iPhone datepicker zamiast klawiatury?
Jak byś to zrobił?
Mam formularz z UITextField. Po kliknięciu w niego chciałbym wyświetlić UIDatePicker zamiast domyślnej klawiatury, która wyskakuje domyślnie? Zauważ, że w moim formularzu są również inne elementy.

Myślę, że jest to bardziej oficjalny sposób, aby to zrobić:
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
datePicker.tag = indexPath.row;
textField.inputView = datePicker;

W .h
UIDatePicker *datePicker;
NSDate *date;
UIToolbar *keyboardToolbar;
W ViewDidLoad:
if (keyboardToolbar == nil) {
keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
[keyboardToolbar setBarStyle:UIBarStyleBlackTranslucent];
UIBarButtonItem *extraSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *accept = [[UIBarButtonItem alloc] initWithTitle:@"Accept" style:UIBarButtonItemStyleDone target:self action:@selector(closeKeyboard:)];
[keyboardToolbar setItems:[[NSArray alloc] initWithObjects: extraSpace, accept, nil]];
}
self.txtDate.inputAccessoryView = keyboardToolbar;
datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
self.txtDate.inputView = datePicker;
- (void)datePickerValueChanged:(id)sender{
date = datePicker.date;
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"dd/MM/YYYY"];
[self.txtDate setText:[df stringFromDate:date]];
}
W storyboard Dodaj do txtDate - > EditingDidEnd
- (IBAction)establishHour:(id)sender{
hour = hourPicker.date;
NSDateFormatter *hf = [[NSDateFormatter alloc] init];
[hf setDateFormat:@"HH:MM"];
[self.txtHour setText:[hf stringFromDate:hour]];
}
Ustawia klawiaturę jako DatePicker i tworzy pasek narzędzi z przyciskiem akceptującym zaznaczenie.

Przekonwertowałem odpowiedź Johana Koola na swift, jeśli ktoś by chciał. Umieściłem kod w viewDidLoad.
let datePicker = UIDatePicker()
datePicker.datePickerMode = UIDatePickerMode.Date
datePicker.addTarget(self, action: "datePickerValueChanged:", forControlEvents: UIControlEvents.ValueChanged)
textField.inputView = datePicker

Dodano w .pliki h:
UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>
Dodano w .pliki m:
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
pTxtDate.text = [NSString stringWithFormat:@"%@",
[df stringFromDate:[NSDate date]]];
NSLog(@"pTxtDate.text %@",pTxtDate.text);
[df release];
[self.view addSubview:pTxtDate];
[pTxtDate release];
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];
[self.view addSubview:DatePicker];
[DatePicker release];
}
- (void)LabelChange:(id)sender {
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
pTxtDate.text = [NSString stringWithFormat:@"%@",
[df stringFromDate:DatePicker.date]];
}
