使用NSHost访问IP地址 [英] Accessing IP Address with NSHost

问题描述

我想使用 NSHost 获取IP地址。使用 NSHost 对象，我可以使用地址方法访问对象数组，其中之一是IP地址。我担心，虽然IP地址可能改变阵列中的位置从一台机器到另一台。有没有办法以普遍的方式访问这些信息？

I am trying to get the IP Address using NSHost. With the NSHost object I can use the addresses method to access an array of objects one of which is the IP Address. I fear though that the IP Address may change position in the array from one machine to the other. Is there a way to access this information in a universal way?

有人尝试在上一篇文章中回答这个问题，但是你可以看到它的缺点。

There was an attempt to answer this question in a previous post, but as you can see it falls short.

IP地址？ - Cocoa

这是我的代码：

+(NSString *) ipAddress {
    NSHost * h = [[[NSHost currentHost] addresses] objectAtIndex:1];
    return h ;  
}

推荐答案

机器没有问题。

 -(void) getIPWithNSHost{
    NSArray *addresses = [[NSHost currentHost] addresses];

for (NSString *anAddress in addresses) {
    if (![anAddress hasPrefix:@"127"] && [[anAddress componentsSeparatedByString:@"."] count] == 4) {
         stringAddress = anAddress;
        break;
    } else {
        stringAddress = @"IPv4 address not available" ;
    }
}
        //NSLog (@"getIPWithNSHost: stringAddress = %@ ",stringAddress);    

}

NSString * stringAddress;被声明为else

NSString *stringAddress; is declared else where
