Question

I have a requirement in an application where I need to be able to add otherButtonTitles dynamically, dependent upon some BOOL switches that a user has specified in the settings. However, I can’t seem to figure out how to go about doing this in the UIActionSheet initialization. I’ve tried to pass a NSString array (NSString[2]), and also a NSArray without any luck.

Any help here is greatly appreciated.

The easiest way to do this that I have found is initially create your action sheet with no buttons, including no cancel or destructive button:

UIActionSheet* actionSheet = [[UIActionSheet alloc] initWithTitle:@"Dynamic"
                                                        delegate:self
                                               cancelButtonTitle:nil
                                          destructiveButtonTitle:nil
                                               otherButtonTitles:nil];

Then add a load of buttons as needed:

if(buttonX)
{
    [actionSheet addButtonWithTitle:@"Button X"];
}
if(buttonY)
{
    [actionSheet addButtonWithTitle:@"Button Y"];
}
if(buttonZ)
{
    [actionSheet addButtonWithTitle:@"Button Z"];
}

Then finally add the cancel button at the end and set the cancel button index:

[actionSheet addButtonWithTitle:@"Cancel"];
actionSheet.cancelButtonIndex = actionSheet.numberOfButtons - 1;

Of course you can add both a cancel button and/or a destructive button in this way.
