注意：crash_log一定要和打包时的archive对应上；
方法1）在Orgnizer里找到某一个archive，即：/Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive
找到/Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive/dSYMs/sohunews.app.dSYM/Contents/Resources/DWARF/sohunews
然后在terminal里运行 atos -o /Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive/dSYMs/sohunews.app.dSYM/Contents/Resources/DWARF/sohunews -arch armv6 16进制内存地址

方法2）把/Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive/Products/Applications/sohunews.app和/Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive/dSYMs/sohunews.app.dSYM拷到同一个目录，然后运行：
atos -o /Users/handywang/Library/Developer/Xcode/Archives/2012-04-20/sohunews 4-20-12 3.07 PM.xcarchive/Products/Applications/sohunews.app/sohunews -arch armv6 16进制内存地址
