UIAlertView first deprecated IOS 9 - ios

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];
}
}

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];

//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
}
}

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.

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];
}

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?.

-(void)showAlert{
UIAlertController* alert = [UIAlertController alertControllerWithTitle:#"Title"
message:#"Message"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
}
[self showAlert]; // calling Method

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
{
}

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];

How to popup AlertView on successful check of pin in ObjC?

I am trying to create a small app in which user need to enter the pin on the correct pin it will say correct pin else wrong but I am not sure if my logic is correct below. I am using the Xcode10 on the latest Mac version.
- (IBAction)validatePin:(id)sender {
[ViewController checkPin:self.textPin.text.integerValue];
}
+(BOOL)checkPin:(NSInteger)pin {
if (pin == 1408)
{
//[UIAlertController alertControllerWithTitle:#"Pin" message:#"Success" preferredStyle:UIAlertControllerStyleAlert];
[[UIAlertView alloc] initWithTitle:#"Alert Title"
message:#"are you sure?"
delegate:self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes", nil];
return YES;
}
[UIAlertController alertControllerWithTitle:#"Pin" message:#"Fail" preferredStyle:UIAlertControllerStyleAlert];
return NO;}
I have tried both the UIAlertView and UIAlertController method but I get no response to the app. Can someone correct this code in ObjC?
Thanks
There's no need to create method, you can directly check and shoe an alert like this.
- (IBAction)validatePin:(id)sender {
if (self.textPin.text.integerValue == 1408) {
UIAlertController* alert = [UIAlertController alertControllerWithTitle:#"Alert Title"
message:#"PIN is Correct"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
}
else {
UIAlertController* alert = [UIAlertController alertControllerWithTitle:#"Alert Title"
message:#"PIN is WRONG"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
}
}
If you want to use your code then change it to this.
- (IBAction)validatePin:(id)sender {
BOOL isValidPin = [ViewController checkPin:self.textPin.text.integerValue];
if (isValidPin) {
// SHOW RIGHT ALERT
}
else {
// SHOW WRONG ALERT
}
}
+(BOOL)checkPin:(NSInteger)pin {
if (pin == 1408) {
return YES;
}
else {
return NO;
}
}

Detect Alert Button Click Event

I have the following implementation to be reused entire app. I store the following code in the Utility.m class.
CustomViewController.m
How can I capture click event in the following
[self presentViewController:[Utility oneButtonDisplayAlert:#"Error" withMessage:#"Please try again later"] animated:YES completion:nil];
Utility.m
+ (UIAlertController *)oneButtonDisplayAlert : (NSString*)title withMessage : (NSString*) message
{
UIAlertController * alert = [UIAlertController
alertControllerWithTitle:title
message:message
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* yesButton = [UIAlertAction
actionWithTitle:#"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//Handle your yes please button action here
}];
[alert addAction:yesButton];
return alert;
}
Add a block parameter to your oneButtonDisplayAlert:withMessage: method. Call that block inside the alert action's handler.
+ (UIAlertController *)oneButtonDisplayAlert:(NSString *)title withMessage:(NSString *)message andOKHandler:(void (^)(void))handler
{
UIAlertController * alert = [UIAlertController
alertControllerWithTitle:title
message:message
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* yesButton = [UIAlertAction
actionWithTitle:#"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
if (handler) {
handler();
}
}];
[alert addAction:yesButton];
return alert;
}
And then call it as:
UIAlertController *alert = [Utility oneButtonDisplayAlert:#"Error" withMessage:#"Please try again later" andOKHandler:^{
// whatever code you need when OK tapped
}];
[self presentViewController:alert animated:YES completion:nil];
Note: Code in this answer might have a typo. Syntax not verified.

