New feature: adding delegates

[colasbd]

Hi,

I'm thinking of a new feature: adding a delegate:

@protocol NYSegmentedControlDelegate <NSObject>

- (void)segmentedControl:(NYSegmentedControl *)segmentedControl willSelectIndex:(NSUInteger)index ;
- (void)segmentedControl:(NYSegmentedControl *)segmentedControl didSelectIndex:(NSUInteger)index ;

- (void)segmentedControl:(NYSegmentedControl *)segmentedControl willUnselectIndex:(NSUInteger)index ;
- (void)segmentedControl:(NYSegmentedControl *)segmentedControl didUnselectIndex:(NSUInteger)index ;

@end

What do you think? Good idea? Easy to implement?

If you are OK, I can do a PR.

@colasjojo I'm just facing the exactly same problem as you mentioned above. Have you completed it? Thanks in advance.

Since NYSegmentedControl inherit from UIControl, you can just use UIControlEventValueChanged to get the seg value change.
