1. 定义步进器和分栏控制器
在ViewController.h中定义对象和声明属性：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #d12f1b}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #bb2ca2}span.s1 {font-variant-ligatures: no-common-ligatures; color: #78492a}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s4 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s6 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s7 {font-variant-ligatures: no-common-ligatures; color: #000000}
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
{
//定义步进器对象，按照一定的数值来调整某个数据
UIStepper* _stepper;
//定义分栏控制器
UISegmentedControl* _segControl;
}
@property(retain, nonatomic) UIStepper* stepper;
@property(retain, nonatomic) UISegmentedControl* segControl;
@end
在ViewController.m中同步属性：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}span.s1 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s4 {font-variant-ligatures: no-common-ligatures; color: #4f8187}
//同步属性
@synthesize segControl = _segControl;
@synthesize stepper = _stepper;
2. 步进器
在ViewController.m的viewDidLoad中添加：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s5 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s6 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s7 {font-variant-ligatures: no-common-ligatures; color: #272ad8}span.s8 {font-variant-ligatures: no-common-ligatures; color: #008400}span.s9 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #008400}span.s10 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s11 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s12 {font: 11.0px 'Apple Color Emoji'; font-variant-ligatures: no-common-ligatures}span.s13 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}
//创建步进器对象
_stepper=[[UIStepper alloc]init];
_stepper.frame = CGRectMake(100, 100, 80, 40); //宽高不能变更
_stepper.minimumValue=0;
_stepper.maximumValue=100;
_stepper.stepValue=5;
_stepper.value=10; //设置当前值，默认为0
_stepper.tintColor=[UIColor yellowColor];
_stepper.backgroundColor=[UIColor blackColor];
//是否可以重复响应事件(按住➕能不能一直加，而且越来越快，还是需要松开再按)
_stepper.autorepeat=YES;
//是否将步进结果通过事件函数每一次都响应出来
_stepper.continuous=YES;
//添加事件函数
[_stepper addTarget:self action:@selector(stepChange) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:_stepper];
在函数外实现事件函数：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #d12f1b}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}
-(void)stepChange
{
NSLog(@"value=%f",_stepper.value);
}

3. 分栏控制器
在ViewController.m的viewDidLoad中添加：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p7 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #4f8187}span.s1 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s4 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s5 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s7 {font-variant-ligatures: no-common-ligatures; color: #272ad8}span.s8 {font-variant-ligatures: no-common-ligatures; color: #008400}span.s9 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #008400}span.s10 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s11 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s12 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s13 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}
//创建分栏控件
_segControl=[[UISegmentedControl alloc]init];
_segControl.frame=CGRectMake(10, 200, 300, 40); //宽度可变，高度不可变
//添加两个个按钮元素
[_segControl insertSegmentWithTitle:@"0 dollar" atIndex:0 animated:NO];
[_segControl insertSegmentWithTitle:@"5 dollar" atIndex:1 animated:NO];
//当前默认按钮索引设置
_segControl.selectedSegmentIndex=0;
[_segControl addTarget:self action:@selector(segChange) forControlEvents:UIControlEventValueChanged];
_segControl.tintColor=[UIColor orangeColor];
_segControl.backgroundColor=[UIColor yellowColor];
[self.view addSubview:_segControl];
在函数外实现事件函数：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}
-(void)segChange
{
NSLog(@"%l",_segControl.selectedSegmentIndex);
}
默认样式
设置主体颜色橘色，背景颜色黄色：
