iOS：如何将HTML复制到剪切粘贴缓冲区？ [英] iOS: How to copy HTML into the cut-paste buffer?

问题描述

我有兴趣让我的用户将他们输入的文本复制到剪切和粘贴缓冲区，但我想将其作为HTML。

I'm interested in letting my users copy the text they've entered into the cut-and-paste buffer, but I'd like to do that as HTML.

这样的事情甚至可能吗？还是我需要使用MIME格式？ （我不知道。）

Is such a thing even possible? Or do I need to use a MIME format? (I have no idea.)

感谢。

推荐答案

下面的代码将把你的HTML从你的应用程序和苹果的邮件应用程序。这篇文档没有给你很多帮助，所以在一定程度上它是一个问题，苹果的应用程序停在板上，然后逆向工程。此解决方案采用早期的 stackoverflow post - 请点击此处的链接了解更多背景信息。 p>

The following code will get your HTML out of your app and into Apple's Mail app. The documentation doesn't give you a great deal of help on this, so in part it's a matter of looking at what Apple's apps park on the pasteboard and then reverse engineering that. This solution draws on an earlier stackoverflow post - follow up the links there for more background.

NSLog(@"Place HTML on the pasteboard");

UIPasteboard* pasteboard = [UIPasteboard generalPasteboard];
NSString *htmlType = @"Apple Web Archive pasteboard type";

// example html string
NSString* htmlString = @"<p style=\"color:gray\"> <a href=@\"http://itunes.apple.com/gb/app/paragraft/id412998778?mt=8\">Paragraft</a><br><em>Less than a word processor, more than plain text</em>";

NSMutableDictionary *resourceDictionary = [NSMutableDictionary dictionary];    

[resourceDictionary setObject:[htmlString dataUsingEncoding:NSUTF8StringEncoding]  forKey:@"WebResourceData"];

[resourceDictionary setObject:@"" forKey:@"WebResourceFrameName"];
[resourceDictionary setObject:@"text/html" forKey:@"WebResourceMIMEType"];
[resourceDictionary setObject:@"UTF-8" forKey:@"WebResourceTextEncodingName"];
[resourceDictionary setObject:@"about:blank" forKey:@"WebResourceURL"];

NSDictionary *containerDictionary = [NSDictionary dictionaryWithObjectsAndKeys:resourceDictionary, @"WebMainResource", nil];

NSDictionary *htmlItem = [NSDictionary dictionaryWithObjectsAndKeys:containerDictionary,htmlType,nil];

[pasteboard setItems: [NSArray arrayWithObjects: htmlItem, nil]];
