更改 UITableViewCell textLabel 背景颜色以清除 [英] Changing UITableViewCell textLabel background color to clear

问题描述

在我的应用程序中，我有一个带有 customViewCells 的表格视图.我对 UITableViewCell 类进行了子类化，并添加了一个将异步加载的图像，对于我使用的文本 cell.textLabel.text = @"someThext".

In my app I have a table view with customViewCells. I subclassed the UITableViewCell class and added an image that will load async and for the text I use cell.textLabel.text = @"someThext".

对于单元格，背景颜色交替设置为[UIColor darkGrayColor]和[UIColor whiteColor].

For the cells the background color is set alternatively to [UIColor darkGrayColor] and [UIColor whiteColor].

当我在模拟器和手机上运行应用程序时，单元格的 textLabel 背景为白色.我想将它设置为清晰，因为我希望单元格的背景颜色是完整的，而不是一条条，然后是白色，然后是另一条.

When I run the app in the simulator and on the phone the textLabel of the cell has the background white. I want to set it to be clear, because I want the background color of the cell to be full not a strip then white then another strip.

在我自定义单元格的init方法中添加，希望白色会变成红色，但是没有任何效果:

In the init method of my custom cell I added, hoping that the white will turn into red, but it doesn't have any effect:

[self.textLabel setBackgroundColor:[UIColor redColor]];

我也试过:

self.textLabel.backgroundColor = [UIColor redColor];

但这也不起作用...如果我添加一个 UILabel 作为子视图，标签的背景颜色可以设置，但我不想这样做，因为当我旋转手机时，我想要我的标签以自动放大.

But this also didn't work... if I add a UILabel as a subview, the background color of the label can be set, but I don't want to do that because when I rotate the phone I want my labels to auto enlarge.

任何想法为什么设置 cell.textLabel 的背景颜色不起作用?

Any ideas why setting the background color of cell.textLabel doesn't work?

谢谢

推荐答案

问题是 UIKit 在 -setSelected 方法中设置了单元格背景色.我有这个方法，但没有 self.textLabel.backgroundColor = [UIColor clearColor];self.detailTextLabel.backgroundColor = [UIColor clearColor];在里面，所以我添加了它们，图片中提到的问题得到了解决.

The problem is that UIKit sets the cell background color in the -setSelected method. I had the method but didn't have self.textLabel.backgroundColor = [UIColor clearColor]; self.detailTextLabel.backgroundColor = [UIColor clearColor]; in it so I added them and the problem mentioned in the picture was fixed.

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
    self.textLabel.backgroundColor = [UIColor clearColor];
    self.detailTextLabel.backgroundColor = [UIColor clearColor];
}
