UIControl 控制类
addTarget:forcontrolEvents：添加响应事件（满足什么条件下 让某人调用什么方法）
UISegegmentedControl(分段控制器)
UISegmentedControl *seg = [[UISegmentedControl alloc] initWithItems:@[@"消息",@"电话",@"微信"]];
seg.frame=CGRectMake(100,50,200,40);
[self.viewaddSubview:seg];
[segrelease];
选中分段下标
seg.selectedSegmentIndex=0;//(从0开始)
背景颜色
seg.backgroundColor = [UIColor blackColor];
渲染颜色
seg.tintColor= [UIColorlightGrayColor];
插入新的分段
[seg insertSegmentWithTitle:@"陌陌" atIndex:2 animated:YES];
添加响应事件(通过下标值得变化触发方法)
[segaddTarget:selfaction:@selector(segAction:) forControlEvents:UIControlEventValueChanged];
两个页面
self.redView= [[UIViewalloc]initWithFrame:CGRectMake(40,160,250,250)];
self.redView.backgroundColor=[UIColorredColor];
[self.viewaddSubview:self.redView];
[_redViewrelease];
green
self.greenView= [[UIViewalloc]initWithFrame:CGRectMake(40,160,250,250)];
self.greenView.backgroundColor=[UIColoryellowColor];
[self.viewaddSubview:self.greenView];
[_greenViewrelease];
/******** UISilder滑块控制器*********/
UISlider*sl = [[UISlideralloc]initWithFrame:CGRectMake(50,420,250,50)];
sl.backgroundColor= [UIColororangeColor];
[self.viewaddSubview:sl];
[slrelease];
颜色设置
划过距离的颜色
sl.minimumTrackTintColor= [UIColorcyanColor];
为划过距离的颜色(滑块右)
sl.maximumTrackTintColor= [UIColorblueColor];
滑块颜色
sl.thumbTintColor= [UIColorlightGrayColor];
添加响应事件
[sladdTarget:selfaction:@selector(slideAction:) forControlEvents:UIControlEventValueChanged];
滑动范围
最小值
sl.minimumValue= -100;
最大值
sl.maximumValue=1000;
更新滑块起始点
sl.value= -100;
/************ UIPageControl页码控制器************/
UIPageControl*pc = [[UIPageControlalloc]initWithFrame:CGRectMake(50,100,100,50)];
pc.backgroundColor= [UIColorblackColor];
[self.viewaddSubview:pc];
[pcrelease];
//页数
pc.numberOfPages=4;
//当前页
pc.currentPage=3;
//颜色(小点)
pc.pageIndicatorTintColor= [UIColorredColor];
//当前页颜色
pc.currentPageIndicatorTintColor= [UIColoryellowColor];
//响应事件
[pcaddTarget:selfaction:@selector(pageAction:)forControlEvents:UIControlEventValueChanged];
/************ UISwitch开关控制器************/
UISwitch*sw = [[UISwitchalloc]initWithFrame:CGRectMake(200,110,100,50)];
sw.backgroundColor= [UIColorwhiteColor];
[self.viewaddSubview:sw];
[swrelease];
//开关属性
sw.on=YES;
//开启时颜色
sw.onTintColor= [UIColorlightGrayColor];
//关闭时颜色
sw.tintColor= [UIColorcyanColor];
//按钮颜色
sw.thumbTintColor= [UIColorbrownColor];
//响应方法
[swaddTarget:selfaction:@selector(swAction:) forControlEvents:UIControlEventValueChanged];
}

获取视图对象的方式
1.tag值
2.属性
if(seg.selectedSegmentIndex==0) {
transition过渡动画
参数1:开始视图
参数2:结束视图
//参数3:持续时间
//参数4:动画选项
//参数5:完成动画之后调用的block
