/*

    關於UIPasteboard，若是直接使用pasteboard.string/ pasteboard.URL /pasteboard.image等，一次只能使用一個，且用系統的話，均可以被使用（- (void)setXXX:(id)data forPasteboardType:(NSString *)pasteboardType;）

    能夠避免全局被使用（須要typeName）；

    

    傳字典：須要歸檔

    NSDictionary *dic = @{@"name":@"哈哈碉堡啦",@"image":[UIImage imageNamed:@"qq"]};

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    NSData *dictData = [NSKeyedArchiver archivedDataWithRootObject:dic];

    [pasteboard setData:dictData forPasteboardType:@"AType"];

    

    接收：

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    NSDictionary *dict = [NSKeyedUnarchiver unarchiveObjectWithData:[pasteboard dataForPasteboardType:@"AType"]];

    NSString *name = [dict objectForKey:@"name"];
