Default text in UIAlertVIew on show - ios

Question

It appears that there are a number of questions asking this but nothing I have tried works for me. Simply, I would like an UIAlertView with UIAlertViewStylePlainTextInput but with the input box preloaded with a given string when it is displayed - not as a placeholder, but as a default entry. Is this possible?
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert" message:#"message" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[[alert textFieldAtIndex:0] setText:[NSString stringWithFormat:#"%#", #"preloaded string"]];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
The example above uses setText which does not work. I have also tried:
[[alert textFieldAtIndex:0] setPlaceholder:#"text"];
just for interest, but this does not display even the placeholder so maybe I am missing something else.
Any pointers?

Use UIAlertController instead:
let alertController = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.Alert)
alertController.addTextFieldWithConfigurationHandler { (textField) -> Void in
// Configure UITextField here...
textField.placeholder = "Placeholder"
}
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) { (_) -> Void in
let textField = alertController.textFields![0] as UITextField
let value = textField.text ?? "Untitled"
/// Save value here...
}
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
alertController.addAction(okAction)
alertController.addAction(cancelAction)
presentViewController(alertController, animated: true, completion: nil)

you can do it like
AlertView
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"sample" message:#"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Done", nil];
[alert setAlertViewStyle: UIAlertViewStylePlainTextInput];
// Alert style customization
[[alert textFieldAtIndex:0] setDelegate:self];
[[alert textFieldAtIndex:0] setKeyboardType:UIKeyboardTypeNumberPad];
[[alert textFieldAtIndex:0] setText:#"Richard"];
[[alert textFieldAtIndex:0] setPlaceholder:#"textvalue"];
[alert show];
UIAlertController
UIAlertController *alert = [UIAlertController
alertControllerWithTitle:#"sample"
message:#" "
preferredStyle:UIAlertControllerStyleAlert];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField)
{
[textField setText:#"Richard"];
textField.placeholder = NSLocalizedString(#"textvalue", #"Login");
}];
[alert addAction:[UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
// do your action on ok click
}]];
[alert addAction:[UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
// do your action on cancel click
}]];
UIViewController *viewController = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
if ( viewController.presentedViewController && !viewController.presentedViewController.isBeingDismissed ) {
viewController = viewController.presentedViewController;
}
NSLayoutConstraint *constraint = [NSLayoutConstraint constraintWithItem:alert.view attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationLessThanOrEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1 constant:viewController.view.frame.size.height*2.0f];
[alert.view addConstraint:constraint];
[viewController presentViewController:alert animated:YES completion:^{
}];

it is working 100%
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert" message:#"message" delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[[alert textFieldAtIndex:0] setText:[NSString stringWithFormat:#"%#", #"preloaded string"]];
[alert show];

you either need to create your own custom "popup" view that will look like UIAlertviewlike in here or use a open source implementation like SDCAlertView
what you can also do is to use UIAlertController (as UIAlertview is also deprecated in IOS 8)
UITextField *alert = alertController.textFields.firstObject;
[alert setText#"YOUR ALERT TEXT HERE"];
