UISwitch(开关控件)、UISegmentedControl(分段控件)
一、UISwitch
1、初始化
UISwitch *s1 = [[UISwitch alloc]initWithFrame:CGRectMake(50, 170, 100, 200)];
2、设置相关属性
s1.onTintColor = [UIColor blueColor];
s1.tintColor = [UIColor greenColor];
s1.thumbTintColor = [UIColor redColor];
3、设置开关状态
s1.on = YES;
4、添加事件
    [s1 addTarget:self action:@selector(myswitch) forControlEvents:UIControlEventValueChanged];
   
    [s1 addTarget:self action:@selector(myswitch:) forControlEvents:UIControlEventValueChanged];
5、加入父视图
 [self.view addSubview:s1];
添加事件的方法
  -(void)myswitch{
    NSLog(@"触发了改方法");
}
-(void)myswitch:(UISwitch *)s{
    UISwitch *s2 = (UISwitch *)[self.view viewWithTag:1];
    NSLog(@"%d",s.isOn);
    NSLog(@"%d",s2.isOn);
}
二、UISegmentedControl
1、初始化
(1)方式1
UISegmentedControl *seg  =[[UISegmentedControl alloc] initWithFrame:CGRectMake(30, 100, 200, 40)];//创建时初始化大小,但是不设置每段的参数
(2)方式2
UISegmentedControl *seg1 = [[UISegmentedControl alloc] initWithItems:@[@"1",@"2",@"3"]];//初始化时直接给出初始的段数及title
2、设置相关属性
(1)[seg setTitle:@"我的" forSegmentAtIndex:0];//设置某一段的标题文字
(2)[seg setImage:[UIImage imageNamed:@"lanzuan"] forSegmentAtIndex:0];//设置某一分段的image,注意title和image二者只能存在一个
(3)[seg insertSegmentWithTitle:@"2" atIndex:0 animated:NO];//在下标为0的位置插入一个标题为2的分段,注意下标的合理性
(4)[seg insertSegmentWithImage:[UIImage imageNamed:@"1.png"] atIndex:0 animated:NO];//在下标为0的位置插入一个分段,设置其图片
(5)seg.tintColor = [UIColor whiteColor];//设置segment的边框颜色及文字/图片颜色
(6)[seg removeSegmentAtIndex:0 animated:YES];//移除某一分段
(7)[seg removeAllSegments];//移除所有的分段
(8)seg.numberOfSegments; //移除某一分段
(9)seg.selectedSegmentIndex = 0;//默认选中第几个选段
(10)NSString *str = [seg titleForSegmentAtIndex:0];//获取某一段的title
(11)UIImage  *image = [seg imageForSegmentAtIndex:0];//获取某一段的图片
(12)[seg setWidth:30 forSegmentAtIndex:0];//设置某一段的宽度
(13)[seg setBackgroundImage:[UIImage imageNamed:@"imsend"] forState: UIControlStateNormal barMetrics: UIBarMetricsDefault];//设置常态下的背景图
(14)[seg setBackgroundImage:[UIImage imageNamed:@"logoin_6"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];//设置选中的背景图
(15)[seg addTarget:self action:@selector(change:) forControlEvents:UIControlEventValueChanged];//绑定监听事件
UISegmentedControl *segment1 = [[UISegmentedControlalloc]initWithItems:@[@"你好",@"欢迎",@"加入"]];//初始化时直接给出初始的段数及title
    segment1.frame = CGRectMake(90, 240, 200, 50);//初始化大小
  
    [segment1 insertSegmentWithImage:[UIImage imageNamed:@"3.jpg"] atIndex:1 animated:YES];//插入图片并允许动画
   
     NSLog(@"段数:%zi",segment1.numberOfSegments);//获取段数
    [segment1 setTitle:@"我们" forSegmentAtIndex:0];
    NSString *str = [segment1 titleForSegmentAtIndex:1];//获取图片标题,注意图片中插入的位置要对应起来
   
    NSLog(@"图片标题=%@",str);
    UIImage *image = [segment1 imageForSegmentAtIndex:1];
    NSLog(@"图片=%@",image);
   
    //[segment1 setWidth:100 forSegmentAtIndex:0];//设置某段的宽
    //[segment1 setEnabled:NO forSegmentAtIndex:0];//设置某一段是否被激活
    //[segment1 setEnabled:NO];//整体不被激活
   
    segment1.selectedSegmentIndex = 1;//设置默认选中项
    NSLog(@"%zi",segment1.selectedSegmentIndex);//获取当前被选中的段
    segment1.tintColor = [UIColor greenColor];//边框和选中颜色
    [segment1 setBackgroundImage:[UIImage imageNamed:@"3"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    // UIControlStateNormal、UIBarMetricsDefault 设置成默认的就好
    [segment1 addTarget:self action:@selector(segmentchange) forControlEvents:UIControlEventValueChanged];
//触发事件
-(void)segmentchange{
    NSLog(@"分段被点击");
}
    [self.view addSubview:segment1];
   
    UISegmentedControl *s = [[UISegmentedControl alloc]initWithFrame:CGRectMake(50, 400, 100, 50)];
    [s insertSegmentWithTitle:@"分段" atIndex:3 animated:YES];
    [s insertSegmentWithTitle:@"函数" atIndex:0 animated:YES];//增加
    //[s removeSegmentAtIndex:0 animated:YES];//移除
    [self.view addSubview:s];
