Comment puis-je ajouter un attribut d'alignement de texte à un NSAttributedString pour centrer le texte?
Edit: Est-ce que je fais quelque chose de mal? Cela ne semble pas changer l'alignement.
CTParagraphStyleSetting setting;
setting.spec = kCTParagraphStyleSpecifierAlignment;
setting.valueSize = kCTCenterTextAlignment;
CTParagraphStyleSetting settings[1] = {
{kCTParagraphStyleSpecifierAlignment, sizeof(CGFloat), &setting},
};
CTParagraphStyleRef paragraph = CTParagraphStyleCreate(settings, sizeof(setting));
NSMutableAttributedString *mutableAttributed = [[NSMutableAttributedString alloc] initWithAttributedString:self.attributedString];
[mutableAttributed addAttributes:[NSDictionary dictionaryWithObjectsAndKeys:(NSObject*)paragraph ,(NSString*) kCTParagraphStyleAttributeName, nil] range:_selectedRange];
