Cracked Cheesecake

I have been making cheesecakes ever since I was around ten years old. I have to they turn out to be pretty good but I always have the same issue. They crack. I dont know why or how they're always so pretty when I take them out of the oven but give them twenty minutes and boom there's this huge crack in the middle of my once perfect cheesecake. Ive heard rumors of different things you can try like surrounding the cake in water while it cooks or turning the temperature down and maybe one day I'll try one of these things but for now I guess I will just have to accept that my cheesecakes just aren't perfect.
