Question

My app is crashing in the iPad simulator when I press the action button again once it has already been pressed to open my activity view. I am concerned that this will be an issue if the user wants to press the button again to close the Popover rather than touching outside of it. Any suggestions are appreciated 🙂

FYI the Action button is a UIToolbar button.

In the .h

@property (strong, nonatomic) UIPopoverController *popup;
@property (strong, nonatomic) UIPopoverController *activityViewProp;

In the .m:

-(IBAction)openUIActivityView:(id)sender {



    UIActivityViewController *activityView = [[UIActivityViewController alloc]initWithActivityItems:@"Hello World" applicationActivities:nil];


    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        [self presentViewController:activityView animated:YES completion:^{    
        }];
    } else {

self.popup = [[UIPopoverController alloc] initWithContentViewController:activityView];

[self.popup presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES]; }}

Just check if you already have a popup, and do something else

-(IBAction)openUIActivityView:(id)sender {
    if (self.popup) {
        [self.popup dismiss ...];
    }
    else {
        // show popup code
    }
 }
