iOS如何解析crash文件中的地址

1.目录中存放app文件

2.打开文件

3.执行命令otool -arch arm64 -l ./QQStock | grep -B 1 -A 10 "LC_SEGM" | grep -B 3 -A 8 "__TEXT"

4.解析命令xcrun atos -arch arm64 -o ./QQStock 0x100633614

lideiMac:4.0.1 lixiang$ cd /Users/lixiang/Desktop/crash/4.0.1/QQStock.app

lideiMac:QQStock.app lixiang$ otool -arch arm64 -l ./QQStock | grep -B 1 -A 10 "LC_SEGM" | grep -B 3 -A 8 "__TEXT"

需要计算出绝对地址（基地址＋偏移地址）

QQStock                             0x0047e105 QQStock + 4219141
0x100406105 = 0x100000000 + 0x406105(4219141)
