Question

I am not able to understand difference between calling a function in background like

[self performSelectorInBackground:@selector(getFriendFaceBookList) withObject:nil];

and calling the same function in a Thread :

[NSThread detachNewThreadSelector:@selector(getFriendFaceBookList) toTarget:self withObject:nil];

Which one is the best way to work in non ARC app.

Thanks

Answer 1

They’re identical. See Documentation

performSelectorInBackground:withObject: The effect of calling this method is the same as if you called the detachNewThreadSelector:toTarget:withObject: method of NSThread with the current object, selector, and parameter object as parameters.

Hope it helps.
