[theDatePicker release];
[dtpicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged];

pickerDateToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];

Marcio's excellent solution to this question was of great help to me in adding subviews of any kind to a UIActionSheet.

For reasons that are not (yet) entirely clear to me, the bounds of the UIActionSheet can only be set after it has been displayed; both sagar's and marcio's solutions successfully address this with a setBounds:CGRectMake(...) message being sent to the actionsheet after it is shown.

However, setting the UIActionSheet bounds after the sheet has been displayed creates a jumpy transition when the ActionSheet appeaars, where it "pops" into view, and then only scrolls in over the final 40 pixels or so.

When sizing a UIPickerView after adding subviews, I recommend wrapping the setBounds message sent to the actionSheet inside an animation block. This will make the entrance of the actionSheet appear smoother.

<pre><code>UIActionSheet *actionSheet = [[[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];


// add one or more subviews to the UIActionSheet
// this could be a UIPickerView, or UISegmentedControl buttons, or any other 
// UIView. Here, let's just assume it's already set up and is called 
// (UIView *)mySubView
[actionSheet addSubview:myView];

// show the actionSheet
[actionSheet showInView:[UIApplication mainWindow]];


// Size the actionSheet with smooth animation
 [UIView beginAnimations:nil context:nil];
 [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
 [UIView commitAnimations]; 
</code></pre>

I don't really understand why the <code>UIPickerView</code> is going inside a <code>UIActionSheet</code>. This seems to be a messy and hacky solution, which can be broken in a future iOS release. (I've had things like this break in an app before, where the <code>UIPickerView</code> wasn't being presented on the first tap and had to be retapped - weird quirks with the <code>UIActionSheet</code>).

What I did is simply implement a <code>UIPickerView</code> and then added it as a subview to my view, and animate it moving up as though it were being presented like an action sheet.

<pre><code>/// Add the PickerView as a private variable

Update for iOS 7

<a href="https://developer.apple.com/library/ios/documentation/uikit/reference/UIActionSheet_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40006801-CH3-DontLinkElementID_2" rel="nofollow noreferrer">Apple docs for UIActionSheet</a>: <code>UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy</code>

I recommend against trying to customize the contents of an ActionSheet, as it can lead to serious invalid context errors in iOS 7. I just spent a few hours working through this problem and ultimately decided to take a different approach. I replaced the call to show the action sheet with a modal view controller containing a simple tableview. 

There are many ways to accomplish this. Here's one way that I just implemented in a current project. It's nice because I can reuse it between 5 or 6 different screens where I all users to select from a list of options.

<ol>
<li>Create a new UITableViewController subclass, <code>SimpleTableViewController</code>.</li>
<li>Create a UITableViewController in your storyboard (embedded in a navigation controller) and set its custom class to SimpleTableViewController.</li>
<li>Give the navigation controller for SimpleTableViewController a Storyboard ID of "SimpleTableVC". </li>
<li>In SimpleTableViewController.h, create an NSArray property that will represent the data in the table.</li>
<li>Also in SimpleTableViewController.h, create a protocol <code>SimpleTableViewControllerDelegate</code> with a required method <code>itemSelectedatRow:</code>, and a weak property called delegate of type <code>id&lt;SimpleTableViewControllerDelegate&gt;</code>. This is how we will pass the selection back to the parent controller.</li>
<li>In SimpleTableViewController.m, implement the tableview data source and delegate methods, calling <code>itemSelectedatRow:</code> in <code>tableView:didSelectRowAtIndexPath:</code>.</li>
</ol>

This approach has the added benefit of being fairly reusable. To use, import the SimpleTableViewController class in your ViewController.h, conform to the SimpleTableViewDelegate, and implement the <code>itemSelectedAtRow:</code> method. Then, to open the modal just instantiate a new SimpleTableViewController, set the table data and delegate, and present it.

<pre><code>UINavigationController *navigationController = (UINavigationController *)[self.storyboard instantiateViewControllerWithIdentifier:@"SimpleTableVC"];
SimpleTableViewController *tableViewController = (SimpleTableViewController *)[[navigationController viewControllers] objectAtIndex:0];
tableViewController.tableData = self.statesArray;
tableViewController.navigationItem.title = @"States";
tableViewController.delegate = self;
[self presentViewController:navigationController animated:YES completion:nil];
</code></pre>

I create a simple example and <a href="https://github.com/kmc239/KMCModalTableView" rel="nofollow noreferrer">posted it on github</a>.

I liked the approach taken by Wayfarer and flexaddicted, but found (like aZtral) that it did not work as the backgroundTapButton was the only element that was responding to user interaction. This led me to put all three of his subviews: _picker, _pickerToolbar and backgroundTapButton inside a containing view (popup) which was then animated on and off the screen. I also needed a Cancel button on the _pickerToolbar. Here are the relevant code elements for the popup view (you need to supply your own picker data source and delegate methods).

 _popup.center = CGPointMake(rect.size.width / 2.0, rect.size.height + _popup.frame.size.height / 2.0);
 [_popup addSubview:_picker];
 [_popup insertSubview:_pickerToolbar aboveSubview:_picker];

 // Animate it moving up
 // This seems to work though I am not sure why I need to take off the topNavHeight
 CGFloat vertCentre = (_popup.frame.size.height - topNavHeight) / 2.0;

 [UIView animateWithDuration:DURATION animations:^{
 // move it to a new point in the middle of the screen
 [_popup setCenter:CGPointMake(rect.size.width / 2.0, vertCentre)];
 } completion:^(BOOL finished) {
 // When done, place an invisible 'button' on the view behind the picker,
 // so if the user "taps to dismiss" the picker, it will go away
 self.backgroundTapButton = [UIButton buttonWithType:UIButtonTypeCustom];

 [_backgroundTapButton addTarget:self action:@selector(doneAction:) forControlEvents:UIControlEventTouchUpInside];

Since iOS 8, you can't, it doesn't work because Apple changed internal implementation of <code>UIActionSheet</code>. Please refer to <a href="https://developer.apple.com/library/ios/documentation/uikit/reference/uiactionsheet_class/Reference/Reference.html" rel="nofollow">Apple Documentation</a>:

<blockquote>
 Subclassing Notes
 
 UIActionSheet is not designed to be subclassed, nor
 should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.
</blockquote>

My application requires following things to be added in an action sheet.

<ul>
<li>UIToolbar</li>
<li>Button on UIToolbar</li>
<li>UIPicker Control</li>
</ul>

I have included an image to understand my requirements.
