iPhone，我如何使字体尺寸在actionsheet按钮中更小?

I want to make the font size smaller for the text in the buttons of my action sheet as my text is longer than the width.

我想让字体大小为我的行动表的按钮中的文本，因为我的文本比宽度长。

How can I make the font size smaller?

如何使字体尺寸更小?

I'm guessing as you can add things like picker views to action sheets that I may need to add my own buttons to the action sheet, if so how ?

我猜您可以在动作表中添加picker视图之类的东西，如果可以，我可能需要在动作表中添加我自己的按钮。

I need an example.

我需要一个例子。

EDIT: I've made a little progress, but the actual button isn't shown, but you can see it working with the change in the button text when you click on it.

编辑:我已经取得了一些进展，但是实际的按钮并没有显示出来，但是当你点击它时，你可以看到它与按钮文本中的更改一起工作。

        UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                          delegate:self
                                                 cancelButtonTitle:@"Cancel"
                                            destructiveButtonTitle:nil
                                                 otherButtonTitles:@"OK",nil];    

        CGRect frame = CGRectMake(100.0, 80.0, 100.0, 40.0);

        UIButton *pickerView = [[UIButton alloc] initWithFrame:frame];

        [pickerView setTitle:@"FRED" forState:UIControlStateNormal];

        [pickerView setTitle:@"Go Back" forState:UIControlStateNormal];
        [pickerView setTitleColor:[UIColor blackColor] forState:UIControlEventTouchDown];
        pickerView.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
        pickerView.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
        //[removeButton addTarget:self action:@selector(buttonEvent:) forControlEvents:UIControlEventTouchDown];
        [pickerView setBackgroundColor:[UIColor blueColor]];


        [menu addSubview:pickerView];
        [menu showInView:self.view];        

        [pickerView release];
        [menu release];

You may be able to do this directly, but note that actionsheet buttons are not standard UIButtons, but are their own special private control subclass. For this reason, when I need to customize an action sheet, I add my own custom subview to the UIActionSheet and then resize the sheet to match. The downside is that to match the look and feel I need a custom button image background. I adapted (but didn't check in a compiler) this example from Fitting a UIDatePicker into a UIActionSheet. Instead of the picker, just add your xib created UIView.

您可以直接这样做，但是请注意，actionsheet按钮不是标准的UIButtons，而是它们自己的专用私有控件子类。出于这个原因，当我需要自定义操作表时，我将自己的自定义子视图添加到UIActionSheet中，然后调整该操作表的大小以匹配。缺点是为了匹配外观和感觉，我需要一个自定义按钮图像背景。我修改了(但没有检查编译器)这个例子，将一个UIDatePicker安装到一个UIActionSheet上。而不是选择器，只是添加您的xib创建的UIView。

UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[myUIActionSheet addSubview:pickerView];
[myUIActionSheet showInView:self.view];        
[myUIActionSheet setBounds:CGRectMake(0,0,320, myUIActionSheet.bounds.size.height + pickerView.bounds.size.height)];

CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = - pickerView.bounds.size.height; //you may need to change this offset
pickerView.bounds = pickerRect;

[pickerView release];
[myUIActionSheet release];

EDIT: To include a subview from a xib, add a UIView to the top level of the xib and wire it to a UIView property in your controller just as if it was a normal interface component. Within your controller, it will now be available.

编辑:要包含来自xib的子视图，将UIView添加到xib的顶层，并将其连接到控制器中的UIView属性，就像它是一个普通的接口组件一样。在您的控制器中，它现在是可用的。

You can also wire button actions normally instead of using the action sheet callback. You will need to close the action sheet after the press with something like [myUIActionSheet.dismissWithClickedButtonIndex:0 animated:YES]; I think that dismissing it as if it is modal will also work, IIRC.

您还可以正常地连接按钮操作，而不是使用操作表回调。您将需要在按下之后使用类似[myUIActionSheet]的东西来关闭动作表单。dismissWithClickedButtonIndex:0动画:是的);我认为把它看成是模态的也可以，IIRC。
