I am using following code for that.

我为此使用了以下代码。

UIActionSheet *actionSheet;
NSString *pickerType;

- (void)createActionSheet {

    if (actionSheet == nil) {
        // setup actionsheet to contain the UIPicker
        actionSheet = [[UIActionSheet alloc] initWithTitle:@"Please select" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
        actionSheet.backgroundColor = [UIColor clearColor];

        UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
        pickerToolbar.barStyle = UIBarStyleBlackOpaque;
        [pickerToolbar sizeToFit];

        UIImageView *imageObj = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 40)];
        imageObj.image = [UIImage imageNamed:@"header.png"];
        [pickerToolbar addSubview:imageObj];

        UIButton *cancelBtn = [UIButton buttonWithType:UIButtonTypeCustom];
        [cancelBtn addTarget:self action:@selector(pickerCancel:)forControlEvents:UIControlEventTouchDown];
        // [cancelBtn setImage:[UIImage imageNamed:@"btnInviteCancel.png"] forState:UIControlStateNormal];
        [cancelBtn setTitle:@"Cancel" forState:UIControlStateNormal];

        cancelBtn.frame = CGRectMake(7.0, 7.0, 65.0, 25.0);
        [pickerToolbar addSubview:cancelBtn];

        UIButton *doneBtn = [UIButton buttonWithType:UIButtonTypeCustom];
        [doneBtn addTarget:self action:@selector(pickerDone:)forControlEvents:UIControlEventTouchDown];
        //[doneBtn setImage:[UIImage imageNamed:@"btnInviteDone.png"] forState:UIControlStateNormal];
        [doneBtn setTitle:@"Done" forState:UIControlStateNormal];
        doneBtn.frame = CGRectMake(258.0, 7.0, 55.0, 25.0);
        [pickerToolbar addSubview:doneBtn];

        [actionSheet addSubview:pickerToolbar];
        [pickerToolbar release];


        UIPickerView *chPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 200.0)];
        chPicker.dataSource = self;
        chPicker.delegate = self;
        chPicker.showsSelectionIndicator = YES;
        [chPicker selectRow:0 inComponent:0 animated:YES];
        [actionSheet addSubview:chPicker];
        [chPicker release];

        [actionSheet showInView:self.view];
        [actionSheet setBounds:CGRectMake(0,0,320, 464)];
    }
}

It doesn't work because Apple changed internal implementation of UIActionSheet. Please refer to the documentation:

它不起作用，因为 Apple 更改了UIActionSheet. 请参考文档：

Subclassing Notes

UIActionSheet is not designed to be subclassed, norshould you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

子类化注释

UIActionSheet 不是设计为子类化的，也不应该向其层次结构添加视图。如果您需要呈现比 UIActionSheet API 提供的自定义更多的表单，您可以创建自己的表单并使用presentViewController:animated:completion: 以模态方式呈现它。

Per the Apple docs,

根据Apple 文档，

Important: UIActionSheetis deprecated in iOS 8. (Note that UIActionSheetDelegateis also deprecated.) To create and manage action sheets in iOS 8 and later, instead use UIAlertControllerwith a preferredStyleof UIAlertControllerStyleActionSheet.

重要:UIActionSheet在 iOS 8 中UIActionSheetDelegate已弃用。（请注意，它也已弃用。）要在 iOS 8 及更高版本中创建和管理操作表，请使用UIAlertControllera preferredStyleof UIAlertControllerStyleActionSheet。

Link to documentation for UIAlertController

链接到 UIAlertController 的文档

For example:

例如：

     UIAlertController * searchActionSheet=[UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];

                [ searchActionSheet.view setBounds:CGRectMake(7, 180, self.view.frame.size.width, 470)];

                //yourView represent the view that contains UIPickerView and toolbar
                [searchActionSheet.view addSubview:self.yourView];
                [self presentViewController:searchActionSheet animated:YES completion:nil];

There is out-of-the-box ready solution with exactly the same behaviour - ActionSheetPicker-3.0

有开箱即用的解决方案，具有完全相同的行为 - ActionSheetPicker-3.0

Original version used UIActionsheet, but with iOS 8 release I upgrade this project and replace UIActionsheet with simple view, but animation and view looks exactly the same.

使用原始版本UIActionsheet，但在 iOS 8 版本中我升级了这个项目并用简单的视图替换了 UIActionsheet，但动画和视图看起来完全一样。

That doesn't show anything because uiactionsheet & uiactionsheetdelegate is deprecated is ios8 https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIActionSheet_Class/index.html

这没有显示任何内容，因为不推荐使用 uiactionsheet 和 uiactionsheetdelegate 是 ios8 https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIActionSheet_Class/index.html

You need to use UIAlertController in ios 8.

您需要在 ios 8 中使用 UIAlertController。

Try this when presenting UIActionSheet in last 2 lines:

在最后两行显示 UIActionSheet 时试试这个：

[actionSheet showFromRect:CGRectMake(0,480, 320,215) inView:self.view animated:YES];
[actionSheet setBounds:CGRectMake(0,0,320, 464)];
