集合視圖中的兩個定向單元格，如何獲取單元格標題？

Question

你好我想在UICollectionView裏面得到單元格的標題，我內部有1個單元格UICollectionView單元格有類別數組當我點擊UICollectionView項目我想要單元格的標題。我的代碼在這裏。

視圖控制器細胞

import UIKit 

class ViewController: UIViewController { 
    var categories = ["A", "B", "C", "D", "E"] 
} 

extension ViewController : UITableViewDelegate { } 

extension ViewController : UITableViewDataSource { 

    func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? { 
     return categories[section] 

    } 

    func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
     return categories.count 
    } 

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     return 1 
    } 

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! CategoryRow 
     return cell 
    } 

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 

     print(indexPath.row) 

    } 

} 

UICollectionView 


import UIKit 

class CategoryRow : UITableViewCell { 
    @IBOutlet weak var collectionView: UICollectionView! 
} 

extension CategoryRow : UICollectionViewDataSource { 


    func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
     return 12 
    } 

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { 
     let cell = collectionView.dequeueReusableCellWithReuseIdentifier("videoCell", forIndexPath: indexPath) as! VideoCell 
     return cell 
    } 

} 

extension CategoryRow : UICollectionViewDelegateFlowLayout { 


    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize { 
     let itemsPerRow:CGFloat = 4 
     let hardCodedPadding:CGFloat = 5 
     let itemWidth = (collectionView.bounds.width/itemsPerRow) - hardCodedPadding 
     let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding) 
     return CGSize(width: itemWidth, height: itemHeight) 

    } 


    //MARK :- UICollectionViewDelegate 
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { 


    print(indexPath.row) // HERE gives collection view number when clicked BUT I WANT TO Get cell title which inside categories ARRAY example: A/3, B/5 



    } 




} 

底側I標記

打印（indexPath.row）//這裏給出點擊時集合視圖數，但我想獲取其內部類別細胞標題ARRAY示例：A/3，B/5

我想在那裏看到行動，感謝您的幫助！

Answer 1

我想你需要標題protpery添加到您的類

CategoryRow : UITableViewCell { 
    var title: String? 
    @IBOutlet weak var collectionView: UICollectionView! 
} 

，你需要在CategoryRow

func prepareForReuse() { 
    super.prepareForReuse() 
    title = nil 
} 

在ViewController集中添加方法這個標題細胞

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! CategoryRow 
     let titleFromCategories = categories[indexPath.row] as? String 
     cell.title = titleFromCategories 
     return cell 
    } 

和在CategoryRow執行如下

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { 
     let yourString = title + String(format: "/%d", indexPath.row) 

     print(yourString) // HERE gives collection view number when clicked BUT I WANT TO Get cell title which inside categories ARRAY example: A/3, B/5 

} 

Answer 2

從陣列獲取的標題如下：

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { 
    let title = String(format: "%@/%d", categories[indexPath.row], indexPath.row) 
    print(title) 
}
