Нагрузка ошибок CGContext без видимых причин

Question

Я работаю над этим проектом на прошлой неделе, и все отлично работает в симуляторе. Как раз этим вечером, когда я пошел, чтобы запустить его, я получил весь этот плот новых ошибок, и единственный код, который я добавил с момента последней плавной сборки/моделирования, был следующим, чтобы добавить словарь из файла, который я только что создал.

Я определенно находится в крутой части кривой обучения Objective-C и Xcode, и эти ошибки не звонят вообще, потому что я не использовал какой-либо код, который они ссылаются в моем проекте, если они каким-то образом не связаны с кодом, который создается за кулисами во время разработки пользовательского интерфейса в раскадровке. Заранее спасибо за помощь!

Вот код, который я использовал, чтобы добавить свой словарь:

- (void)calculate 
    { 
     // Retrieve the dictionary containing the chart 
     NSString *path = [[NSBundle mainBundle] pathForResource:@"chart" ofType:@"plist"]; 
     NSDictionary *chart = [NSDictionary dictionaryWithContentsOfFile: path]; 


    } 

А вот журнал ошибок:

Это известная ошибка в iOS7 ... просто пусть это быть таким ... Если я прав, это не будет появляться каждый раз. В настоящее время нет обходного пути. попробуйте обновиться до 7.0.3. для получения дополнительной информации this question. Вы можете найти множество таких вопросов на StackOverflow. Не волнуйтесь .. продолжайте работать. Сообщите мне, если вы все еще недовольны моим ответом. .. :) Я знаю, что его нелегко переварить, но вам нужно ... :(
