Aplikacja Crash na iOS: ZL36GetSFTrimCharSetForChineseOrJapanesePPK9TFontInfo_block_invoke

Question

Znajduję w moim XCode "Organizer" błąd "ZL36GetSFTrimCharSetForChineseOrJapanesePPK9TFontInfo_block_invoke". Próbowałem ustawić iPhone'a w języku japońskim lub chińskim, ale błąd nie występuje. Co może być przyczyną tego błędu i jak mogę go rozwiązać? Przepraszam za mój zły angielski.

To dziennik katastrofy:

Wygląda obiekt został dealokowane nawet po referencję do tego obiektu, a więc kod zakłada, że ​​to ważne. Spróbuj uruchomić "Zombie" w Instrumentach. Pokaże ci, gdzie wysłałeś wiadomość do nieprawidłowego obiektu. Jeśli korzystasz z symulatora systemu iOS, spróbuj wykonać polecenie Sprzęt -> Symuluj ostrzeżenie o pamięci, tak często, jak to możliwe, próbując odtworzyć awarię.
