iPhone datepicker instead of keyboard?

Question

How would you do that?

I have a form with a UITextField. When I click in it I would like to display a UIDatePicker instead of the default Keyboard that pops-up by de

Answer 1

I think this is a more official way to do this:

UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
datePicker.tag = indexPath.row;
textField.inputView = datePicker;

Answer 2

I've converted Johan Kool's answer into swift if anyone would like it. I placed the code in viewDidLoad.

let datePicker = UIDatePicker()
datePicker.datePickerMode = UIDatePickerMode.Date
datePicker.addTarget(self, action: "datePickerValueChanged:", forControlEvents: UIControlEvents.ValueChanged)
textField.inputView = datePicker

Added in .h files :

UIViewController <UIPickerViewDelegate, UIPickerViewDataSource> 

Added in .m files :

{

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]];

}

in .h

UIDatePicker *datePicker;
NSDate *date;
UIToolbar *keyboardToolbar;

in 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]];
}

in storyboard add to txtDate -> EditingDidEnd

- (IBAction)establishHour:(id)sender{

hour = hourPicker.date;

NSDateFormatter *hf = [[NSDateFormatter alloc] init];
[hf setDateFormat:@"HH:MM"];

[self.txtHour setText:[hf stringFromDate:hour]];

}

Sets the keyboard as DatePicker and created a toolbar with a button to accept the selection.

Answer 5

(IBAction)estableceHora:(id)sender{
   Hora = horaPicker.date;
   NSDateFormatter *hf = [[NSDateFormatter alloc] init];
   [hf setDateFormat:@"HH:MM"];
   [self.txtHora setText:[hf stringFromDate:Hora]];
}
