Question

When I hard exit (double click home and minus) and then relaunch app it is freezing up.

The Console shows this:

[app directory path …..]has changed; re-reading symbols.

I think it may have to do with this code in my appdelagate.m

- (void)applicationWillTerminate:(UIApplication *)application
{
    [self saveCode];
}

- (void)saveCode
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);  
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:@"routine.plist"];
    [NSArray writeToFile:path atomically:YES];
}

Answer 1

First: saving a plist to populate a UITableViewController is a really tedious way to save data persistently and an inconsistent one as you may have realized, I would recommend that you use Core Data instead.

Second: Run the debugger (before launching your app) and find any line of text that’s shown in black (grey lines are for methods called by the os and the cocoa layer, black ones are for your own methods). The debugger can be run via Run > Debugger or Command + Shift + Y.
