UiDatePicker Xcode 6에서 레이블에 현재 날짜가 표시되지 않고 완료 또는 취소 버튼이 표시되지 않습니다.

Question

사람들 현재 날짜를 선택할 수없는 datepicker를 어떻게 구현했는지 알 수 없습니다. 나 또한 날짜 피커가 튀어 오를 때 완료된 버튼을 보여주기 위해 많은 답을 따랐다.

기본적으로 완료 버튼과 현재 날짜의 라벨 설정에 도움이됩니다. 여기

다음 코드를 대신 UILabel의의의 UITextField를 이용할 수 있도록 스크린 샷

- (IBAction)btnDate:(id)sender { 
datepicker=[[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 325, 300)]; 
datepicker.datePickerMode = UIDatePickerModeDate; 
datepicker.hidden = NO; 
datepicker.date = [NSDate date]; 

[datepicker addTarget:self 
       action:@selector(LabelChange:) 
    forControlEvents:UIControlEventValueChanged]; 
datepicker.backgroundColor = [UIColor whiteColor]; 
[self.view addSubview:datepicker]; //this can set value of selected date to your label change according to your condition 


NSDateFormatter * df = [[NSDateFormatter alloc] init]; 
[df setDateFormat:@"M-d-yyyy"]; // from here u can change format.. 
lblDate.text=[df stringFromDate:datepicker.date]; 

}

- (void)LabelChange:(id)sender{ 
    NSDateFormatter *df = [[NSDateFormatter alloc] init]; 
    [df setDateFormat:@"M-d-yyyy"]; 
    lblDate.text = [NSString stringWithFormat:@"%@", 
          [df stringFromDate:datepicker.date]]; 
    [datepicker removeFromSuperview]; 

} 

Answer 1

이 유용한 자습서로 저의 질문에 대한 답을 찾았습니다. 다음은 코드 선택기 아래에있는 링크에서 가져온 취소 버튼을 사용하여 날짜 선택기를 사용하여 작성자에게 자세한 정보와 크레딧을 제공하려는 사용자가 사용할 수있는 코드입니다. 같은 날짜 선택기에 하위 뷰로있는 UIButton을 추가 할 수

iOS – How To Make DatePicker

Answer 2

시도이다 : 이런 식으로

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 

    // Create date picker 

    UIDatePicker * datePicker = [UIDatePicker new]; 

    // Create and configure toolbar 

    UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.frame), 44)]; 

    UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone 
                       target:self 
                       action:@selector(doneAction:)]; 
    UIBarButtonItem* cancelButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel 
                        target:self 
                        action:@selector(cancelAction:)]; 
    UIBarButtonItem* flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 
                       target:nil 
                       action:nil]; 
    [toolbar setItems:@[cancelButton, flexibleSpace, doneButton]]; 

    // Set date picker as input view 

    self.textField.inputView = datePicker; 

    // Set toolbar as accessory view 

    self.textField.inputAccessoryView = toolbar; 
} 

- (void)doneAction:(id)sender 
{ 
    UIDatePicker* datePicker = (UIDatePicker*)[self.textField inputView]; 
    self.textField.text = datePicker.date.description; 
    [self.textField resignFirstResponder]; 
} 

- (void)cancelAction:(id)sender 
{ 
    [self.textField resignFirstResponder]; 
}
