NSURL中url的组成

原文:blog.csdn.net/zhiyou007/article/details/8257942

1:NSURL初始化方法:

NSURL *url=[NSURL URLWithString:@"http://www.baidu.com?id=1"];

2:解决NSURL初始化失败的方法.

将传进来的NSString 进行 UTF8 转码即可.

NSString *strLocalHtml = @"file:///Users/amarishuyi/Desktop/My IPhone Life/WebDeveloper/WebPlug-in/ExtEditor/DataPage/KMQT/Ext-HTMLEditor.html";

strLocalHtml = [NSString stringWithFormat:@"%@?Value=%@",strLocalHtml,self.txtUrl.text];

strLocalHtml= [strLocalHtml stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURL * url=[NSURL URLWithString:strLocalHtml];

3:NSURL 成功初始化后可以获取的参数 

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"];

NSLog(@"Scheme: %@", [url scheme]);  结果:Scheme: http

NSLog(@"Host: %@", [url host]);  结果:Host: www.baidu.com

NSLog(@"Port: %@", [url port]);  结果:Port: (null)

NSLog(@"Path: %@", [url path]); 结果:Path: /s

NSLog(@"Relative path: %@", [url relativePath]);结果:Relative path: /s

NSLog(@"Path components as array: %@", [url pathComponents]);结果:Path componentsasarray: (

"/",

s

)

NSLog(@"Parameter string: %@", [url parameterString]);结果:Parameterstring: (null)

NSLog(@"Query: %@", [url query]);结果:Query: tn=baiduhome_pg&bs=NSRUL&f=8&rsv_bp=1&rsv_spt=1&wd=NSurl&inputT=2709

NSLog(@"Fragment: %@", [url fragment]);结果:Fragment: (null)

NSLog(@"User: %@", [url user]);结果:User: (null)

NSLog(@"Password: %@", [url password]);结果:Password: (null)

4:根据文件名称和文件后缀获取程序包内容文件的路径

NSURL*urlKindEditor = [[NSBundlemainBundle]URLForResource:@"simple"withExtension:@"html"subdirectory:@"KindEditor/examples"];

URLForResource:文件名称

withExtension:文件后缀

subdirectory:在程序包中的哪个子目录中寻找.

如果没有找到将会返回nil

找到后返回如下路径:file://localhost/Users/amarishuyi/Library/Application%20Support/iPhone%20Simulator/5.1/Applications/FB0CDABC-D0E2-45FF-AA2C-959E8A65ADB4/SmallDemoList.app/KindEditor/examples/simple.htmlblog.c
