I have been slowly learning iPhone development and seem to keep hitting walls where I can't figure out how to do what I want to do the right way :( Basically, I want a class that handles all interactions with the data layer, for example, getting a mutable array of some list of objects from the data store. This is pretty trivial in othe...

When revealing a new view, what are the differences between these two and when would you use each? Also, what's the right way to nest views. for example, I have a UIImageview that animates onto my view and it has a button on it. I want to put that image and the button in their own view, then simply animate the view and have both handled...
So, I've got a one-to-many relationship of Companies to Employees in CoreData (using a SQLite backend on iOS, if that's relevant). I want to create a predicate that only returns Companies that have 0 Employees associated with them. I could do it by getting all the Companies and iterating over them, but that would be (I assume) much slowe...

I have a UIView that I'd like to add several bits of text to. I have used a UITextView but I think that's overkill as it doesn't need to be editable. I thought about using a UILabel or a UITextField, but I don't see how you tell the superview where to position the UILabel or UITextField within itself. I want the lowest footprint objec...

I have found that sometimes during net inconsistency following delegate at server and at client code: - (void)onSocket:(AsyncSocket *)sock willDisconnectWithError:(NSError *)err, does not get called. In this method, at client side, I am disposing socket connection established w...
In Objective-C there is the Alloc/Init metaphor. They've also added a shared convenience method called 'new' that internally just calls both in succession. And if I create a subclass of NSObject called FooClass, FooClass picks up those shared methods, including 'new'. BUT... how the heck is that implemented?? It can't simply delegate...
