UITextView : How to hide keyboard

yourUITextView.resignFirstResponder will cause the keyboard to disappear if your text view was the first responder.

Or you can probably call yourUITextView.editable = NO to prevent any text entry in the view.

I'm sorry but that was not a very good answer. Of course you resignFirstResponder. The problem is what event is used to trigger this? The return button simply goes to the next line.

I thought it was actually a good response. There are tons of events you can use to trigger it ... you can't expect every single event to be listed.

How about looking at some of the events on the text field? That would be a good place to start. And if you read the overview of UITextField it +tells you explicitly how to do this+.

Ok here they are:

– textViewShouldBeginEditing:
– textViewDidBeginEditing:
– textViewShouldEndEditing:
– textViewDidEndEditing:
– textView:shouldChangeTextInRange:replacementText:
– textViewDidChange:
– textViewDidChangeSelection:

None of these will trigger when the user hits return. The first four trigger based on being assigned or resigned as the First responder and the last three trigger based on individual changes.

Did you read the overview of UITextField?

Yes. I need a UITextView though. Need multi-line and I need to be able to determine cursor location. Both these functions are available only under UITextView and not UITextField.

I don't know if this will work for you, but what I do in

textView:shouldChangeTextInRange:replacementText:

is check for [text isEqualToString:@"\n"] and then resign first responder. I'm using the standard keyboard, so in my case the "Done" key does induce this message, delivering @"\n".

Hope this helps,
Doug

@dredmuns: thanks, it worked perfectly!

I'm having trouble with this. Can you give sample code of what it should look like?

Thanks for advice about looking for the carriage return. Here is my contribution. The UITextViewDelegate (which will be your custom subclass of a UIViewController) will implement this method.

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if(text isEqualToString:@"\n")
{
self.textView resignFirstResponder;
return NO;
}
return YES;
}

The forum will not format the code correctly but anyway, hope you get the gist

Maybe in the view controller implementation you can code as follows (of course change names to best fit your actual objects):

-(BOOL)textFieldShouldReturn:(UITextField *)theTextField{
if (nome==theTextField){
[nome resignFirstResponder];
}
return YES;

and of course in the header file declare something like this:

@interface testViewController : UIViewController <UITextFieldDelegate>

Hope this helps

(not sure about the forum formatting, hope you can figure out the right format anyway)

uh, forgot a closing!
this is the right one:

-(BOOL)textFieldShouldReturn:(UITextField *)theTextField{
if (nome==theTextField){
[nome resignFirstResponder];
}
return YES;
}

the thing is, he is asking about the TextView, not the TextField! TextView's done button does NOT invoke the ShouldReturn delegate method
