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,

1、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:

     topbarview.backgroundcolor = [uicolor orangecolor];
     [self addsubview:topbarview];
 
     _btnconfirm = [[uibutton alloc] initwithframe:cgrectmake(self.frame.size.width-kbutton_width-10, 0, kbutton_width, kbutton_height)];
     [_btnconfirm addtarget:self action:@selector(btnconfirm:) forcontrolevents:uicontroleventtouchupinside];
     [_btnconfirm settitle:@ "确定" forstate:uicontrolstatenormal];
     [topbarview addsubview:_btnconfirm];
 
     _btncancel = [[uibutton alloc] initwithframe:cgrectmake(10, 0, kbutton_width, kbutton_height)];
     [_btncancel addtarget:self action:@selector(btncancel:) forcontrolevents:uicontroleventtouchupinside];
     [_btncancel settitle:@ "取消" forstate:uicontrolstatenormal];
     [topbarview addsubview:_btncancel];
 
     _datepicker = [[uidatepicker alloc] initwithframe:cgrectmake(0, cgrectgetmaxy(topbarview.frame), self.frame.size.width, self.frame.size.height-ktopbarviewheight)];
     _datepicker.backgroundcolor = [uicolor whitecolor];
     [self addsubview:_datepicker];
 
   }
   return self;
}
 
- ( void )btnconfirm:(id)sender
{
   if (self.selectblock) {
     self.selectblock(self.datepicker.date);
   }
}
 
- ( void )btncancel:(id)sender
{
   if (self.selectblock) {
     self.selectblock(nil);
   }
}
 
+ (ycdatepickerview *)datepickerviewwithmode:(uidatepickermode) datepickermode bolck:(mybasicblock)block
{
   ycdatepickerview *picker = [[ycdatepickerview alloc] initwithframe:cgrectmake(0, 0, screen_width, kdatepicker_height)];
   picker.datepicker.datepickermode = datepickermode;
   picker.selectblock = block;
   return picker;
}
 
@end

2、ycdatepickerview的使用 。

1、在viewcontroller中导入头文件 。

?

                              bolck:^(nsdate *result) {
                                if (result) {
                                  begin.text = [weakself datetostring:result];
                                }
                                [begin resignfirstresponder];

//日期转为字符串

   return strdate;
}
 
@end
