When i pull the tableView downwards, an alertView should appear with a login text field.
The alert has to come but the textField is not to be selected.
Once i click on this textField, then the keyboard should appear.
For this i am using this code:
- (void)toggleCells:(UIRefreshControl*)refreshControl
{
message = [[UIAlertView alloc] initWithTitle:#"Create a new list"
message:#""
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
[message setTag:1001];
//[message textFieldAtIndex:0].delegate = self;
[refreshControl beginRefreshing];
[message show];
[refreshControl endRefreshing];
//...
}
try: (not so nice but a quick-fix)
message = [[UIAlertView alloc] initWithTitle:#"Create a new list"
message:nil
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
[message setTag:1001];
[[message textFieldAtIndex:0] setDelegate:self]; //you'll surely need it later
[message show];
[[message textFieldAtIndex:0] resignFirstResponder]; //after showing the alertView
NOTE: The method above ain't really nice.
Alternative Method:
NOTE: declare "BOOL skipAlertTextField;" in the .h
- (void)toggleCells:(UIRefreshControl*)refreshControl {
//...
message = [[UIAlertView alloc] initWithTitle:#"Create a new list"
message:nil
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
[message setTag:1001];
[[message textFieldAtIndex:0] setDelegate:self];
skipAlertTextField = YES; //important
[message show];
//...
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
if(textField.tag == 1001 && skipAlertTextField) {
skipAlertTextField = NO;
return NO;
}
return YES;
}
Try this
UIAlertView *av = [[UIAlertView alloc]initWithTitle:#"SayWhat" message:#"Please enter Email address" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av setAlertViewStyle:UIAlertViewStylePlainTextInput];
[[av textFieldAtIndex:0] setPlaceholder:#"Email address"];
[[av textFieldAtIndex:0] setDelegate:self];
[av show];
[[av textFieldAtIndex:0] resignFirstResponder];

I am using this code for Update Email Address and Forgot Password but their is a problem when I click on 'ForgotPassword' button it's work properly but when I click on 'UpdateEmail' button it not work properly it call the UIAlert for 'ForgotPassword' button and I am trying to call" else if (self.ForgotPassword.tag == 1) part of -(Void)alertView " for when I press 'UpdateEmail' UIButton.
//Forgot method for ForgotPassword
-(IBAction)ForgotPassword:(id)sender
{
UIAlertView * forgotPassword=[[UIAlertView alloc] initWithTitle:#"Forgot Password" message:#"Please enter your email id" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
forgotPassword.alertViewStyle=UIAlertViewStylePlainTextInput;
[forgotPassword textFieldAtIndex:0].delegate=self;
[forgotPassword show];
}
//Method for Update Email Address
-(IBAction)UpdateEmail:(id)sender
{
if ([PFUser currentUser])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Update Email"
message:#"Enter Your Email Address"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok",nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
}
else
{
UIAlertView *myAlert1 = [[UIAlertView alloc]
initWithTitle:#"Please First Loginig"
message:#"Please First Loging"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok",nil];
[myAlert1 show];
}
}
// Method for Alert View
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
self.ForgotPassword.tag=0;
self.UpdateEmail.tag=1;
if (self.ForgotPassword.tag == 0){
if(buttonIndex ==1){
NSLog(#"ok button clicked in forgot password alert view");
NSString *femailId=[alertView textFieldAtIndex:0].text;
if ([femailId isEqualToString:#""]){
UIAlertView *display;
display=[[UIAlertView alloc] initWithTitle:#"Email" message:#"Please enter password for resetting password" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles: nil];
[display show];
}else{
[PFUser requestPasswordResetForEmailInBackground:femailId block:^(BOOL succeeded, NSError *error){
UIAlertView *display;
if(succeeded){
display=[[UIAlertView alloc] initWithTitle:#"Password email" message:#"Please check your email for resetting the password" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles: nil];
}else{
display=[[UIAlertView alloc] initWithTitle:#"Email" message:#"Email doesn't exists in our database" delegate:nil cancelButtonTitle:#"Cancel" otherButtonTitles: nil];
}
[display show];
}];
}
}
}else if (self.ForgotPassword.tag == 1){
PFUser *user = [PFUser currentUser];
user[#"email"] = [alertView textFieldAtIndex:0].text;
[user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error){
if (succeeded){
UIAlertView *myAlert1 = [[UIAlertView alloc]
initWithTitle:#"Email Upadated!"
message:#"your Email is Updated"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok",nil];
[myAlert1 show];
//NSLog(#"Success");
}else{
UIAlertView *myAlert1 = [[UIAlertView alloc]
initWithTitle:#"Email is NOT Update"
message:#"Email is alredy registred"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok",nil];
[myAlert1 show];
NSLog(#"Error");
}
}];
}
}
You need to give tag to your two different UIAlertView like below.
-(IBAction)ForgotPassword:(id)sender
{
UIAlertView * forgotPassword=[[UIAlertView alloc] initWithTitle:#"Forgot Password" message:#"Please enter your email id" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
forgotPassword.alertViewStyle=UIAlertViewStylePlainTextInput;
[forgotPassword textFieldAtIndex:0].delegate=self;
[forgotPassword show];
forgotPassword.tag = 0; //// Here for forgot password
}
-(IBAction)UpdateEmail:(id)sender
{
if ([PFUser currentUser])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Update Email"
message:#"Enter Your Email Address"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok",nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
alert.tag =1; ///Here for email update
}
}
Then, in -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex, you can detect which alertView's button was clicked.
