IOS开发之NSURL -电脑资料

    1:NSURL初始化方法:

NSURL*url=[NSURLURLWithString:@www.2cto.comid=1];

    2:解决NSURL初始化失败的相关解决方案.

    将传进来的NSString 进行 UTF8 转码即可.

    1:针对 URLWithString 初始化失败的解决方案

   

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

strLocalHtml=[NSStringstringWithFormat:@%@?Value=%@,strLocalHtml,self.txtUrl.text];

strLocalHtml=[strLocalHtmlstringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURL*url=[NSURLURLWithString:strLocalHtml];

    2:针对 fileURLWithPath 初始化失败的解决方案

   

self.filePathString=[self.filePathStringstringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURL*url=[NSURLfileURLWithPath:self.filePathString];

    转码成功后 会自动 在字符串左侧添加file:///

   

   

    3:NSURL 成功初始化后可以获取的参数 (摘自:NSURL 学习)

NSURL*url=[NSURLURLWithString:@www.2cto.com?tn=baiduhome_pg&bs=NSRUL&f=8&rsv_bp=1&rsv_spt=1&wd=NSurl&inputT=2709];

NSLog(@Scheme:%@,[urlscheme]);

NSLog(@Host:%@,[urlhost]);

NSLog(@Port:%@,[urlport]);

NSLog(@Path:%@,[urlpath]);

NSLog(@Relativepath:%@,[urlrelativePath]);

NSLog(@Pathcomponentsasarray:%@,[urlpathComponents]);

NSLog(@Parameterstring:%@,[urlparameterString]);

NSLog(@Query:%@,[urlquery]);

NSLog(@Fragment:%@,[urlfragment]);

NSLog(@User:%@,[urluser]);

NSLog(@Password:%@,[urlpassword]);

    结果如下:

2012-03-3118:22:20.917SmallDemoList[5473:11603]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:@simplewithExtension:@htmlsubdirectory:@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 Support/iPhone Simulator/5.1/Applications/FB0CDABC-D0E2-45FF-AA2C-959E8A65ADB4/SmallDemoList.app/KindEditor/examples/simple.html
