UIImageView的initWithImage变形
我正在使用类似于以下的代码从 PNG 图像创建一个计数器：
counterImage = [UIImage imageNamed:@"counter-1-2-inactive.png"];
UIImageView *counterImageView = [[[UIImageView alloc] initWithImage:counterImage] autorelease];
UILabel *countLabel = [[[UILabel alloc] initWithFrame:counterImageView.frame] autorelease];
[cell addSubview:counterImageView];
[counterImageView addSubview:countLabel];
您可以在下面看到结果，在左侧有一个来自 iOS 模拟器的计数器，在右侧有一个原始的 PNG。
为什么生成的 UIImageView 的质量略有下降？我该如何改进它？这可能只是 1 像素高度的线，但在 1:1 比例下，似乎计数器比上面的缩短了。
生成的 counterImageView 的大小与原始 PNG 相同：40x24。
I'm creating a counter from PNG image using code similar to:
counterImage = [UIImage imageNamed:@"counter-1-2-inactive.png"];
UIImageView *counterImageView = [[[UIImageView alloc] initWithImage:counterImage] autorelease];
UILabel *countLabel = [[[UILabel alloc] initWithFrame:counterImageView.frame] autorelease];
[cell addSubview:counterImageView];
[counterImageView addSubview:countLabel];
You can see a result below, on the LHS there is a counter from iOS Simulator and on the RHS there is a original PNG.
Why the quality decreased slightly in the resulting UIImageView? How can I improve it? This is maybe only 1-pixel-height line, but in 1:1 scale is seems like a counter is shortened from the above.
Size of a resulting counterImageView is the same as original PNG: 40x24.

我根据对此问题的评论应用了 1px 透明边框：旋转 UIImageView 是否有快速而肮脏的抗锯齿技术？
