UITextView autocapitalization is not working when keyboard is active

Question

Currently, I am setting autocapitalization in a button target like this

//This method is fired when keyboard is still active
- (IBAction)changeAutoCapitalization:(id)sender
{   
      self.textView.autocapitalizationType = UITextAutocapitalizationTypeWords;
}

But this won't make keyboard to capital.

It just auto change the first character of sentence typed in your textview to capital character. It does not change the look of the keyboard (except when you start new sentence, the shift button is ON). — Duyen-Hoa, Oct 21 '16 at 14:07
Use `UITextAutocapitalizationTypeAllCharacters` if you want to switch the keyboard to capital characters only. — Duyen-Hoa, Oct 21 '16 at 14:08
@Hoa I am setting this autoCapitalization property when keyboard is still active(Keyboard is visible) for that UITextView and it is not getting changed. — Nikhil Manapure, Oct 21 '16 at 14:13
ah ok, call `[self.textView reloadInputViews];` after having changed the autocapitalizationtype — Duyen-Hoa, Oct 21 '16 at 14:24
@Hoa It worked ! Thanks for the help. Please post it as an answer. — Nikhil Manapure, Oct 21 '16 at 14:36

You have to call [self.textView reloadInputViews] after modifying the UITextAutocapitalizationType in order to change keyboard immediately.

So frustrating that this isn't auto-called by the OS when autocapitalizationType is modified. Thank you! – Albert Renshaw Feb 29 '20 at 07:05

If you find that you're doing a lot of text-related customizations, it might be helpful to subclass UITextView, to keep the functionality encapsulated.

Note: If testing on the simulator, make sure you are using the Simulator's keyboard, by going to the menu: I/O -> Keyboard -> Toggle Software Keyboard

If you are adding text automatically, for instance in response to a button tap, and the shift key turns off, then you can use this pattern:

autocapitalizationType = .allCharacters //Activate shift key
autocorrectionType = .no //Don't show all-caps auto suggest
reloadInputViews() //Apply changes

Then, to restore to sentences capitalization, for instance when a line is cleared:

if (autocapitalizationType = .allcharacters) {
    autocapitalizationType = .sentences //Activate sentence capitalization
    autocorrectionType = .yes //Show auto suggest
    reloadInputViews() //Apply changes
}

Other capitalization options:

.none
.words

You may also need to do this when any non-enter key is pressed. To do so, override insertText from UIKeyInput, and check the entered text string:

if (text != "\n") {
    if (autocapitalizationType == .allCharacters) {
        autocapitalizationType = .sentences //Activate sentence capitalization
        autocorrectionType = .yes //Show auto suggest
        reloadInputViews() //Apply changes
    }

    //Respond to any character sequences
    //...
}

Try to add this after initialization:

self.textView.autocapitalizationType = UITextAutocapitalizationTypeWords;

OR

It's very likely that the "Auto-Capitalization" option is turned off on that device. You can find that option in Settings > General > Keyboard.

In My case I was using 'Keyboard Type' as Name pad in storyboard.

Changing 'Keyboard Type' back to 'Default' resolved my issue.

Also added this code in viewDidLoad

textfieldCardName.autocapitalizationType = .allCharacters
