Xcode7.3 iOS 9报错

:This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes.  This will cause an exception in a future release.

原因是在线程中做了页面跳转;--UI处理全部都要放到主线程中;

Applications/Xcode.app/Contents/Developer/usr/bin/copypng emitted errors but did not return a nonzero exit code to indicate failure

原因:要么图片格式不正确,要么图片重复
