Forcing UIAlertView into landscape mode

Question

I need to display a UIAlertView in landscape mode. I tried the obvious, setting the transform in the willPresentAlertView: delegate method to no avail:

Answer 1

I was struggling with quite the same issue lately. For me solution was using UIAlertController - cover older handling of UIAlertview and UIActionsheet.

1. Create new controller, which is dedicated from UIAlertController, where you must overloaded methods viewWillAppear and viewWillDisappear, like in example bellow.

AlertViewController.h

#import 

@interface AlertViewController : UIAlertController 

@end

AlertViewController.m

#import "AlertViewController.h"

@interface AlertViewController ()

@end

@implementation AlertViewController

- (void) viewWillAppear:(BOOL)animated {
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI_2)];
}

- (void) viewWillDisappear:(BOOL)animated {
    [self.view setHidden:YES];
}

...

2. implement method for showing alert view where you needed.

   • (void) showInfoAlertView {

         AlertViewController *alert = [AlertViewController alertControllerWithTitle:@"My Alert" message:@"This is an alert." preferredStyle:UIAlertControllerStyleAlert];
     
         UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil];
         [alert addAction:ok];
         [self presentViewController:alert animated:NO completion:nil];
     }
