如何将最好的字符串或数字数组发送到粘贴板？

我尝试过使用[pasteBoard writeObjects：]，但看起来我必须继承NSArray才能做到这一点，它会要求一个协议。

也许存档和取消归档或其他想法？谢谢，何。

Answer 1

首先将数组转换为字符串接下来将其写入粘贴板。

NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"First Line",@"Second Line",nil];
NSPasteboard * pasteBoard = [NSPasteboard generalPasteboard];
NSString * string = [array componentsJoinedByString: @"\n"];
[pasteBoard declareTypes:[NSArray arrayWithObject:NSStringPboardType] owner:nil];
[pasteBoard setString:string forType:NSStringPboardType];

您可以向NSString添加类别以向粘贴板添加字符串：

@implementation NSString (PasteboardGoodies)
- (void) sendToPasteboard
{
        [[NSPasteboard generalPasteboard] 
            declareTypes: [NSArray arrayWithObject: NSStringPboardType]
            owner:nil];
        [[NSPasteboard generalPasteboard]
            setString: self
            forType: NSStringPboardType];
} // sendToPasteboard

@end // PasteboardGoodies

将字符串数组发送到NSPasteBoard
