在iPhone中预览圆形图像 [英] Preview rounded image in iphone

问题描述

任何人都可以告诉我如何在自定义单元格内创建图像预览，其中包含mms中加载的图像的方面。

can anyone tell me how can I create an image preview inside a customized cell with the aspect of the ones loaded in the mms'.

我一直在尝试通过改变IB中的值来做到这一点我无法做到。

I've been trying to do it by changing values in IB and I haven't been able to.

非常感谢！

感谢您的三个答案。

做

cell3.imageView.layer.masksToBounds = YES;
cell3.imageView.layer.cornerRadius = 16;
cell3.imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
cell3.imageView.layer.borderWidth = 1.0; 

我能够做我想要的一部分。但是，我仍然无法在图像上看到发光的样子。现在有人应该控制哪个属性？

I was able to do part of what I want. However, I still can't put that "glow" look on the image. Does anybody now which property should I control?

非常感谢（并再次感谢）。

Thanks a lot (and thanks again).

推荐答案

当然。将QuartzCore框架添加到项目中，然后：

Sure. Add the QuartzCore framework to your project, then:

#import <QuartzCore/QuartzCore.h>
// ...
cell.imageView.layer.masksToBounds = YES;
cell.imageView.layer.cornerRadius = 4;

请注意 cornerRadius 属性仅可用在OS 3.0及更高版本中;如果你支持旧版本（你可能不必这样做），你需要做一些核心图形工作。

Note that the cornerRadius property is only available in OS 3.0 and later; if you're supporting an older version (which you probably don't have to be), you'll need to do some Core Graphics work.
