나는 Instagrams API를 호출하여 일부 이미지를 구문 분석 한 다음 instagrams app와 같은 사각형 모음으로 채 웁니다. 프로그래밍 방식으로 내 콜렉션 뷰 셀 중 하나를 탭하면 새로운 "세부적인 뷰 컨트롤러"로 어떻게 연결합니까?

Answer 1

는 해당의 ViewController에 (또는 뭔가 유사한 이름)을 UICollecitonViewDelegate을 추가하고이 방법을 정의 할 필요가 : 그 새로운 컨트롤러에 데이터를

//MARK: - UICollectionViewDelegate 

func collectionView(collection: UICollectionView, selectedItemIndex: NSIndexPath) 
{ 
    //As sender send any data you need from the current Selected CollectionView 
    self.performSegueWithIdentifier("identifier", sender: self) 
} 

이제 단지를 통해하자를하거나 SegueController을 얻고 설정하는 것이 너는 필요해.

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) { 
    segue.desntinationViewController as MySegueViewController//(Your Segue View Controller) 
     // pass data to next view 


} 

PS : 난 내 맥에 아닙니다 때문에 올바른 이름을 결정하는 데 도움이 할 수있는 편집기 나 텍스트 Completer를 사용하십시오 메소드의 이름에 대한 몇 가지 구문 오류가있을 수 있습니다.

그러나 이것으로 Segue Controller를 호출하면됩니다. 또한 Storyboard 파일에 Segue 식별자 이름을 설정해야합니다. 그렇지 않으면 올바르게 작동하지 않습니다.

Answer 2

1 단계 : creat var indexPath : IndexPath? 및 배열은 상세보기 페이지에서 이미지를 유지

2 단계 : 그래서 응용 프로그램은 "detailedViewController"에 segueing 그러나 나는 통과를 어떻게 알 수 있습니까 가지고

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

    if let detailPage = segue.destination as? DetailPage { 
     let cell = sender as! MyCollectionViewCell 
     let indexPath = self.MyCollectionView.indexPath(for: cell) 
     detailPage.indexPath = indexPath 
     detailPage.YourArray = self.YourDetailPageArray 
    } 
}
