IOS自訂view——swtichbutton開關

============================================================博文原創，轉載請聲明出處電子咖啡(原id藍岩)============================================================

IOS中沒有工具列，是和android的有一差別，不適應，現在我們自己來實現開關

首先在你的資源裡面添加2張圖片，表示開、關的狀態，分別命名：switch_off.png，switch_on.png，下面上代碼，相信你看得懂。，如有疑問，歡迎留言交流。

UICustomSwitch.h

#import <UIKit/UIKit.h>@interface UICustomSwitch : UIButton@end

UICustomSwitch.m

#import "UICustomSwitch.h"@implementation UICustomSwitch- (id)initWithFrame:(CGRect)frame{    self = [super initWithFrame:frame];    if (self) {        [self setBackGroundImage];    }    return self;}- (void)setBackGroundImage {    [self setBackgroundImage:[UIImage imageNamed:@"switch_off.png"] forState:UIControlStateNormal];    [self setBackgroundImage:[UIImage imageNamed:@"switch_on.png"] forState:UIControlStateSelected];            [self addTarget:self action:@selector(touchUIInside:) forControlEvents:UIControlEventTouchUpInside];    self.selected = NO;}-(id)initWithCoder:(NSCoder *)aDecoder{    self =  [super initWithCoder:aDecoder];    if (self) {        [self setBackGroundImage];    }    return self;}-(IBAction)touchUIInside:(id)sender{    UICustomSwitch* sw= (UICustomSwitch*)sender;    sw.selected = !sw.selected;      }@end
