Question

我在UIToolbar有2个律师无国界组织。每个组织都有一项行动,以启动自己的行动。

现在,如果我在场的话,那就点击了另一个“世界钻石组织”,另一个行动小组也做了介绍,因此,我有两个在屏幕上,它们重叠。我想有人在提出对方时就予以驳回。

I have this code now:

- (IBAction)showFirstActionSheet:(id)sender
{
    if (!self.eRXActionSheet)
    {
        UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"eRX Menu" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"New eRX", @"eRX Refills", nil];
        sheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
        self.eRXActionSheet = sheet;
        [sheet release];

        [self.eRXActionSheet showFromBarButtonItem:sender animated:YES];

        return;
    }

    [self.eRXActionSheet dismissWithClickedButtonIndex:self.eRXActionSheet.cancelButtonIndex animated:YES];
    self.eRXActionSheet = nil;
}

- (IBAction)showSecondActionSheet:(id)sender
{
    if (!self.actionSheet)
    {
        UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"Action Menu" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Help", @"Lock", @"Log Out", nil];
        sheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
        self.actionSheet = sheet;
        [sheet release];

        [self.actionSheet showFromBarButtonItem:sender animated:YES];

        return;
    }

    [self.actionSheet dismissWithClickedButtonIndex:self.actionSheet.cancelButtonIndex animated:YES];
    self.actionSheet = nil;
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (actionSheet == self.eRXActionSheet)
    {
        if (buttonIndex == 0)
        {
            [self erxButtonClicked];
        }
        else if (buttonIndex == 1)
        {
            [self erxRefillButtonClicked];
        }
    }
    else
    {
        if (buttonIndex == 0)
        {
            [self helpButtonClicked];
        }
        else if (buttonIndex == 1)
        {
            [self lockButtonClicked];
        }
        else if (buttonIndex == 2)
        {
            [self logOut];
        }
    }
}

Answer 1

In your code, before creating an action sheet, your are checking if the action sheet to be displayed is not nil. Logically, this will always evaluate to true.

相反,如果other action summary is not nil,你应当加以核对。如果是的话,则予以驳回,并创造新的内容。

-(void)buttonForActionSheet1Clicked {
    if (actionSheet2 != nil) {
        // dismiss it
    }
    // show actionSheet1
}

-(void)buttonForActionSheet2Clicked {
    if (actionSheet1 != nil) {
        // dismiss it
    }
    // show actionSheet2
}

或者,你可以迫使用户在工具栏中首先在disabling上放弃本行动表。

Answer 2

电话:dismissWithClickedButtonIndex:animated: on the actionsheet 你想要解职。

E.g. in showFirstActionSheet add this line to dismiss the other:

if(self.actionSheet) [self.actionSheet dismissWithClickedButtonIndex:<indexofCancelButton> animated:YES];
