変更するサイズは、チケットの数を増加し、私はこの「+」記号で</p> <p><img src="https://i.stack.imgur.com/xMRrL.png" alt="enter image description here"></p> <p>のようなカスタムセルを作成したカスタムセル

Question

の機能を変更します。チケット数が0の場合、「 - 」は無効になり、チケット数が4の場合は「+」が無効になります。これまではうまくいっています。問題は、今度は、4行目の "+"ボタンをクリックするとテーブルのフレームサイズを変更し、4行目の " - "をクリックするとフレームサイズを取り戻したいのです。私はそうすると、「 - 」は、他の列の機能がrandomly.PLeaseは私が私がここwrong.Thanksをやって何を知っているように変更+ボタンの私のコードです

Answer 1

ボタンをクリックしてコードを追加するか、didSelectRowForIndexPathでこのメソッドを使用することもできます。

[self.tableView beginUpdates]; 
[self.tableView endUpdates]; 

これを使用すると、自動的にテーブルビュー呼び出し以下のメソッドが処理されます。

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    return 300;// here you can calculate cell height according to your requirements. 
} 

希望、これは
