Question

在我的webview viewdidload中，我实现了以下代码。问题是当我包含NSString * encodedString时，webview不会出现。我有searchString空格，有时＆amp ;.关于这里发生了什么的任何想法？

NSString *urlString = [NSString stringWithFormat:@"http://google.com?q=%@", searchString];
        NSString * encodedString = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(
           NULL,(CFStringRef)urlString,
       NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]",
         kCFStringEncodingUTF8 ));

    NSLog(@"searchString is %@", searchString);
    NSURL *myURL =[NSURL URLWithString:encodedString];
    NSURLRequest *myRequest = [NSURLRequest requestWithURL:myURL];
    [searchWebView loadRequest:myRequest];

为此searchString生成google的第一页结果需要什么？

Answer 1

使用它来编码SearchString

SearchString=[[NSString stringWithFormat:@"%@", SearchString]  stringByAddingPercentEncodingWithAllowedCharacters:NSCharacterSet.URLQueryAllowedCharacterSet];

然后将其附加到您的网址

Answer 2

试试这个

NSString *urlString = [NSString stringWithFormat:@"http://www.google.com/search?q=%@",searchString];
   urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];


   NSURL *myURL =[NSURL URLWithString:urlString];
    NSURLRequest *myRequest = [NSURLRequest requestWithURL:myURL];
    [searchWebView loadRequest:myRequest];

webview不会加载字符串
