iphone - 带有特殊字符的NSURL

如何编码此URL以显示在UIWebview中:

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

我试过了:

-stringByAddingPercentEscapesUsingEncoding:NSUnicodeStringEncoding
-stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding

和

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

谢谢

最佳答案

仅对URL字符串的搜索部分进行编码:

// 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];

(还要注意，NSUTF8StringEncoding是使用的编码。)
