I want my iPhone app to have a date&time picker with constraints on time 10 AM to 5 PM for all future days. For example,my user should be able to select today with maximum of 5 PM or a future date with time between 10 am and 5 pm.
The minimum and maximum date properties doesnt help me with my requirement. Any possible solution? Thanks in advance :)
UIDatePicker doesn't appear to support a minimum or maximum time, only date.
You will have to either subclass UIDatePicker and create your own, or possibly alert the user when they select something out of your bounds.

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?
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 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.
I am developing an iPhone app where user can save Birthdays along with other data.
For Birthday I am trying to add a UIDatePicker that shows date, month and year. for the year I want to set the picker maximum range to current year and after that an empty slot (just like the contact/phone app - add birthday option).
Is there anyway I can do that using UIDatePicker or do I have to use custom picker.
You can set the property maximumDate with current Date object. It will not allow the user to select any date beyond today. However it will not show the empty slots but grayed out slots. If user will try to select it, picker will again set with max possible date.
datePicker. maximumDate = [NSDate date];
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.
