2 个解决方案

#1

you can disable the selection by using this code

您可以使用此代码禁用选择

[webView stringByEvaluatingJavaScriptFromString:@"document.body.style.webkitTouchCallout='none'; document.body.style.KhtmlUserSelect='none'"];

if you using Jscript in your web page then this could do the trick

如果你在你的网页中使用Jscript,那么这可以解决问题

[webView stringByEvaluatingJavaScriptFromString:@"window.getSelection().removeAllRanges();"];

if you want to disable copy paste then this could do the trick

如果你想禁用复制粘贴,那么这可以解决问题

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{    
    if (action == @selector(copy:) ||
        action == @selector(select:)||
        action == @selector(paste:)||
        action == @selector(cut:)) 
    {
        return NO;
    }
    return [super canPerformAction:action withSender:sender];
}

OR

 webView.userInteractionEnabled=NO; // in case you need to disable whole UIWebView

If you are using .css, you can add these to the appropriate style

如果您使用的是.css,则可以将它们添加到适当的样式中

    *.noselect {
            -webkit-user-select:none;
            -webkit-touch-callout:none;
    }
