自定义UITableViewCell子类 [英] Customizing an UITableViewCell subclass
问题描述
我想创建一个自定义 UITableViewCell
,它应该具有与默认实现不同的外观。为此,我将 UITableViewCell
子类化,并希望添加标签,文本框和背景图像。似乎只显示背景图像。
也许我完全走错了轨道并且可能继承 UITableViewCell
毕竟是一个坏主意,是否有任何理由为什么会这样,有没有更好的方法?
I would want to create a custom UITableViewCell
which should have a different appearance than the default implementation. For this I subclassed the UITableViewCell
and want to add a label, textbox and a background image. Only the background image seems not to appear.
Maybe I'm completely on the wrong track here and maybe subclassing a UITableViewCell
is a bad idea after all, is there any reason why that would be the case and is there a better way?
无论如何这是我尝试的,在子类的 initWithStyle
我把以下内容:
Anyhow this is what I tried, in the subclass's initWithStyle
I put the following:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self == nil)
{
return nil;
}
UIImage *rowBackground;
backRowImage = [UIImage imageNamed:@"backRow.png"];
((UIImageView *)self.backgroundView).image = backRowImage;
}
我在这里做错了什么?我是否应该在 drawRect
方法中设置背景图像?
What am I doing wrong here? Should I set the background image in the drawRect
method as well?
推荐答案
根据头文件,对于普通样式的表,backgroundView默认为nil。您应该尝试创建自己的UIImageView并将其粘贴在那里。
According to the header file, the backgroundView defaults to nil for plain-style tables. You should try creating your own UIImageView and sticking it in there.
