I would like to know how to DISABLE (not how to dismiss) the iOS keyboard in a TextView. I don`t even want the keyboard to show up when the user touches the TextView.
All of the examples I found were to make the keyboard disappear AFTER it appears.
The closest thing I got was to set textView.userInteractionEnabled = NO; but that gets rid of the scrolling as well (I want to keep the scrolling).
Thank you in advance!!
Try to implement the following method in text view's delegate:
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{
return NO;
}

There is a requirement of inputAccessoryView is for the chat application.
When I add inputAccessoryView to UITextField on tap event of UIButton. That view is set as inputAccessoryView completely but text field is not becoming first responder.
(Note: Super view of textfield is viewText.)
- (IBAction)btnOpenTextField:(id)sender
{
UIView *accessoryView=[[UIView alloc]init];
accessoryView.frame=CGRectMake(0,0, _viewText.frame.size.width, _viewText.frame.size.height);
[accessoryView addSubview:_viewText];
_txtMessage.inputAccessoryView = accessoryView;
[_txtMessage becomeFirstResponder];
}
Thanks in Advance.
You can call [_textMessage reloadInputViews], replacing [_text becomeFirstResponder].
What you want to achieve is quite not possible, this will cause recursion, alternatively what you can do is put a textfield on bottom of the screen and when the textfield is selected you can animate it up with the flow of the keyboard. i think this is an appropriate solution if i got your question correctly.
Can anyone think of a reason that a UITextField would resignFirstResponder, and then no longer respond to touches to becomeFirstResponder? I have a situation where I have a view controller that appears, but the keyboard disappears immediately, and the text field still has the cursor, but it's not blinking. Tapping on the text field will cause the "paste" menu option to appear and I can paste text into the field, but I cannot make it become first responder.
Any thoughts would be greatly appreciated...
I've had to deliberately create this scenario before for a previous app and the way i did it was to set the input view for the textfield to a tiny dummy view.
UIView* view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
myTextField.inputView = view;
Although I believe this still showed the blinking cursor.
To get the blinking cursor to stop as well I had to return NO in the shouldBeginEditing method.
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
return NO;
}
So if you are doing either of these things you would get the behaviour that you're currently experiencing where the textfield is actually responding but it is isn't showing a keyboard or a blinking cursor.
I have an issue with a resizing UITextView
It resizes correctly when user is typing and resizes incorrectly, when i set its text programmatically
with [textView setText:]
I want to set its text to blank by doing setText:#"" and then clicking the spacebar programmatically
How do i click the space bar programmatically ?
Here are screenshots of my problem
More than likely you've put code in (void)textViewDidChange:(UITextView *)textView that doesn't belong there.
The text view calls this method in response to user-initiated changes
to the text. This method is not called in response to programmatically
initiated changes.
The solution is to create a separate method that runs regardless of whether the text was changed programmatically or by the user. It will probably looks something like this.
- (void)setText:(NSString *)text {
self.myTextView.text = text;
[self updateTextViewSize];
}
- (void)textViewDidChange:(UITextView *)textView {
[self updateTextViewSize];
}
- (void)updateTextViewSize {
//sizing logic goes here
}
I'm trying to achieve a similar keyboard interaction that Messages has in iOS 7. I have a UIView which contains a UITextView, and when the user selects it to start typing, I want to make this UIView the inputAccessoryView. This would take care of the animation for me, as well as the new UIScrollView keyboard dismiss interaction in iOS 7.
When the UITextView begins editing, I'm trying to set its inputAccessoryView to its parent UIView (which is already in the view hierarchy). The keyboard appears but not with an accessory view.
I've read some people are using a duo of UITextFields to make this work, but that seems like a bad way to achieve this.
Any suggestions?
