How to add the Finish button to the keyboard?

Question

UPDATE:

I also tried implementing the UITextViewDelegate delegate, and then executed in my controller:

- (BOOL)textViewShouldEndEditing:(UITextView *)textView { [textView resignFirstResponder]; return YES; } 

I also assigned a delegate to the text view self (controller instance).

Pressing the "Finish" button still inserts only a new line: (

---

UPDATE:

What I have done so far. I executed UITextFieldDelegate using my view controller.

I connected the text view to the view controller through the output.

Then I did:

---

 self.myTextView.delegate = self; 

and

 - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return YES; } 

But when I click Finish, it just adds a new line.

So, I have a UITextView element in my scene, and when the user picks it up, a keyboard appears and can be edited.

However, I cannot remove the keyboard.

How can I add a Done button to the keyboard so that it can be rejected?

Answer 1

It's pretty simple :)

 [textField setReturnKeyType:UIReturnKeyDone]; 

to reject the keyboard implements the <UITextFieldDelegate> protocol in your class, set

 textfield.delegate = self; 

and use

 - (void)textFieldDidEndEditing:(UITextField *)textField { [textField resignFirstResponder]; } 

or

 - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return YES; } 

Answer 2

Go to your storyboard, select your text box, and the "return key" option will appear in the "Attributes inspector" section ... select "Done".

Then go to your ViewController and add:

 - (IBAction)dismissKeyboard:(id)sender; { [textField becomeFirstResponder]; [textField resignFirstResponder]; } 

Then go back to your text box, click the exits and the "Finished on Exit" link to cancel the Keyboard action.

Add a UIToolBar as a custom view that will have a Done button as a UIBarButtonItem.

This is a safer and cleaner way to add a Finish button to any type of keyboard. Create a UIToolBar by adding a Done button to it and set the inputAccessoryView of any UITextField or UITextView.

 UIToolbar *ViewForDoneButtonOnKeyboard = [[UIToolbar alloc] init]; [ViewForDoneButtonOnKeyboard sizeToFit]; UIBarButtonItem *btnDoneOnKeyboard = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(doneBtnFromKeyboardClicked:)]; [ViewForDoneButtonOnKeyboard setItems:[NSArray arrayWithObjects:btnDoneOnKeyboard, nil]]; myTextField.inputAccessoryView = ViewForDoneButtonOnKeyboard; 

IBAction for the Finish button

  - (IBAction)doneBtnFromKeyboardClicked:(id)sender { NSLog(@"Done Button Clicked."); //Hide Keyboard by endEditing or Anything you want. [self.view endEditing:YES]; } 

SWIFT 3

 var ViewForDoneButtonOnKeyboard = UIToolbar() ViewForDoneButtonOnKeyboard.sizeToFit() var btnDoneOnKeyboard = UIBarButtonItem(title: "Done", style: .bordered, target: self, action: #selector(self.doneBtnFromKeyboardClicked)) ViewForDoneButtonOnKeyboard.items = [btnDoneOnKeyboard] myTextField.inputAccessoryView = ViewForDoneButtonOnKeyboard 

Function

  @IBAction func doneBtnFromKeyboardClicked (sender: Any) { print("Done Button Clicked.") //Hide Keyboard by endEditing or Anything you want. self.view.endEditing(true) } 

Answer 4

Quick version:

In your ViewController:

 textField.returnKeyType = UIReturnKeyType.Done textField.delegate = self 

After viewing the ViewController

 extension MyViewController: UITextFieldDelegate { func textFieldShouldReturn(textField: UITextField) -> Bool { textField.resignFirstResponder() return true } } 

Answer 5

Set the 'Return Key' option in the text field parameter in the inspector for the text field. Then right-click the text field and holding CTRL , select 'Did End On Exit' and drag it into the view controllers file. This will create an IBAction method. Give the method a name and enter the following values:

 [textField becomeFirstResponder]; [textField resignFirstResponder]; 

Your method should look like this:

 - (IBAction)methodName:(id)sender; { [sender becomeFirstResponder]; [sender resignFirstResponder]; } 

Answer 6

Good, that's why I am also struggling with this very problem. I am currently accessing a UITextView in a UITableViewCell (via tags). Since I use prototypes, I cannot use IBActions or IBOutlets, as everyone says. Instead, I use:

- (BOOL) textView: (UITextView *) textView shouldChangeTextInRange: (NSRange) range replacementText: (NSString *) text

This will then give me text every time the user clicks a button. Then my solution was to get the ascii character for a new line; "/P". If this is the text that was entered, I will set aside the first responder. For example:

 // If the text length is 0 then the user is deleting something, so only check the ascii character if there is text to check if (text.length != 0) { // Get the Ascii character int asciiCode = [text characterAtIndex:0]; // If the ascii code is /n or new line, then resign first responder if (asciiCode == 10) { [alertTextView resignFirstResponder]; [DeviceTextView resignFirstResponder]; } } 

Not sure if anyone else will need this hacker solution, but I thought I put it there if someone needs it!

Answer 7

This is the best way to add the Finish button on your keyboard.

 textField.returnKeyType = UIReturnKeyDone; 

Answer 8

In Interface Builder, you can set the type of the return button to Done using the textView properties.

Then you need to check if the back button is pressed with

  - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text 

Check if the text == "/ n", then release the keyboard by canceling the first responder on your text element.
