Question

我想使用此代碼重新加載我的CollectionView的一些細胞的CollectionView reloadData問題，

var indexPathsToReload = [NSIndexPath]() 
     for var i in 0..<Data.NearByList.count { 
      indexPathsToReload.append(NSIndexPath(forItem: i, inSection: 0)) 
     } 

     collview.reloadItemsAtIndexPaths(indexPathsToReload) 

它在Xcode的模擬器進行測試時，工作正常，但是當我建立它在我的iOS設備上我有此錯誤`

*終止應用程序由於未捕獲的異常 'NSInvalidArgumentException'，原因是： ' - [__ NSStackBlock__ _FBSDisplayDidPossiblyConnect：withScene：]：無法識別的選擇發送到實例0x41ca6c' *第一擲調用堆棧： （0×27 99386b 0x39092dff 0x27999035 0x27996c8f 0x278c62b8 0x2c2387d3 0x2c238379 0x2bb09dc3 0x2c241e7b 0x2bc82b45 0x2c2435fd 0x2bab3abd 0x2c242e25 0x2c2413fd 0x2bc7ea1d 0x199654 0x19971c 0x2babd5e3 0x2babdb63 0x2bddda0d 0x2bee9e19 0x2bde0e7d 0x2bbcddff 0x2bbcdc35 0x2bbcd7af 0x2bbcd34b 0x2badea99 0x2bade993 0x2b3741a7 0x1483dab 0x1488829 0x27956595 0x27954a8f 0x278a71e9 0x278a6fdd 0x30b4baf9 0x2bb0c18d 0x1b86dc 0x397bd873） 的libC++ abi.dylib：與終止類型NSException`

Updated這裏捕獲的異常是主要的例外

我下載中心圖片asyncronously每下載圖像後引發該事件與SwiftEventBus和重裝的CollectionView

SwiftEventBus.onMainThread(self, name: "ReloadHomePage") { result in 
      let id=result.object as! Int 

      self.collview.reloadData() 

      // self.collview.reloadItemsAtIndexPaths([NSIndexPath(forItem: id, inSection: 0)]) 


     } 

但有些細胞不會出現像圈子，我必須滾動，使他們right.I要重新加載索引路徑爲此，此錯誤出現

Answer 1

您可以請發表更多的代碼？ collview的類型是什麼？ 你在上面的代碼中看到選擇器異常嗎？ 如果是，哪個是錯誤的選擇器名稱？ 我懷疑選擇器問題與上面的代碼無關。

將更新此答案，如果我得到更多的細節:)
