how to move to next view controller after showing alertview - iphone

Question

I have iPhone and I want that when AlertView is shown and user presses OK button after that view should be changed but it is not happening.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Thank you" message:#"" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
return;
[self moveToView];
-(void)moveToView
{
MainViewController*targetController=[[MainViewController alloc]init];
[self.navigationController pushViewController:targetController animated:YES];
}

Answer 1

Please use UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
// Code to move to next view
[self moveToView];
}
Note: Implement the UIAlertViewDelegate in your interface Declaration. Also while declaring UIAlertView set the delegate to self.
Hope this helps you.

Answer 2

Its simple. Implement UIAlertViewDelegate and put code there.
- (void) alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
MainViewController*targetController=[[MainViewController alloc]init];
[self.navigationController pushViewController:targetController animated:YES];
[targetController release];
}

Answer 3

in .h , implemented UIAlertViewDelegate
#interface ClassName : ParentClassName <UIAlertViewDelegate>
in .m , Add this method,
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
[self moveToView];
}

Answer 4

Implement alert view's delegate:
In your yourClass.h file:
#interface yourClass : UIViewController<UIAlertViewDelegate>{
}
#end
In your yourClass.m file:
#implementation yourClass
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{
[self moveToView];
}
#end

Answer 5

Well , you are setting self as the delegate of the UIAlertView. That is correct and it's the first step you must take. After that go ahead and implement this method :
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[self moveToView];
}
You can also make a switch statement here to see what button was pressed. But since you only have the OK button on the AlertView , it's not necessary.
Hope this helps.
Cheers!

Answer 6

Implement your code in - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex method and also add UIAlertViewDelegate in your class .h file.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
NSLog(#"The index: %d",buttonIndex);
MainViewController*targetController=[[MainViewController alloc]init];
[self.navigationController pushViewController:targetController animated:YES];
[targetController release];
}
I think it will be helpful to you.
