前言
封装了一个日期选择器，解决两个问题：
1、点击textfield，键盘弹出和日期选择器弹出的逻辑处理；
2、同一个界面需要多次用到日期选择器时，判断点击的textfield;
一、封装日期选择器类ycdatepickerview
1、新建一个类，基于uiview，取名ycdatepickerview。
2、ycdatepickerview类中.h文件代码如下：

typedef void (^mybasicblock)(id result);
#import <uikit/uikit.h>
@interface ycdatepickerview : uiview
@property (nonatomic, strong) uibutton *btnconfirm;
@property (nonatomic, strong) uibutton *btncancel;
@property (nonatomic, strong) uidatepicker *datepicker;
@property (nonatomic, copy) mybasicblock selectblock;
+ (ycdatepickerview *)datepickerviewwithmode:(uidatepickermode) datepickermode bolck:(mybasicblock)block;
@end

3、ycdatepickerview类中.m文件代码如下：

}

二、ycdatepickerview的使用
1、在viewcontroller中导入头文件
|
1
|
#import "ycdatepickerview.h"
|
2、在viewcontroller.m中添加如下代码
