私は、collectionViewCellのボタンがクリックされたときにViewControllerを表示しようとします。TableViewCellのcollectionViewのcollectionViewCellのボタンがクリックされたときに新しいViewControllerを表示します。
私はdynamic tableViewに、tableViewCellの1つにある動的なcollectionViewを持っています。他のビューコントローラ
を表示するためにあらゆるcollectionViewCellsで
、セグエのトリガーであるべきボタンがあり、私は次のコードが、アプリがクラッシュしてみました：
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<Okm.bienController: 0x7fc8b0cfb1a0>) has no segue with identifier 'extend''
私のstoryBoardのsegue識別子は 'extend'です。私は私のcollectionCellのボタンと機能clickExtendを（）リンク
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.segue()
// self.performSegueWithIdentifier("image", sender: nil)
}
func clickExtend(sender:Int){
print(sender) //print the correct tag!
self.segue()
}
func segue(){
self.performSegueWithIdentifier("image", sender: nil)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "image" {
let backItem = UIBarButtonItem()
backItem.title = ""
navigationItem.backBarButtonItem = backItem
// print(sender)
let extendView = segue.destinationViewController as! extendController
extendView.image = UIImage(named: "maison")
}
}
}
：
class photoCell: UITableViewCell, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate, UICollectionViewDataSource {
...
func extendFunc(sender : UIButton) {
bienController().performSegueWithIdentifier("extend", sender: sender.tag)
}
}
class bienController : UIViewController, UITableViewDelegate, UITableViewDataSource {
...
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "extend" {
let backItem = UIBarButtonItem()
backItem.title = ""
navigationItem.backBarButtonItem = backItem
let extendView = segue.destinationViewController as! extendController
extendView.image = image[sender]
}
}
}
」（私はセグエ識別子変更
を「画像」）。
class photoCategoryCell: UITableViewCell, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate, UICollectionViewDataSource {
...
func extendFunc(sender : UIButton) {
print(sender.tag)
bienController().boo(sender.tag)
}
}
そして：
class bienController : UIViewController, UITableViewDelegate, UITableViewDataSource {
...
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.boo(indexPath.row)
}
func boo(sender:Int){
let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let vc:UIViewController = storyboard.instantiateViewControllerWithIdentifier("extend") as! extendController
let backItem = UIBarButtonItem()
backItem.title = ""
navigationItem.backBarButtonItem = backItem
self.showViewController(vc as UIViewController, sender: nil)
}
}
tableViewCellに私をクリックすると、それは、ビューコントローラを示しているが、私はcollectionViewCellで "拡張" をボタンをクリックすると、何もhappendsません。..
お願いします。私は助けが必要です！
ありがとうございました！最初のケースで

ありがとう@pbasdf！私は何かこれが間違っていると思った：bienController（）。performSegueWithIdentifier（ "extend"、sender：sender.tag）、私は正しかった..しかし、実際に別のView Controllerから関数を正しく呼び出す方法がわからない。私は私のフルコードを追加しました、どのように私はbiogControllerの関数を呼び出すことができますphotoCategoryCellからSegueを実行するには？大いに感謝する！私はこのバグが修正されることを望む！ –
@ L.Valentin私は自分の答えを更新しました。 – pbasdf
こんにちは@pbasdf！私は十分にあなたに感謝できません！それは素晴らしいレッスンでした！ありがとう、今すぐ代議員は私のためにもっと意味がある！クラス名のアドバイスをありがとう！ –
