AlertViewController
// use UIAlertController
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"Title"
message:#"SubTitle"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action){
//Do Some action here
UITextField *textField = alert.textFields[0];
NSLog(#"text was %#", textField.text);
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
NSLog(#"cancel btn");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = #"placeHolderText";
textField.keyboardType = UIKeyboardTypeDefault;
}];
[self presentViewController:alert animated:YES completion:nil];
UIAlertView
UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:#"Title"
message:#"SubTitle"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
[dialog show];
}

Example of implementation with Swift 3:
var textField: UITextField?
// create alertController
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)
alertController.addTextField { (pTextField) in
pTextField.placeholder = "usefull placeholdr"
pTextField.clearButtonMode = .whileEditing
pTextField.borderStyle = .none
textField = pTextField
}
// create cancel button
alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (pAction) in
alertController.dismiss(animated: true, completion: nil)
}))
// create Ok button
alertController.addAction(UIAlertAction(title: "OK", style: .default, handler: { (pAction) in
// when user taps OK, you get your value here
let inputValue = textField?.text
alertController.dismiss(animated: true, completion: nil)
}))
// show alert controller
self.present(alertController, animated: true, completion: nil)

UIAlertView *myView = [[UIAlertView alloc]initWithTitle:#"Input" message:#"Enter your value" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
myView.alertViewStyle = UIAlertViewStylePlainTextInput;
[myView textFieldAtIndex:0].delegate = self;
[myView show];
you can cover this way .Thanks

Answer 5

UIAlertView *av = [[UIAlertView alloc]initWithTitle:#"Title" message:#"Please enter someth" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av textFieldAtIndex:0].delegate = self;
[av show];
also, you will need to implement UITextFieldDelegate, UIAlertViewDelegate protocols.
and if you user uialertcontroller then use this one
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"My Title"
message:#"Enter User Credentials"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//Do Some action here
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = #"Username";
}];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = #"Password";
textField.secureTextEntry = YES;
}];
[self presentViewController:alert animated:YES completion:nil];

Here's handy method with submit/cancel and completion handler for text if inputted:
/**
Presents an alert controller with a single text field for user input
- parameters:
- title: Alert title
- message: Alert message
- placeholder: Placeholder for textfield
- completion: Returned user input
*/
func showSubmitTextFieldAlert(title: String,
message: String,
placeholder: String,
completion: #escaping (_ userInput: String?) -> Void) {
let alertController = UIAlertController(title: title,
message: message,
preferredStyle: .alert)
alertController.addTextField { (textField) in
textField.placeholder = placeholder
textField.clearButtonMode = .whileEditing
}
let submitAction = UIAlertAction(title: "Submit", style: .default) { (action) in
let userInput = alertController.textFields?.first?.text
completion(userInput)
}
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (_) in
completion(nil)
}
alertController.addAction(submitAction)
alertController.addAction(cancelAction)
present(alertController, animated: true)
}

This one is work for me:
let passwordString = lableGetPassword.text
var textField: UITextField?
// create alertController
let alertController = UIAlertController(title: "Password", message: "Save the password. Give a tag name.", preferredStyle: .alert)
alertController.addTextField { (pTextField) in
pTextField.placeholder = "Tag Name"
pTextField.clearButtonMode = .whileEditing
pTextField.borderStyle = .none
textField = pTextField
}
// create cancel button
alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (pAction) in
alertController.dismiss(animated: true, completion: nil)
}))
// create Ok button
alertController.addAction(UIAlertAction(title: "Save", style: .default, handler: { [self] (pAction) in
// when user taps OK, you get your value here
let name = textField?.text
save(name: name!, password: passwordString!)
alertController.dismiss(animated: true, completion: nil)
}))
// show alert controller
self.present(alertController, animated: true, completion: nil)
