}

else if (indexPath.row == 2){

cell.detailTextLabel.text = @"C";

有一个明显的右支撑不匹配，将您的代码更改为：

if (indexPath.row == 0) {
    cell.detailTextLabel.text = @"A";
}
else if (indexPath.row == 1) {
    cell.detailTextLabel.text = @"B";
...

您可以将其缩短为

cell.detailTextLabel.text = [@"ABCD" substringWithRange:NSMakeRange(indexPath.row,1)];
