iOS Question about the delegate

[Raima]

Hi Guys,

Just a question about the delegate, or deleagates.

Is it possible to have more than one delegate, or are you restricted to one?

Thanks in advance

No, you cannot set more than one delegate on any class I've ever seen. If you want to do this you will have to provide your own class that you set as the delegate which then mediates between all the delegates you wish to set. You will have to thing very carefully about this: if two delegates both implement the same delegate method which do you call?

So does this mean if you have 4 classes, you can potentially have 4 delegates?

4 instances. Each instance of a class can have a different delegate.
