How to copy textField to OSX clipboard?
提问by 0SX
I'm stuck here. I know how to copy and paste on the iPhone side of things but how can I copy contents from a textField to the global clipboard in OSX. I've been searching the web but there are really no examples. So let me explain in detail what I'm trying to accomplish. I have a NSTextField named helloField and I want to be able to copy the contents of this helloField to the global pasteboard by pressing a button. How can this be done and is there certain libraries I need? Thanks.
我被困在这里。我知道如何在 iPhone 端复制和粘贴东西，但如何将内容从 textField 复制到 OSX 中的全局剪贴板。我一直在网上搜索，但真的没有例子。所以让我详细解释一下我要完成的任务。我有一个名为 helloField 的 NSTextField，我希望能够通过按下按钮将这个 helloField 的内容复制到全局粘贴板。如何做到这一点，我需要某些库吗？谢谢。

Code to copy a string to the clipboard:
将字符串复制到剪贴板的代码：
[[NSPasteboard generalPasteboard] clearContents];
[[NSPasteboard generalPasteboard] setString:copiedString forType:NSPasteboardTypeString];
NSStringPboardTypeis deprecated. There's a note in NSPasteboard.habout pboardtypes:
NSStringPboardType已弃用。NSPasteboard.h关于pboard类型有一个注释：
Use of pboard types should be replaced with use of UTIs. Pboard types will be deprecated in a future release.
应使用 UTI 代替使用 pboard 类型。Pboard 类型将在未来版本中弃用。
Also in the header file:
同样在头文件中：
APPKIT_EXTERN NSString *const NSPasteboardTypeString NS_AVAILABLE_MAC(10_6); // Replaces NSStringPboardType
...
APPKIT_EXTERN NSString *NSStringPboardType; //Use NSPasteboardTypeString
APPKIT_EXTERN NSString *const NSPasteboardTypeString NS_AVAILABLE_MAC(10_6); // 替换 NSStringPboardType
...
APPKIT_EXTERN NSString *NSStringPboardType; //使用 NSPasteboardTypeString

For Cocoa macOS in Swift 3:
对于 Swift 3 中的 Cocoa macOS：
let pasteBoard = NSPasteboard.general()
pasteBoard.clearContents()
pasteBoard.setString("something", forType: NSPasteboardTypeString)
