iOS开发系列之常用自定义控件开发集—自定义单选按钮或者多选按钮控件开发

在我们实际开发中我们做登陆或者注册功能时往往需要勾选某个协议这个时候就需要用到CheckBox按钮，CheckBox是pc或者android上得控件ios没有，所以需要我们自定义。
WHC_RadioButton.h头文件如下：

////  WHC_RadioButton.h//  CTBMobileBank////  Created by 吴海超 on 15/4/1.////#import <UIKit/UIKit.h>#define KWHC_IMAGE_SIZE (15.0)    //图标尺寸@interface WHC_RadioButton : UIButton@end

WHC_RadioButton.m源文件如下：

////  WHC_RadioButton.m//  CTBMobileBank////  Created by 吴海超 on 15/4/1.////#import "WHC_RadioButton.h"@implementation WHC_RadioButton//处理按钮标题区域- (CGRect)titleRectForContentRect:(CGRect)contentRect{    contentRect.origin.x = KWHC_IMAGE_SIZE;    return contentRect;}//处理图标区域- (CGRect)imageRectForContentRect:(CGRect)contentRect{    CGRect  rect = CGRectZero;    rect.origin.x = 0.0;    rect.origin.y = (CGRectGetHeight(self.bounds) - KWHC_IMAGE_SIZE) / 2.0;    rect.size.height = KWHC_IMAGE_SIZE;    rect.size.width = KWHC_IMAGE_SIZE;    return rect;}@end
