iOS开发——崩溃日志收集

void registerSignalHandler(void) {
    NSSetUncaughtExceptionHandler (&chUncaughtExceptionHandler);
    signal(SIGSEGV, handleSignalException);
    signal(SIGFPE, handleSignalException);
    signal(SIGBUS, handleSignalException);
    signal(SIGPIPE, handleSignalException);
    signal(SIGHUP, handleSignalException);
    signal(SIGINT, handleSignalException);
    signal(SIGQUIT, handleSignalException);

    signal(SIGILL, handleSignalException);
}

void handleSignalException(int signal) {
    NSMutableString *crashString = [[NSMutableString alloc]init];
    void* callstack[128];
    int i, frames = backtrace(callstack, 128);
    char** traceChar = backtrace_symbols(callstack, frames);
    for (i = 0; i <frames; ++i) {
        [crashString appendFormat:@"%s

}

void chUncaughtExceptionHandler(NSException *exception) {
    // 异常的堆栈信息
    NSArray *stackArray = [exception callStackSymbols];

    // 出现异常的原因
    NSString *reason = [exception reason];

    // 异常名称
    NSString *name = [exception name];
    
    NSString *exceptionInfo = [NSString stringWithFormat:@"Exception reason：%@
Exception name：%@
Exception stack：%@", name, reason, stackArray];
    NSLog(@"exception===%@",exceptionInfo);
    //这里先保存在本地，在下次打开时再上传服务器
}

在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 里面直接调用：registerSignalHandler();
