UIWebView禁止复制实现方案

一、网上方案

- (void)webViewDidFinishLoad:(UIWebView*)theWebView

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

• 注释: 这个方案只能去除掉单页面应用, 既js里面没有打开两个页面.而且一些特殊的手势还是会触发弹框.

二、手势方案

- (void)webViewDidFinishLoad:(UIWebView*)theWebView

 for (UIView *subView in self.webView.scrollView.subviews) {
        for (UIGestureRecognizer *gesture in subView.gestureRecognizers) {
            gesture.delegate = self;
        }
    }

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]] || [gestureRecognizer isKindOfClass:NSClassFromString(@"UITapAndAHalfRecognizer")]) {
        return NO;
    }
    NSLog(@"gestureRecognizerShouldBegin == %@",NSStringFromClass([gestureRecognizer class]));
    return YES;
}

• 就是禁止掉UILongPressGestureRecognizer长按手势和UITapAndAHalfRecognizer系统的这个手势, 太坑了,测试半天才找到这个凶手
