iOS: How to use NSThread

ios_nsthread.m

Create Thread

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

Create a selector method called by our thread

- (void)myMethod { 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    // code here
    [pool release]; 
}

Note: If you want to do something to the main thread inside your new thread, use performSelectorOnMainThread.

[self performSelectorOnMainThread:@selector(myMethod) withObject:nil waitUntilDone:false];
