自定义节标题uilabel背景和文本 [英] customize section header uilabel background and text

问题描述

我当前正在创建自己的自定义节标题，但是我从未通过代码进行任何文本编辑..而我用来填充自定义标题的新方法正在做一些奇怪的事情，如图所示:

I am currently creating my own custom section headers but I have never dont any text editing via code.. and my new method that I am using to populate my custom header is doing some weird things as shown below

我想将文本更改为白色并稍加粗体，并使白色背景透明.

I would like to change the text to white and be slightly bolder and also make the white background transparent..

这是我用来执行此操作的代码

this is the code I am using to do this

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)];
    [headerView setBackgroundColor:[UIColor grayColor]];

    // Add the label
    UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.5, 20, 20)];

    // do whatever headerLabel configuration you want here


    headerLabel.text = [self tableView:tableView titleForHeaderInSection:section];
    [headerView addSubview:headerLabel];

    // Return the headerView
    return headerView;
}

我已经尝试过了

[headerLabel.backgroundColor:[UIColor clearColor]];

等，但不起作用:(

推荐答案

我想将文本更改为白色...

I would like to change the text to white...

UILabel的textColor属性是您的朋友.

UILabel's textColor property is your friend here.

稍大胆...

没问题！ headerLabel.font = [UIFont boldSystemFontOfSize:mySize];

并设置白色透明背景.

And make a white transparent background.

哇，哇，这是有史以来最糟糕的setter语法！我的主人myLabel.backgroundColor是一个 getter ，更改为:

Whoa, whoa, that is the worst setter syntax ive ever seen!!! My lord, myLabel.backgroundColor is a getter, change:

[headerLabel.backgroundColor:[UIColor clearColor]];

收件人:

[headerLabel setBackgroundColor:[UIColor clearColor]];

对您来说幸运的是，使用您的语法会向nil发送一条消息，这默认将标签的背景色设置为白色.

Lucky for you, using your syntax would have just sent a message to nil, which is defaulting the background color of your label to white.
