[I-mobile-u] MIT Mobile iPhone App

[Daniel Mancusi]

Thanks for the response.  We've made quite a few customizations, and I have
only recently attempted to run it on an iOS5+ device, so it may well have
been able to run out of the box.  Luckily, I did figure out at least part
of what was going on today. Here's the relevant part of the crash log:

...

3   CoreFoundation                0x353167ab +[NSException raise:format:] +
35

4   Foundation                    0x31191d15
_NSFileHandleRaiseOperationException + 153

5   Foundation                    0x3116f2a3 -[NSConcreteFileHandle
writeData:] + 131

6   BucknellMobile                0x0002939f MyLog (MITLogging.m:20)

7   BucknellMobile                0x00005137 -[MIT_MobileAppDelegate
application:didFailToRegisterForRemoteNotificationsWithError:]
(MIT_MobileAppDelegate.m:439)

...

It was crashing when the MITLogging class tried to write a message after
the didFailToRegiserForRemoteNotifications handler was called.  I did not
figure out exactly why that was crashing, but since we are not using remote
notifications just yet, I just disabled the attempt to register, and the
app now loads without crashing.  There are still a few more issues, but I
haven't had a chance to look too closely at those yet.

Thanks,
Dan
