button setTitleColor: forState:

  UIButton *backButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 25, 50, 30)];

    [backButton setTitle:@"返回" forState:UIControlStateNormal];

    backButton.backgroundColor = [UIColor whiteColor];

    [backButton setTitleColor:mRGBToColor(0x282828) forState:UIControlStateNormal];
