デフォルトUIDateでは、残りのアプリでピッカーを作成しているときに、完了をクリックすると、デフォルトで現在の時刻を入力する必要があります。または、日付ピッカーがアニメーション化されている場合、日付の値は変更できますが、私の場合、現在の時刻はデフォルトで返されません! 助けてください、1.私のReminderSetUpViewcontroller.h `

@protocol RemainderDelegate <NSObject>
-(void)store:(NSArray *) remainderDel:(NSArray *) TimeDateDel;
@end

@interface RemainderSetUpViewcontroller : UIViewController<UITextFieldDelegate,UITextFieldDelegate>
{

    UITextField *textField1;
    NSString *str;
    UIDatePicker *datePicker;
    NSDate *date;
    NSMutableArray *remainder;
    NSMutableArray *TimeDate;
    UILocalNotification* notification;
}

@property (strong, nonatomic)IBOutlet NSString* remainderr;

コード内の行の後に 1 行追加するだけです

datePicker.datePickerMode = UIDatePickerModeDateAndTime;

以下の行をコードに追加して試してください

datePicker.date=[NSDate date];
