Question

我要问一个简单而基本的问题，不要因此而杀了我。

我想将HTML字符串解码为普通字符串。

我试过了：

 NSString*  testString =[htmlString  stringByConvertingHTMLToPlainText];
 - (NSString *)stringByStrippingTags;
 - (NSString *)stringWithNewLinesAsBRs;
 - (NSString *)stringByRemovingNewLinesAndWhitespace;
 - (NSString *)stringByDecodingHTMLEntities;
 - (NSString *)stringByEncodingHTMLEntities;

但这些都不在现在。所以帮我删除＆＃34; '＆＃34;和＆＃34; ＆amp;＃8211＆＃34;等，并将html转换为普通字符串。

试试这段代码..

（NSString *）stringByStrippingHTML：（NSString *）inputString { NSMutableString * outString;

if（inputString） { if（[inputString length]＆gt; 0） { NSRange r;

    inputString = [inputString stringByReplacingOccurrencesOfString:@"</div>" withString:@"\n\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"</DIV>" withString:@"\n\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<br/>" withString:@"\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<br />" withString:@"\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<br>" withString:@"\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<BR>" withString:@"\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<BR />" withString:@"\n"];
    inputString = [inputString stringByReplacingOccurrencesOfString:@"<BR/>" withString:@"\n"];

    outString = [[NSMutableString alloc] initWithString:inputString];
    while ((r = [outString rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
    {
        [outString deleteCharactersInRange:r];
    }
    NSString *finalString = outString;
    finalString =[finalString stringByDecodingHTMLEntities];
    return finalString;
}

} return outString; }

如何在iOS中将html字符串转换为普通字符串？
