/*
關於UIPasteboard，如果直接使用pasteboard.string/ pasteboard.URL /pasteboard.image等，一次只能使用一個，且用系統的話，都可以被使用（- (void)setXXX:(id)data forPasteboardType:(NSString *)pasteboardType;）
可以避免全域性被使用（需要typeName）；
傳字典：需要歸檔
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"];
