Exception Types in iOS crash logs
问题 I've seen a few different types of crash logs since I begin learning iOS development. I know that: Exception Type: EXC_BAD_ACCESS (SIGSEGV) mean we are accessing a released object. but don't know about: Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Type: EXC_CRASH (SIGABRT) Exception Type: EXC_BREAKPOINT (SIGTRAP) Do you know how many Exception Types in iOS crash logs and what do they mean? 回答1: I know that: Exception Type: EXC_BAD_ACCESS (SIGSEGV) mean we are accessing a released object.
