to the Timer:

[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(scheduleSomeNSTimer:) userInfo:nil repeats:YES];

- (void)scheduleSomeNSTimer:(NSTimer *)timer
{
   if(YES == invalidateTimer)
   {
     if([timer isValid])
     {
       [timer invalidate];
       timer = nil;
     }
   }
}
