    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。

    .h

    #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"
