问题
I just update xcode to v4.4 and when I run my project, xcode crash and the simulator's screen stay black. One of the solution I find is that I had to update to mountain lion (I had Lion) and to re-install xcode.
But I wanna know if there's another option without updating to mountain lion.
*Re-install xcode doesn't work.
