Как изменить изображение моего изображения, когда я нажимаю кнопку «Готово», изображение будет меняться при первом просмотре?

Question

Как изменить изображение изображения моего профиля, когда я нажимаю кнопку «Готово» на втором экране, первое изображение на экране должно меняться со вторым изображением экрана. Я выбираю изображение из галереи, что изображение появилось на моем втором экране, как установить это изображение в первом экране контроллера экрана, пока я нажимаю кнопку «Готово».

Answer 1

// if([_delegate respondsToSelector:@selector(imageSelected:)]) { // [self.delegate imageSelected:imageView]; }

Этот код является технически корректным. Но вы забыли синтезировать своего делегата в AddprofileViewController
