UIPickerView不能在actionSheet中滚动

Question

我已经在UIActionSheet中添加了一个UIPickerView。一切正常，但是我的选择器不能滚动来选择值。有什么建议吗？

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
UIPickerView * picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 50, 320, 270)]; 
picker.showsSelectionIndicator = YES;
picker.dataSource = self;
picker.delegate = self;
[actionSheet addSubview:picker];
[picker release];

[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0, 0, 320, 500)];
[actionSheet release];

致以最好的问候，多林

您要实现的另一种解决方案是设置文本字段的inputView和inputAccessoryView。设置这些将取代标准键盘，并引入自定义视图。这包括选取器视图。我碰巧在这里用这个question写了一个简短的例子。看一下，看看是否有帮助。
