检测NSTextField上的粘贴 [英] Detect paste on NSTextField

问题描述

我正在尝试对NSTextField进行粘贴操作.

I'm trying to handle a paste operation on a NSTextField.

我找到了类似文章，但对于NSTextView.我通过覆盖NSTextField并放置了以下代码来尝试与此类似的代码:

I found a similar article but for NSTextView. I tried code similar to this by overriding NSTextField and putting:

- (BOOL)readSelectionFromPasteboard:(NSPasteboard *)pboard
{
    return [super readSelectionFromPasteboard: pboard];
}

但是这种方法似乎永远不会被调用.

But this method seems to never be called.

关于如何在NSTextField上检测过去的任何建议?

Any suggestions on how to detect a past on NSTextField?

推荐答案

您可以使用NSTextFieldDelegate委托方法- (BOOL) control:(NSControl*) control textView:(NSTextView*) textView doCommandBySelector:(SEL) commandSelector并注意paste:选择器.

You could use the NSTextFieldDelegate delegate method - (BOOL) control:(NSControl*) control textView:(NSTextView*) textView doCommandBySelector:(SEL) commandSelector and watch for the paste: selector.
