Question

我在动作表中添加了一个按钮。这很容易，但在我的情况下，有超过5个，Apple在行动表上不接受更多5个按钮。所以我在动作表中添加了一个滚动视图，并向scrollview添加了按钮。但是这个视图有两个固定的按钮取消，另一个带有一些标题。

这是正确的方法吗？

Answer 1

如果您有五个以上的按钮，最好在普通视图中使用自定义的表格视图并提供UIModalTransitionStyleCoverVertical，以便它就像一个操作表

Answer 2

使用以下代码......

- (IBAction)actionsheetbuttonpress:(id)sender {


actionSheet = [[UIActionSheet alloc] initWithTitle:nil 
                                          delegate:nil
                                 cancelButtonTitle:nil
                            destructiveButtonTitle:nil
                                 otherButtonTitles:nil];

[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

UIToolbar *pickerDateToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
pickerDateToolbar.barStyle = UIBarStyleBlackOpaque;
[pickerDateToolbar sizeToFit];



CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

pickerData = [[UIPickerView alloc]initWithFrame:pickerFrame];
pickerData.showsSelectionIndicator = YES;
pickerData.dataSource = self;
pickerData.delegate = self;



[actionSheet addSubview:pickerData];


NSMutableArray *barItems = [[NSMutableArray alloc] init];

UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc]initWithTitle:@"DONE-A" style:UIBarButtonItemStyleBordered target:self action:@selector(DatePickerDoneClick)];
UIBarButtonItem *doneBtn1 = [[UIBarButtonItem alloc]initWithTitle:@"DONE-B" style:UIBarButtonItemStyleBordered target:self action:@selector(DatePickerDoneClick)];
UIBarButtonItem *doneBtn2 = [[UIBarButtonItem alloc]initWithTitle:@"DONE-C" style:UIBarButtonItemStyleBordered target:self action:@selector(DatePickerDoneClick)];



[barItems addObject:doneBtn];
[barItems addObject:doneBtn1];
[barItems addObject:doneBtn2];
//add more two button here...or you can add any no of buttons..

[pickerDateToolbar  setItems:barItems animated:YES];

[actionSheet addSubview:pickerData];
[actionSheet addSubview:pickerDateToolbar];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0,0,320, 464)];
[barItems release];
[actionSheet release];
[pickerData release];

}

希望，这会帮助你......冷静
