What's the differences between IKImageBrowserView's delegate and _delegate?

Question

As the picture says, there are delegate, _delegate, dataSource, _dataSource, what are the differences?

Basicly, I can use the functions I want with either delegate + dataSource or _delegate + _dataSource, but I don't know what the differences are?

Answer 1

I believe the _delegate outlet is referencing the internal property directly whereas the delegate uses getters/setters.
