Batman vs Hulk?

Now I know Hulk would crush Iornman like a tin can, and nethier of Bats or Iornmans toys would work on Hulk, but Bats has something stark doesn't 1000x times of training and different skills in almost ever thing, I would image Batman would try to talk to the Hulk and calm the Hulk down, something i can't see Iornman doing and witch might give batman a chance but i don't know. who do you think would win?
