UIDatePicker in UIPopover
Now since you have tagged iPhone It can clearly be assumed that you are trying to use UIPopoverController
in iPhone
But UIPopoverController
is available only for iPad
. So it is resulting in a crash since iPhone doesn't recognize that controller.
Try with below code. It will work fine:
Objective-C
- (IBAction)showDatePicker:(UIButton *)sender {
UIDatePicker *datePicker = [[UIDatePicker alloc]init];//Date picker
datePicker.frame = CGRectMake(0, 0, 320, 216);
datePicker.datePickerMode = UIDatePickerModeDateAndTime;
[datePicker setMinuteInterval:5];
[datePicker addTarget:self action:@selector(dateChanged:) forControlEvents:UIControlEventValueChanged];//need to implement this method in same class
UIView *popoverView = [[UIView alloc] init]; //view
popoverView.backgroundColor = [UIColor clearColor];
[popoverView addSubview:datePicker];
// here you can add tool bar with done and cancel buttons if required
UIViewController *popoverViewController = [[UIViewController alloc] init];
popoverViewController.view = datePicker;
popoverViewController.view.frame = CGRectMake(0, 0, 320, 216);
popoverViewController.modalPresentationStyle = UIModalPresentationPopover;
popoverViewController.preferredContentSize = CGSizeMake(320, 216);
popoverViewController.popoverPresentationController.sourceView = sender; // source button
popoverViewController.popoverPresentationController.sourceRect = sender.bounds; // source button bounds
//popoverViewController.popoverPresentationController.delegate = self;
[self presentViewController:popoverViewController animated:YES completion:nil];
}
- (void)dateChanged:(UIDatePicker *)datePicker {
NSLog(@"DATE :: %@", datePicker.date);
}
Swift 4.2
@IBAction func showDatePicker(_ sender: UIButton) {
let datePicker = UIDatePicker()//Date picker
let datePickerSize = CGSize(width: 320, height: 216) //Date picker size
datePicker.frame = CGRect(x: 0, y: 0, width: datePickerSize.width, height: datePickerSize.height)
datePicker.datePickerMode = .dateAndTime
datePicker.minuteInterval = 5
datePicker.addTarget(self, action: #selector(dateChanged(_:)), for: .valueChanged)
let popoverView = UIView()
popoverView.backgroundColor = UIColor.clear
popoverView.addSubview(datePicker)
// here you can add tool bar with done and cancel buttons if required
let popoverViewController = UIViewController()
popoverViewController.view = popoverView
popoverViewController.view.frame = CGRect(x: 0, y: 0, width: datePickerSize.width, height: datePickerSize.height)
popoverViewController.modalPresentationStyle = .popover
popoverViewController.preferredContentSize = datePickerSize
popoverViewController.popoverPresentationController?.sourceView = sender // source button
popoverViewController.popoverPresentationController?.sourceRect = sender.bounds // source button bounds
popoverViewController.popoverPresentationController?.delegate = self // to handle popover delegate methods
self.present(popoverViewController, animated: true, completion: nil)
}
@objc func dateChanged(_ datePicker: UIDatePicker) {
print("DATE :: \(datePicker.date)")
}
Same code will work iPhone also if you implement below delegate respective in view controller
extension YourViewController : UIPopoverPresentationControllerDelegate {
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
// Force popover style
return UIModalPresentationStyle.none
}
}
