I suspect in the method you listed. If you want the alert after the deletion, then try placing it at the end. If you want to warn of a deletion, I have to wonder why you think the user didn't mean the action they just took. Still, I think you'd save all of the passed parameters, set a flag that you're waiting for a response, post the alert and skip the deletion code. If the response to the is OK, then change the flag, and recall this method with the parameters you saved.

Hopefully this quick thought is helpful.

thank you for your help,

i wanted an alert so that the the user chooses why he deleting it, like over priced, clerk error, void (they didn't want it anymore), or cancel just for face.

try to use the given code before your code perform the delete statement. you may add in other feature in otherButton Titles. to perform optional choice.

UIAlertView *alertmsg=[[UIAlertView alloc]initWithTitle

"Alert Message" message

"Data going to be remove" delegate:nil cancelButtonTitle

"Close" otherButtonTitles:nil];

[alertmsg show];
