datepicker 및 textfields

Question

저는 ios 개발에 익숙하며 날짜 선택 도구에서 날짜를 가져 오는 두 개의 텍스트 필드를 설정하는 방법을 알아야합니다.

.H 파일

#import <UIKit/UIKit.h> 

@interface DatePickerForTermins : UIViewController<UITextFieldDelegate> 
{ 
    //NSDate *frmDate; 
    UIActionSheet *dateSheet; 
    UIActionSheet *dateSheet2; 





} 

@property (weak, nonatomic) IBOutlet UITextField *fromDateTextField; 
@property (weak, nonatomic) IBOutlet UITextField *toDateTextField; 

@property (weak, nonatomic) IBOutlet UILabel *chosenFromDateLabel; 
@property (weak, nonatomic) IBOutlet UILabel *chosenToDateLabel; 

@property (weak, nonatomic) NSDate *frmDate; 
@property (weak, nonatomic) NSDate *toDate; 

-(void)setDateFRM; 
-(void)dismissDateSet; 
-(void)cancelDateSet; 
-(void)setDateTO; 
-(void)dismissDateSet2; 
-(void)cancelDateSet2; 
@end

다른 텍스트 필드 그냥 대신 날짜 선택기의 일반 키보드를 제공 여기에 코드입니다. 아무도 이것을 어떻게 수행 할 수 있는지 아니?

Answer 1

날짜가 변경되면 "addTarget"을 사용하여 메시지를 가져옵니다.

예 :

[rmDatePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged|; 
... 

-(void) datePickerValueChanged:(id) sender { 
    UIDatePicker *picker = (UIDatePicker*)sender; 
    NSDate dateFromPicker = picker.date; 
    fromDateTextField.text = [dateFromPicker description]; 
}
