Writing a string to NSPasteBoard

Swift 2:

Copy a string to the general pasteboard with Swift 2:

let pasteboard = NSPasteboard.generalPasteboard()
pasteboard.declareTypes([NSPasteboardTypeString], owner: nil)
pasteboard.setString("Hello", forType: NSPasteboardTypeString)

Here is the working version of the method:

- (BOOL) writeToPasteBoard:(NSString *)stringToWrite
{
    [pasteBoard declareTypes:[NSArray arrayWithObject:NSStringPboardType] owner:nil];
    return [pasteBoard setString:stringToWrite forType:NSStringPboardType];
}

Before you copy a string on NSPasteboard it's better to clear the contents and then save.

Swift 4

    // Set string
    NSPasteboard.general.clearContents()
    NSPasteboard.general.setString("I copied a string", forType: .string)
    // Read copied string
    NSPasteboard.general.string(forType: .string)

Objective-C

    // Set string
    [[NSPasteboard generalPasteboard] clearContents];
    [[NSPasteboard generalPasteboard] setString:@"I copied a string" forType:NSPasteboardTypeString];
    // Read string
    [[NSPasteboard generalPasteboard] stringForType:NSPasteboardTypeString];

And also there are other available types for copying items on NSPasteboard. Like:

  • NSPasteboardTypeString
  • NSPasteboardTypePDF
  • NSPasteboardTypeTIFF
  • NSPasteboardTypePNG
  • NSPasteboardTypeRTF
