禁用UIWebView的默认交互行为

        实现UIWebviewDelegate协议，在webViewDidFinishLoad:方法中添加如下代码 

1	- (void)webViewDidFinishLoad:(UIWebView *)webView {

2

// 禁用用户选择

3	[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.style.webkitUserSelect='none';"];

4

5	// 禁用长按弹出框

6	[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.style.webkitTouchCallout='none';"];

7

}
