<p>My application has a need to let the user choose a date from a list of dates conforming to a certain pattern. For instance, they may need to choose a monday from a list Monday's for a month. Is there a way to get a <code>UIDatePicker</code> to limit date choices to a certain subset or should I just use a <code>UIPickerView</code>?</p>

You cannot limit which dates are selectable in a
```
UIDatePicker
```
. You could change the date when the value changed event is sent, but since the user cannot tell which dates are "good" and which are not, it's a bad UI choice to do so.
Use a
```
UIPickerView
```
of your own making instead.
