reading a value from preferences - objective-c

Question

I have just recently implemented the inAppSettings kit. My goal was to load my default view and then add a navigation bar button item to the right called "settings". Once the user pressed the settings button it would take them to my settings bundle where they would make a choice to which website they wanted, and then press back which would load up my default view once again with webview loaded once again with the new url.
I have implemented everything that I just described above but once the selection is made within the settings and the user presses back (aka dismisses the settings view to go back to the default view), the app crashes and I have no idea why. My code is below and if anyone knows why this is happening, it would be much appreciated. Let it be noted that once I run the app again after it crashes, the website loads correctly based on the settings they chose before it crashed.
P.S. the options the user can click to select are: Google, stackoverflow.

Answer 1

Do you implement the InAppSettingKit delegate? Add this to your current class above
- (void)settingsViewControllerDidEnd:(IASKAppSettingsViewController *)sender
{
// dismiss the view here
[self dismissModalViewControllerAnimated:YES];
// do whatever you need to do
}
