GBPing |同步得到结果

Question

我正在使用GBPing来ping几个调用方法的IP。 问题是GBPing通过委托方法给出结果，我不知道如何监视来自另一个线程的委托结果。

示例代码，用于ping N个主机的循环。

for(int i=1; i< pow(2,(32-netmask)) -1; i++){
    ph[i] = [[PingHelper alloc] init];
    //compose IPv4
    NSString *finalAddr = [IPHelper composeIPv4:addrs[0] netmask:netmask host:i];
    [ph[i] ping:finalAddr semaphore:NULL];
}

PingHelper电话。

self->ping = [[GBPing alloc] init];
self->ping.host = host;
self->ping.delegate = self;
self->ping.timeout = 1.0;
self->ping.pingPeriod = 0.9;

[self->ping setupWithBlock:^(BOOL success, NSError *error) { //necessary to resolve hostname
    if (success) {
        //start pinging
        [self->ping startPinging];  
    }
    else {
        NSLog(@"failed to start");
    }
}];

//while(!finished);
return result;
