UIAlertView clickedButtonAtIndex with presentModalViewController

[howcr]

Hi,

I am trying to call a view via presentModalViewController from a UIAlertView button. The code is below, the NSlog is displayed in the console so I know that code execution is indeed reaching that point. Also, there are no errors or anything displayed:

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

if (buttonIndex != [alertView cancelButtonIndex])
{
    NSLog(@" The username is: %@ AND the password is: %@ ",textField.text,passTextField.text);

 // do some logic in here later 

    CompanyViewController *companyViewController = [[[CompanyViewController alloc] initWithNibName:@"CompanyViewController" bundle:nil] autorelease];  
    [self presentModalViewController:companyViewController animated:YES];
}
[textField resignFirstResponder];
[passTextField resignFirstResponder];

}

The method above belongs to a UIViewController. Below is the interface file:

@interface testingViewController : UIViewController  <UITextFieldDelegate>
{
UITextField *textField;
UITextField *passTextField;
}
@property (nonatomic, retain) UITextField *textField;
@property (nonatomic, retain) UITextField *passTextField;
@property (readonly) NSString *enteredText;
@property (readonly) NSString *enteredPassword;

@end

Any suggestions would be appreciated. Thanks for your time.

[self.view presentModalViewController:companyViewController animated:YES];

Hi,

I'm getting a warning: UIView may not respond to 'presentModalViewController:animated:'

The presentModalViewController is an instance method of UIViewController.

So, since the I am using a UIViewController, the problem is probably with the UIAlertVIew clickedButtonAtIndex method.

I haven't found anything that says you cannot use presentModalViewController from an UIAlertView. Has anyone come across this before?

The reason why I am using the alertview is because I have a button on my apps menu screen that requires a user to login in order to open (like a portal page). So, after I have a successful login I allow the user to view the restricted screen.

I had a similar problem that was solved by waiting to present the view. So you would replace that line with:

[self performSelector:@selector(showCompany) withObject:nil afterDelay:0.0];

And put your present view line in a separate function:

- (void) showCompany {
    CompanyViewController *companyViewController = [[[CompanyViewController alloc] initWithNibName:@"CompanyViewController" bundle:nil] autorelease];  
    [self presentModalViewController:companyViewController animated:YES];
