1.去除HTML标签
+ (NSString*)filterHTML:(NSString*)html
{
NSScanner* scanner = [NSScannerscannerWithString:html];
NSString* text =nil;
while([scannerisAtEnd]==NO)
{
//找到标签的起始位置
[scannerscanUpToString:@"<" intoString:nil];
//找到标签的结束位置
[scannerscanUpToString:@">"intoString:&text];
//替换字符
html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>",text] withString:@""];
}
return html;
}
2.标签语言转换富文本
+ (NSAttributedString*)HTMLStrToAttributedString:(NSString*)html;{
NSAttributedString * attrStr = [[NSAttributedString alloc] initWithData:[[NSString stringWithFormat:@"<span\">%@</span>",html] dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
return attrStr;
}
