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
