Base Info for this issue

圆角性能问题

  1. ChatKit Version：0.7.20
  2. App-ID: XX
  3. Language：Objective-C
  4. iOS System Version：iOS10
  5. Prototype（是否是真机）：YES
  6. Issue Type：Bug、

1. How to repeat the problem.

LCCKChatMessageCell cell中源码当开启圆角时CPU飙升不下（6s机器占用98+，且界面绘制完成不下降）， LCCKAvatarImageViewCornerRadiusBlock avatarImageViewCornerRadiusBlock = [LCChatKit sharedInstance].avatarImageViewCornerRadiusBlock; if (avatarImageViewCornerRadiusBlock) { CGSize avatarImageViewSize = CGSizeMake(kAvatarImageViewWidth, kAvatarImageViewHeight); CGFloat avatarImageViewCornerRadius = avatarImageViewCornerRadiusBlock(avatarImageViewSize); self.avatarImageView.lcck_cornerRadius = avatarImageViewCornerRadius; } 在instrument中仔细查找关键原因 self.avatarImageView.lcck_cornerRadius = avatarImageViewCornerRadius; 所执行的代码占绝大部分资源，改为 _avatarImageView.layer.cornerRadius = avatarImageViewCornerRadius; _avatarImageView.clipsToBounds = YES; CPU下降为30左右，绘制完成CPU资源释放。

建议改下

self.avatarImageView.lcck_cornerRadius主要是在做圆角的异步渲染，使用GCD的global的方式进行异步渲染。但是，我推测主要是没考虑到线程切换的代价。后期优化下。

关于头像圆角这个问题 现在仍然存在 0.8.16 并且我更新到0.9.0最新版以后 提示LCCKConstants的第155行 static AVIMMessageMediaType const kAVIMMessageMediaTypeSystem = -7; 这句话报错
