默认情况下，当我在其余应用程序中创建UIDate选择器时，当我单击完成时，必须默认输入当前时间，或者如果日期选择器已设置动画，则日期值可以更改，但在我的情况下，默认情况下不返回当前时间！请帮忙，1.My RemainderSetUpViewcontroller.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;
@property (strong, nonatomic)IBOutlet NSString *index;
@property(strong, nonatomic) id <RemainderDelegate> delegate;
-(void)addRemainder;
-(void)actionDone;
@end
`
