带有中文的url和NSString中文的转换

NSString *url = @"http://tw.news.yahoo.com/麵包魂東京吸睛-粉絲包圍導演-061222049.html"; NSLog(@"url: %@", url);
//ios9中采用下边方法转换

NSString *urlString = [url stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];

 //之前方法 NSString *urlString = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"encode url: %@", encodeUrl); NSString *decodeUrl = [encodeUrl stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"decode url: %@", decodeUrl); 結果如下： url: http://tw.news.yahoo.com/麵包魂東京吸睛-粉絲包圍導演-061222049.html encode url: http://tw.news.yahoo.com/%E9%BA%B5%E5%8C%85%E9%AD%82%E6%9D%B1%E4%BA%AC%E5%90%B8%E7%9D%9B-%E7%B2%89%E7%B5%B2%E5%8C%85%E5%9C%8D%E5%B0%8E%E6%BC%94-061222049.html decode url: http://tw.news.yahoo.com/麵包魂東京吸睛-粉絲包圍導演-061222049.html
