Pass data Through segue not working in swift 3 any solution?

问题

i have passed data from didselect method of collectionView like this

 func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

        let dicttemp = (arrRespProduct?.object(at: indexPath.row))! as! NSDictionary
        dicData = NSMutableDictionary(dictionary: dicttemp)

         performSegue(withIdentifier: GlobalConstant.segueIdentofier.productDetail, sender: self)
    }

But method

func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) 

is not calling in swift 3... Any solution?

回答1:

prepareForSegue is changed in swift 3.0 so you need to write like this

override func prepare(for segue: UIStoryboardSegue, sender: Any?){

}

回答2:

In addition to above answer you should expect a lot of changes of method names like: prepareForSegue to prepare or String.substringFromIndex to String.substring. The obvious method name endings are ommited/moved to the label of 1'st argument.
