"Turn left onto <b>Sri Krishna Nagar Rd</b><div class=\"google_note\">Pass by <b landmarkid=\"0x39ed58475c24020f:0x170a2130a5880d5a\" class=\"dir-landmark\">California Academy of Visual Effects</b> <div class=\"dirseg-sub\">(on the left)</div>\n</div>"

使用此

NSString *str [email protected]"Turn left onto <b>Sri Krishna Nagar Rd</b><div class=\"google_note\">Pass by <b landmarkid=\"0x39ed58475c24020f:0x170a2130a5880d5a\" class=\"dir-landmark\">California Academy of Visual Effects</b> <div class=\"dirseg-sub\">(on the left)</div>\n</div>"; 
    str = [str stringByReplacingOccurrencesOfString:@"\\r\\n" withString:@""]; 
    NSRange r; 
    while ((r = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound) 
    str = [str stringByReplacingCharactersInRange:r withString:@""]; 

    NSLog(@"%@",str);

@ Narayana..It已经解决了我的问题，但我不'不知道while循环做什么..尤其是<[^>] +>。Thnx的帮助 – iCoder4777

为什么你想要那种格式的字符串？你想从UIWebView中的JSON加载返回字符串吗？如果是的话，那么你可以简单地调用loadHtmlString方法通过将“< ”HTML> ..“ < ”/ HTML>“
