How to add UIDatePicker in UIAlertController in iOS8?
Solution 1
Adding UIDatePicker to action sheet was discouraged by Apple all along. Since iOS 7, Apple had introduced the use of inline date picker (see how it is done in the Calendar app).
If you managed to hack a workaround using UIAlertController, it may probably break again in future iOS releases.
Solution 2
For iOS9+ Swift code here.
add target to your date button or other view.
dateBtn.addTarget(self,action: #selector(YourViewController.dateSelect(_:)),forControlEvents: UIControlEvents.TouchDown) //my date button
func dateSelect(sender:UIButton) {
if (UI_USER_INTERFACE_IDIOM() == .Phone)
{
//init date picker
self.datePicker = UIDatePicker(frame: CGRectMake(0, 0, self.view.frame.size.width,260))
self.datePicker.datePickerMode = UIDatePickerMode.Date
//add target
self.datePicker.addTarget(self, action: #selector(YourViewController.dateSelected(_:)), forControlEvents: UIControlEvents.ValueChanged)
//add to actionsheetview
if(UIDevice.currentDevice().systemVersion >= "8.0")
{
let alertController = UIAlertController(title: "Date Selection", message:" " , preferredStyle: UIAlertControllerStyle.ActionSheet)
alertController.view.addSubview(self.datePicker)//add subview
let cancelAction = UIAlertAction(title: "Done", style: .Cancel) { (action) in
self.dateSelected(self.datePicker)
self.tableView.reloadData()
}
//add button to action sheet
alertController.addAction(cancelAction)
let height:NSLayoutConstraint = NSLayoutConstraint(item: alertController.view, attribute: NSLayoutAttribute.Height, relatedBy: NSLayoutRelation.Equal, toItem: nil, attribute: NSLayoutAttribute.NotAnAttribute, multiplier: 1, constant: 300)
alertController.view.addConstraint(height);
self.presentViewController(alertController, animated: true, completion: nil)
}
}
}
//selected date func
func dateSelected(datePicker:UIDatePicker)
{
let dateFormatter = NSDateFormatter()
dateFormatter.dateStyle = NSDateFormatterStyle.ShortStyle
let currentDate = datePicker.date
let day = currentDate.day()
let month = currentDate.month()
let year = currentDate.year()
let date = "\(day)/\(month)/\(year)"
print(date)
}
Solution 3
this works for me
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"\n\n\n\n\n\n\n\n\n\n\n" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIDatePicker *picker = [[UIDatePicker alloc] init];
[picker setDatePickerMode:UIDatePickerModeDate];
[alertController.view addSubview:picker];
[alertController addAction:({
UIAlertAction *action = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
NSLog(@"OK");
NSLog(@"%@",picker.date);
}];
action;
})];
UIPopoverPresentationController *popoverController = alertController.popoverPresentationController;
popoverController.sourceView = sender;
popoverController.sourceRect = [sender bounds];
[self presentViewController:alertController animated:YES completion:nil];

A clean way to do it in Swift 2:
let vc = UIAlertController(title: "Pickup time", message: nil, preferredStyle: .Alert)
vc.addTextFieldWithConfigurationHandler({ (textfield) -> Void in
let datepicker = UIDatePicker()
// add delegate ... here
textfield.inputView = datepicker
})
vc.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
vc.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
presentViewController(vc, animated: true, completion: nil)
Solution 5
@idris code in swift3
//Function Start
func dateSelect() {
//init date picker
let datePicker = UIDatePicker(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 260))
datePicker.datePickerMode = UIDatePickerMode.date
//add target
datePicker.addTarget(self, action: #selector(dateSelected(datePicker:)), for: UIControlEvents.valueChanged)
//add to actionsheetview
let alertController = UIAlertController(title: "Date Selection", message:" " , preferredStyle: UIAlertControllerStyle.actionSheet)
alertController.view.addSubview(datePicker)//add subview
let cancelAction = UIAlertAction(title: "Done", style: .cancel) { (action) in
self.dateSelected(datePicker: datePicker)
}
//add button to action sheet
alertController.addAction(cancelAction)
let height:NSLayoutConstraint = NSLayoutConstraint(item: alertController.view, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1, constant: 300)
alertController.view.addConstraint(height);
self.present(alertController, animated: true, completion: nil)
}
//selected date func
@objc func dateSelected(datePicker:UIDatePicker) {
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = DateFormatter.Style.short
let currentDate = datePicker.date
print(currentDate)
}

I am working on a project which I had already released with iOS-7. But now as the action sheet is making problem so I am now implementing UIAlertController. Following is the code which I am using for showing UIAlertController with UIPicker.
alertController = [UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleActionSheet]; UIAlertAction *alertAction = [UIAlertAction actionWithTitle:@"" style:UIAlertActionStyleDefault handler:nil]; [alertController addAction:alertAction]; [alertController addAction:alertAction]; [alertController addAction:alertAction]; [alertController addAction:alertAction]; [pickerToolbar setFrame:CGRectMake(0, 0, self.view.frame.size.width-20, 44)]; [alertController.view addSubview:pickerToolbar]; [alertController.view addSubview:picker]; [alertController.view setBounds:CGRectMake(0, 0, self.view.frame.size.width, 485)]; [self presentViewController:alertController animated:YES completion:nil];
But I am not able to add datepicker in it. It is not working same as normal picker and the app hang. Please advice for any sample code for adding UIDatePicker in UIAlertController. Thanks in advance
