使用iPhone 4 Retina Display的colorWithPatternImage（image@2x.png） [英] colorWithPatternImage with iPhone 4 Retina Display (image@2x.png)
问题描述
感谢每当我输入@ 2x时SO的搜索功能爆炸，很难说这是否已被问过......
Thanks to SO's search function blowing up whenever I enter "@2x", it's difficult to tell whether this has already been asked...
我去过使用colorWithPatternImage：为我的各种视图构建平铺的背景图像。然而，当在新的iPhone 4显示器上观看时，这些可以预测看起来像垃圾。所以我已经构建了我的tile.png文件的@ 2x版本，但是colorWithPatternImage：显然无法正确处理UIImages的两倍规模。
I've been using colorWithPatternImage: to build tiled background images for my various views. However, these predictably look like trash when viewed on the new iPhone 4 display. So I've built @2x versions of my tile.png files, yet colorWithPatternImage: evidently can't properly handle UIImages with double the scale.
是否有人有效开发了解决此问题的方法？也许在CoreGraphics框架内（其中，我是新手）？
Has anyone effectively developed a workaround for this issue? Perhaps within the CoreGraphics framework (of which, I'm quite the novice)?
推荐答案
我相信这是一个错误SDK。 colorWithPatternImage：使用高清图像做了一些奇怪的事情。它上面有一个小的关于Apple Dev论坛的主题，但基本上我认为这是一个错误。不确定Apple是否还清楚它。
I believe this is a bug with the SDK. colorWithPatternImage: is doing strange things with the HD image. There's a small thread on the Apple Dev Forums on it, but basically I think it's a bug. Not sure if Apple are aware of it just yet.
我通过在中的视图的子类中绘制模式来解决这个问题 - drawRect：。
希望这会有所帮助。
- (void)drawRect:(CGRect)rect {
[[UIImage themeImageNamed:@"UIBackgroundPattern.png"] drawAsPatternInRect:rect];
}
