Você pode fornecer mais detalhes? Eu acho que o problema está em algum outro lugar, não na configuração da fonte. Vale a pena ser publicado como uma pergunta separada?

Foi em algum outro lugar. Eu havia definido minha cor do texto acima dessa linha e percebi que a cor da fonte padrão é branca. Por isso, exibia texto em branco sobre fundo branco. Tinha que definir o textColor depois que eu defini a fonte e funcionou como pretendido.

Isso é ruim? Ele cria um objeto UIFont toda vez que você atribui uma fonte a um rótulo. Suponha que eu tenha 100 rótulos. Ele criará 100 instâncias do UIFont?

Reenvio UIFont que "Estes métodos de verificação de um objeto de fonte existente com as características especificadas e devolvê-lo se ele existir", então você não deve acabar com a mesma fonte carregado 100 vezes

Não sei por que você recusou a edição Swift, acho que isso agregaria valor à resposta.

[button setFont:...] foi descontinuado.

Use em [button.titleLabel setFont:...]vez disso, por exemplo:

[myButton.titleLabel setFont:[UIFont systemFontOfSize:10]];

umm ... usando [button.titleLabel setFont:myFont]é exatamente e absolutamente igual button.titleLabel.font = myFont, a sua notação apenas diferente para usar a mesma propriedade setter

Acho que glenstorey significa que o setFont está obsoleto para uso com o botão diretamente, então [myButton setFont] está obsoleto.

O que significa ser reprovado? Isso significa que não funcionará mais?

Você também pode definir o tamanho da fonte e o estilo da fonte usando algo como isto. É um pouco mais do que você está pedindo, mas ei, que diabos ...

[myButton.titleLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13.0]];

E ... se você estiver se sentindo brincalhão, uma lista de fontes disponíveis pode ser encontrada implementando este código e depois verificando a saída no seu depurador xCode.

Código:

NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
NSArray *fontNames;
NSInteger indFamily, indFont;
for (indFamily=0; indFamily<[familyNames count]; ++indFamily)
{
    NSLog(@"Family name: %@", [familyNames objectAtIndex:indFamily]);
    fontNames = [[NSArray alloc] initWithArray:
            [UIFont fontNamesForFamilyName:
            [familyNames objectAtIndex:indFamily]]];
    for (indFont=0; indFont<[fontNames count]; ++indFont)
    {
        NSLog(@"    Font name: %@", [fontNames objectAtIndex:indFont]);
    }
}

Objetivo-C:

[button.titleLabel setFont: [button.titleLabel.font fontWithSize: sizeYouWant]];

Rápido:

button.titleLabel?.font = button.titleLabel?.font.fontWithSize(sizeYouWant)

não fará nada além de alterar o tamanho da fonte.

button.titleLabel.font = <whatever font you want>

Para as pessoas que se perguntam por que o texto não está aparecendo, se você

button.titleLabel.text = @"something";

Não aparecerá, você precisa fazer:

[button setTitle:@"My title" forState:UIControlStateNormal]; //or whatever you want the control state to be

você também pode personalizar a fonte do botão com negrito, itálico. neste exemplo com tamanho de fonte do sistema em negrito.

[LoginButton.titleLabel setFont:[UIFont boldSystemFontOfSize:15.0f*Ratio]];

Isso deve fazer você ir

[btn_submit.titleLabel setFont:[UIFont systemFontOfSize:14.0f]];
— Dalee Davis

Dessa forma, você pode definir o fontSize e lidar com isso em apenas um class .

1. Criou um extensiondos UIButtone adicionou o seguinte código:

- (void)awakeFromNib{

    [super awakeFromNib];

    [self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [self.titleLabel setFont:[UIFont fontWithName:@"font" 
                                     size:self.titleLabel.font.pointSize]];
    [self setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];
}

2.1 Criar UIButtoncódigo interno

Agora, se você criar um UIButtondentro do seu código, #importo extension of yourUIButton` e crie o Button.

2.2 Botão Criar Interface Builder

Se você criar o UIButtoninterior do Interface Builder, selecione o UIButton, vá para o Identity Inspectore adicione o criado extensioncomo classpara o UIButton.

Para dar suporte ao recurso de acessibilidade no UIButton 

extension UILabel
{
   func scaledFont(for font: UIFont) -> UIFont {
        if #available(iOS 11.0, *) {
            return UIFontMetrics.default.scaledFont(for: font)
        } else {
            return font.withSize(scaler * font.pointSize)
        }
    }
    func customFontScaleFactor(font : UIFont) {
        translatesAutoresizingMaskIntoConstraints = false

         self.adjustsFontForContentSizeCategory = true
         self.font = FontMetrics.scaledFont(for: font)
    }
}

Você pode abotoar a fonte agora.

UIButton().titleLabel?.customFontScaleFactor(font: UIFont.systemFont(ofSize: 12))
