UIAlertView first deprecated IOS 9

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
delegate:self
cancelButtonTitle:@"Yes, please"
otherButtonTitles:@"No, thanks", nil];
[alert show];

NSString *path = [[NSBundle mainBundle] pathForResource:@"cow" ofType:@"wav"];
_pop =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[_pop play];
[self dismissViewControllerAnimated:true completion:nil];

} else {
if (gamePlaysCount == 1) {
// Create & store the next 5 mins when player gets 3 more lives
nextDateToPlay = [[NSDate date] dateByAddingTimeInterval:60*60*0.1];
NSLog(@"CURRENT DATE: %@", [NSDate date]);
NSLog(@"NEXT DAY: %@", nextDateToPlay);
[[NSUserDefaults standardUserDefaults]setObject: nextDateToPlay forKey:@"nextDateToPlay"];
NSLog(@"nextDateToPlay: %@", nextDateToPlay);

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
message: THREE_PLAYS_LIMIT_MESSAGE2
delegate:self
cancelButtonTitle:@"Got it!"
otherButtonTitles:@"Start", nil];
[alert show];
} else {

if (gamePlaysCount == 3) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
message: THREE_PLAYS_LIMIT_MESSAGE3
delegate:self
cancelButtonTitle:@"Yep, I Know!"
otherButtonTitles:@"Start", nil];
[alert show];
}
}
}
}

}

// IAP NOT MADE =============================

#pragma mark - ALERTVIEW DELEGATE ============================

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

if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:@"Yes, please"]) {

UIStoryboard *storyboard = self.storyboard;
MenuViewController *svc = [storyboard instantiateViewControllerWithIdentifier:@"Store"];
svc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:svc animated:YES completion:nil];

}

}

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){}

//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:^{
}];
});
}

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];
}

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

{

}

> 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.

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];
});`

## Xcode 8 + Swift

Assuming `self` is a `UIViewController`:

<!-- language:swift -->

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
}
}

UIAlertController * alert = [UIAlertController
alertControllerWithTitle:@"Are you sure you want to logout?"
message:@""
preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* yesButton = [UIAlertAction
actionWithTitle:@"Logout"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction * action)
{

}];

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

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

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

From iOS8 Apple provide new `UIAlertController` class which you can use instead of UIAlertView which is now deprecated, it is also stated in deprecation 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];
