Alternative to UIAlertView for iOS 9?

Question

UAlertView is deprecated in iOS 9 and later. What would be an alternative?

UIAlertView *new = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Your InApp Purchases were successfully restored" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[new show];

Solution 1

You can use this code to replace an alert view:

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];           
[alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:alertController animated:YES completion:nil];

If you need multiple actions you can use:

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:[UIAlertAction actionWithTitle:@"Button 1" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
    // action 1
}]];
[alertController addAction:[UIAlertAction actionWithTitle:@"Button 2" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
    // action 2
}]];
[alertController addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
    [self dismissViewControllerAnimated:YES completion:nil];
}]];           
[self presentViewController:alertController animated:YES completion:nil];

Solution 2

You get often detailed information including the replacement suggestion by ⌘-clicking on the symbol which displays the class/method declaration.

In case of UIAlertView you will see

"UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead"

  UIAlertController * alert=   [UIAlertController
                             alertControllerWithTitle:@"Info"
                             message:@"You are using UIAlertController"
                               preferredStyle:UIAlertControllerStyleAlert];

   UIAlertAction* ok = [UIAlertAction
                    actionWithTitle:@"OK"
                    style:UIAlertActionStyleDefault
                    handler:^(UIAlertAction * action)
                    {
                        [alert dismissViewControllerAnimated:YES completion:nil];

                    }];
  UIAlertAction* cancel = [UIAlertAction
                         actionWithTitle:@"Cancel"
                       style:UIAlertActionStyleDefault
                       handler:^(UIAlertAction * action)
                       {
                           [alert dismissViewControllerAnimated:YES completion:nil];
                        }];
 [alert addAction:ok];
 [alert addAction:cancel];

 [self presentViewController:alert animated:YES completion:nil];

Solution 4

I made a category for that:

+ (void)alertViewWithTitle:(NSString *)aTitle message:(NSString *)aMessage viewController:(UIViewController *) aVC
{
    UIAlertController * alert = [UIAlertController
                                 alertControllerWithTitle:aTitle ? aTitle : @""
                                 message:aMessage
                                 preferredStyle:UIAlertControllerStyleAlert];

    UIViewController *topVC = aVC ? aVC : [UIApplication sharedApplication].keyWindow.rootViewController;
    [topVC presentViewController:alert animated:YES completion:nil];
}

The parameters aTitle and aVC are optional but aVC should be used if known.

PS: avoid the "new" as a variable name this is a reserved word, I actually don't know if it will compile though.

UIAlertController has been around since iOS 8.

This takes so much code to implement... What are they thinking? The ability to handle responses without a delegate is a nice addition though.

@Kundapra Hudga, why did you choose to use dispatch_async for [self presentViewController:alertController animated:YES completion:nil]; ?

[Kirit Modi]

You are use the UIAlertController, See for Swift AlertController tutorial : iosdevcenters.blogspot.com/2016/03/…

Why presentViewController is called from dispatch queue?
