IOS——模仿Android界面实现单选框UICheckBoxButton

首先要吐槽一下，IOS好好的Switch不用，非得要模仿Android搞一个单选框什么的最讨厌了啊啊啊啊啊啊啊啊~！！！！！

好吧，现在开始，实现自定义的模仿Android单选框的类命名为UICheckBoxButton，继承于UIControl

该UICheckbox功能：

1. 自定义选项的名字

2. 自定义选项框的大小（定义高度，因为选项框为正方形）

3. 自定义选项框的长度

4. 监听选项框的点击事件

上代码：

1. UICheckBoxButton.h

#import <UIKit/UIKit.h>@interface UICheckBoxButton : UIControl{    NSString *checkedImage;    NSString *uncheckedImage;    UIImageView *backgroundImage;    UILabel  *titleLabel;    BOOL     isChecked;    id       delegate;}@property (retain, nonatomic) UIImageView *backgroundImage;@property (retain, nonatomic) UILabel *titleLabel;@property (retain, nonatomic) id  delegate;- (id)initWithContent:(NSString *)titleName;- (void)setOffsetFrame:(CGRect)frame;- (BOOL)getChekced;@end

2. UICheckBoxButton.m

#import "UICheckBoxButton.h"@implementation UICheckBoxButton@synthesize backgroundImage;@synthesize titleLabel;@synthesize delegate;- (id)initWithContent:(NSString *)titleName {    self = [super init];    [self setBackgroundColor:[UIColor clearColor]];        [self initImages];        titleLabel = [[UILabel alloc] init];    [titleLabel setText:titleName];    [titleLabel setFont:[UIFont systemFontOfSize:14]];    [titleLabel setTextColor:[UIColor whiteColor]];    [titleLabel setBackgroundColor:[UIColor clearColor]];        backgroundImage = [[UIImageView alloc] init];    isChecked = NO;    [backgroundImage setImage:[UIImage imageNamed:uncheckedImage]];    [self addSubview:backgroundImage];    [self addSubview:titleLabel];    [self addTarget:self action:@selector(clickEvent) forControlEvents:UIControlEventTouchUpInside];    return self;}- (void)initImages {    checkedImage = @"checkedIcon.png";    uncheckedImage = @"uncheckedIcon.png";}- (void)setOffsetFrame:(CGRect)frame {    CGSize frameSize;    frameSize.width = frame.size.width;    frameSize.height = frame.size.height;    [super setFrame:CGRectMake(frame.origin.x, frame.origin.y, frameSize.width, frameSize.height)];        CGRect iconFrame;    iconFrame.size = CGSizeMake(frameSize.height,frameSize.height);    iconFrame.origin.x = 0;    iconFrame.origin.y = 0;    [backgroundImage setFrame:iconFrame];        CGRect lbFrame;    lbFrame.size = CGSizeMake(frameSize.width, frameSize.height);    lbFrame.origin.x = frame.size.height+5;    lbFrame.origin.y = 0;    [titleLabel setFrame:lbFrame];}- (void)clickEvent {    if (isChecked) {        isChecked=NO;        [backgroundImage setImage:[UIImage imageNamed:uncheckedImage]];    } else {        isChecked=YES;        [backgroundImage setImage:[UIImage imageNamed:checkedImage]];    }    [self sendActionsForControlEvents:UIControlEventValueChanged];}-(BOOL)getChekced{    return isChecked;}@end

注意，image有两张，一张是选中的图片，另一张是没选中的图片。

这里贴上我自制的图片

3. 使用UICheckBoxButton

首先，

#import "UICheckBoxButton.h"

然后实现代码：

    dirveCheckbox=[[UICheckBoxButtonalloc]initWithContent:@"Test"];//初始化checkbox的名称

    [dirveCheckboxsetOffsetFrame:CGRectMake(10,230,120,28)];//初始化checkbox的位置，其中120为长度，28为高度

    [dirveCheckboxaddTarget:selfaction:@selector(CheckBoxClicked:)forControlEvents:UIControlEventValueChanged];//给予checkbox点击事件监听

checkbox点击事件的监听方法：

-(void)CheckBoxClicked:(UICheckBoxButton *)checkbox{

    NSLog(@"click check box");

}

呼呼，完成！
