UIWebView execCommand剪切,复制,粘贴

Question

我似乎无法将execCommand用于剪切,复制,粘贴以在contentEditable设置为true的UIWebView中工作.我可以使用selectAll命令选择文本,但剪切,复制和粘贴不起作用.

这是我正在使用的代码:

[webView stringByEvaluatingJavaScriptFromString:@"document.execCommand('cut', false, null)"];

还有什么我需要做的才能让剪贴板操作起作用吗？

Answer 1

按照之前的评论剪切,复制,粘贴命令似乎不起作用,所以我设法实现了相同的操作:

- (void)cut
{
    NSString *selection = [self.webView stringByEvaluatingJavaScriptFromString:@"window.getSelection().toString()"];
    [webView stringByEvaluatingJavaScriptFromString:@"document.execCommand('delete', false, null)"];
    [UIPasteboard generalPasteboard].string = selection;
}

- (void)paste
{
    NSString *text = [UIPasteboard generalPasteboard].string;
    [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.execCommand('insertHTML', false, '%@')", text]];
    [UIPasteboard generalPasteboard].string = @"";
}
