I have problem in matchapp code at leason 26.
I write flipUp function. When i run the program, when i clicked the card, nothing flipup.
But when i clicked the next card, before card just flipup.
I cannot found the error, i check the code look as same with the tutorial.
Can you post screenshots of your code so that we can see what you have tried to do.
The last collectionView method in the attached screenshot is
didDeselectItemAt and is the wrong one. You should be able to change that to
didSelectItemAt and that should solve the problem.
it solved perfectly.
thanks you @Chris_Parker .
