我想检查是否可以访问本地LAN上的Web服务器。我查看了Apple的Rechability Sample,但是这个示例表明所有本地的局域网都可以访问。
任何想法如何检查?
感谢的

我为此做了一个解决方法:
- (BOOL *) getOnlineState {
BOOL *onlineState;
NSURL *serverURL = [NSURL URLWithString:@"http://192.168.0.10:80/index.html"];
NSURLRequest *request = [NSURLRequest requestWithURL:serverURL];
NSURLResponse *response;
NSError *error;
NSData *receivedData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (receivedData == nil)
onlineState = (BOOL *)NO;
else
onlineState = (BOOL *)YES;
return onlineState;
}
