I have created an alert as follows :
// UIAlertView
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"WARNING" message:#"Are you sure you want to quit ?" delegate:nil cancelButtonTitle:#"Confirm" otherButtonTitles:#"Cancel", nil];
[alertView show];
// or UIAlertController
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"WARNING" message:#"Are you sure you want to quit ?" preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:[UIAlertAction actionWithTitle:#"Confirm" style:UIAlertActionStyleDefault handler:NULL]];
[alertController addAction:[UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleCancel handler:NULL]];
[self presentViewController:alertController animated:YES completion:NULL];
But both the effects are like this :
I try to log the title of alert, but the result is null :
How can I fix this ?
Both of them is work in my side.
Try to use this code:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"WARNING" message:#"Are you sure you want to quit ?" delegate:nil cancelButtonTitle:#"Confirm" otherButtonTitles:#"Cancel", nil];
[alertView show];
[self.view addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(grHandler)]];
}
-(void)grHandler{
// UIAlertController
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"WARNING" message:#"Are you sure you want to quit ?" preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:[UIAlertAction actionWithTitle:#"Confirm" style:UIAlertActionStyleDefault handler:NULL]];
[alertController addAction:[UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleCancel handler:NULL]];
[self presentViewController:alertController animated:YES completion:NULL];
}
#end

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;
UIAlertController *alert = [[UIAlertController alloc] initWithTitle: alertString message:nil
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
I'm having this error:
No visible #interface for 'UIAlertController' declares the selector 'show'
and this : No visible #interface for 'UIAlertController' declares the selector 'initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles:'
This true of step to declare UIAlertController
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
// add action button
UIAlertAction *okAction = [UIAlertAction actionWithTitle:actionTitle style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:okAction]; // add action button to alert controller
// present alert controller in view
[self presentViewController:alertController animated:YES completion:nil];
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];
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];
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];
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.
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"My Title"
message:#"Enter User Credentials"
preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:alert animated:YES completion:nil];
I have use "UIAlertController" on iOS 8 and later. Let see:
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"Success" message:#"Your InApp Purchases were successfully restored" preferredStyle:UIAlertControllerStyleAlert];
And add buttons:
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){
//do something when click button
}];
Remember:
[alertController addAction:okAction];
Then show it:
[self presentViewController:alertController animated:YES completion:nill];
If you want to show a actionsheep, you change
"preferredStyle:UIAlertControllerStyleActionSheet"
I have a problem with my iOS Application. Indeed, I have implanted an UIAlertView with an UITextField inside :
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Message"
message:#"message"
delegate:self
cancelButtonTitle:#"Done"
otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField *textField = [alert textFieldAtIndex:0];
assert(textField);
textField.keyboardType = UIKeyboardTypeDecimalPad;
[alert show];
When I touch the "Done" button, there are no dismiss animation for the keyboard, it's not fluid... So I want to add an animation when the user touch the done button :)
Thanks in advance !
If your deployment target is iOS 8, you can work around this by using UIAlertController:
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Title"
message:#"Message"
preferredStyle:UIAlertControllerStyleAlert];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.keyboardType = UIKeyboardTypeDecimalPad;
}];
[alert addAction:[UIAlertAction actionWithTitle:#"Done" style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:alert animated:YES completion:nil];
I have an UIAlertView which is getting shown perfectly in iOS 7 but in iOS 8, it does not show any buttons or labels. Alert is still visible but just a small white box.
The OK and cancel buttons take their events as well but no texts are visible.
I have used this alert to show on click of a button
- (IBAction)sel_btnLogout:(id)sender {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Logout!" message:#"Are you sure you want to logout?" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
[alert show];
}
I checked the frame in iOS 8: it is giving (0,0,0,0) but in iOS 7 it is giving a definite value.
I also checked for iterating into the subviews of uialertview. In iOS7, it goes in the loop, as it finds alert's subviews. In iOS8, it says there are no subviews of alertView.
Check if the class is available
if ([UIAlertController class])
{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"Alert title" message:#"Alert message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:ok];
[self presentViewController:alertController animated:YES completion:nil];
}
else
{
UIAlertView * alert = [[UIAlertView alloc]initWithTitle:#"Alert title" message:#"Alert message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
With iOS 8 you can set the title instead of the message:
[[[UIAlertView alloc] initWithTitle:#"AlertView in iOS 8." message:nil delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil]show];
UIAlertView is deprecated from iOS 8 for more information visit this
http://nshipster.com/uialertcontroller/.
https://developer.apple.com/LIBRARY/IOS/documentation/UIKit/Reference/UIAlertViewDelegate_Protocol/index.html
So if you're going to write separate code for iOS 7 and iOS 8, you should be using UIAlertController instead:
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"AlertView in iOS 8" message:nil preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:[UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
[self dismissViewControllerAnimated:YES completion:nil];
}]];
[self presentViewController:alertController animated:YES completion:nil];
I got the answer to my issue. The issue was that I was using UIFont+Replacement category in my project. This was working fine on iOS 7 but on iOS 8 it was using few deprecated methods. Due to this, I don't know why, but only my alert view was not showing any labels.
Solution: Deleted the category from the project and set font through xib. Once we place the .tff file of any font in our project workspace, we see those font names in the xib under custom fonts. NO NEED TO USE UIFont+Replacement category.
Please read through the code below to understand how to add the fields and buttons to the alerts.
- (IBAction)UIAlertControllerWithActionSheetTextFields:(id)sender {
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Info"
message:#"You are using UIAlertController with Actionsheet and text fields"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction
actionWithTitle:#"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
NSLog(#"Resolving UIAlert Action for tapping OK Button");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
UIAlertAction* cancel = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
NSLog(#"Resolving UIAlertActionController for tapping cancel button");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField * textField) {
textField.accessibilityIdentifier = #"usernameTextField";
textField.placeholder = #"Enter your username";
textField.accessibilityLabel = #"usernameLabel";
}];
[alert addTextFieldWithConfigurationHandler:^(UITextField * textField) {
textField.placeholder = #"Enter your password";
textField.accessibilityIdentifier = #"paswordTextField";
textField.accessibilityLabel = #"passwordLabel";
}];
[self presentViewController:alert animated:YES completion:nil];
}
and if you need a project to completely refer the types of Alerts that are available in IOS, please follow my project from the below URL:
Alert variations in IOS
in iOS 8 you need to replace UIAletrview and UIActionSheet with UIAlertcontroller . You read first This documentation in apple forum
Apple Alertcontroller
You can check that code
if (([[[UIDevice currentDevice] systemVersion] compare:#"8.0" options:NSNumericSearch] == NSOrderedAscending))
{
// use UIAlertView
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:Title message:desc delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
else {
// use UIAlertController
UIAlertController *alert = [UIAlertController alertControllerWithTitle:Title message:desc preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:okAction];
[self presentViewController:alert animated:YES completion:nil];
}
let alert = UIAlertController(title: "Warning" as String , message: messageString as String, preferredStyle: .Alert)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default)
{
UIAlertAction in
self.dismissViewControllerAnimated(true, completion: nil)
}
// Add the actions
alert.addAction(okAction)
self.presentViewController(alert, animated: true, completion: nil)
i think this is not UIAlertview Issues.
please check this work fine..
i think your code issues...........
in any view controller put this code in viewDidLoad Like below:
- (void)viewDidLoad
{
[super viewDidLoad];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"My message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
[alert show];
}
