[英]Disable copy and paste in UIWebView
问题描述
Nearly, I had tried every thing to disable copy/paste in UIWebView but nothing worked with me. 
差不多，我曾经尝试过在UIWebView禁用复制/粘贴的所有东西，但没有任何方法可以解决这个问题。
I'm loading my UIWebView from a string (array of strings) as follows: 我正在从字符串（字符串数组）加载我的UIWebView ，如下所示：
[webView loadHTMLString:
[NSString stringWithFormat:@"%@<p class=\"paragraph\" style=\"float: right\" >%@</p>",css,[[array objectAtIndex:0] valueForKey:@"content"]] baseURL:nil ];
I had tried this: 我试过这个：
-(void)webViewDidFinishLoad:(UIWebView *)webView1{
[webView1 stringByEvaluatingJavaScriptFromString:@"document.body.style.webkitUserSelect='none';"];
}
and this: 和这个：
NSString *css =
@"<head><style><body> *{-webkit-touch-callout: none; -webkit-user-select: none;}</style> </head> </body> ";
but nothing worked with me especially for iOS 4.2 但是没有任何关系，特别是对于iOS 4.2

It seems it is more complex that that... have a look at this thread on SO which details all you have to do... 似乎更复杂的是......看看SO上的这个帖子 ，详细说明你要做的一切......
summary: you need to: 总结：你需要：
modify your CSS (like you do): 修改你的CSS（就像你一样）：
<style type="text/css">
* {
-webkit-touch-callout: none;
-webkit-user-select: none; /* Disable selection/Copy of UIWebView */
}
</style>
adding some javascript: 添加一些JavaScript：
NSString * jsCallBack = @"window.getSelection().removeAllRanges();";
[webView stringByEvaluatingJavaScriptFromString:jsCallBack];
disable the copy/paste menu: 禁用复制/粘贴菜单：
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
BOOL superCanPerform = [super canPerformAction:action withSender:sender];
if (superCanPerform) {
if (action == @selector(copy:) ||
action == @selector(paste:)||
action == @selector(cut:))
{
return _copyCutAndPasteEnabled;
}
}
return superCanPerform;
}
canPerformAction should be defined in your UIWebView; canPerformAction应该在你的UIWebView中定义; you have two options for that: 你有两个选择：
defining a category for UIWebView (if it's ok to remove this behaviour from all of your UIWebViews);
为UIWebView定义一个类别（如果可以从所有UIWebView中删除此行为）; derive your own web view class from
UIWebViewand override that method in there.从UIWebView派生自己的Web视图类并在那里覆盖该方法。

-webkit-user-select: none; /* Disable selection/Copy of UIWebView */
还将禁用Mobile Safari上的表单。

Use this. 用这个。
<style type="text/css">
*:not(input):not(textarea) {
-webkit-user-select: none; /* disable selection/Copy of UIWebView */
-webkit-touch-callout: none; /* disable the IOS popup when long-press on a link */
}
</style>
If you want Disable only anchor button tag use this.
a {-webkit-user-select: none; /* disable selection/Copy of UIWebView */
-webkit-touch-callout: none; /* disable the IOS popup when long-press on a link */
}
