- (void) presentSheet {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: #"Enter Information"
message:#"Specify the Name and URL" delegate:self cancelButtonTitle:#"Cancel"otherButtonTitles:#"OK", nil];
[alert addTextFieldWithValue:#"" label:#"Enter Name"];
[alert addTextFieldWithValue:#"http://" label:#"Enter URL"];
UITextField *tf = [alert textFieldAtIndex:0];
tf.clearButtonMode = UITextFieldViewModeWhileEditing;
tf.keyboardType = UIKeyboardTypeAlphabet;
tf.keyboardAppearance = UIKeyboardAppearanceAlert;
tf.autocapitalizationType = UITextAutocapitalizationTypeWords;
tf.autocorrectionType = UITextAutocorrectionTypeNo;
// URL field
tf = [alert textFieldAtIndex:1];
tf.clearButtonMode = UITextFieldViewModeWhileEditing; tf.keyboardType = UIKeyboardTypeURL;
tf.keyboardAppearance = UIKeyboardAppearanceAlert; tf.autocapitalizationType = UITextAutocapitalizationTypeNone; tf.autocorrectionType = UITextAutocorrectionTypeNo;
[alert show];
}

You can now create a UIAlertView with a style.
UIAlertView now has a property - alertViewStyle that you can set to one of the enum values
1. UIAlertViewStyleDefault
2. UIAlertViewStyleSecureTextInput
3. UIAlertViewStylePlainTextInput
4. UIAlertViewStyleLoginAndPasswordInput
Once you've created the alert view, you set it style and display it. After dismissing the alert, you can access the contents of the fields using the textFieldAtIndex property of the alert view.
or else you can use this one also.,
IAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:#"Enter Name"];
[dialog setMessage:#" "];
[dialog addButtonWithTitle:#"Cancel"];
[dialog addButtonWithTitle:#"OK"];
UITextField *nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[nameField setBackgroundColor:[UIColor whiteColor]];
[dialog addSubview:nameField];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 70.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
[nameField release];
Hope this information helps. Thank you.
