iOS8UIPickerViewでの表示UIActionSheetが機能しない
コードは iOS7 で動作しますが、iOS8では動作しません。UIActionSheet が iOS8 で廃止され、Apple が使用を推奨しているためだと確信していますUIAlertController。
しかし、iOS8でそれを行う方法は? 私は使用する必要がありますUIAlertControllerか？

UIActionSheet のリファレンスから:
UIActionSheet はサブクラス化するようには設計されていないため、その階層にビューを追加するべきではありません。UIActionSheet API で提供される以上のカスタマイズでシートを表示する必要がある場合は、独自のシートを作成して、presentViewController:animated:completion: でモーダルに表示できます。
私の推測では、あなたはその理由を正確に理解していると思います。
UIAlertController のリファレンスには同様の免責事項はありませんが、そのインターフェイスを見ると、Apple はリリース前にそれを追加すると思います。
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をお勧めします。それほど難しいことではなく、意図した用途を超えてインターフェイスをプッシュしないでください。

iOS8 の UIActionSheet ではなく、自分でタイム ピッカーを作成します。

UIActionSheet は iOS8 で廃止されました。iOS8以降のUIAlertControllerを使用する
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];

このアクション シート シミュレーションを使用してみてください。

UIScreen.mainScreen.bounds.size.height)];
[simulatedActionSheetView setBackgroundColor:[UIColor clearColor]];
CGFloat pickerViewYpositionHidden = UIScreen.mainScreen.bounds.size.height + pickerToolbar.frame.size.height;
CGFloat pickerViewYposition = UIScreen.mainScreen.bounds.size.height -
pickerView.frame.size.height +
UIApplication.sharedApplication.statusBarFrame.size.height;
[pickerView setFrame:CGRectMake(pickerView.frame.origin.x,

pickerView.frame.size.height)];
[pickerToolbar setFrame:CGRectMake(pickerToolbar.frame.origin.x,

私は同じ問題に直面し、この方法で解決しました。すべてのiOSバージョンで動作します
iOS 8 では、Apple は非常に多くのことを変更しました。ここでは、自分のプロジェクトで 1 つの問題に直面したので、代わりにソリューションを提供したいと思いUIActionsheetます。
iOS 8 ではUIActionsheet非推奨になり、そのデリゲート メソッドも非推奨になりました。その代わりに、UIAlertControllerpreferredstyle
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 とそれ以前のバージョンの両方で機能します。
.h ファイルでこの変数を宣言します
@interface demoProfileForBuyer{
UIActionSheet *ac_sheet_fordate;
UIToolbar *pickerToolBar_fordate;
UIDatePicker *optionPickerDate;
UIAlertController *alertController;
}
.m ファイルで

UIActionSheet を使用した UIPickerView が iOS 8 で機能しないことを示す同じ問題があります。UIActionSheet は廃止され、Apple は UIAlertController の使用を推奨しているためです。だから私たちは巻き上げる必要があります。
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。お役に立てば幸いです。
#define CONTENT_HEIGHT 478
- (void)initSheetWithWidth:(CGFloat)aWidth
{
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
UIAlertController *sheet = [UIAlertController alertControllerWithTitle:@"hack space" message:@"\n\n\n\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];
[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)],
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerSheetDone)]
]];
UIDatePicker *picker = [[UIDatePicker alloc]
initWithFrame:CGRectMake(0, toolbar.bounds.size.height, aWidth, 0)];
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
UIAlertController *sheet = self.sheet;
[view addSubview:toolbar];
[view addSubview:picker];
[sheet.view addSubview:view];
} else {
UIActionSheet *sheet = self.sheet;
[sheet addSubview:toolbar];
[sheet addSubview:picker];
}
self.picker = picker;
}
- (void)showWithDate:(NSDate*)date {
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
// Reload and select first item
[self.picker setDate:date];
[self.parentViewController presentViewController:self.sheet animated:YES completion:nil];
} else {
UIActionSheet *sheet = self.sheet;
[self.sheet showInView:self.containerView];
// XXX: Kinda hacky, but seems to be the only way to make it display correctly.
[self.sheet
setBounds:CGRectMake(0, 0,
self.containerView.frame.size.width,
sheet.frame.size.height - CONTENT_HEIGHT)];
// Reload and select first item
[self.picker setDate:date];
[UIView animateWithDuration:0.25 animations:^{
[self.sheet
setBounds:CGRectMake(0, 0,
self.containerView.frame.size.width,
sheet.frame.size.height)];
}];
}
}
この問題を解決することがすべてだと思います。ハッピーコーディング！

これを試して。
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:@"\n\n\n\n\n\n\n\n\n\n\n"
preferredStyle:UIAlertControllerStyleActionSheet];
__weak typeof(self) weakSelf = self;
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
[weakSelf pickActionSheetFinishAction];
}];
[alertController addAction:cancelAction];
[alertController.view addSubview:self.topicPickView];
[self presentViewController:alertController animated:YES completion:nil];
