I have a custom text view I made using CoreText which implements UITextInput to handle multi stage input on Japanese and Chinese keyboards. I'm trying to limit the number of characters that can be typed into the text view using shouldChangeTextInRange:replacementText: and I'm noticing that it's only called when a key on the keyboard is pushed, but not when a button on the thing above the keyboard which offers replacement suggestions is pushed (example below).
Does anyone know why this is and if there are any similar methods I can implement that will be called when a suggestion above the keyboard is pushed (so I can block them from being set as marked text)?

I have created a custom accessory view to supplement the standard Apple alpha iOS keyboard.
The purpose is to add a line of numeric keys to prevent flipping back and forth between keyboard views. At first, I created a toolbar and loaded it with a set of 0 - 9 titled buttonItems and it functioned quite well. However, it looked terrible, not at all like the alpha keys despite adding a rounded rect background image to each key because the system apparently prevents customizing font size and button spacing inside the stack view of the toolbar. Therefore, I created a UIView xib and loaded it with a stackView full of customized numerical buttons. When I add the UIView as the accessory view it looks pretty darn close to the rest of the Apple Alpha keyboard. The issue now is that the touch-up events go to the UIView class of the accessory view. Is there a clever, efficient way to have the button presses in the accessory emulate the std keyboard feeding into TextField: shouldChangeCharactersIn? I could package the button presses into a local notification event to get it into the class holding the textField but that seems terribly inelegant! Any suggestions would be greatly appreciated. Stay Safe!
Not the best answer, but I did implement notification on key button press with an observer in the main view class. The observer does a TextField.insertText which is suboptimal since I will need to refactor the several hundred lines of code that performs real-time language translation in the shouldChangeCharacters methods. Ah well.
I'm having an issue. I am using the Hakawai framework in an app so that I can have mention support (#username).
The issue I've run into is that the textfield I am using is not registering the case where there is no text and a user types an emoji into the textview. As we are using HKWTextView, I believe the textViewShouldChangeTextInRange delegate method is never called, even if implemented. The only replacement I can think to use is :
- (void)textView:(HKWTextView *)textView didChangeAttributedTextTo:(NSAttributedString *)newText
originalText:(NSAttributedString *)originalText
originalRange:(NSRange)originalRange;
in HKWTextView, but that's still not picking up on emojis being typed in when no other text has.
The functionality I would like is:
- Text view is empty
- user types in anything, emoji included
- textview width shortens, "Post" button appears.
Right now, typing emojis into the empty text view will not make the post button appear. However, it's worth mentioning that once the emojis are typed in, if there is more than one, deleting one of them WILL make the post button appear. I'm at a bit of a loss here.
I found the answer to this - It turns out that HKWTextView does some rewiring of the UITextView delegate methods that are fired. Try handling the input in the UITextView delegate method textViewDidChangeSelection. That method will be fired when an emoji is typed.
I'm working on an iOS app using swift. I have a SearchBar/Textview (i've tried with both) and want to split each search term a user types in, into a bubble similar to pinterest where the user can later press the cross to remove certain ones.
How do I start with this? I can only seem to change the background of the whole TextField instead of just for each word.
Here's a sample of what I am trying to achieve.

This is not really a formatted text. What they are doing is different. When a space/enter is typed in (and you can detect that by the UITextField delegate), you take the currently written text and create a view from it.
The structure of that view will be similar to the following:
+ view
+ label with the text
+ x (remove) button
You will then add this view to a container view. The purpose of this view is to keep the search term views in a list.
You can then assign this container view to [UITextField leftView].
Of course, then you have to handle removal, backspace etc.
I have developed an IOS 8 custom keyboard. I want to give it "undo" and "redo" functionality, like the default system keyboard. I have tried it in different ways but was unable to find a good solution.
We can interact with a Text Input Object textDocumentProxy with the methods
insertText
deleteBackward
documentContextAfterInput
ocumentContextBeforeInput
But I was unable to find any way of implementing "undo" and "redo" functionality.
I think we can NOT implement these function (undo,redo)
According to https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/Keyboard.html
Because a custom keyboard can draw only within the primary view of its
UIInputViewController object, it cannot select text. Text selection is
under the control of the app that is using the keyboard. If that app
provides an editing menu interface (such as for Cut, Copy, and Paste),
the keyboard has no access to it. A custom keyboard cannot offer
inline autocorrection controls near the insertion point.
I think there are many case that content of textfield changed and you can not know when it changed, how it changed. If we can not know, we can not know to undo to where too. I think so.
I'm developing Custom keyboard extension like you and I have many problems. (eg: how can we know the current cursor to get current text selection...)
My question: Current text selection in CustomKeyBoardExtension (hope somebody know)
Has anyone run across this warning message building for the iPhone?
More importantly do you understand how to fix it?
"unsupported configuration data detection and editable"
It's seems to be the UITextView that is complaining.
Here's a screenshot.
The problem is that you have that textview set both to editable + to detect/autolink phone numbers, events, addresses, etc. a text area can either be editable and not detect/autolink text, or it can autolink text but not be editable.
Your settings for that textview should look like:
or
but not like:
I think in your scenario, the text input is only used to input text, nothing more. Then when it get's presented back, the "presenting text view" will take care of detecting the potential information... dates, events, etc.
To be more precise : in a simple app scenario, a user types in some text (let's say an event input text view - with no detection necessary at this point). Then when it get's eventually presented back to him or another user (let's say the detail view of the event), the text will be presented back in a "non-editable" text view that in turn will be able to have detections.
I know this question is a little old, but this is how I resolved it;
In Interface Builder I have Links Detection selected, and Editable Behaviour not selected.
Then, in my ViewController, I implemented the UITextView - (BOOL)textViewShouldBeginEditing:(UITextView *)textView { } delegate method and return NO.
It removed the warning and prevents the user from being able to edit the UITextView's content.
