URL主机比较 [英] URL host comparison

问题描述

在这里，我试图比较 2 个 URL 的主机.即使该主机是相同的，它也不会响应为什么！

Here I am trying to compare the hosts of 2 URLs. Even though that hosts are the same it does not respond why!

代码:

NSURL *url=[NSURL URLWithString:@"http://www.facebook.com/"?ref=logo" ];
    NSURL *domain=[ NSURL URLWithString:@"http://www.facebook.com" ];

    if ( [url host]==[domain host] ) {

        NSLog(@"hosts are matched");
    }else {
        NSLog(@"hosts are not matched!");
    }

推荐答案

你需要使用 isEqualToString:

NSURL *url=[NSURL URLWithString:@"http://www.facebook.com/?ref=logo" ];
NSURL *domain=[ NSURL URLWithString:@"http://www.facebook.com" ];

if ( [[url host] isEqualToString: [domain host]] ) {
    NSLog(@"hosts are matched");
}else {
    NSLog(@"hosts are not matched!");
}

结果

2011-11-23 11:55:06.182 TestApp[14404:207] hosts are matched
