Question

我在我的iOS应用程序中设置了uncaughtExceptionHandler，并从用户那里获得了以下数据，但我不知道如何解释它们以找到错误的位置。加号背后的数字是多少？我如何使用地址来获取错误的位置？

callStackReturnAddresses

(0x305b1f53 0x3ac1a6af 0x304e85f3 0xe7cd5 0x32d3d419 0x32eb3e0b 0x32dd1a83 0x32dd188d 0x32dd1825 0x32d23023 0x329ac24b 0x329a7a5b 0x329a78ed 0x329a72ff 0x329a710f 0x329a0e3d 0x3057d1d5 0x3057ab79 0x3057aebb 0x304e5ce7 0x304e5acb 0x351b3283 0x32d87a41 0xb51d7 0xb5198)

符号在设备端可用不可靠，在iOS 6及更高版本中，许多系统符号只是<redacted>。
