I want to allow users to copy/cut but mainly PASTE data from other apps into my app. I need to allow them to paste data in UIAlertView, when they are logging to the app. How can i make it?
This is my code:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:[NSString stringWithFormat:NSLocalizedString(#"enter_login", nil)]
delegate:self
cancelButtonTitle:#"Ok"
[alert setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
[[alert textFieldAtIndex:0] setKeyboardType:UIKeyboardTypeEmailAddress];
[[alert textFieldAtIndex:1] becomeFirstResponder];
[UserDefaultsServices resetLoginCredentials];
[UserDefaultsServices resetLoginData];
self.alertView = alert;
[alert show];
It does this:
show what my code does, I need to allow users to paste data in password TextField
You can use this answer for swift versions :
Objective C version of shared answer is :
- (IBAction)showAlert:(id)sender {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"Add New Name" message:#"Your message" preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.placeholder = #"Name";
}];
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.placeholder = #"Password";
textField.secureTextEntry = true;
}];
UIAlertAction *saveAction = [UIAlertAction actionWithTitle:#"Save" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
// here you can access your textfields' texts
NSString *textField1 = alertController.textFields[0].text;
NSString *textField2 = alertController.textFields[1].text;
NSLog(#"Saving %# %#", textField1, textField2);
}];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
// here you can access your textfields' texts
NSString *textField1 = alertController.textFields[0].text;
NSString *textField2 = alertController.textFields[1].text;
NSLog(#"Canceled %# %#", textField1, textField2);
}];
[alertController addAction:saveAction];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
}
Above code work like this :
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;
I have a UIAlertController, which contains a textfield and 2 buttons: OK and Cancel. i want to retrieve the text that the user entered in the textfield when he presses OK, but because the textfield is in a block i cant access the textField.text field that is inside the block from the OK button block. how do i access it and use the text entered by the user? see my code below.
- (IBAction)saveItinerary:(id)sender
{
NSString *itineraryNameInput = [[NSString alloc] init];
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Save Itinerary"
message:#"Enter Name for the Itinerary"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
{
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = #"Name";
textField.text = itineraryNameInput;
}];
NSLog(#"name = %#", itineraryNameInput);
[self presentViewController:alert animated:YES completion:nil];
}
Use the textFields property of the UIAlertController.
UITextField *textField = alert.textFields.firstObject;
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"]) {

}
}
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];
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];
