Does anyone have any great disciplinary tactics for stopping your child from hitting you?

I have a 2 year old who hits me (kicks too) when he is frustrated and can’t get what he wants. He’s a lovely sweet boy with a lot of love to give but gets very angry at times and hits me. I wondered if anyone has had this problem and how they have overcome it other than just letting them “grow out of it” I’ve started taking his toys away when we’re at home but this can’t obviously be enforced when we’re out and about…. any suggestions…and I really don’t believe in smacking him ffiw. He’s done this since he was about 10 months old and seems to go through phases of it…but i want to REALLY sort it out. :(
