    _webView.delegate=self;

    



//    NSString *filePath=[[NSBundle mainBundle] pathForResource:@"百度"ofType:@"html"];

    //禁用拖拽时的反弹效果

    _webView.scrollView.bounces=NO;

    //默认值为NO，用户不可以放大或缩小页面；如果设置为YES，页面可以通过放大缩小去适应，用户也可以通过手势来放大和缩小

    _webView.scalesPageToFit=YES;

    //此属性可以设定使电话号码、网址、电子邮件和符合格式的日期等文字变为链接文字

//    typedef NS_OPTIONS(NSUInteger, UIDataDetectorTypes) {

//        UIDataDetectorTypePhoneNumber   = 1 << 0,          // Phone number detection 识别电话号码

//        UIDataDetectorTypeLink          = 1 << 1,          // URL detection识别网址，链接等

//        UIDataDetectorTypeAddress       = 1 << 2,          // Street address detection 识别地址

//        UIDataDetectorTypeCalendarEvent = 1 << 3,          // Event detection 识别时间

//        UIDataDetectorTypeNone          = 0,               // No detection at all 全都不识别

//        UIDataDetectorTypeAll           = NSUIntegerMax    // All types 全部识别

//    };

    _webView.dataDetectorTypes=UIDataDetectorTypePhoneNumber;

    

//    控制webview使用html5的video播放视频不全屏(inline)的方法

//    webview中用html5的video方式播放视频时，在ipad上是默认原来大小的，而在iphone上是默认全屏播放的

//    HTML里video必须加上webkit-playsinline属性

//    <video id="player" width="480" height="320" webkit-playsinline>

//    Obj-C里，webview设置allowsInlineMediaPlayback属性为YES

//    webview.allowsInlineMediaPlayback = YES;

    _webView.allowsInlineMediaPlayback=YES;

    

    //是否支持自动播放

//    <script>

//    if ("wView" in window) {

//        window.wView.allowsInlineMediaPlayback = "YES";

//        window.wView.mediaPlaybackRequiresUserAction = "NO";

//    }

//    </script>

//    在head中加入此段代码，ios音视频不能自动播放的问题迎刃而解。

//    当然，在video标签中，需要先设定autoplay和preload属性，如下：

//    <video src="xxxxxx" autoplay preload></video>

    

    _webView.mediaPlaybackRequiresUserAction=NO;

    

    //从这个页面是否可以Air Play。 在iPhone和iPad上默认使YES。

    _webView.mediaPlaybackAllowsAirPlay=YES;

    

    //是否网页内容下载完毕才开始渲染web视图，默认为NO

    _webView.suppressesIncrementalRendering=NO;

    

    //是否在web页面响应用户输入弹出键盘，默认为YES

    _webView.keyboardDisplayRequiresUserAction=YES;

    

    //IOS7增加了分页功能

//    @property (nonatomic) UIWebPaginationMode paginationMode NS_AVAILABLE_IOS(7_0);

//    @property (nonatomic) UIWebPaginationBreakingMode paginationBreakingMode NS_AVAILABLE_IOS(7_0);

//    @property (nonatomic) CGFloat pageLength NS_AVAILABLE_IOS(7_0);

//    @property (nonatomic) CGFloat gapBetweenPages NS_AVAILABLE_IOS(7_0);

//    @property (nonatomic, readonly) NSUInteger pageCount NS_AVAILABLE_IOS(7_0);

    _activityView.activityIndicatorViewStyle=UIActivityIndicatorViewStyleWhiteLarge;

    [self.view addSubview:_activityView];

与JS交互这块由于没找到好的系统的教程，暂缺
