iPhone datepicker instead of keyboard? - iphone

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 default? Note that there are also other elements on my form.

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

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 3

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

Answer 4

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

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]];
}
