Question

When I display the alert to the user, if he clicked on the OK button I need to move him to another screen, how can I do that:

UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"TopStation"
                                                message :@"Your internet connection is down, you will be redirected to the previous screen"
                                                delegate:nil
                                       cancelButtonTitle:@"OK"
                                       otherButtonTitles:nil];
    [alert show];
    [alert release];

Answer 1

What you’ll need to do is implement the UIAlertView delegate in the method you are using.

So if you have the class

@interface MyClass: UIViewController {

You’ll want to change it to use

@interface MyClass:UIViewController <UIAlertViewDelegate> {

Then in the implementation file you just need to implement the method

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

From there you can move on.
