私は多くの問題に直面しています..私はios開発に慣れていないので、助けていただければ幸いです。
問題1
カスタムセルの黄色と青の画像の上にN個の画像ビュー+ラベルを表示したい。
すべての行に表示される画像ビューの数を解析する必要があり、それに応じて、カスタムセルのすべての画像ビューに画像を割り当てる必要があります。どうやってやるの？データベースから画像リンクを取得して配列に保存しますが、特定の画像ビューにリンクを連続して適用するにはどうすればよいですか。
iOS のユーザー インターフェイスの上に構築するためのヒントが必要です。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifierLeft = @"lefthand";
static NSString *CellIdentifierRight = @"righthand";
if (indexPath.row % 2 == 1) // to get two custom cell vice versa.
{
LeftCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierLeft];
if (LeftCell == nil)
{
LeftCell = [[customCellLeft alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifierLeft row:indexPath.row];
LeftCell.scrollView = [[cellScrollViewClass alloc] initWithFrame:CGRectMake(0,14,1024,187)];
}
LeftCell.videoImageView1.tag=[ImageLinkArray objectAtIndex:indexPath.row];
LeftCell.label1.text=[TitleArray objectAtIndex:indexPath.row];
return LeftCell;
}
else
{
RightCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierRight];
if(RightCell == nil)
{
RightCell =[[customCellRight alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifierRight];
RightCell.scrollView = [[cellScrollViewClass alloc] initWithFrame:CGRectMake(0,14,1024,187)];

RightCell.videoImageView1.tag=[ImageLinkArray objectAtIndex:indexPath.row];
