Невозможно установить шрифт на SKLabelNode в tvOS

Question

У меня проблема, когда я пытаюсь создать экземпляр SKLabelNode с любым шрифтом под tvOS. Я использую следующие на основе документации (here):

SKLabelNode *label = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"]; 

Однако, шрифт не изменяется и используется шрифт по умолчанию. Я что-то упускаю?

Спасибо за помощь!

EDIT:

Очевидно, что некоторые шрифты IOS не доступны в данный момент на tvOS. В случае, если это помогает любому здесь список шрифтов, которые могут быть использованы в данный момент:

Answer 1

Используйте следующий фрагмент кода для проверки того Chalkduster является правильное название шрифта на tvOS:

NSArray *fontFamilies = [UIFont familyNames]; 
for (int i = 0; i < [fontFamilies count]; i++) 
{ 
    NSString *fontFamily = [fontFamilies objectAtIndex:i]; 
    NSArray *fontNames = [UIFont fontNamesForFamilyName:[fontFamilies objectAtIndex:i]]; 
    NSLog (@"%@: %@", fontFamily, fontNames); 
}
