IOS中最常用到的控件UIButton、UISlider、UISwitch、UISegmentedControl通过Xib文件拖动生成非常简单，其实用代码实现也是一样的简单，当然，用代码实现能够掌握到更多的东西。
上图中包涵提到的4种控件，UIButton按钮、UISlider滑块、UISwitch开关、UISegmentedControl分类
首先创建一个名为CodeControls的Empty Application项目
AppDelegate.h和AppDelegate.m文件中和IOS代码实现Hello World中的一样
MainViewController.h
- <span style="font-size:10px;">#import <UIKit/UIKit.h>
- @interface MainViewController : UIViewController
- @property (strong, nonatomic) UIButton *myBtn;
- @property (strong, nonatomic) UISlider *mySlider;
- @property (strong, nonatomic) UISwitch *mySwitch;
- @property (strong, nonatomic) UISegmentedControl *mySc;
- @end</span>
#import <UIKit/UIKit.h>
@interface MainViewController : UIViewController
@property (strong, nonatomic) UIButton *myBtn;
@property (strong, nonatomic) UISlider *mySlider;
@property (strong, nonatomic) UISwitch *mySwitch;
@property (strong, nonatomic) UISegmentedControl *mySc;
@end
MainViewController.m
- <span style="font-size:10px;">#import "MainViewController.h"
- @interface MainViewController ()
- @end
- @implementation MainViewController
- @synthesize myBtn,mySlider,mySwitch,mySc;
- - (void)viewDidLoad
- {
- // 加载UIView
- UIView *mainView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
- mainView.backgroundColor = [UIColor whiteColor];
- self.view = mainView;
- [mainView release];
- // 创建一个Button按钮
- UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
- btn.frame = CGRectMake(100, 30, 57, 57);
- [btn setTitle:@"Button" forState:UIControlStateNormal];
- [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
- [btn setBackgroundImage:[UIImage imageNamed:@"icon.png"] forState:UIControlStateNormal];
- [btn addTarget:self action:@selector(onClick:) forControlEvents:UIControlEventTouchUpInside];
- myBtn = btn;
- [self.view addSubview:myBtn];
- // 创建一个Slider划块按钮
- UISlider *slider = [[[UISlider alloc] initWithFrame:CGRectMake(50, 180, 200, 10)] autorelease];
- slider.minimumValue = 0.0f;
- slider.maximumValue = 100.0f;
- slider.value = 50.0f;
- [slider addTarget:self action:@selector(onChange:) forControlEvents:UIControlEventTouchUpInside];
- mySlider = slider;
- [self.view addSubview:mySlider];
- // 创建一个UISwitch开关按钮
- UISwitch *sbtn = [[[UISwitch alloc] initWithFrame:CGRectMake(50, 210, 200, 50)] autorelease];
- [sbtn addTarget:self action:@selector(onSwitch:) forControlEvents:UIControlEventTouchUpInside];
- mySwitch = sbtn;
- [self.view addSubview:mySwitch];
- // 创建一个UISegmentedControl
- NSArray *btnList = [NSArray arrayWithObjects:@"left",@"center",@"right", nil];
- UISegmentedControl *sc = [[[UISegmentedControl alloc] initWithItems:btnList] autorelease];
- sc.frame = CGRectMake(50, 250, 200, 60);
- [sc addTarget:self action:@selector(onSelect:) forControlEvents:UIControlEventTouchUpInside];
- mySc = sc;
- [self.view addSubview:mySc];
- [super viewDidLoad];
- }
- // 点击Button触发
- - (void)onClick:(id *)sender
- {
- }
- // 拉动Slider划块触发
- - (void)onChange:(id *)sender
- {
- }
- // 选择Switch触发
- - (void)onSwitch:(id *)sender
- {
- }
- // 选择UISegmentedControl触发
- - (void)onSelect:(id *)sender
- {
- }
- </span>
#import "MainViewController.h"
@interface MainViewController ()
@end
@implementation MainViewController
@synthesize myBtn,mySlider,mySwitch,mySc;
- (void)viewDidLoad
{
// 加载UIView
UIView *mainView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
mainView.backgroundColor = [UIColor whiteColor];
self.view = mainView;
[mainView release];
// 创建一个Button按钮
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(100, 30, 57, 57);
[btn setTitle:@"Button" forState:UIControlStateNormal];
[btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[btn setBackgroundImage:[UIImage imageNamed:@"icon.png"] forState:UIControlStateNormal];
[btn addTarget:self action:@selector(onClick:) forControlEvents:UIControlEventTouchUpInside];
myBtn = btn;
[self.view addSubview:myBtn];
// 创建一个Slider划块按钮
UISlider *slider = [[[UISlider alloc] initWithFrame:CGRectMake(50, 180, 200, 10)] autorelease];
slider.minimumValue = 0.0f;
slider.maximumValue = 100.0f;
slider.value = 50.0f;
[slider addTarget:self action:@selector(onChange:) forControlEvents:UIControlEventTouchUpInside];
mySlider = slider;
[self.view addSubview:mySlider];
// 创建一个UISwitch开关按钮
UISwitch *sbtn = [[[UISwitch alloc] initWithFrame:CGRectMake(50, 210, 200, 50)] autorelease];
[sbtn addTarget:self action:@selector(onSwitch:) forControlEvents:UIControlEventTouchUpInside];
mySwitch = sbtn;
[self.view addSubview:mySwitch];
// 创建一个UISegmentedControl
NSArray *btnList = [NSArray arrayWithObjects:@"left",@"center",@"right", nil];
UISegmentedControl *sc = [[[UISegmentedControl alloc] initWithItems:btnList] autorelease];
sc.frame = CGRectMake(50, 250, 200, 60);
[sc addTarget:self action:@selector(onSelect:) forControlEvents:UIControlEventTouchUpInside];
mySc = sc;
[self.view addSubview:mySc];
[super viewDidLoad];
}
// 点击Button触发
- (void)onClick:(id *)sender
{
}
// 拉动Slider划块触发
- (void)onChange:(id *)sender
{
}
// 选择Switch触发
- (void)onSwitch:(id *)sender
{
}
// 选择UISegmentedControl触发
- (void)onSelect:(id *)sender
{
}
