        relatedLabel.backgroundColor = UIColor.grayColor()
        relatedLabel.text = info.relatedTitle
    }
}

回答1:

You just need to navigate using didSelectItemAtIndexPath same as Tableview control. Write your Navigation code to didSelectItemAtIndexPath of Collectionview

回答2:

If you are nesting a collection view inside a table view cell and want to trigger an action from the table view displaying this 1st cell, you can do two things.

First

You can use the UICollectionViewDelegate protocol to catch the user interaction with your collection view cell.

Don't forget to set your table view cell as the delegate of its collection view.

Second

You can create your own protocol (useful when a cell have multiple buttons).

Then, each button will have its own “didTap” method, instead of the “didSelect” method from the original collection view delegate.
