iOS8でUIActionSheetを使用してUIPickerViewを表示しない
iOS8のUIPickerViewでUIActionSheetを表示しない
コードはiOS7で動作しますが、iOS8では動作しません。 UIActionSheetがiOS8およびApple推奨されるUIAlertController 。
しかし、iOS8でそれを行う方法は？ UIAlertControllerを使用する必要がありますか？

UIActionSheetのリファレンスから：
UIActionSheetはサブクラス化するように設計されていません。また、階層にビューを追加する必要もありません。 UIActionSheet APIによって提供されるよりも多くのカスタマイズを使用してシートを表示する必要がある場合、独自のシートを作成し、presentViewController：animated：completion：でモーダルに表示できます。
私の推測は、あなたが正確にその理由を見ていることです。
UIAlertControllerのリファレンスには同様の免責事項はありませんが、インターフェイスを見ると、Appleはリリース前に追加されます。
私の推奨事項は、ピッカーとボタンを含む小さなビューを作成し、必要に応じて表示および非表示にすることです。それはそれほど難しくなく、意図した用途を超えてインターフェースをプッシュしません。
同じ視覚効果を達成するには、ActionSheetPicker-3.を使用できます。これは iOS 8。
実際、もうUIActionSheetではありません。しかし、まったく同じように見えるため、iOS 8で動作します。
UIActionSheetはiOS8で廃止されました。 UIAlertControllerforiOS8以降
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
message:@"This is an action shhet."
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* cameraAction = [UIAlertAction actionWithTitle:@"Take A Photo" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
UIAlertAction* galleryAction = [UIAlertAction actionWithTitle:@"From Gallery" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
UIAlertAction * defaultAct = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {}];
[alert addAction:cameraAction];
[alert addAction:galleryAction];
[alert addAction:defaultAct];
[self presentViewController:alert animated:YES completion:nil];

IOS8ではUIActionSheetの代わりに自分でタイムピッカーを記述します。

私は同じ問題に直面し、すべてのiOSバージョンで動作するようにこの方法で解決しました
IOS 8では、Appleは私がここで自分のプロジェクトで1つの問題に直面した多くのことを変更したので、UIActionsheetの代わりに解決策を提供したいだけです。
ios 8 UIActionsheetでは非推奨になり、デリゲートメソッドも非推奨になりました。代わりにUIAlertControllerをprefferedstyleでUIAlertControllerStyleActionSheetが使用されます。このスレッドも確認できます：
https://developer.Apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html
この例は、iOS 8と以前のバージョンの両方で機能します。

UIActionSheetが廃止され、AppleはUIAlertControllerを使用することを推奨しています。
私は私のケースを解決するためにいくつかのコードを書きました。それがあなたのお役に立てば幸いです。

[sheet.view setBounds:CGRectMake(7, 0, aWidth, CONTENT_HEIGHT)]; // Kinda hacky
self.sheet = sheet;
} else {
UIActionSheet *sheet = [[UIActionSheet alloc] init];
self.sheet = sheet;
}
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, aWidth, CONTENT_HEIGHT)];
[view setBackgroundColor:[UIColor whiteColor]];
UIToolbar *toolbar = [[UIToolbar alloc]
initWithFrame:CGRectMake(0, 0, aWidth, 0)];
toolbar.barStyle = UIBarStyleDefault;
[toolbar sizeToFit];
[toolbar setItems:@[
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(pickerSheetCancel)],

この問題を修正するのはすべてだと思います。ハッピーコーディング！
Swift 5
これを行うには、UIAlertControllerを使用できます。
@IBAction func btnActionDate(_ sender: Any) {
let picker = UIPickerView(frame: CGRect(x: 0, y: 50, width: self.view.frame.size.width - 16.0, height: 150))
picker.delegate = self
picker.dataSource = self
// let message = "\n\n\n\n\n\n"
let alert = UIAlertController(title: "Title of Action Sheet", message: "", preferredStyle: UIAlertController.Style.actionSheet)
alert.isModalInPopover = true
picker.reloadAllComponents()
//Add the picker to the alert controller
alert.view.addSubview(picker)
// For setting height of Action sheet
let height:NSLayoutConstraint = NSLayoutConstraint(item: alert.view!, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 350)
alert.view.addConstraint(height)
let okAction = UIAlertAction(title: "Done", style: .default, handler: {
(alert: UIAlertAction!) -> Void in
let fetchedObj = picker.selectedRow(inComponent: 0)
})
alert.addAction(okAction)
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
alert.addAction(cancelAction)
self.present(alert, animated: true, completion: nil)
}
このようにpickerViewのデリゲートとデータソースを設定します
class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource
デリゲートとデータソース関数を設定します
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return arrayMonthData.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return arrayMonthData[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
}
func pickerView(_ pickerView: UIPickerView, widthForComponent component: Int) -> CGFloat {
return self.view.frame.size.width - 16.0
}
func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat {
return 36.0
}
私のコードを見てください
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:@"\n\n\n\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];
