可以直接用的“ html转字符串string”方法

//html转字符串
-(NSString *)filterHTMLString:(NSString *)html

{

    NSScanner * scanner = [NSScanner scannerWithString:html];

    NSString * message = nil;

    while([scanner isAtEnd]==NO)

    {

        [scanner scanUpToString:@"<" intoString:nil];

        [scanner scanUpToString:@">" intoString:&message];

        html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>",message] withString:@""];
        html = [html stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@""];//去掉&nbsp

} return html; }
