Question

From what I’ve read, this topic has come up several times over the last few years and usually with very vague answers, plus there hasn’t been a mention of it from what I’ve found in over a year so I’m hoping there’s been progress.

Anyway, I currently have an Iphone 4 with IOS 5.0.1 installed, and am having the issue where most applications installed from the App Store are crashing on splash screen. There are many people who say installing a random application from the App Store, reinstalling the app, or restoring your phone completely will fix this problem, but it doesn’t seem to have the same effect anymore (as most of these suggestions were for IOS 4 and 3, not 5).

So, what I’ve done is just trying to find the source of the issues. I’ll be using the popular and well known app UrbanSpoon as my example for the crashes. Below are the syslog and crash report after attempting to run UrbanSpoon. From what I can understand from them, it has something to do with how IOS sandboxes applications, but I can’t figure out which part specifically says what could be causing the crash.

Any help on this is greatly appreciated, hoping these answers will benefit everyone having this issues!

SysLog:

(Snipped from log file from when UrbanSpoon was first executed to the last mention of the application)

EDIT:
Syslog is too big to post here, here’s a link to it instead.

Answer 1

The line: “Application failed to launch on time” seems like the root of the whole thing. It means the application is doing WAY too much work upon startup in the -applicationDidFinishLaunchingWithOptions method. Combine a high loading time with 100% CPU usage, and the app looks like a thrashing bull in a fine china store. And those are the kinds of apps the OS just loves to kill.
