Thanks for test! Could you post your avatar's URL here?

Please let me know if version 0.3.6 fixed this issue.

CodeEagle · Answer 4 · Wed Oct 21 2015 18:58:26 GMT+0800 (China Standard Time)

this still not work @ 0.3.6

CodeEagle · Answer 5 · Wed Oct 21 2015 20:00:57 GMT+0800 (China Standard Time)

这个实现的是否能取代当前的方法呢？
https://github.com/Alamofire/AlamofireImage/blob/master/Source/UIImage%2BAlamofireImage.swift

line 213

    UIGraphicsBeginImageContextWithOptions(size, false, 0.0)

    let scaledRadius = divideRadiusByImageScale ? radius / scale : radius

    let clippingPath = UIBezierPath(roundedRect: CGRect(origin: CGPointZero, size: size), cornerRadius: scaledRadius)
    clippingPath.addClip()

    drawInRect(CGRect(origin: CGPointZero, size: size))

    let roundedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return roundedImage

@CodeEagle 请运行项目的 Demo，在 "Contacts" 里，最后两个是你提供的头像，样式为圆形，它们的格式正确吗？或者你自行调整至你需要的样式看看。我暂时无法重现这个 bug。

hi,运行效果如下，最后一个是不行的。

@CodeEagle 请问你测试机的 iOS 版本是多少？

CodeEagle · Answer 9 · Thu Oct 22 2015 10:39:59 GMT+0800 (China Standard Time)

@nixzhu 一直是用模拟器测试，

真机测试没问题，模拟器不通过

Kevin · Answer 10 · Sat Oct 31 2015 04:44:58 GMT+0800 (China Standard Time)

@CodeEagle 试试把模拟器上的 App 删掉重新打开看效果，可能是缓存

CodeEagle · Answer 11 · Sat Oct 31 2015 12:00:34 GMT+0800 (China Standard Time)

@kevinzhow 不行，下载 Repo，运行，没有 Cache 的
