我怎麼能在日誌文件中搜索在IOS與ASL另一個PID

Question

我有這個梅索德：

q = asl_new(ASL_TYPE_QUERY); 
asl_set_query(q, ASL_KEY_SENDER, "MyApp", ASL_QUERY_OP_EQUAL); 

// Count the number of results 
r = asl_search(NULL, q); 
while (NULL != (m = aslresponse_next(r))) { 
    counter++; 
} 

r = asl_search(NULL, q); 
while (line++ < counter && NULL != (m = aslresponse_next(r))) 
{ 
    // Take only the latest results 
    if (!(line < counter-NUMBER_OF_LOG_MESSAGES)) { 
     log = [NSMutableDictionary dictionary]; 
     for (i = 0; (NULL != (key = asl_key(m, i))); i++) 
     { 
      keyString = [NSString stringWithUTF8String:(char *)key]; 

      if ([self.logKeyFilter containsObject:keyString]) { 
       val = asl_get(m, key); 

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

     date = [dateFormat stringFromDate:[NSDate dateWithTimeIntervalSince1970:[[log objectForKey:@"Time"] doubleValue]]]; 
     [logs addObject:[NSString stringWithFormat:@"%@ %@ %@", date, [self.logLevelKeyFilter objectForKey:[log objectForKey:@"Level"]], [log objectForKey:@"Message"]]]; 
    } 
} 
aslresponse_free(r); 
return logs; 

其返回最新日誌「MyApp的」。 NUMBER_OF_LOG_MESSAGES這裏只是取最新的日誌。

問題是，當我有MyApp的崩潰與PID X和我重新啓動MyApp的漁獲日誌，我只有日誌我的新PID Y.

所以，我怎麼能在每一個日誌搜索文件來查找MyApp的日誌。

謝謝。

的問題是一樣的這個鏈接： Logs that are visible on iOS5 are not visible on iOS 6 (only on device)

按照它的答案。
