I need to use two different fonts in text view, so I set attributed Text in textViewDidChange. But for Japanese keyboard the input character is entered repeatedly.
It works for English keyboard. It also works for Japanese keyboard when you use normal text instead of attributedText.
My code:
- (void)viewDidLoad {
[super viewDidLoad];
UITextView *textView = [[UITextView alloc] initWithFrame:self.view.frame];
textView.delegate = self;
[self.view addSubview:textView];
}
- (void)textViewDidChange:(UITextView *)textView
{
NSLog(@"TOTAL: %@", textView.text);
textView.attributedText = [[NSMutableAttributedString alloc] initWithString: textView.text];
}
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
NSLog(@"ADDED: %@", text);
return YES;
}
Output:

2015-07-15 13:51:10.167 japKeyTest[32163:5765000] TOTAL: あ

Any idea how to enter attributed text with Japanese keyboard and get normal result? (without extra characters)

UITextView supports the display of text using custom style information and also supports text editing. You typically use a text view to display multiple lines of text, such as when displaying the body of a large text document. This class supports multiple text styles through use of the attributedText property.
We shall utilise the Delegate feature so the view, as the delegate to the UITextFields and UITextViews, can control the impact of the keyboard display on the positions of UITextFields and UITextViews.

// Resign the first responder from textField to close the keyboard. To hide the keyboard when the user presses the return key on UITextView ‘s keyboard. We can add the below code in the textView function. You should first make your ViewController class implement the UITextViewDelegate delegate protocol.
This answer helped me figure it out: Check if markedTextRange on the UITextView is not nil. This means that the user is in the middle of inputting a multistage character. Hold off on editing the attributedText until they are done.
