To retrieve the text of a text field in the UIAlertView you can use the textFieldAtIndex: method. You don't need to involve the text field delegate at all.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
UITextField *textField = [alertView textFieldAtIndex:0]; // adjust the index if you have more than one text field.
NSLog(#"Text: %#", textField.text);
}
Original Answer
You have a couple of options here.
Option 1
Store a reference to the text field as a property, it seems likely you are already doing this.
#property (nonatomic, weak) IBOutlet UITextField *textField;
This can then be accessed directly from the UIAlertView delegate method, assuming the delegate is the same object that has the reference to the text field:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSLog(#"Text: %#", self.textField.text);
}
Option 2
If for some reason you don't have a reference to your text field you can get it from the textFieldDidEndEditing: delegate method, firstly create a property to store the text:
#property (nonatomic, copy) NSString *textFieldText;
Then update that when the text field delegate method is called.
- (void)textFieldDidEndEditing:(UITextField *)textField {
self.textFieldText = textField.text;
}
Then you can access this property in the UIAlertView delegate method:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSLog(#"Text: %#", self.textFieldText);
}

This code is working for me:
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:#"" message:[NSString stringWithFormat:#"Do you want to call?"] delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeNumberPad;
[alertTextField setTextAlignment:NSTextAlignmentCenter];
[alert show];
and delegates:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex==1) {
return;
}
UITextField *title1;// = [alertView textFieldAtIndex:0];
title1= [alertView textFieldAtIndex:0];
NSString *messageStr = title1.text;
if ([messageStr isEqualToString:#""]) {
return;
}}

you just declare NSString object in
#interface LoginDialogVC ()
{
NSString strText;
}
#end
#implementation LoginDialogVC
-(void)textFieldDidEndEditing:(UITextField *)textField {
strText = textField.text;
}
after that use strText whenever you want to use.
