Kod

                        message: @"Input username and password" 
                       preferredStyle:UIAlertControllerStyleAlert];

     textField.clearButtonMode = UITextFieldViewModeWhileEditing; 
     textField.borderStyle = UITextBorderStyleRoundedRect; 
    }]; 
    [alertController addTextFieldWithConfigurationHandler:^(UITextField *textField) { 
     textField.placeholder = @"password"; 
     textField.textColor = [UIColor blueColor]; 
     textField.clearButtonMode = UITextFieldViewModeWhileEditing; 
     textField.borderStyle = UITextBorderStyleRoundedRect; 
     textField.secureTextEntry = YES; 
    }]; 
    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { 
     NSArray * textfields = alertController.textFields; 
     UITextField * namefield = textfields[0]; 
     UITextField * passwordfiled = textfields[1]; 
     NSLog(@"%@:%@",namefield.text,passwordfiled.text); 

    }]]; 
    [self presentViewController:alertController animated:YES 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]; 

można pokryć w ten sposób .Dzięki

Answer 3

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]; 

też, trzeba będzie wdrożyć UITe xtFieldDelegate, UIAlertViewDelegate protokołów.

a jeśli uialertcontroller użytkownik następnie użyć tego jeden

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];

Przykład realizacji z 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)

Oto przydatna metoda z przedstawienia/anulować i obsługi zakończenie tekstu, jeśli wprowadzane:

/** 
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) 
}
