Alertview with integer - ios

Hello to everyone i would like to place my thinking about an alertview. I am thinking to create an Uialertview which will prompt the user to input two integers. Then i would like to retrieve these two integers and put the one on a timer and the second in an sql statement. So if anyone can help on how to implement that i would apreciate it. Thank you all.
Here is my code until now
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
alertView.alertViewStyle=UIAlertViewStylePlainTextInput;
NSLog(#"Entered: %#", [[alertView textFieldAtIndex:0] text]);
[alertView show];

You need to use delegate methods of UIAlterView.
First of all make "self a delegate" instead of nil.
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
Than add this function to your class:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
UITextField *field = [alertView textFieldAtIndex:0];
NSLog(#"%#", field.text);
}
To be 100% correct add also in your header class information that you implement this protocol .

// Try this
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
alertView.alertViewStyle=UIAlertViewStylePlainTextInput;
[alertView textFieldAtIndex:0].delegate = self;
[alertView show];
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(#"Entered: %#", [[alertView textFieldAtIndex:0]text]);
}

UIAlertView clickedButtonAtIndex not called when text field is in

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

how to get UIAlertView otherButtons' title?

-(void) alertView: (UIAlertView *) alertVw clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *str = [NSString stringWithFormat:#"%d 。", buttonIndex];
UIAlertView *newAlertVw = [[UIAlertView alloc] initWithTitle:#"INFO" message:str delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[newAlertVw show];
}
UIAlertView *alertVw = [[UIAlertView alloc] initWithTitle:#"TITLE"
message:#"box message"
delegate:self
cancelButtonTitle:#"hide"
otherButtonTitles:#"T1", #"T2", nil];
[alertVw show];
if user touched the one of otherButtons, yes, we know which button that user touched.
then, how can I to get the title of button that user just touched?
thanks.
With the delegate on your UIAlertView set to self you can use this:
-(void)alertView:(UIAlertView*)alertView didDismissWithButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(#"Button Title -----> %#",[alertView buttonTitleAtIndex:buttonIndex]);
// or you can check if it equals to string
if([[alertView buttonTitleAtIndex:buttonIndex]isEqual:#"Enter"])
{
// your code goes here
}
}
The method is buttonTitleAtIndex: and the info is simply found on the UIAlertView doc page.
https://developer.apple.com/library/ios/documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html#//apple_ref/occ/instm/UIAlertView/buttonTitleAtIndex:
I advise you to refer to the doc as often as you can this is how you will learn and remember.
Actually, if you want to use the delegate method you have to use -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex.
and not
-(void)alertView:(UIAlertView*)alertView didDismissWithButton At Index:(NSInteger)buttonIndex
see: https://developer.apple.com/library/ios/documentation/uikit/reference/UIAlertViewDelegate_Protocol/UIAlertViewDelegate/UIAlertViewDelegate.html#//apple_ref/occ/intfm/UIAlertViewDelegate/alertView:didDismissWithButtonIndex:
I guess it was just a typo of Pancho.

Parse for iOS using reset parse function

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];
}

is possible to remove previous alert view?

i have create two UIAlertView views in one method. Code like below
-(void) alert{
UIAlertView *alert_1 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 1” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_1 show];
UIAlertView *alert_2 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 2” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];

}
after call this method. iPhone app will appear popup for 2 times.
first appear is alert_1, disappear alert_1 and appear alert_2
after user press ok button in alert_2 thn appear alert_1
should be remove alert_1 when appear alert_2
is possible to remove previous alert view?
Send message - (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated to alert1.
UIAlertView *alert_1 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 1” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_1 show];
[alert_1 dismissWithClickedButtonIndex:0 animated:YES];
UIAlertView *alert_2 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 2” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_2 show];
I am not clear about what your requirement is. But from what I understood you want alert_2 to popup first and when clicked on the "OK" button you want to dismiss that alert view and popup alert_1
- (void) alertview
{
alert_1 = [[UIAlertView alloc] initWithTitle:#"Alert 1" message:#"Message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert_1 setTag:1];
alert_1.delegate = self;
alert_2 = [[UIAlertView alloc] initWithTitle:#"Alert 2" message:#"Message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_2 setTag:2];
alert_2.delegate = self;
[alert_2 show];
}
- (void) alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (alertView.tag ==2)
{
[alert_1 show];
}
}
Please note to declare your alert views in your .h file
Get UIAlertView by its tag or #Property and use this [myAlertView dismissWithClickedButtonIndex:-1 animated:YES];

display alertview while deleting data in plist

I want to delete data in UITableView using plist and i want to put alertview when delete button is pressed. I want to mention that i have used edit button to delete the data from tableview. code of edit button is as follows: for your information.
self.navigationItem.leftBarButtonItem=self.editButtonItem;
Plz help me solve this problem.
thanx in advance.
In your function write :
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: #"" message: #"" delegate: self cancelButtonTitle: #"OK" otherButtonTitles: nil];
alertView.tag = 1;
[alertView show];
[alertView release];
On alert "OK" button pressed
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0)
{
if (alertView.tag == 1)
{
//Do your code
}
}
}
Hope it helps...
on you button action write:-
-(IBAction)btnPressed
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"" message:#"" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
}
- (void)alertView:(UIAlertView *)alert didDismissWithButtonIndex:(NSInteger)buttonIndex
{
}
