    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;)

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

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

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