/*

    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"];
