Best way to wait app Launch

I have an app that requests from the server some data on xml type. Ok, it does ok. But seems this action loads a little the app on launching.

TBXML *tbxml = nil;
tbxml = [[TBXML tbxmlWithURL:[NSURLURLWithString:@"http://www.someplace.com/test/test.xml"]] retain];

So, what i figured is make the app wait to launch completely to do this action. So, i've search for it, and 开发者_StackOverflow社区find two ways.

• applicationDidFinishLaunching;
• awakeFromNib;

I dont know if this is the correct way to do this. So, im open to suggestions.

Thanks!

First, I would suggest you to put that XML loading code in a separate thread using NSOperationQueue or NSThread so that it won't block the main thread.

applicationDidFinishLaunching, IMHO, should be used to initialize your RootViewController, handle incoming push notifications, local notifications, etc. Use viewDidLoad in RootViewController for your purpose.
