Question

I have to loop in particluar method which do some task. I have used the method performselectoronmainthread wait until done method. Its working fine if i call it for once. But It fails when I call it in for loop. ie
this is the code:

for (int i=1;i<=3;i++) {
            ip=i;
        [self performSelectorOnMainThread:@selector(createThread:) withObject:ip waitUntilDone:YES];
    }

-(void)createThread:(NSString*)ipIs
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSLog(@"Ip address  is :%@",ipIs);
    [SimplePingHelper ping:ipIs target:self sel:@selector(Result:)];
    [pool release];

}
- (void)Result:(NSNumber*)success {
    //do some stuff

}

The problem is that this code works fine when I run this loop once and It calls Result method. But it execution path changes when I try to use loop in performSelectorOnMainThread to pass different variables into it.Then It doesnt call result method.

I am looping because I want to run these same methods on different variables but task to be performed would be same.I am also using waituntil done:YES value..but still it is not working
Any idea ?

try creating other thread

myThread = [[NSThread alloc] initWithTarget:self selector:@selector(setupTimerThread) object:nil];
[myThread start];
-(void)setupTimerThread
{


NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];



timer2 = [NSTimer timerWithTimeInterval:0.04
                                         target:self
                                       selector:@selector(triggerTimer:)
                                       userInfo:nil
                                        repeats:YES];
NSRunLoop* runLoop = [NSRunLoop currentRunLoop];

[runLoop addTimer:timer2 forMode:NSDefaultRunLoopMode];
[runLoop run];

[pool release];
}
-(void)triggerTimer:
{
//this method will be called in loop set loop interval by setting the timers time duration in above method
}

EDIT :

int ip=0;
-(void)triggerTimer:
  {
 ip++; // till ip<=3
 [self createThread:ip];
  }
