NSURL有特殊字符 [英] NSURL with special characters

问题描述

如何对此网址进行编码以显示在UIWebview中：

How can I encode this url to be displayed in a UIWebview:

http://de.wikipedia.org/?search=Bevölkerungsentwicklung

我试过：

-stringByAddingPercentEscapesUsingEncoding:NSUnicodeStringEncoding
-stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding

和

CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
                                        (CFStringRef)mobileUrl,
                                        NULL,
                                        (CFStringRef)@"!*'();:@&=+$,/?%#[]",
                                        kCFStringEncodingUTF8);

谢谢

推荐答案

只对URL字符串的搜索部分进行编码：

Encode just the search part of the URL string:

// searchString is the unescaped search string, e.g., "Bevölkerungsentwicklung"

NSString *encodedSearchString = [searchString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *urlString = [NSString stringWithFormat:@"http://de.wikipedia.org/?search=%@", encodedSearchString];
NSURL *url = [NSURL URLWithString:urlString];

（请注意，NSUTF8StringEncoding是使用的编码。）

(Note as well that NSUTF8StringEncoding is the encoding used.)
