Question

How can I catch all the exceptions in an iPhone app and report to a central server?

I want to have access to the exception messages that occurred on devices (all devices that install my app).

In your application delegate you can call NSSetUncaughtExceptionHandler to install a handler to handle uncaught exceptions.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
}

void uncaughtExceptionHandler(NSException *exception) {
    NSLog(@"%s %@", __PRETTY_FUNCTION__, exception);
}
