一、UISegmentControl是一个分段控件，父类是UIControl，内涵数个button，并且都有对应下标index；
NSArray *titles = @[@"护卫队",@"三军仪仗队",@"步兵方队",@"炮兵方队"];
UISegmentedControl *SegmentedC = [[UISegmentedControl alloc]initWithItems:titles];
SegmentedC.frame = CGRectMake(20, 40, 335, 40);
SegmentedC.backgroundColor = [UIColor whiteColor];
// 设置文字颜色
SegmentedC.tintColor = [UIColor redColor];
// [SegmentedC setTintColor:[UIColor whiteColor]];
// 默认选中项
SegmentedC.selectedSegmentIndex =0;
// 修改某项的title
[SegmentedC setTitle:@"女兵方阵" forSegmentAtIndex:2];
// 指定某项宽度
[SegmentedC setWidth:100 forSegmentAtIndex:1];
// 设置title 文字大小 颜色
NSDictionary *dic = @{NSFontAttributeName:[UIFont systemFontOfSize:15],NSForegroundColorAttributeName:[UIColor blueColor]};
NSDictionary *dic1 = @{NSFontAttributeName:[UIFont systemFontOfSize:15],NSForegroundColorAttributeName:[UIColor yellowColor]};
[SegmentedC setTitleTextAttributes:dic forState:UIControlStateNormal];
[SegmentedC setTitleTextAttributes:dic1 forState:UIControlStateSelected];
// 添加点击事件
[SegmentedC addTarget:self action:@selector(handleSegmented:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:SegmentedC];
[SegmentedC release];
