• (NSString *)textInRange:(UITextRange *)range
  {
  CCLOG("textInRange");
  if (nil != markedText_) {
  return markedText_;
  }
  return @"";
  }

• (UITextRange *)markedTextRange

  CCLOG("markedTextRange");

* (NSString *)textInRange:(UITextRange *)range
  {
  CCLOG("textInRange");
  if (nil != markedText_) {
  return markedText_;
  }
  return @"";
  }

* (UITextRange *)markedTextRange
  {
  CCLOG("markedTextRange");
  if (nil != markedText_) {

I have tried this code. The input of Chinese is ok. But when i click the screen to close IME. The IME open again. I debug this performance and find i recieved UIKeyboardWillShowNotification.

I don't know what's the problem, i can input Chinese characters with iPhone11(iOS 13).

[lxhhuangjin]

My iPhone X(iOS13) input Chinese in
TextField has problem. The function named setMarkedText just received one charactor I input recently.

[minggo]

What test case did you test?

[lxhhuangjin]

What test case did you test?

Any input is ok.
eg. First i input 'w', setMarkedText recieved 'w', then input 'd', setMarkedText recieved 'd'. But setMarkedText need recieve 'wd'.

[minggo]

Did you use TextFieldTTF? Please show your test case and the steps to reproduce it. Thanks.

[lxhhuangjin]

Yes. I use TextFieldTTF for input.
I want to input Chinese like "我的" on iPhone.
So i input 'wd' for the words. But the input result is not correct. The result did not change compared with the input when i open IME.
I debuged for this problem. I fond the problem is the function or setMarkedText.
I think you can reproduce this problem by any iPhone when update to iOS 13. I tried iPhoneXR and iPhoneXS Max.

[minggo]

As i said above, i tested TextInput and change to use Arial, then can input Chinese. You should check your ttf file support Chinese characters.

I can input Chinese properly before i update my iPhone to iOS 13.

[minggo]

I tested on iPhone11 with iOS13.

[minggo]

I tried iPhone8 with iOS 13, can reproduce it.

I tried the code of @wandeli and the problem has been resolved. But when i close the IME and touch screen where do not have textfield, the IME opened. This is another problem. But i think his code is a correct direction for this problem.

[minggo]

It is because engine can not receive touches end event, but i don't know why. If don't modify markedTextRange , then can just input a character a time.
