I can use performSelectorOnMainThread to start a method on appdelegate but how do I make my child view controller “subscribe” to a method on appdelegate?
In this way, there is no appDelegate now other Classes can “subscribe” to the notifications they need.
In addition, I will keep the thread alive, each time a new thread is generated is expensive, only it is generated frequently. I recommend using GCD (iOS 4)
I have a NSAutoreleasePool thread that aims to extract information from a web service, I have good web service code, and I can trigger the thread in the view controller There is no trouble starting up, in fact it works very well.

Using NSNotificationCenter, you can publish good notifications: D
