How to pass a variable through a selector?

I have a method

-(void)myMethod:(MyObject*)obj

And I am detaching a new thread

[开发者_开发知识库NSThread detachNewThreadSelector:@selector(myMethod) toTarget:self withObject:nil];

How can I pass a MyObject* through @selector(myMethod)?

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

You will definitely want that @selector(myMethod:) instead of @selector(myMethod). They mean different things.
