去除NSString中的HTML标签

去掉NSString中的HTML标签

最近在用phonegap，经常出现字符串带有html标签。下面有个方法一步到位去掉HTML标签

+(NSString *)flattenHTML:(NSString *)html trimWhiteSpace:(BOOL)trim{    NSScanner *theScanner = [NSScanner scannerWithString:html];    NSString *text = nil;        while ([theScanner isAtEnd] == NO) {        // find start of tag        [theScanner scanUpToString:@"<" intoString:NULL] ;        // find end of tag        [theScanner scanUpToString:@">" intoString:&text] ;        // replace the found tag with a space        //(you can filter multi-spaces out later if you wish)        html = [html stringByReplacingOccurrencesOfString:                [ NSString stringWithFormat:@"%@>", text]                                               withString:@""];    }        return trim ? [html stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] : html;}

?调用方法：

? ??notification33.alertBody =[self flattenHTML:body trimWhiteSpace:YES];
