Question

I am working on an application where i have to call a thread repeatedly. In that thread we have to parse an XML and i have to get updated data from that xml. now please guide me how to call that thread repeatedly? if my thread is in working and my code calls it again, then i think it will have a crash on it.

Answer 1

Separate the code into a new method

-(void) thisMethodWillRunAsASeparateThread
{
    //Threads need their own pool.
    NSAutoreleasePool *pool = [NSAutoreleasePool new];
    while (thisThreadShouldRun)
    {
        // run xml parsing code
    }
    [pool release];
}

and to start the thread:

[NSThread detachNewThreadSelector:@selector(thisMethodWillRunAsASeparateThread) toTarget:self withObject:nil];