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
{
if(alertView.tag == 0) /// Because we assigned forgotPassword.tag = 0; above for forgotPassword
{
if(buttonIndex == YOUR_DESIRED_BUTTON_INDEX)
{
///Your code for Forgot Password.
}
}
else if(alertView.tag ==1) /// Because we assigned alert.tag = 1; above for update email
{
if(buttonIndex == YOUR_DESIRED_BUTTON_INDEX)
{
///Your code for Update Email.
}
}
}
When I have the following code the clickedButtonAtIndex delegate method is called:
UIAlertView * alertTextField = [[UIAlertView alloc] initWithTitle:#"Post To Facebook" message:#"What would you like the post to say?" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Continue", nil];
alertTextField.tag = 2;
[alertTextField show];
But when i add in the UIAlertViewStylePlainTextInput in the delegate method is not called.
UIAlertView * alertTextField = [[UIAlertView alloc] initWithTitle:#"Post To Facebook" message:#"What would you like the post to say?" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Continue", nil];
[alertTextField setAlertViewStyle:UIAlertViewStylePlainTextInput];
alertTextField.tag = 2;
[alertTextField show];
Why is this?
ensure that you added <UIAlertViewDelegate> in your view controller and your forget to add alertTextField.delegate = self; Then implement the delegate to receive the event.
UIAlertView * alertTextField = [[UIAlertView alloc] initWithTitle:#"Post To Facebook" message:#"What would you like the post to say?" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Continue", nil];
[alertTextField setAlertViewStyle:UIAlertViewStylePlainTextInput];
alertTextField.delegate = self; // you forget to add this line
alertTextField.tag = 2;
[alertTextField show];
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0) {
NSString *test = [[alertView textFieldAtIndex:0] text];
}
}
UIAlertView no longer available/support in iOS 8 and above so in this place use UIAlertViewController, example for how to use UIAlertViewController see this tutorial
I want to implement a function that allows users to reset their password. I already created a button that displays an alert view and asks for their email, but when I tap ok, it doesn't send an email.
What can I do?
-(IBAction)forget:(id)sender {
[PFUser requestPasswordResetForEmailInBackground:#"email#example.com"];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Email Address" message:#"Enter the email for your account:" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
}
- (IBAction)forget:(id)sender {
[self getEmail];
}
- (void)getEmail {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Email Address" message:#"Enter the email for your account:" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex != [alertView cancelButtonIndex]) {
UITextField *emailTextField = [alertView textFieldAtIndex:0];
[self sendEmail:emailTextField.text];
}
}
- (void)sendEmail:(NSString *)email{
[PFUser requestPasswordResetForEmailInBackground:email];
}
Can we programmatically insert text in UIAlertView's textfield, iOS7
Created UIAlertView with textinput in IOS7.
Can anyone help me with "inserting text programatically in textfield"?
Hopefully this will give answer for your question.
UIAlertView *alertView = [[UIAlertView alloc] init];
alertView.delegate = self;
alertView.title = #"Enter Info";
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView addButtonWithTitle:#"Cancel"];
[alertView addButtonWithTitle:#"OK"];
[alertView textFieldAtIndex:0].text = #"My Text";
[alertView show];
You can achieve this by using this code
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"" message:#"whatever you like" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:#"Cancel", nil];
alert.alertViewStyle=UIAlertViewStylePlainTextInput;
[alert textFieldAtIndex:0].text=#"Hello";
[alert show];
and result will be like this:
Please try to use like this..
UIAlertView* av = [[UIAlertView alloc] init];
[av setDelegate:self];
[av setTitle:#"Hi"];
[av setMessage:nil];
[av addButtonWithTitle:#"Cancel"];
[av addButtonWithTitle:#"OK"];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av textFieldAtIndex:0].text = #"Text";
You can use text property to set text inside textfield.
textFiled.text = #"YOUR TEXT";
I'm currently using this UIAlertView to do a login popup,
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Restricted"
message:#"Please Enter Code to Enable Fields"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Login"
, nil];
alert.alertViewStyle = UIAlertViewStyleSecureTextInput;
[alert show];
However I would like the text input to be a numeric keyboard instead of the regular keyboard
Is there a easy way to do this, or do I have to look into creating a custom UIAleartView
You can try this to change the keyboard type of the UIAlertView's field:
[[alert textFieldAtIndex:0] setDelegate:self];
[[alert textFieldAtIndex:0] setKeyboardType:UIKeyboardTypeNumberPad];
[[alert textFieldAtIndex:0] becomeFirstResponder];
Cool answer but for iOS 7 I have a little adaptation
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
[[alert textFieldAtIndex:0] setDelegate:self];
[[alert textFieldAtIndex:0] resignFirstResponder];
[[alert textFieldAtIndex:0] setKeyboardType:UIKeyboardTypePhonePad];
[[alert textFieldAtIndex:0] becomeFirstResponder];
UIAlertView *alertView1 = [[UIAlertView alloc] initWithTitle:#"Enter File Number" message:#"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alertView1.alertViewStyle = UIKeyboardTypePhonePad;
myTextField = [alertView1 textFieldAtIndex:0];
myTextField.keyboardType=UIKeyboardTypeNumberPad;
[alertView1 setTag:3];
[alertView1 show];
