Я хочу добавить ввод текста в alert-view ios 8.
Я знаю, что это было сделано с помощью UIAlertController
, но у меня нет никакой идеи.
Как это сделать?

код
UIAlertController * alertController = [UIAlertController alertControllerWithTitle: @"Login"
message: @"Input username and password"
preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = @"name";
textField.textColor = [UIColor blueColor];
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];
вы можете покрыть этот путь. Спасибо

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];
}

Пример реализации с 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 *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];
вам также потребуется реализовать UITextFieldDelegate, протоколы UIAlertViewDelegate.
и если вы используете uialertcontroller, то используйте этот
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];

UIAlertViewController с текстовым вводом
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title"
message:nil
preferredStyle:UIAlertControllerStyleAlert];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
// optionally configure the text field
textField.keyboardType = UIKeyboardTypeAlphabet;
}];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action) {
UITextField *textField = [alert.textFields firstObject];
textField.placeholder = @"Enter Input";
}];
[alert addAction:okAction];
[self presentViewController:alert animated:YES completion:nil];
