NSURL其实就是我们在浏览器上看到的网站地址，这不就是一个字符串么，为什么还要在写一个NSURL呢，主要是因为网站地址的字符串都比较复杂，包括很多请求参数，这样在请求过程中需要解析出来每个部门，所以封装一个NSURL，操作很方便：

**\[cpp\]** [view plain][] [copy][view plain]

1.  NSURL \*url = \[NSURL URLWithString:@"http://www.baidu.com/s?tn=baiduhome\_pg&bs=NSRUL&f=8&rsv\_bp=1&rsv\_spt=1&wd=NSurl&inputT=2709"\]; 
2.  
3.   NSLog(@"Scheme: %@", \[url scheme\]); 
4.  
5.   NSLog(@"Host: %@", \[url host\]); 
6.  
7.   NSLog(@"Port: %@", \[url port\]); 
8.  
9.   NSLog(@"Path: %@", \[url path\]); 
10. 
11.  NSLog(@"Relative path: %@", \[url relativePath\]); 
12. 
13.  NSLog(@"Path components as array: %@", \[url pathComponents\]); 
14. 
15.  NSLog(@"Parameter string: %@", \[url parameterString\]); 
16. 
17.  NSLog(@"Query: %@", \[url query\]); 
18. 
19.  NSLog(@"Fragment: %@", \[url fragment\]); 
20. 
21.  NSLog(@"User: %@", \[url user\]); 
22. 
23.  NSLog(@"Password: %@", \[url password\]);

结果：

**\[cpp\]** [view plain][] [copy][view plain]

1.  2012-08-29 15:52:23.781 NSurl\[3560:f803\] Scheme: http
