UITableViewCellStyleSubtitle标签的BackgroundColor? [英] BackgroundColor of UITableViewCellStyleSubtitle labels?

问题描述

我正在尝试创建一个以图像为背景的表格. 为此，我从背景入手:

I am trying to create a table with an image as a background. To achieve this, I started out with the background:

self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];

这导致背景图像也出现在表格单元格中.那不是我想要的东西，所以我尝试设置单元格的backgroundColor:

This resulted in a background image which appears in tablecells as well. That is not something I want, so I tried to set the cell's backgroundColor:

cell.backgroundColor = [UIColor whiteColor];

这根本没有效果！！！嗯，很奇怪. 所以我尝试了这个:

This had no effect at all !!!. Hmmm strange. So I tried this:

UIView *backgroundView = [[UIView alloc] init];
backgroundView.backgroundColor = [UIColor whiteColor];
cell.backgroundView = backgroundView;
[backgroundView release];

这几乎可行.剩下的唯一问题是textLabel& detailTextLabel仍显示它们后面的背景. 将这些标签上的backgroundColor设置为白色也无济于事.

This works almost. The only problem left is that the textLabel & the detailTextLabel still show the background behind them. Setting the backgroundColor on those labels to white doesn't do anything either.

我该如何进行?我哪里出问题了?我正在尝试实现像worldClock应用程序一样的tableView.

How do I proceed? Where do I go wrong? I am trying to achieve a tableView like the worldClock app has.

推荐答案

要更改表格视图单元格的背景色，您需要将其设置为tableView:willDisplayCell:forRowAtIndexPath:而不是tableView:cellForRowAtIndexPath: 否则不会有任何效果，例如:

To change the background colour of the table view cell, you'll need to set it in tableView:willDisplayCell:forRowAtIndexPath: rather than tableView:cellForRowAtIndexPath: otherwise it won't have any effect, for example:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    cell.backgroundColor = [UIColor whiteColor];
}
