這兩天上傳審核遇到點麻煩,打開app加載超時被看門狗kill了，此文記錄自己采坑并解決重新審核通過的經歷，以下是蘋果反饋的問題：

Exception Type:  EXC_CRASH (SIGKILL)
Exception Codes: 0x0000000000000000, 0x0000000000000000

問題提示就是啟動后主線程加載時間過長，被看門口給殺了。現在我們要找到啟動后是什么問題導致加載過長，但面對這些地址符號如何解析呢？
下面介紹一種方法：symbolicatecrash
該方法要用到三個文件
1: dSYM文件----該文件你可以在Xcode->window->organizer里面找到你上次上傳到App Store的包然后右鍵 show In Finder，然后找到該文件再右鍵顯示包內容->找到dSYMs文件夾->找到XXX.app.dSYM文件。
2.crash文件(把蘋果發給你的.txt文件，保存到本地，后綴是.crash)
3.symbolicatecrash工具（終端輸入 find /Applications/Xcode.app -name symbolicatecrash -type f獲取列表，然后復制含有DVTFoundation的路徑，然后前往文件夾copy出來）把這三個東東放在同一個文件夾
然后
打開終端，cd到文件夾，執行

./symbolicatecrash ./5CFEEB3F-8FA3-4522-B0E2-303B0200799A.crash ./xxx.app.dSYM > symbol.crash

如果出現

Error: "DEVELOPER_DIR" is not defined at ./symbolicatecrash line 69.

則先執行

export DEVELOPER_DIR=/Applications/XCode.app/Contents/Developer

再執行

 ./symbolicatecrash ./5CFEEB3F-8FA3-4522-B0E2-303B0200799A.crash ./xxx.app.dSYM > symbol.crash

打開symbol.crash文件
