Battle: Item usage

Items can be used during battle, but you cannot change equipment. I'm having problem using up the turn when the player uses the item. It sounds like a simple thing! UIAlertView is so handy. I wish I could customize the design though.
戦闘中のアイテムの使用はできるようになったけど、ターン終了がうまくいかない。UIAlertViewは使えるがデザインをカスタマイズできないのが残念。

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"This is UIAlertView" delegate:nil cancelButtonTitle:@"OKotherButtonTitles:nil];
[alert show];
[alert release];
