ios - 设置 AccessoryType 破坏 UITableViewCell

Question

我使用自定义表格单元格，标签和图像与标签相连。

如果我添加

[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]

它破坏了我的表格 View 。图像破坏和背景颜色。

区别如下:

有人知道问题出在哪里吗？谢谢

    static NSString *CellIdentifier = @"TableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

您需要设置单元格的背景颜色，而不是 contentView，但这在 cellForRowAtIndexPath 中不起作用。它需要在 willDisplayCell:forRowAtIndexPath:

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    cell.backgroundColor = indexPath.row % 2? [UIColor colorWithRed:228.0/255.0 green:244.0/255.0 blue:199.0/255.0 alpha:1]:[UIColor whiteColor];
}

就图像被压扁而言，这与 subview 的大小及其约束有关。我认为您可以通过为两个标签(上下一对)提供宽度限制来解决这些问题，但使它们的优先级 <1000，因此当添加附件 View 时，这些标签的宽度会变小。同时给左边的 ImageView 一个固定的宽度。
