1. UISwitch的定義
在ViewController.h中：
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: #008400}p.p6 {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}span.s8 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
{
//定義一個開關控件
//可以進行狀態的改變 兩種狀態：開、關 可以切換
//所有UIKit框架庫中的控件均以UI開頭
UISwitch* _mySwitch;
}
@property(retain,nonatomic) UISwitch* mySwitch;
@end
在ViewController.m的(void)viewDidLoad 中：
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}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; color: #4f8187}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s3 {font: 11.0px Menlo; 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-variant-ligatures: no-common-ligatures; color: #bb2ca2}
//創建一個開關對象，繼承于UIView的
_mySwitch = [[UISwitch alloc]init];
_mySwitch.frame=CGRectMake(100, 100, 80, 40); //寬高無法改變
//兩種方法開關狀態設置屬性，YES：開啟。NO：關閉
_mySwitch.on=YES; //點語法
[_mySwitch setOn:YES]; //set函數
//參數一：狀態設置
//參數二：是否開啟動畫
[_mySwitch setOn:YES animated:YES];
[self.view addSubview:_mySwitch];
2.開關外形的改變
- 默認外形：

- 設置開時的顏色
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; 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: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}
//設置開關顏色，默認為綠色
[_mySwitch setOnTintColor:[UIColor purpleColor]];

- 設置小圓鈕的顏色
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; 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: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}
//設置開關小圓鈕顏色
[_mySwitch setThumbTintColor:[UIColor blueColor]];
屏幕快照 2016-11-15 下午6.03.05.png
- 設置整體風格（邊框）顏色
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; 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: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}
//設置整體風格類型
[_mySwitch setTintColor:[UIColor orangeColor]];

3.添加按鈕函數
在ViewController.m的(void)viewDidLoad 中：
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; color: #008400}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}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: #000000}span.s5 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s7 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}
//向開關控件添加事件函數
//參數一：函數實現對象
//參數二：函數體
//參數三：事件響應時的事件類型 UIControlEventValueChanged：狀態發生變化,即從開到關或者從關到開
[_mySwitch addTarget:self action:@selector(swChange:) forControlEvents:UIControlEventValueChanged];
再去實現這個swChange函數：
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; color: #d12f1b}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: #703daa}span.s5 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s6 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s7 {font-variant-ligatures: no-common-ligatures; color: #000000}
//參數傳入就是開關本身 可以用來判斷開關狀態
-(void)swChange:(UISwitch*) sw
{
if (sw.on == YES) {
NSLog(@"open");
}
NSLog(@"blabla");
}
注意 如果想判斷按鈕狀態，需要傳入參數，參數就是按鈕本身
