1:NSURL初始化方法:
NSURL *url=[NSURL URLWithString:@"http://www.baidu.com?id=1"];
2:解決NSURL初始化失敗的相關(guān)解決方案.
將傳進(jìn)來(lái)的NSString 進(jìn)行 UTF8 轉(zhuǎn)碼即可.
1:針對(duì) URLWithString 初始化失敗的解決方案
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];
2:針對(duì) fileURLWithPath 初始化失敗的解決方案
NSURL *url = [NSURL fileURLWithPath:self.filePathString];
轉(zhuǎn)碼成功后 會(huì)自動(dòng) 在字符串左側(cè)添加 "file:///"
3:NSURL 成功初始化后可以獲取的參數(shù)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]);
NSLog(@"Host: %@", [url host]);
NSLog(@"Port: %@", [url port]);
NSLog(@"Path: %@", [url path]);
NSLog(@"Relative path: %@", [url relativePath]);
NSLog(@"Path components as array: %@", [url pathComponents]);
NSLog(@"Parameter string: %@", [url parameterString]);
NSLog(@"Query: %@", [url query]);
NSLog(@"Fragment: %@", [url fragment]);
NSLog(@"User: %@", [url user]);
NSLog(@"Password: %@", [url password]);
結(jié)果如下:

4:根據(jù)文件名稱和文件后綴獲取程序包內(nèi)容文件的路徑
NSURL *urlKindEditor = [[NSBundlemainBundle]URLForResource:@"simple"withExtension:@"html"subdirectory:@"KindEditor/examples"];
URLForResource:文件名稱
withExtension:文件后綴
subdirectory:在程序包中的哪個(gè)子目錄中尋找.
如果沒有找到將會(huì)返回nil
找到后返回如下路徑: file://localhost/Users/amarishuyi/Library/Application%20Support/iPhone%20Simulator/5.1/Applications/FB0CDABC-D0E2-45FF-AA2C-959E8A65ADB4/SmallDemoList.app/KindEditor/examples/simple.html
5:對(duì)比兩個(gè)URL 是否相等
[url isEqual:[_audioPlayer url]]
