/* 关于UIPasteboard，如果直接使用pasteboard.string/ pasteboard.URL /pasteboard.image等，一次只能使用一个，且用系统的话，都可以被使用（- (void)setXXX:(id)data forPasteboardType:(NSString *)pasteboardType;） 可以避免全局被使用（需要typeName）；
传字典：需要归档 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"]; */
