Javascript 无法在本地html文件中加载webview内部的google地图,javascript,html,ios,objective-c,google-maps-api-3,Javascript,Html,Ios,Objective C,Google Maps Api 3,我正在使用一个名为basicmap.html的本地html文件，其中包含 <!DOCTYPE html> <html> <head> </head> <body> <div id="map"></div> <script> function initMap() { // Create a m

我正在使用一个名为basicmap.html的本地html文件，其中包含

<!DOCTYPE html>
<html>
    <head>
    </head>
    <body>
        <div id="map"></div>
        <script>
            function initMap() {
                // Create a map object and specify the DOM element for display.
                var map = new google.maps.Map(document.getElementById('map'), {
                                              center: {lat: -34.397, lng: 150.644},
                                              scrollwheel: false,
                                              zoom: 8
                                              });
                                              console.log(map);
            }

            </script>
        <script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCvjeJZDdkpxCLasVMvTX2raxKkVGUULP8&callback=initMap"
            async defer></script>
    </body>
</html>

输出在webview中显示空白页。

在Info.plist中添加键和值

添加你的链接url，而不是google.com

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>New item</key>
            <string>http://www.google.com</string>
        </dict>
    </dict>

此处loadwebs是webview属性名称

请尝试以下代码

<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script type="text/javascript">
  function init() {
    var latlong = new google.maps.LatLng(23.0225, 72.5714);
    var myOptions = {
      zoom: 15,
      center: latlong,
      mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  }
</script>
</head>
<body onload="init()">
 <div id="map_canvas" style="width:100%; height:100%">
</body>
</html>

我还在info.plist文件中添加了NSAppTransportSecurity NSAllowsArbitraryLoads使用此方法-（void）loadHTMLString:（NSString*）string baseURL:（NSURL*）baseURL@Jigar我使用这个NSString htmlFile=[[NSBundle mainBundle]pathForResource:@“basic”类型：@“html”inDirectory:nil]；NSString htmlString=[NSString STRINGWITHCONTENTSOFILE:htmlFile编码：NSUTF8STRING编码错误：nil]；[\u webView加载htmlString:htmlString baseURL:[[NSBundle mainBundle]bundleURL]]；但这也不起作用/你检查你的html文件是否工作？@Jigar html页面在Safari中也显示为空白/Chrome@Sudipta查特吉，你检查我的答案了吗？

NSURLRequest* urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]];
[self.loadwebs loadRequest:urlRequest];

<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script type="text/javascript">
  function init() {
    var latlong = new google.maps.LatLng(23.0225, 72.5714);
    var myOptions = {
      zoom: 15,
      center: latlong,
      mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  }
</script>
</head>
<body onload="init()">
 <div id="map_canvas" style="width:100%; height:100%">
</body>
</html>

- (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL
