xcode7 ios9 处理警告 This application is modifying the autolayout engine from a background thread, which can lead to engi

 

使用Xcode7后控制台报，This application is modifying the autolayout engine from a background thread, which can lead to engi....，

字面意思很简单，就是把需要更新UI的代码放在的主线程就好了，个人测试Xcode7中在子线程中更新使用autolayout布局的UI会报此错误，那么还不赶紧检查你的项目里用到的SDWebImage是不是在子线程里更新使用了autolayout布局的imageview?
