UISplitViewController中的ActionSheet在纵向模式下的行为与横向模式不同

Question

I created a new application using the Split View-based Application template.

I then added an Action Button to the rootViewController navigation controller called actionButton.

When the button is pressed, I display an ActionSheet like this:

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil 
    delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil
    otherButtonTitles:@"Admin Functions", @"Refresh Data", nil];
[actionSheet showFromBarButtonItem:actionButton animated:YES];
[actionSheet release];

After I press the button when in landscape mode it displays the action sheet in a popover which is pointing to the button (as I expected it to):

However, in Portrait mode it looks completely different and the menu comes up from the bottom of the rootViewController popover just like it does on the iPhone:

My question is, how do I make the ActionSheet appear at the top while in portrait mode, just like it does when in landscape mode?

Since this is a "utility menu", it isn't really tied directly to the data being displayed so it shouldn't be part of the popover.

Answer 1

This behaviour is by design, if it were a popover in portrait mode you would then have 2 levels of popover.

This is technically possible by implementing your own version of UIPopover or using one someone has already written ( WEPopover ).

However, this is a poor design choice. You say that the functions aren't related to the data, however one is 'refresh data'. I would replace the action button with a refresh icon such as the one Apple uses in 'Find my Friends':

The other, 'Admin Functions', if not directly related to the data in the list, perhaps needs a new home, maybe with the main view of your app? It's hard to say where is best to put it without knowing more about the structure.

Answer 2

Another possibility is that you could move the action button from right edge of the root view controller's bar to the left edge of the detail view controller's bar.

For example, if the action button were located just to the right of the vertical bar in your first screen shot (meaning it's at the left edge of the detail view controller's bar), then when you rotate to portrait mode it would appear just to the right of the Events button in your second screen shot. You could still call UIActionSheet's showFromBarButtonItem:animated method, which would display your action sheet in popup mode.

There's still the question of whether you really want two popovers on the screen at the same time. But if you do, this is how to do it.
