Iphone 检索字符串时出现问题

我有一个数组，它有类似字符串的

"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>"

Thanx。为什么要使用那种格式的字符串？是否要从UIWebView中的JSON加载该返回字符串？如果是，那么您只需通过附加“使用此函数”调用loadHtmlString方法

NSString *str =@"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);

NSString*str=@“向左拐到加州视觉效果学院的Sri Krishna Nagar RdPass（左侧）\n”；
str=[str STRINGBYREPLACINGOCURNCESOFSTRING:@“\\r\\n”带字符串：@”“；
NSRange；
while（（r=[str rangeOfString:@“]+>”选项：NSRegularExpressionSearch]）。位置！=NSNotFound）
str=[str STRINGBYREPLAcingCharactersRange:r with string:@''；
NSLog（@“%@”，str）；

@Narayana..它解决了我的问题，但我不知道while循环能做什么..尤其是]+>。Thnx需要帮助

NSString *str =@"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);
