iOSアプリケーションの不具合

Question

私はアプリのデバッグに取り組んでいますが、不具合があります。私はアプリやインターネット上でそれを見つけましたが、何も見つかりませんでした。

あなたはそれがその短い時間間隔については、以下のようになります。

以下

からグリッチに到達することができます。

Answer 1

reloadDataに問題がありました。古いコードは、これまで私はそれを変更し、以下の

[weakSelf.collectionView reloadData]; 

のようだった：

[weakSelf.collectionView reloadSections:[NSIndexSet indexSetWithIndex:0]]; 

そして、それは私の問題を解決しました。テキストには不具合がありませんが、写真上の不具合はありません。しかし、それは私がそれを保っているので、涼しく見えた:)

Answer 2

あなたは条件に応じて、多くのカスタムセルを示している場合は、あなたが適切テーブルビューのcells.create共通のUITableViewCellクラス（Inを再利用する必要がありたとえばあなたのケース：HGCell）あなたのニーズに応じて多くのペン先を作成することができます（例えば：HGOtherUserTopInformationCell、HGSeperatorCell ...）。以下のコードは、多くのセルを扱う例を示しています。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    NSString *cellIdentifier = [NSString stringWithFormat:@"Cell%ld",(long)indexPath.row]; 

    NSString *nibName; 

    if(indexPath.item == 0) 
    { 
     nibName = @"HGOtherUserTopInformationCell"; 
    } 
    else 
    { 
     if (indexPath.item % 2 != 0) 
     { 
      nibName = @"HGSeperatorCell"; 
     } 
     else 
     { 
      nibName = @"HGOtherUserPhotoCell"; 
     } 
    } 

    HGCell *cell = (HGCell *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 
    if (cell == nil) { 

     NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:nibName owner:self options:nil]; 

     for (id currentObject in topLevelObjects){ 
      if ([currentObject isKindOfClass:[UITableViewCell class]]){ 
       cell = (HGCell *) currentObject; 
       break; 
      } 
     } 
    } 

    //access the cell property here 
    cell.backgroundColor = [UIColor lightGrayColor]; 

    return cell; 
}
