и я получаю адрес веб-сайта, как это, но это всегда
NSString *urlString = [NSString stringWithFormat:@"%@", _gwtgDO.website];
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[[UIApplication sharedApplication] openURL:url];
Почему он всегда пуст, хотя я получаю ссылку на сайт с сервера правильно? это связано с тем, что я добавил атрибут позже? Что мне теперь делать?
всякий раз, когда вы изменяете файл xcdatamodel, вы регенерировать свои классы, чтобы заставить его работать. btw где основной код данных, где вы сохраняете.? – aahsanali
Я сохраняю в своем классе coreDataManager, я также заменил, удалил приложение из simuator..i отредактировал мой вопрос – NullData
