Groupon iPhone App: Easy to reproduce crash on the "Select City" screen

Date: 07/30/2013

Description:

I’ve found a very easy way to crash the Groupon iPhone app.

You’ll need a bit of two fingered dexterity in order to activate the crash.  This isn’t the type of crash that a regular user would hit.  It’s a whole lot easier to show than to describe, so please just look at the attached screenshots below if you’re interested.

There’s a city option under the “Featured” heading.  Selecting the city shown will take you to a “Select City” screen.

This “Select City” screen has two buttons at the top of the screen a “Country” button in the upper right and a “Cancel” button in the upper left. 

You can easily get the iPhone app to crash if you press both of these buttons at the same time, let both your fingers linger on the screen for a moment, and then release both of your fingers.

I’ve gotten this to crash the iPhone app numerous times now.

Steps:

1.     Launch the Groupon iPhone App

2.     Select the city option under “Featured”

3.     On the “Select City” screen, press and HOLD the “Cancel” button and the “Country” buttons at the same time

4.     Release the “Cancel” and “Country” buttons at roughly the same time (takes practice)

Result:  There is an easy to reproduce crash on the “Select City” screen – toggling the “Cancel” and “Country” buttons

Expected:  No easy to reproduce crash on the “Select City” screen

Select the city option.

Takes some practice - press and hold the "Cancel" button and the "Country" buttons at the same time.  Then release them at the same time.
