Disable UITextField keyboard shortcut suggestions - ios

Question

Is there a simple way to remove keyboard shortcut suggestions from a UITextField?
It is possible to remove typing correction with: [textField setAutocorrectionType:UITextAutocorrectionTypeNo]; however this as no effect on shortcuts.
Affecting the sharedMenuController also does not squash this.
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
[UIMenuController sharedMenuController].menuVisible = NO;
return NO;
}

Answer 1

Objective-C
textField.autocorrectionType = UITextAutocorrectionTypeNo;
Swift
textField.autocorrectionType = .no

Answer 2

Use this only
textField.autocorrectionType = UITextAutocorrectionTypeNo;

Answer 3

Solved this by implementing a UITextFieldDelegate method and manually setting the text property of UITextField.
By default in the simulator you can test this behaviour by typing "omw" which should suggest "On my way!". The following code will block this. Note: this does also disable auto-correction and check spelling which was ok in my case.
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
// Pass through backspace and character input
if (range.length > 0 && [string isEqualToString:#""]) {
textField.text = [textField.text substringToIndex:textField.text.length-1];
} else {
textField.text = [textField.text stringByAppendingString:string];
}
// Return NO to override default UITextField behaviors
return NO;
}

Answer 4

Matt's solution converted to Swift 5:
func textField(_ textField: UITextField,
shouldChangeCharactersIn range: NSRange,
replacementString string: String) -> Bool {
// Pass through backspace and character input
if (range.length > 0 && string.isEmpty) {
textField.text?.removeLast()
} else {
textField.text?.append(string)
}
// Return false to override default UITextField behaviors
return false
}

Answer 5

UITextField* f = [[UITextField alloc] init];
f.autocorrectionType = UITextAutocorrectionTypeNo;

Answer 6

The above mentioned answer may not work with cut / copy / paste situation. For example on cutting and pasting text in UITextField, the result is not as per default functionality.
Below is a similar approach:
-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
NSString *textFieldNewText = [textField.text stringByReplacingCharactersInRange:range withString:string];
if ([string isEqualToString:#""]) {
// return when something is being cut
return YES;
}
else
{
//set text field text
textField.text=textFieldNewText;
range.location=range.location+[string length];
range.length=0;
[self selectTextInTextField:textField range:range];
}
return NO;
}
//for handling cursor position when setting textfield text through code
- (void)selectTextInTextField:(UITextField *)textField range:(NSRange)range {
UITextPosition *from = [textField positionFromPosition:[textField beginningOfDocument] offset:range.location];
UITextPosition *to = [textField positionFromPosition:from offset:range.length];
[textField setSelectedTextRange:[textField textRangeFromPosition:from toPosition:to]];
}

Answer 7

textField.autocorrectionType = .No

Answer 8

Use AutocorrectionType :
[mailTextField setAutocorrectionType:UITextAutocorrectionTypeNo];

Answer 9

Swift 3.x or above:
textField.autocorrectionType = .no
