iOSRoutingTable

获取iOS手机路由表

看到surge app里提供了路由表信息，感觉在调试网络时候非常有用。

`

__block NSString *showStr = @"Destination        Gateway            Flags        Refs      Use   Netif Expire    \r\n";

NSArray<RoutingTableItem *> *result = [Router getRoutingTable];

[result enumerateObjectsUsingBlock:^(RoutingTableItem *obj, NSUInteger idx, BOOL * _Nonnull stop) {
    NSString *dest = [[NSString stringWithFormat:@"%@", obj.destination] stringByPaddingToLength:19 withString:@" " startingAtIndex:0];
    NSString *gateway = [[NSString stringWithFormat:@"%@", obj.gateway] stringByPaddingToLength:19 withString:@" " startingAtIndex:0];
    NSString *flags = [[NSString stringWithFormat:@"%@", obj.flags] stringByPaddingToLength:13 withString:@" " startingAtIndex:0];
    NSString *refs = [[NSString stringWithFormat:@"%@", obj.refs] stringByPaddingToLength:10 withString:@" " startingAtIndex:0];
    NSString *use = [[NSString stringWithFormat:@"%@", obj.use] stringByPaddingToLength:6 withString:@" " startingAtIndex:0];
    NSString *netif = [[NSString stringWithFormat:@"%@", obj.netif] stringByPaddingToLength:6 withString:@" " startingAtIndex:0];
    
    NSString *expire = [[NSString stringWithFormat:@"%@", obj.expire] stringByPaddingToLength:10 withString:@" " startingAtIndex:0];
    
    NSString *itemstr = [NSString stringWithFormat:@"%@%@%@%@%@%@%@\r\n",dest,gateway,flags,refs,use,netif,expire];
    showStr = [showStr stringByAppendingString:itemstr];
}];

self->txtView.text = showStr;

TODO:

flags 可能不全，已尽最大努力找了linux相关netstat的资料了。
