UIWebView 设置

UIWebView背景透明且无拖拽后的上下阴影
1.首先UIWebView背景透明


    // set background transparent, also can set it in nib file
    webView_.backgroundColor = [UIColor clearColor];
    webView_.opaque = NO;
2.隐藏拖拽webview时上下的两个有阴影效果的subview


    // remove shadow view when drag web view
    for (UIView *subView in [webView_ subviews]) {
        if ([subView isKindOfClass:[UIScrollView class]]) {
            for (UIView *shadowView in [subView subviews]) {
                if ([shadowView isKindOfClass:[UIImageView class]]) {
                    shadowView.hidden = YES;
                }
            }
        }
    }
其他
a.UIWebView加载本地html


    // get html file path
    NSString *path = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"html"];
    [webView_ loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:path]]];
b.禁用UIWebView拖拽时的反弹效果


    // disable view bounce
    [(UIScrollView *)[[webView_ subviews] objectAtIndex:0] setBounces:NO];
c.禁用UIWebView拖拽


    // disable touch move
    <script type="text/javascript">
        document.ontouchmove = function(e) {
            e.preventDefault();
        }
    </script>
