Вопрос:
По сути, я создал приложение для звуковой панели из другого приложения. Однако я продолжаю получать ту же ошибку, и я не могу понять, что не так. Я совсем новичок в xcode и искал помощь по всему Интернету. Я опубликую всю информацию, которая может потребоваться, и, надеюсь, смогу заставить это работать.

Ответ №1:
Видите это сообщение об ошибке?
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0
Теперь посмотрите на все IBAction методы, которые вы перечислили ( -pushAbout и т.д.).
Вы заметите, что -pushBetter среди них нет.
Вам нужно написать -pushBetter метод и подключить его к UIButton .
Ответ №2:
Похоже, вы каким-то образом отправляете вызов метода pushBetter на ваш контроллер просмотра, к которому он, по-видимому, не подготовлен (согласно вашему коду и ошибке):
-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0'
Можете ли вы выполнить глобальный поиск по «pushBetter» и посмотреть, где он находится в вашем проекте??
