Расширение OpenFL для родной iOS (c ++, haxe, obj-c)

0

Я пытаюсь создать расширение, которое позволяет мне показывать предупреждающее сообщение с двумя кнопками в iOS с событиями handle:

У меня проблема с частью obj-c каждый раз, когда я пытаюсь скомпилировать:

Я потерялся здесь (заметьте, я не очень уверен в obj-c):

Сообщения об ошибках указывают на то, что компилятор хочет открыть скобу.

Скопировали ли вы код точно так же, как в своем приложении? На стороне Objective-C кажется, что некоторые вещи отсутствуют, а именно оператор присваивания "=", "nil", чтобы указать конец опций otherButtonTitles и ";" в конце вызова метода.

Для компилятора все, начиная с "UIAlertView *" до "[show alertview]"; выглядит как одно утверждение.

BTW Вы также можете использовать [NSString stringWithUTF8String:] вместо alloc/init'ing всех строк. Тот же эффект, меньше кода:

    UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:[NSString stringWithUTF8String:title]
                                                        message:[NSString stringWithUTF8String:message]
                                                       delegate:NULL
                                              cancelButtonTitle:[NSString stringWithUTF8String:ok]
                                              otherButtonTitles:[NSString stringWithUTF8String:cancel], nil];
