IOS去掉字符串中HTML标签的方法

 

 

后台返回的字符串中带HTML标签，如果不用webView加载解析的话，就直接去掉。

 

-(NSString *)filterHTML:(NSString *)html
{
    NSScanner * scanner = [NSScanner scannerWithString:html];
    NSString * text = nil;
    while([scanner isAtEnd]==NO)
    {
        //找到标签的起始位置
        [scanner scanUpToString:@"<" intoString:nil];
        //找到标签的结束位置
        [scanner scanUpToString:@">" intoString:&text];
        //替换字符
        html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>",text] withString:@""];
    }
    //    NSString * regEx = @"<([^>]*)>";
    //    html = [html stringByReplacingOccurrencesOfString:regEx withString:@""];
    return html;
}
