UITableViewCell中的UIButton操作選擇了錯誤的行

Question

當我選擇這些UITableViewCells中的按鈕時，該按鈕有時會傳遞錯誤行中的數據。在這個表格視圖中，有10個部分，每個部分都有一個部分標題和只有1行。行高佔據了屏幕的大部分，因爲其中有6個按鈕。每選中一個UIButton時，都會打開一個新的viewcontroller，其中放大了按鈕圖像的視圖（刪除此代碼以使其更具可讀性）。

下面是問題：每個按鈕成功推動一個模式viewcontroller;然而，當我向下滾動時，按鈕有時會傳遞來自其下方部分的相同按鈕的數據（例如，點擊時第4節中的button1可能會傳遞第5節中button1的數據）。同樣，當我向後滾動時，按鈕有時會傳遞來自其上方相同按鈕的數據（例如，點擊時，第7節中的button5可能會傳遞第6節中button5的數據）。

我想這個問題是因爲iPhone拉最近加載的單元格（當調用cellForRowAtIndexPath時），但我希望它傳遞按鈕所在行的數據。

想法？預先感謝您提供的任何幫助。

編輯：添加的數據代碼的要求

Answer 1

是的，你可以從哪個按鈕錄製特定的細胞。在IBAction爲方法寫，你會在indexPath對象中獲取特定的細胞錄音按鈕

UIView *senderButton = (UIView*) sender; 
     NSIndexPath *indexPath = [(UITableView *)self.superview indexPathForCell: (UITableViewCell*)[[senderButton superview]superview]]; 

希望這將有助於

Answer 2

有時它標註的問題。

更改標籤是這樣的：

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 

    UIButton *button1 = [[UIButton alloc] init]; 
    button1.tag = indexPath.section + indexPath.row + 8956;// 8956 is some random weird  number 
    [cell.contentView addSubview:button1]; 
    [button1 release]; 

// same code for other buttons 

} 

UIButton *button1 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row + 8956]; 
UIButton *button2 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row +8956]; 
UIButton *button3 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row +8956]; 
UIButton *button4 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row +8956]; 
UIButton *button5 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row +8956]; 
UIButton *button6 = (UIButton *)[cell.contentView viewWithTag: indexPath.section + indexPath.row +8956];
