ios - for 循环的最后一条记录在每个 Cell forRowAtIndexPath 处重复

Question

这里的小错误可能是愚蠢的。我正在从文档目录中读取文件。我根据特定键的值过滤结果。以及我在 UITableView 中呈现的特定值内具有特定字符串的任何内容。行数已正确填充，但 cell.textLabel.text 未在每个单元格 rowForAtIndexPath 处显示正确的名称。我的问题是，我是否正确地迭代了我的循环？由于 indexPath，我是否错误地设置了 textLabel？我附上了输出的屏幕截图和 NSLog 语句，显示了该特定对象的假定 indexPath。下面是显示 RowAtIndexPath 的 willDisplayCell 的代码片段。

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row%2 == 0) {
    UIColor *altCellColor = [UIColor colorWithWhite:0.7 alpha:0.2];
    cell.backgroundColor = altCellColor;
    }

for (int objectToDisplay = 0; objectToDisplay<[tableDataSourceArray count]; objectToDisplay++) {
    NSLog(@"%lu", (unsigned long)objectToDisplay);
    NSString *objectTitle = [[tableDataSourceArray objectAtIndex:objectToDisplay] valueForKey:@"ConnectabilityObjectTitle"];
    NSString *pingResult = [[tableDataSourceArray objectAtIndex:objectToDisplay] valueForKey:@"ConnectivityPingTestResultValue"];
    NSString *portConnectResult = [[tableDataSourceArray objectAtIndex:objectToDisplay] valueForKey:@"ConnectivityPortConnectResultValue"];

    if ([pingResult containsString:@"Successful"]) {
        if ([portConnectResult isEqualToString:@"Successful"]) {
        } else {
            cell.textLabel.text = objectTitle;

            cell.detailTextLabel.text = @"Failed to connect to port for this server/service";
            NSLog(@"%@ at row %lu", objectTitle, (unsigned long)objectToDisplay);
        }
    } else {
        cell.textLabel.text = objectTitle;
        cell.detailTextLabel.text = @"Failed to ping this server/service";
    }
  }
}

这是来自控制台的 NSLogStatement。

这是截图。

Answer 1

从您的代码中删除 for 循环。
因为它总是会在你的 datasourceArray 中分配最后一个值并使用

[tableDataSourceArray objectAtIndex:indexPath.row]

代替

[tableDataSourceArray objectAtIndex:objectToDisplay]
