uidatepicker

Just barely getting into iOS development using swift and getting a little overwhelmed sometimes trying to look at documentation and understand it. I am also currently running through Simon Allardice's iOS app development with swift essential training on Lynda.com and had a question regarding one of the objects we have instantiated in the WhatDay example. We basically are setting up a UIDatePicker object from which we are extracting what day of the week we are looking at with the NSDateFormatter object at which point I was wondering, which property would we need to access to get ahold of the

I am just trying to make a timer. I would like to use UIDatePickerModeCountDownTimer mode of the UIDatePicker , so that when the user simply selects say 15 mins in the picker, they are passed back to a screen that shows the value of 15 mins in a label that they can then count down from. As I have tried to get the value from the DatePicker, I realized that the picker passes back an NSTimeInterval that gets the current time in seconds: UIDatePicker *pickerView = [[UIDatePicker alloc] init]; NSTimeInterval new = (NSTimeInterval)pickerView.countDownDuration; So all I want is to know the value that

The following code is to show my UIDatepicker: - (IBAction)showActionSheet:(id)sender { NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? @"\n\n\n\n\n\n\n\n\n" : @"\n\n\n\n\n\n\n\n\n\n\n\n" ; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat:@"%@%@", title, NSLocalizedString(@"Please Select A Date", @"")] delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"I've Made My Choice", nil]; [actionSheet showInView:self.view]; UIDatePicker *datePicker = [[[UIDatePicker alloc] init]

Can u please tell me how to extract a date from UIDatePicker, i have extracted the month but i am not able to extract the date,Please help me out Thank You The NSDate object can be extracted by just accessing the date property of the object: NSDate *dateFromPicker = [someDatePicker date]; If you want to extract detailed information about what month, day and year a person has chosen, this is a little bit more complex (but just a little bit). The solution is to use an NSCalendar reference - it is likely that you'd want to use Gregorian. NSCalendar *calendar = [[NSCalendar alloc]

I'm having trouble here. Took me hours but no use. Please keep in mind I checked the heck of StackOverFlow for a fix but there isn't any. When I convert the _date Object from Gregorian to Hijri it does not convert. I know that because when I print it it still gives me the Gregorian day. This troubles me because I want to setDate of a UIDatePicker and it's setting it incorrectly because the _date is gregorian and my UIDatePicker object calendar set to setCalendar:_hijriCalendar //DATE SETTING _date = [NSDate date]; _hijriCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSIslamicCalendar

I'm handling UIApplicationSignificantTimeChangeNotification in my app and all the other screens in the app are gracefully refreshed when midnight comes. The one I have trouble with is with UIDatePicker . UIPickerView has refreshAllComponents method which I use in another screen to make an update on midnight change. I would like to have the same for UIDatePicker , but unfortunately I couldn't find a way to refresh it, and Today remains Today , although it is already Yesterday . Any way out? Why not replace the UIDatePicker with new instance? UIDatePicker *oldPicker = self.myDatePicker;

I have an app where I ask for the users birthday with a UIDatePicker then store it in standard user defaults. When the app is opened again I get the date again and then want to set the UIDatePicker to that date but it's crashing and not accepting the date. It's being stored in the format "June 8, 2009." How do I need to do this? This is the way I'm trying it now: - (void)viewWillAppear:(BOOL)animated { birthDate = [Preferences getBirthDate]; if (birthDate == nil) { [datePicker setDate:[NSDate date] animated:NO]; } } My user pref methods look like this in their class: + (NSDate *)getBirthDate {
