UIAlertView first deprecated IOS 9

Posted by: admin November 30, 2017 Leave a comment

Questions:

I have tried several ways to use UIAlertController,instead of UIAlertView. I tried several ways but I cannot make the alert action work.
Here is my code that works fine in IOS 8 and IOS 9 but is showing up with deprecated flags. I tried the elegant suggestion below but I can’t make it function in this context. I need to submit my app and this is the last thing to address. Thank You for any further suggestions. I am a newbie.

#pragma mark - BUTTONS ================================
- (IBAction)showModesAction:(id)sender {
NSLog(@"iapMade: %d", iapMade3);

// IAP MADE ! ===========================================
if (!iapMade3) {

    //start game here
    gamePlaysCount++;
    [[NSUserDefaults standardUserDefaults]setInteger:gamePlaysCount forKey:@"gamePlaysCount"];
    NSLog(@"playsCount: %ld", (long)gamePlaysCount);

    if (gamePlaysCount >= 4) {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
                                                     message: THREE_PLAYS_LIMIT_MESSAGE

From iOS8 Apple provide new UIAlertController class which you can use instead of UIAlertView which is now deprecated, its is also stated in depreciation message

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

So you should use something like this

UIAlertController * alert = [UIAlertController
                alertControllerWithTitle:@"Title"
                                 message:@"Message"
                          preferredStyle:UIAlertControllerStyleAlert];



UIAlertAction* yesButton = [UIAlertAction
                    actionWithTitle:@"Yes, please"
                              style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction * action) {
                                //Handle your yes please button action here
                            }];

UIAlertAction* noButton = [UIAlertAction
                        actionWithTitle:@"No, thanks"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   //Handle no, thanks button                
                                }];

[alert addAction:yesButton];
[alert addAction:noButton];

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

//Calling     
[self showMessage:@"There is no internet connection for this device"
                    withTitle:@"Error"];

//Method

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{

 UIAlertController * alert=   [UIAlertController
                                  alertControllerWithTitle:title
                                  message:message
                                  preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

        //do something when click button
    }];
    [alert addAction:okAction];
    UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    [vc presentViewController:alert animated:YES completion:nil];
}

If you want to use this alert in NSObject class you should use like:

-(void)showMessage:(NSString*)message withTitle:(NSString *)title{
dispatch_async(dispatch_get_main_queue(), ^{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

    }]];

    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:^{
    }];
});
}

Swift version of new implementation is :

 let alert = UIAlertController(title: "Oops!", message:"your message", preferredStyle: .Alert)
 alert.addAction(UIAlertAction(title: "Okay.", style: .Default) { _ in })
 self.presentViewController(alert, animated: true){}

Xcode 8 + Swift

Assuming self is a UIViewController:

func displayAlert() {
    let alert = UIAlertController(title: "Test",
                                  message: "I am a modal alert",
                                  preferredStyle: .alert)
    let defaultButton = UIAlertAction(title: "OK",
                                      style: .default) {(_) in
        // your defaultButton action goes here
    }

    alert.addAction(defaultButton)
    present(alert, animated: true) { 
        // completion goes here
    }
}

Use UIAlertController instead of UIAlertView

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{
UIAlertController * alert=   [UIAlertController
                              alertControllerWithTitle:title
                              message:message
                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    //do something when click button
}];
[alert addAction:okAction];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
[vc presentViewController:alert animated:YES completion:nil];

Make UIAlertController+AlertController Category as:

UIAlertController+AlertController.h

typedef void (^UIAlertCompletionBlock) (UIAlertController *alertViewController, NSInteger buttonIndex);

@interface UIAlertController (AlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock;
@end

UIAlertController+AlertController.m

@implementation UIAlertController (NTAlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock {

    UIAlertController *alertController = [self alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];

    if(cancelButtonTitle != nil) {

        UIAlertAction *cancelButton = [UIAlertAction
                                       actionWithTitle:cancelButtonTitle
                                       style:UIAlertActionStyleCancel
                                       handler:^(UIAlertAction *action)
                                       {
                                           tapBlock(alertController, ALERTACTION_CANCEL); // CANCEL BUTTON CALL BACK ACTION
                                       }];
        [alertController addAction:cancelButton];

    }

    if(otherButtonTitle != nil) {

        UIAlertAction *otherButton = [UIAlertAction
                                   actionWithTitle:otherButtonTitle
                                   style:UIAlertActionStyleDefault
                                   handler:^(UIAlertAction *action)
                                   {
                                       tapBlock(alertController, ALERTACTION_OTHER); // OTHER BUTTON CALL BACK ACTION
                                   }];

        [alertController addAction:otherButton];
    }

    [controller presentViewController:alertController animated:YES completion:nil];

    return alertController;
}

@end

in your ViewController.m

[UIAlertController showAlertIn:self WithTitle:@"" message:@"" cancelButtonTitle:@"Cancel" otherButtonTitles:@"Other" tapBlock:^(UIAlertController *alertController, NSInteger index){

 if(index == ALERTACTION_CANCEL){

 // CANCEL BUTTON ACTION
 }else
if(index == ALERTACTION_OTHER){

 // OTHER BUTTON ACTION
 }

 [alertController dismissViewControllerAnimated:YES completion:nil];

 }];

NOTE: If you want to add more than two buttons then add another
more UIAlertAction to the UIAlertController.

Answers:

I tried the above methods, and no one can show the alert view, only when I put the presentViewController: method in a dispatch_async sentence:

dispatch_async(dispatch_get_main_queue(), ^ {
[self presentViewController:alert animated:YES completion:nil];
});

Refer to Alternative to UIAlertView for iOS 9?.

Check this:

UIAlertController *alertctrl =[UIAlertController alertControllerWithTitle:@"choose Image" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *camera =[UIAlertAction actionWithTitle:@"camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self Action];  //call Action need to perform 
    }];

[alertctrl addAction:camera];
-(void)Action
