Answer 1

From iOS 5 the approach above is no longer necessary. Just set the alertViewStyle property to the appropriate style (UIAlertViewStyleSecureTextInput, UIAlertViewStylePlainTextInput, or UIAlertViewStyleLoginAndPasswordInput).
Example:
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Email" message:#"Enter your email:" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
and you can have the response back as
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
UITextField *emailTextField = [alertView textFieldAtIndex:0];
NSLog(#"%#",emailTextField.text);
}

UIAlertView with UITextField:
Usage:
NSString *title = NSLocalizedString(#"Your Title","");
NSString *placeholder = NSLocalizedString(#"Placeholder Text","");
NSString *message = NSLocalizedString(#"A message to the user.","");
NSString *cancel = NSLocalizedString(#"Cancel","");
NSString *okay = NSLocalizedString(#"Continue","");
prompt = [[AlertPrompt alloc] initWithTitle:title
placeholder:placeholder
message:message
delegate:self
cancelButtonTitle:cancel
okButtonTitle:okay];
[prompt show];
[prompt release];
.h
#import <Foundation/Foundation.h>
#interface AlertPrompt : UIAlertView <UITextFieldDelegate>
{
UITextField *textField;
NSString *enteredText;
}
#property(nonatomic,retain) UITextField *textField;
#property (nonatomic, retain, readonly) NSString *enteredText;
- (id)initWithTitle:(NSString *)title placeholder:(NSString *)placeholder message:(NSString *)message delegate:(id)delegate
cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle;
#end
.m
#import ".h"
#implementation AlertPrompt
#synthesize textField;
#synthesize enteredText;
#pragma mark -
#pragma mark AlertPrompt Delegates
- (id)initWithTitle:(NSString *)title placeholder:(NSString *)placeholder message:(NSString *)message delegate:(id)delegate
cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle {
if (self = [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])
{
self.title = title;
self.message = [NSString stringWithFormat:#"%#\n\n\n",message];
self.delegate = delegate;
UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 75.0f, 260.0, 30.0)];
[theTextField setBackgroundColor:[UIColor clearColor]];
theTextField.borderStyle = UITextBorderStyleRoundedRect;
theTextField.textColor = [UIColor blackColor];
theTextField.font = [UIFont systemFontOfSize:18.0];
theTextField.autocapitalizationType = UITextAutocapitalizationTypeWords;
theTextField.keyboardAppearance = UIKeyboardAppearanceAlert;
theTextField.returnKeyType = UIReturnKeyDone;
theTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
theTextField.placeholder = placeholder;
theTextField.delegate = self;
[self insertSubview:theTextField atIndex:0];
self.textField = theTextField;
[theTextField release];
CGAffineTransform translate = CGAffineTransformMakeTranslation(0, -10);
[self setTransform:translate];
}
return self;
}
- (void)show{
[textField becomeFirstResponder];
[super show];
}
- (NSString *)enteredText{
return textField.text;
}
- (void)dealloc{
[textField resignFirstResponder];
[textField release];
[super dealloc];
}
#end
Delegate:
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if([alertView.title isEqualToString:#"Your Title"])
{
if(buttonIndex == 1)
{
/* get the user iputted text */
NSString *inputValue = [(AlertPrompt *)alertView enteredText];
NSLog(#"User Input: %#",inputValue);
{
}
}

Answer 3

UIAlertView *emailAlert=[[UIAlertView alloc]initWithTitle:#"Enter your Email-id" message:#"\n\n" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK",nil];
emailTextField=[[UITextField alloc]initWithFrame:CGRectMake(12,45,260,25)];
[emailTextField becomeFirstResponder];
[emailTextField setBackgroundColor:[UIColor whiteColor]];
emailTextField.clearButtonMode=UITextFieldViewModeWhileEditing;
emailTextField.placeHolder=#"Email";
[emailAlert addSubview:emailTextField];
[emailAlert show];
[emailAlert release];
Use UIAlertView Delegates Methods when OK button is clicked.

Swift version:
var alert = UIAlertView(title: "PostActionTitle", message: "PostActionText", delegate: self, cancelButtonTitle:"PostActionDecline")
alert.alertViewStyle = UIAlertViewStyle.PlainTextInput
alert.addButtonWithTitle("PostActionAccept")
alert.show()
