在iOS8中显示带有UIActionSheet的UIPickerView无法正常工作

iOS8 中显示UIPickerView UIActionSheet无效

代码适用于 iOS7 ,但它无法在 iOS8 中使用。我确定这是因为UIActionSheet在 iOS8 中已弃用,Apple建议使用UIAlertController

但是,如何在 iOS8 中执行此操作?我应该使用UIAlertController

来自UIActionSheet的参考资料:

  

UIActionSheet不是为子类设计的,也不应该在其层次结构中添加视图。如果您需要提供比UIActionSheet API提供的更多自定义的工作表,您可以创建自己的工作表并使用presentViewController以模态方式呈现它:animated:completion:。

我的猜测是你确切看到了原因。

UIAlertController的参考资料没有类似的免责声明,但是看看它的界面,我的猜测是Apple会在发布之前添加它。

我的建议是创建一个包含选择器和按钮的小视图,并根据需要显示和隐藏它。这并不难做到,而且你没有超越其预期用途推动界面。

答案 1 :(得分:6)

要获得相同的视觉效果,您可以使用 ActionSheetPicker-3.0 iOS 8

实际上,它不再是UIActionSheet了。但看起来完全相同,这就是为什么它适用于 iOS 8

答案 2 :(得分:4)

我自己编写时间选择器而不是iOS8中的UIActionSheet:

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];

UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelBtnPressed:)];

[cancelBtn setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                   [UIColor colorWithRed:253.0/255.0 green:68.0/255.0 blue:142.0/255.0 alpha:1.0],
                                   NSForegroundColorAttributeName,
                                   nil] forState:UIControlStateNormal];

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

UIBarButtonItem *titleButton;

float pickerMarginHeight = 168;


titleButton = [[UIBarButtonItem alloc] initWithTitle:@"title" style:UIBarButtonItemStylePlain target: nil action: nil];

[titleButton 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];

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],
                                 NSForegroundColorAttributeName,
                                 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;
    popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    [popoverController presentPopoverFromRect:CGRectMake(0, pickerMarginHeight, 320, 216) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

UIActionSheet在 iOS8 中已弃用。将 UIAlertController 用于 iOS8或更高版本

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];

我遇到了同样的问题并通过这种方式解决了它,它将适用于所有ios版本

在ios 8中,苹果已经改变了很多东西,我在这里面对我自己的项目中的一个问题所以,我只是想提供替代UIActionsheet的解决方案。

ios 8 UIActionsheet中的

也已弃用,其委托方法也已弃用。而不是具有prefferedstyle的UIAlertController 使用UIAlertControllerStyleActionSheet。你也可以查看这个帖子:

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

此示例适用于ios 8及其早期版本。

<。>在.h文件中声明此变量

我遇到了同样的问题,显示带有UIActionSheet的UIPickerView在iOS 8中不起作用。因为UIActionSheet已弃用,Apple建议使用UIAlertController。所以我们应该绕风。

        [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)];
        }];
    }
}

我认为解决这个问题的全部内容。 快乐的编码!

您可以使用UIAlertController来执行此操作。

@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)
    }

像这样设置pickerView的委托和数据源

class MyViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource

设置委托和数据源功能

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
    }
