Closed 7 years ago.
I am using AlertView since release of iOS8,but after release of iOS8 UIAlertView is replaces by UIAlertViewController. Then how to use it as a UIAlertView.
AlertView in Swift in ios8
var alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
UIAlertController * myAlert= [UIAlertController
alertControllerWithTitle:#"My Alert"
message:#"put a message here"
preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:MyAlert animated:YES completion:nil];
if ([UIAlertController class])
{
// use UIAlertController
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"Enter Folder Name"
message:#"Keep it short and sweet"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action){
//Do Some action here
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
NSLog(#"cancel btn");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[self presentViewController:alert animated:YES completion:nil];
use this code

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
I am new to Objective C but have been working on Swift for a while now. I assumed Objective c to be logically similar to swift. I have to present an alert controller while I am processing a json data request; so I had to use dispatch async to get it to work in swift. Here's the code I used in Swift:
func alertMessage(message : String) -> Void {
let alert = UIAlertController(title: "Alert", message: message, preferredStyle: .Alert)
let okAction = UIAlertAction(title: "OK", style: .Default, handler: nil)
alert.addAction(okAction)
dispatch_async(dispatch_get_main_queue(),{
self.presentViewController(alert, animated: true, completion: nil)
})
}
But I tried to do the same thing in objective C like so
- (void)alertMessage : (NSString*) message {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Alert" message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:NULL];
[alert addAction:okAction];
[dispatch_async(dispatch_get_main_queue(), ^(void){
[self presentViewController:alert animated:true completion:NULL];
})];
}
I'm getting an error "expected identifier". What am I doing wrong?
Its just syntax error. Try following
- (void)alertMessage : (NSString*) message {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Alert" message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:NULL];
[alert addAction:okAction];
dispatch_async(dispatch_get_main_queue(), ^(void){
[self presentViewController:alert animated:true completion:NULL];
});
}
Because “dispatch_async” is a C function, you should call it like this.
- (void)alertMessage : (NSString*) message {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Alert" message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:NULL];
[alert addAction:okAction];
dispatch_async(dispatch_get_main_queue(), ^{
[self presentViewController:alert animated:true completion:nil];
});
}
Can try now
- (void)alertMessage : (NSString*) message {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Alert" message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:NULL];
[alert addAction:okAction];
dispatch_async(dispatch_get_main_queue(), ^(void){
[self presentViewController:alert animated:true completion:nil];
});
}
Output:
Happy coding..
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 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];
}
I have created an alert as follows
UIAlertView *alert1 = [[UIAlertView alloc]
initWithTitle:#"Title"
message:#"message"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:nil];
[alert1 show];
But it does not display the title. How can I fix this?
I try in Xcode 5.1.1 in your code is working fine in my Xcode, see the output
and i also try in Xcode 6.0.1 your code is working fine in my Xcode, see the output
if u r using in Xcode 6.0.1 in swift
UIAlertView is deprecated. Use UIAlertController with a preferredStyle of
UIAlertControllerStyleAlert instead.
UIAlertController * alert1 = [UIAlertController alertControllerWithTitle:#"Title" message:#"Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* aaction = [UIAlertAction actionWithTitle:#"okay" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
[alert1 dismissViewControllerAnimated:YES completion:nil];
}];
[alert1 addAction:aaction];
[self presentViewController:alert1 animated:YES completion:nil];
another choice
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .Alert)
let defaultAction = UIAlertAction(title: "OK", style: .Default, handler: nil)
alertController.addAction(defaultAction)
presentViewController(alertController, animated: true, completion: nil)
need more help use this link http://www.appcoda.com/uialertcontroller-swift-closures-enum/
Try this for iOS 8
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"AlertView" message:#"I am an AlertView" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
I have just removed the following method from my ViewController category class and it's working fine!
- (void)setTitle:(NSString *)title
{
// My Code
}
From Xcode 6.0 UIAlertView class:
UIAlertView is deprecated. Use UIAlertController with a preferredStyle
of UIAlertControllerStyleAlert instead.
On swift ( iOS 8 and OS X 10.10 ), you can do this:
var alert = UIAlertController(title: "Alert Title", message: "Alert Message", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:handleCancel))
alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (ACTION :UIAlertAction!)in
println("User click Ok button")
}))
self.presentViewController(alert, animated: true, completion: nil)
func handleCancel(alertView: UIAlertAction!)
{
println("User click cancel button")
}
You can use following code using UIAlerController for XCode 6 and IOS 8
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Title"
message:#"Your Message"
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];
Hope it is useful to you..
