First of all, I've found a similar question but it does not do the exact same thing I want: UIStoryboardPopoverSegue opening multiple windows on button touch
I have a tool bar with a button that presents a popOver, all wired up with the storyboard.
The problem is that each time I press a button, a new popOver comes up, over the previous one.
In the other question, they suggest this code:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue isKindOfClass:[UIStoryboardPopoverSegue class]]){
// Dismiss current popover, set new popover
[currentPopover dismissPopoverAnimated:YES];
currentPopover = [(UIStoryboardPopoverSegue *)segue popoverController];
}
}
But what it does is, when you press the button, it dismisses the previous popOver (if there's one) and continues with the segue to show a new popOver.
What I want to do is for the button to act as a toggle, meaning that it dismisses the popOver if there's one (not showing a new one) and shows a popOver if there's not one already.
That, by the way, is how it used to work for me without the storyboard.
