24h UIDatePicker does not offer 24 hours in certain circumstances - ios

In my app, users can pick a "duration". I am using a UIDatePicker with datePickerMode set to time for this.
In order to pick 0-24h, I set the date picker locale to e.g. NL like explained here.
Because I want to show the picker in a list, I use compact for the preferredDatePickerStyle
In order to make it easier for the user to pick a duration, I set minuteInterval to 5
Now, when using this on a device that has 12h time display in the iOS settings, this causes the expanded date picker to only offer hours from 1-12, instead of 0-23.
Interestingly, this problem does not occur when the device is set to 24h time display or I am using any other value for the minuteInterval (e.g. 10) or I am using a different preferredDatePickerStyle (e.g. inline)
Is this an iOS bug and is there any workaround?

Have you tried to change the Mode from Attributes Inspector ? By default the mode is set to Date and Time. You need to change it from there or you can create your own CustomDatePicker to display only the months or only the years.
Take a look to this CustomDatePicker example here:
https://github.com/Anandsan/UICustomDatePicker
Or you can use a UIPickerView to set all the months and another UIPickerView to set the years you want to display and after that you can extract the selected values and to use them in your app.

UIDatepicker display future years with ' ---'

iOS UIDatepicker shows '---' for future years. How to achive this in iOS. It will show only till current year and after that it shows '---'. I seen this when we adding any contact in our iPhone contact app, where there is field to addBirth. You can see that.
Please see screen shot.
The UIDatePicker doesn't have option for this.
Available Picker modes: time, date, dateAndTime, countDownTimer.
You can set maximumDate value, so that date after that can't be selected using UIDatePicker.
If you need to fulfil the exact need, you have to create custom UIPickerView with multiple component and Manage all things. NB: This could be messy.

How to DatePicker with Year Month day time

How to get DatePicker |Year|Day Date Month|Time Min|Second|AM PM| ?
Default DatePicker Showing its showing |Day Date Month | Min | Seconds|
Date picker is a very high level component and does not allow explicit setting of display in any way. There are properties you can play around with such as datePickerMode and locale. For your case I guess you should find a correct locale.
This is not advised though. The thing is that locale is set automatically or it should be set to whatever makes sense to user which world-wide depends on the user. If you override this functionality you will most likely confuse users.
Anyway if you can't get the result you want with date picker you will have to user a normal picker view and manage sections and rows yourself.
You can get some how close to your desired requirement by setting DatePicker's datePickerMode property
myDatePicker.datePickerMode = .dateAndTime
see the more available datepicker mode .here
UIDatePicker takes device Time format. If you have 24 hour Date format selected in your device, the UIDatePicker will not show AM/PM and show the time in 24hr. format. So you have to change the Time format of the device to 12 hour format. We can not set the time format of the UIDatePicker.

Changing locale of UIDatePicker in Countdown Timer mode

I have UIDatePicker in CountdownTimer mode and need to change the wording of hours and min to German locale. I tried both, to set locale to German (Germany) in storyboard and in code, but both failed and the app still shows default english words for hours and min.
timePicker.locale = Locale(identifier: "de")
When I configure locale on UIDatePicker in Date and Time mode, it correctly respects German locale and displays the date in german format. Any idea why locale does not change in Countdown timer mode? Thank you.
Thanks to Why UIActivityViewController doesn't display localized cancel string? post the solution also resolved the issue of localizing UIDatePicker in countdown timer mode, at least on iOS 11. Thank you.
Add this row into your info.plist:

I am mentioning here reply from APPLE that i got upon Technical support on this specific issue but unfortunately there is no support to this feature yet.
When running in the count down mode, UIDatePicker showns the hours and minutes to count down. In this context, the “hours” and “minutes” are not a format, thus not covered by locale;
Thing is that they did not mention any time line for support of this feature.

UIDatePicker in countdown mode: Can I have a countdown thats longer than 23:59?

I want the user to be able to elegantly enter an NSTimeInterval, and UIDatePicker's UIDatePickerModeCountDownTimer picker mode seems perfect for that.
However, in countdown mode the date picker only allows a maximum value of 23 hours and 59 minutes – it's not possible to enter anything longer than that by default.
Is there a way I can make the date picker's interval greater than 24 hours? If not, what other ways are there – maybe a custom UIPickerView?
Guess I have to create my own subclass of UIPicker then.
