URL主机比较

Question

这里我试图比较2个url的主机。即使主机是相同的，它也不回应为什么!

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!");
    }

Answer 1

您需要使用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
