iPhone Programming: Deactivate spell check in UITextView

Question

UITextAutocorrectionTypeNo didn\'t work for me.

I\'m working on a crossword app for the iPhone. The questions are in UITextViews and I use UITextFields for the User-

Answer 1

I had the same problem. The solution is very simple but not documented: You can only change the properties defined in the UITextInputTraits protocol while the UITextView in question is NOT the first responder. The following lines fixed it for me:

[self.textView resignFirstResponder];
self.textView.autocorrectionType = UITextAutocorrectionTypeNo;
[self.textView becomeFirstResponder];

Hope this helps somebody.

Answer 2

One potentially-helpful tip following from Engin Kurutepe's answer:

If you have subclassed UITextView, you can override the UITextInputTraits in the subclass implementation of becomeFirstResponder, something like this:

-(BOOL)becomeFirstResponder {
    self.spellCheckingType = UITextSpellCheckingTypeNo;
    self.autocorrectionType = UITextAutocorrectionTypeNo;
    self.autocapitalizationType = UITextAutocapitalizationTypeNone;
    return [super becomeFirstResponder];
}

There is then no need to explicitly resign/becomeFirstResponder around your trait changes.

Got a solution but it's not really how it should be. If someone knows something better, please tell me.

The autocorrection executes, after the first touche. So I alloc a new UITextView and set him like the touched TextView. Then I replace the touched textView with my new TextView. So every UITextView instance could only be touched once and disappears. :)

//UITextView delegate method in my Riddle-Class

-(BOOL)textViewShouldBeginEditing:(UITextView *)textView {

    ...CODE FROM FIRST POST HERE...

    // ADDED CODE:
    for (int i = 0; i < [textViews count]; i++) {
        if (textView == [textViews objectAtIndex:i]) {
            UITextView *trickyTextView = [[UITextView alloc] initWithFrame:textView.frame];
            trickyTextView.text = textView.text;
            trickyTextView.font = textView.font;
            trickyTextView.autocorrectionType = UITextAutocorrectionTypeNo;
            trickyTextView.textColor = textView.textColor;
            trickyTextView.backgroundColor = textView.backgroundColor;
            trickyTextView.delegate = self;
            trickyTextView.scrollEnabled = NO;
            [textViews replaceObjectAtIndex:i withObject:trickyTextView];
            [textView removeFromSuperview];
            [zoomView addSubview:trickyTextView];
            [trickyTextView release];
            break;
        }
    }
    return NO;
}

Important

Disabling spell check will NOT update the UI of the red-line until the text itself is also updated. Simply setting the spellCheck to NO is not enough.

To force a UI update, set the spellcheck property to NO, then toggle the text blank then back, like so:

_textView.spellCheckingType = UITextSpellCheckingTypeNo;

NSString *currentText = _textView.text;
NSAttributedString *currentAttributedText = _textView.attributedText;
_textView.text = @"";
_textView.attributedText = [NSAttributedString new];
_textView.text = currentText;
if (currentAttributedText.length > 0) {
    _textView.attributedText = currentAttributedText;
}
