Xcode ulega awarii po wybraniu karty w panelu kolorów

Question

Mam do czynienia z tym dziwnym problemem od kilku godzin i zaczęło się nagle. Ilekroć próbuję wybrać inną zakładkę w panelu kolorów w Xcode, cała Xcode wywala się z błędem,

UNCAUGHT EXCEPTION (NSRangeException): Cannot remove an observer <NSColorPickerPageableNameListScrollView 0x7fb8f6ce0910> for the key path "contentLayoutRect" from <HighlightColorPanel 0x7fb8f6c94af0> because it is not registered as an observer. 

Poniżej znajduje się pełny ślad stosu błędu,

Dziękuję bardzo z góry .

Answer 1

W moim przypadku dokładnie ten sam problem został spowodowany przez wtyczkę ColorSenseRainbow zainstalowaną przez Alcatraz. Jak tylko ją usunąłem, wszystko wróciło do normy.

Answer 2

Wydaje się, że jest to problem ze strony Apple. Pozwól mi strawić ten dziennik dla Ciebie:

UNCAUGHT EXCEPTION: Cannot remove an observer <NSColorPickerPageableNameListScrollView 0x7fb8f6ce0910> for the key path "contentLayoutRect" from <HighlightColorPanel 0x7fb8f6c94af0> because it is not registered as an observer.

Więc w kodzie Xcode, co próbuje zrobić, to usunąć obserwatora, który jest typu NSColorPickerPagableNameListScrollView (w górę/w dół listy wybiera preferencje kolorów dewelopera w IB) pod adresem pamięci 0x7b7f6ce0910 z HighlightColorPanel (prawdopodobnie okno dialogowe, które jest próbnikiem kolorów) pod adresem pamięci 0x7fb8f6c94af0, zanim widok przewijania zostanie zarejestrowany jako obserwator próbnika kolorów dla ścieżki klucza contentLayoutRect.

W kategoriach laika, przewijany widok kolorów to , obserwator selektora kolorów, co ułatwia dostrzeżenie preferencji kolorów. Gdy selektor kolorów wybierze kolor, wysyła do swojego obserwatora okno przewijania kolorów.

Jednak, gdy okno jest zamknięte, widok przewijania powinien usunąć się z drzewa obserwatora, czyli listę przedmiotów, które są obserwatorzy z pudełka, starając się pozbyć (i deallocate zasobów dla) pola.

Błąd występuje tylko w tej części kodu, ponieważ najwyraźniej widok przewijania nigdy nie został zarejestrowany jako obserwator dla ścieżki klucza contentLayoutRect. Był to obserwator dla wszystkich pozostałych , ale, że. Ponieważ nie mógł powiedzieć, co obserwator był, gdy próbował się go pozbyć, system wyskakiwał i rozbił się.
