typedef NS_ENUM(NSInteger, UIDatePickerMode) {
    UIDatePickerModeTime,           // Displays hour, minute, and optionally AM/PM designation depending on the locale setting (e.g. 6 | 53 | PM)
    UIDatePickerModeDate,           // Displays month, day, and year depending on the locale setting (e.g. November | 15 | 2007)
    UIDatePickerModeDateAndTime,    // Displays date, hour, minute, and optionally AM/PM designation depending on the locale setting (e.g. Wed Nov 15 | 6 | 53 | PM)
    UIDatePickerModeCountDownTimer, // Displays hour and minute (e.g. 1 | 53)
}

官方的UIDatePicker只有四种模式，不能选到秒。
变态的需求必须要精确到秒，就自定义了一个。

思路

定义多个UIPickerView，用来选择年-月-日时:分:秒。注意tag区分每个pickerView，设置好dataSource和delegate
每个pickerView显示1个component，多行row供选择。

#import <UIKit/UIKit.h>

@protocol WJDatePickerDelegate;
@interface WJDatePicker : UIView

@property (nonatomic, retain) NSDate*   date;       // 当前date
@property (nonatomic, strong) NSString* dateString;

/**
 * 设置默认值为当前时间
 */
-(void)resetDateToCurrentDate;

/**
 * 设置提示信息
 */
-(void)setHintsText:(NSString*)hints;
/**
 * 点击确定按钮
 */
-(IBAction)actionEnter:(id)sender;
@property (nonatomic, assign) id<WJDatePickerDelegate>delegate;
@end

@protocol WJDatePickerDelegate <NSObject>
/**
 * 代理  点击确定后的事件
 */
@optional
-(void)DatePickerDelegateEnterActionWithDataPicker:(WJDatePicker*)picker;
@end

.m实现

#import "WJDatePicker.h"
#import "NSDate+FSExtension.h"

typedef enum {
    ePickerViewTagYear = 2016,
    ePickerViewTagMonth,
    ePickerViewTagDay,
    ePickerViewTagHour,
    ePickerViewTagMinute,
    ePickerViewTagSecond
}PickViewTag;

@interface WJDatePicker () <UIPickerViewDataSource,UIPickerViewDelegate>
@property (nonatomic, retain) UIPickerView* yearPicker;     // 年
@property (nonatomic, retain) UIPickerView* monthPicker;    // 月
@property (nonatomic, retain) UIPickerView* dayPicker;      // 日
@property (nonatomic, retain) UIPickerView* hourPicker;     // 时
@property (nonatomic, retain) UIPickerView* minutePicker;   // 分
@property (nonatomic, retain) UIPickerView* secondPicker;

@property (nonatomic, retain) UIToolbar*    toolBar;        // 工具条
@property (nonatomic, retain) UILabel*      hintsLabel;     // 提示信息

// dataSource
@property (nonatomic, retain) NSMutableArray* yearArray;
