ios - 如何以编程方式从 iPhone 获取 iPhone 应用程序崩溃日志文件

有没有办法通过编程方式访问 iphone 崩溃日志文件。我试图编写一个崩溃报告功能，当您在崩溃后启动应用程序时，它会提供将崩溃报告发送到服务器。我找不到如何在应用程序中获取崩溃日志。

您可以使用以下逻辑。

aslmsg q, m;
int i;
const char *key, *val;
float how_old = fTime ;
q = asl_new(ASL_TYPE_QUERY);
asl_set_query(q, ASL_KEY_LEVEL, strLoggerLevel ,ASL_QUERY_OP_LESS_EQUAL);
asl_set_query(q, ASL_KEY_FACILITY, [@"YourBundleIdOfAPP" UTF8String] ,ASL_QUERY_OP_EQUAL);

asl_set_query(q, ASL_KEY_TIME, [[NSString stringWithFormat"%.f", [[NSDate date] timeIntervalSince1970] - how_old] UTF8String], ASL_QUERY_OP_GREATER_EQUAL);
int goInside=0;
aslresponse r = asl_search(NULL, q);
while (NULL != (m = aslresponse_next(r)))
{
    NSString *cValueToWrite;
    NSMutableDictionary *tmpDict = [NSMutableDictionary dictionary];

    for (i = 0; (NULL != (key = asl_key(m, i))); i++)
    {
        //get the only required fields
        if(i==12 || i==10 || i==11 || i==8 || i==9 ||i==3)
        {
            NSString *keyString = [NSString stringWithUTF8Stringchar *)key];
            val = asl_get(m, key);

            NSString *string = [NSString stringWithUTF8String:val];
            [tmpDict setObject:string forKey:keyString];
        }
    }

    cValueToWrite=[[NSString alloc]initWithFormat"\n--------------[Debug]----------------\nDateTime: %@\nApplication: %@\nInfo: %@",[tmpDict valueForKey"CFLog Local Time"],[tmpDict valueForKey"Sender"],[tmpDict valueForKey"Message"]];
}

strLoggerLevel 是 NSString，它包含您想要的记录器类型，范围高达 7。
