I have a UIDatePicker with a minimumDate and maximumDate set. The default UI of the date picker shows all dates, including those before the minimum and after the maximum. If the user spins to an out-of-bounds date, the picker does spin back - but this is not a great user experience. Can I make it so that the picker simply doesn't display out-of-bounds dates?
In my case, this is particularly important because my app deals with historic events. The date picker starts at the current date and allows users to spin back in time. It's faintly ridiculous in this situation to show tomorrow's date below the current date.

The default behavior of FSCalendar is that if a month is currently being displayed (for example December) and the user taps to select a day from the previous month (November), the calendar will scroll to the previous month.
Is there a way to prevent that automatic scrolling, without disabling selection?
I have a date picker that is set to not allow users to pick future dates. It's maximum date is set for the current time on viewDidLoad.
dateDatePicker.maximumDate = NSDate()
But I've been noticing a bug. Today until midday the maximum date was yesterdays date. But now, after midday it is showing todays date.
The way I implemented it: The date picker is shown and hidden with alpha when user wants to use it. So I am setting the maximum date not every time the picker is shown but once it loads the view it is in.
So I am not sure if this is a bug?
Is it has to do with timezones?
Or has to do with the fact that I am only calling dateDatePicker.maximumDate once when they view loaded and that could have happened days ago?
Or if I should reset the maximumDate every time I show the datePicker?
Yes, you should almost certainly set the maximum date each time you show the date picker.
If you set the maximum date on a previous day and then never updated it nor closed the view controller the it wouldn't change.
Set it in viewWillAppear, not viewDidLoad.
If that doesn't work, use NSCalendar and NSDateComponents to build an NSDate which is 23:59 on the current date (fetch the MM/DD/YYYY from the current date as date components, then manually set the time to 23:59. That should work.
Is it possible to set in UIDatePicker, date/time frames selectively? for example: show only Mondays from 8am to 4pm ?
Unfortunately, you cannot do this with standard UIDatePicker. Instead you should build your own custom date picker based on UIPickerView.
I want to display dates in UIImagePicker within a range, I have start date and I will select start date and end date should automatically appear for a week, dates from past one week should appear. i.e if start date is 10 and end date should be displayed as 3 and dates should be Populated between 10 to 3 which should be displayed in iOS.
just use the maximumDate and minimumDate properties of UIDatePicker
is there any way in excel that would allow me to pick a specific time in a format HH:MM. The
Date and Time picker allows to select only Calendar Day.
Desired result would be something like
Rad Time Picker
with a 1 minute sequence
You could set up 2 cells (one for hour, one for minutes), and set up corresponding spin buttons and have each cycle through the hours and minutes as you desire. then a button to grab the result and place it where you want.
