无法设置UITableViewCell的背景颜色

Question

我用下面的代码自定义背景颜色：

UIColor *cellBackgroundColor = [UIColor colorWithRed:255.0 green:255.0 blue:255.0 alpha:1.0];
cell.contentView.backgroundColor = cellBackgroundColor;

但是没有出现任何结果。这行代码就运行正常：

cell.contentView.backgroundColor = [UIColor redColor];

这是什么问题？请帮忙解答一下谢谢。

Answer 1

cell.backgroundView.backgroundColor

可以用自定义视图完成

UIView *backgroundViewForCell = [[[UIView alloc] init] autorelease];
backgroundViewForCell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"row-bg.png"]];
UIView *selectedBackgroundViewForCell = [[[UIView alloc] init] autorelease];
selectedBackgroundViewForCell.backgroundColor = [[UIColor blueColor] colorWithAlphaComponent:.2];
cell.backgroundView = backgroundViewForCell;
cell.selectedBackgroundView = selectedBackgroundViewForCell;
