解析Objective-C中的NSURL

Question

我有一個可能有鏈接的NSTextView控件。我如何獲得鏈接的完整網址？

這裏是我迄今爲止

-(BOOL)textView:(NSTextView *)aTextView clickedOnLink:(id)aLink atIndex:(NSUInteger)charIndex 
{ 
    NSURL *htmlURL = [NSURL fileURLWithPathComponents:[aLink pathComponents]]; 
} 

這給了我與文件開頭的URL：//本地主機...我如何擺脫URL的那部分？

Answer 1

NSURL* url = [NSURL URLWithString:@"http://localhost/myweb/index.html"]; 
NSString* reducedUrl = [NSString stringWithFormat: 
    @"%@://%@", 
    url.scheme, 
    [url.pathComponents objectAtIndex:1]];
