Показването на UIPickerView с UIActionSheet в iOS8 не работи

От справката за UIActionSheet:

UIActionSheet не е проектиран да бъде подклас, нито трябва да добавяте изгледи към неговата йерархия. Ако трябва да представите лист с повече персонализиране от предоставеното от UIActionSheet API, можете да създадете свой собствен и да го представите модално с presentViewController:animated:completion:.

Предполагам, че виждате точно защо.

Справката за UIAlertController няма подобен отказ от отговорност, но гледайки интерфейса, предполагам, че Apple ще го добави преди пускането.

Моята препоръка е просто да създадете малък изглед, съдържащ вашия инструмент за избор и бутони и да го показвате и скривате, ако е необходимо. Не е толкова трудно да се направи и не избутвате интерфейсите извън предназначението им.

Пиша инструмента за избор на време от себе си вместо UIActionSheet в iOS8:

date = [NSDate date];

timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];
timePicker.datePickerMode = UIDatePickerModeDateAndTime;
timePicker.hidden = NO;
timePicker.date = date;

displayFormatter = [[NSDateFormatter alloc] init];
[displayFormatter setTimeZone:[NSTimeZone localTimeZone]];
[displayFormatter setDateFormat:@"MM月dd日 EEE HH:mm"];

formatter = [[NSDateFormatter alloc] init];
[formatter setTimeZone:[NSTimeZone localTimeZone]];
[formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];

startDisplayTimeString = [displayFormatter stringFromDate:timePicker.date];
startTimeString = [formatter stringFromDate:timePicker.date];

NSTimeInterval interval = 24*60*60*1;
NSDate *endDate = [[NSDate alloc] initWithTimeIntervalSinceNow:interval];
endDisplayTimeString = [displayFormatter stringFromDate:endDate];
endTimeString = [formatter stringFromDate:endDate];

[_startTimeLabel setText:startDisplayTimeString];
[_endTimeLabel setText:endDisplayTimeString];

[pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];

NSDateFormatter *dateFormatter =[[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
pickerToolbar.tintColor = [UIColor whiteColor];
[pickerToolbar sizeToFit];

                                   nil] forState:UIControlStateNormal];

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

UIBarButtonItem *titleButton;

float pickerMarginHeight = 168;

                                     nil] forState:UIControlStateNormal];

UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:@"OK" style:UIBarButtonItemStyleDone target:self action:@selector(setTimePicker)];

[doneBtn setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                 [UIColor colorWithRed:253.0/255.0 green:68.0/255.0 blue:142.0/255.0 alpha:1.0],

                                 nil] forState:UIControlStateNormal];

NSArray *itemArray = [[NSArray alloc] initWithObjects:cancelBtn, flexSpace, titleButton, flexSpace, doneBtn, nil];

[pickerToolbar setItems:itemArray animated:YES];

if(iPad){

    [pickerToolbar setFrame:CGRectMake(0, 0, 320, 44)];

    UIViewController* popoverContent = [[UIViewController alloc] init];
    popoverContent.preferredContentSize = CGSizeMake(320, 216);
    UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 216)];
    popoverView.backgroundColor = [UIColor whiteColor];
    [popoverView addSubview:timePicker];
    [popoverView addSubview:pickerToolbar];
    popoverContent.view = popoverView;

    [timeBackgroundView addSubview:pickerToolbar];
    [timeBackgroundView addSubview:timePicker];

    [self.view addSubview:timeBackgroundView];}

UIActionSheet е оттеглен в iOS8. Използвайте UIAlertController за iOS8 или по-нова версия

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];

Реф.: UIAlertController

Пример: https://github.com/KiritVaghela/UIAlertController

Сблъсквал съм се със същия проблем и го реших по този начин, че ще работи във всички версии на iOS

В iOS 8 Apple промени толкова много неща, че се сблъсках с един проблем в собствения си проект, така че просто искам да предложа решението в замяна на UIActionsheet.

в ios 8 UIActionsheet отхвърлен, както и неговите делегирани методи също са отхвърлени. Вместо това се използва UIAlertController с предпочитан стил
UIAlertControllerStyleActionSheet. можете да проверите и тази тема:

https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html

Този пример ще работи както в ios 8, така и в предишната му версия.

Благодаря.

Имам същия проблем с вас, показването на UIPickerView с UIActionSheet не работи в iOS 8. Тъй като UIActionSheet е остарял и Apple препоръчва да се използва UIAlertController. Така че трябва да закръглим, за да навием.

Написах код за разрешаване на моя случай. Надявам се, че може да ви помогне.

#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)];
        }];
    }
}

Мисля, че всичко е, за да се реши този проблем. Приятно кодиране!

Swift 5

Можете да използвате UIAlertController, за да направите това.

@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)
    }

Задайте делегатите и източника на данни на pickerView по този начин

class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource

задайте функциите за делегат и източник на данни

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
    }

Опитайте тази.

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
                                                               message:@"\n\n\n\n\n\n\n\n\n\n\n"