UIAlertController how add the tag value in obj c

Using this for UIAlertView
- (void) alertStatus:(NSString *)msg :(NSString *)title :(int) tag
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title
message:msg
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil, nil];
alertView.tag = tag;
[alertView show];
}
But now UIAlertView get deprecated. change my code
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* MyAlert = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:MyAlert];
[self presentViewController:alertController animated:YES completion:nil];
Here how can pass this tag value
alertView.tag = tag;
Help how to pass the tag value in UIAlertController. Thanks advance.
UIAlertController is the UIViewController , so we need to assign the tag for view, soe use alertController.view.tag.
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"sds" message:#"sdf" preferredStyle:UIAlertControllerStyleAlert];
alertController.view.tag = tag;
UIAlertAction* MyAlert = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:MyAlert];
[self presentViewController:alertController animated:YES completion:nil];
update
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"sds" message:#"sdf" preferredStyle:UIAlertControllerStyleAlert];
alertController.view.tag = 3;
UIAlertAction* MyAlert = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action)
{
// OK button tappped.
[self dismissViewControllerAnimated:YES completion:^{
}];
}];
[alertController addAction:MyAlert];
[self presentViewController:alertController animated:YES completion:nil];
create a property of UIAlertController *alertController;, then use this alertController where ever you want. set the tag like this
alertController.view.tag = <YOUR TAG VALUE>;
to get the tag of that alertController, when you click on YES on alertController
//OK button tapped.
[self dismissViewControllerAnimated:YES completion:^{
NSInteger *tag = alertController.view.tag;
}];
Have not any tag property in UIAlertController. You can use block for getting button action.
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Alert"
message:[NSString stringWithFormat:#"Your message"]
preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
//NSLog(#"OK");
}]];
[self presentViewController:alert animated:YES completion:nil];
But you can use tag in this way-
alert.view.tag = 1;

actionSheet:didDismissWithButtonIndex: is deprecated in iOS 8.3. What is the new method I have to use now?

These are deprecated, but I don't find the solution to improve it :
[alert addAction:[UIAlertAction actionWithTitle:NSLocalizedString(#"Take Photo", nil) style:UIAlertActionStyleDefault handler:^(__unused UIAlertAction *action)
{
[self actionSheet:nil didDismissWithButtonIndex:0];
}]];
And:
[[[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:NSLocalizedString(#"Cancel", nil) destructiveButtonTitle:nil otherButtonTitles:NSLocalizedString(#"Take Photo", nil), NSLocalizedString(#"Photo Library", nil), nil] showInView:controller.view];
Finally:
- (void)actionSheet:(__unused UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
switch (buttonIndex)
{
case 0:
{
sourceType = UIImagePickerControllerSourceTypeCamera;
break;
}
case 1:
Many thanks.
You can use UIAlerController as UIActionSheet is deprecated after iOS 8.3.
Please have look at below code for your reference.
UIAlertController* alert = [UIAlertController
alertControllerWithTitle:nil // Must be "nil", otherwise a blank title area will appear above our two buttons
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* button0 = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action)
{
// UIAlertController will automatically dismiss the view
}];
UIAlertAction* button1 = [UIAlertAction
actionWithTitle:#"Camera"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction * action)
{
// The user tapped on "Camera"
}];
UIAlertAction* button2 = [UIAlertAction
actionWithTitle:#"Photo Library"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction * action)
{
// The user tapped on "Camera"
}];
[alert addAction:button0];
[alert addAction:button1];
[alert addAction:button2];
[self presentViewController:alert animated:YES completion:nil];
Hope t his will guide you to get into UIAlterController in replace of UIActionSheet.
Thanks.
From Apple's website, It is clearly said you should use UIAlertController

iOS 7 -(void)setupAlertCtr:(NSString*)choseMenuType compatibility

-(void)setupAlertCtr:(NSString*)choseMenuType
{
self.alertContForNew = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancel = [UIAlertAction actionWithTitle:#"İptal" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action)
{
}];
[self.alertContForNew addAction:cancel];
}
This code work on iOS 8 but when i try to use on iOS 7 get crash whats the problem ideas ?
Because UIAlertController is only support for iOS 8 and later, in iOS 7 we still have to use UIActionSheet or UIAlertView
so you have to put condition like below
if (ios8)// change your condition which check ios8 or later.
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Title" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
UIAlertAction* alertAction1 = [UIAlertAction actionWithTitle:#"Your title" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
{
//do what you want
}];
[alert addAction:cancelAction];
[alert addAction:alertAction1];
[self presentViewController:alert animated:YES completion:nil];
}
else
{
UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:#"Title" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Your Title",nil];
[actionSheet showInView:self.view];
}
and for iOS 7 you have to implement <UIActionSheetDelegate> and its method
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex) {
case 0:
//do what you want.
break;
case 1:
break;
default:
break;
}
}
