一、封裝日期選擇器類YCDatePickerView

1、新建一個(gè)類，基于UIView，取名YCDatePickerView。

2、YCDatePickerView類中.h文件代碼如下：

typedef void (^MyBasicBlock)(id result);

#import 

@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類中.m文件代碼如下：

#define SCREEN_WIDTH   [[UIScreen mainScreen] bounds].size.width
#define SCREEN_HEIGHT   [[UIScreen mainScreen] bounds].size.height

#define kTopBarViewHeight    40
#define kButton_Width      40
#define kButton_Height     40
#define kDatePicker_Height   256


#import "YCDatePickerView.h"

@implementation YCDatePickerView

- (id)initWithFrame:(CGRect)frame
{
  self = [super initWithFrame:frame];
  if (self) {

    UIView *topBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, kTopBarViewHeight)];
    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:@"確定" 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

二、YCDatePickerView的使用

1、在ViewController中導(dǎo)入頭文件

#import "YCDatePickerView.h"

2、在ViewController.m中添加如下代碼

#define SCREEN_WIDTH   [[UIScreen mainScreen] bounds].size.width
#define SCREEN_HEIGHT   [[UIScreen mainScreen] bounds].size.height


#import "ViewController.h"
#import "YCDatePickerView.h"

@interface ViewController ()

@property (retain, nonatomic) YCDatePickerView *datePicker;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];


  UITextField *begin = [[UITextField alloc] initWithFrame:CGRectMake(10, 70, SCREEN_WIDTH-20, 30)];
  begin.placeholder = @"請(qǐng)輸入開始時(shí)間";
  begin.borderStyle = UITextBorderStyleRoundedRect;
  [self.view addSubview:begin];

  __weak ViewController *weakself = self;
  begin.inputView = [YCDatePickerView datePickerViewWithMode:UIDatePickerModeDate
                             bolck:^(NSDate *result) {
                               if (result) {
                                 begin.text = [weakself dateToString:result];
                               }
                               [begin resignFirstResponder];
                             }];


  UITextField *end = [[UITextField alloc] initWithFrame:CGRectMake(10, 120, SCREEN_WIDTH-20, 30)];
  end.placeholder = @"請(qǐng)輸入結(jié)束時(shí)間";
  end.borderStyle = UITextBorderStyleRoundedRect;
  [self.view addSubview:end];

  end.inputView = [YCDatePickerView datePickerViewWithMode:UIDatePickerModeDate
                                   bolck:^(NSDate *result) {
                                     if (result) {
                                       end.text = [weakself dateToString:result];
                                     }
                                     [end resignFirstResponder];
                                   }];

}

//日期轉(zhuǎn)為字符串
- (NSString *)dateToString:(NSDate *)date
{
  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
  NSString *strDate = [dateFormatter stringFromDate:date];
  return strDate;
}

@end
