iPad app crashes on receiving multiple notifications

Question

I have an iPad app in which users can share images and receive notifications. When the user sure something twice simultaneously with another user, the receiver gets two notifications, each one regarding the share. It then asks if it has to ignore or load the shared image. In case I ignore the first notification and click on load in second notification, my app crashes.

I want to debug this by enabling zombies but notifications are not received on simulator. I have o test it on device only. Is there any way where in I can enable zombies on my device and test it? Can anyone suggest me a better approach to test an app running on device. Thanks!

Answer 1

To enable Zombies select the scheme for your device in Xcode with the toolbar with the dropdown box above where it says "Scheme". Then click "Edit Scheme..."

In the sheet that pops down, select the "Diagnostics" item, and "Enable Zombie Objects".

Then when you build and run that scheme Zombies will be enabled.
