I have a method
-(void)myMethod:(MyObject*)obj
And I am detaching a new thread
[NSThread detachNewThreadSelector:@selector(myMethod) toTarget:self withObject:nil];
How can I pass a MyObject* through @selector(myMethod)?

A:
[NSThread detachNewThreadSelector:@selector(myMethod:) toTarget:self withObject:myObjectInstance];
You will definitely want that @selector(myMethod:) instead of @selector(myMethod). They mean different things.

Should have seen the withObject parameter. Thanks for the tip.

More explicitly, the selector is the *name* of the message you're sending. The `:` is part of the method's name and thus part of the selector. You can have a method named `myMethod` and one named `myMethod:` live right alongside each other with no confusion — they're no more similar to the compiler than `kill` and `skill`. In fact, in Smalltalk (which Obj-C was based on), this is how getters and setters were normally written.