A much easier solution is to make your input field the input accessory view of your view controller:
- (BOOL)canBecomeFirstResponder
{
return YES;
}
- (UIView *)inputAccessoryView
{
return self.yourInputField;
}
The view will be on screen at the bottom of the screen and when it becomes first responder in response to a user tapping it, the keyboard will be presented. The view will be animated such that it remains immediately above the keyboard.
The only way to get this to work is via a second text field. The idea is to make it a subview but not visible (due to crazy rect). You then switch firstResponder back and forth between it and the real text field while its getting delegate methods. I created a some one viewController test project and did this (you can copy paste and verify behavior with about 2 minutes of time):
#implementation ViewController
{
UITextField *field;
UITextField *dummyView;
}
- (void)viewDidLoad
{
[super viewDidLoad];
field = [[UITextField alloc] initWithFrame:CGRectMake(0, 460, 320, 20)];
field.borderStyle = UITextBorderStyleRoundedRect;
field.delegate = self;
//field.inputAccessoryView = field;
field.text = #"FOO";
[self.view addSubview:field];
dummyView = [[UITextField alloc] initWithFrame:CGRectMake(0, 40000, 320, 20)];
dummyView.delegate = self;
[self.view addSubview:dummyView];
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if(textField == field && textField.superview == self.view) {
[field removeFromSuperview];
dummyView.inputAccessoryView = field;
[dummyView becomeFirstResponder];
}
return YES;
}
#end
I should add I've used this technique in shipping apps since iOS 4.
EDIT: So a couple of other ideas:
1) To make the glitch when the keyboard starts moving look a little better, you could take a snapshot of your textView, put that into a UIImageView, and when you remove the textView from the primary view, replace it with the UIImageView. Now the appearance is the same. Add an animation for the image so that noting happens for 50 ms, then the alpha goes to 0. Add a similar animation to your real textview, so that it has an alpha of 0 for 50 ms, then it goes to 1. You may be able to tweak this so the transition is good (but not great).
2) The way apple probably does this is to get the animation curve and timing from the keyboard moving notification. In this case they would add a accessory view with 0 height at first, and animate the textField so its tracking the keyboard, but above it. Both moving same distance at the same time. At the end of the animation, the textField is pulled out of self.view, the accessory view has its frame changed to have the height of the textField, and the textField is placed as a subview of the accessory container view. This should work but yeah, its a bit complex to do. If you want someone to code it for you offer a 100 pt bounty. You still need the dummy text field for when you go and move the textField at the end, since when you take it out of its containing view it will resign first responder. So at the end, you make the dummy field the first responder, move the textfield, then make the real textfield the first responder again.
This actually works best if you don't use .inputAccessoryView at all and instead just animate the position of the parent UIView as the keyboard opens and closes. Here is an answer describing the process step-by-step with all the code.
In my IPad Application i am using TextView only for Text Displaying.As i need to display a Larger Text Thats Why i am using UITextview due to its Scrolling Property instead of using UILabel.
In my application i do not need to edit Text in UITextview ,but problem for me is that when i click on Textview for scrolling the keyboard appear its hide my textview so i want that my keyboard is never appear on click event.i make a search but not find any Suitable solution.Any help will be appriated.Thanx
NEW ANSWER (previous one was not working properly)
OK so since that is not working because it disables scrolling also, you should try to:
Implement UITextFieldDelegate protocol
In your view controller add the text
#interface YourViewController () <UITextViewDelegate>
In viewDidLoad set yourself as a delegate:
yourUITextView.delegate = self;
Implement the delegate method below:
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
return NO;
}
When the textview is about to edit the text, this method will be called automatically. It returns no, so the editing won't start.
It is very important that you undo the changes from the previous answers: Do not set the editable field to NO
I tried it and it's working. Hope it helps!
OLD ANSWER
when you declare the variable, or in your viewdidload method, set the editable property to NO:
yourUITextView.editable = NO;
or
[yourUITextView setEditable:NO]
That should prevent the keyboard from appearing.
Go to .XIB file and you can uncheck behavior editable or programmatically
textView.editable = NO;
