プログラムでUIButtonタイトルUILabelフォントサイズを設定する


回答:


617
button.titleLabel.font = [UIFont systemFontOfSize:size];

助けるべき


詳細を教えてください。問題はフォントの設定ではなく、他の場所にあると思います。別の質問として投稿する価値がありますか?
ウラジミール

それは別の場所にありました。この線の上にテキストの色を設定したところ、デフォルトのフォントの色が白であることがわかりました。そのため、白い背景に白いテキストが表示されていました。フォントを設定した後、textColorを設定する必要があり、意図したとおりに機能しました。

これは悪いですか?フォントをラベルに割り当てるたびにUIFontオブジェクトを作成します。100個のラベルがあるとすると、100個のUIFontインスタンスが作成されますか?

UIFontリファレンスは、「これらのメソッドは、指定された特性を持つ既存のフォントオブジェクトをチェックし、存在する場合はそれを返す」と述べているため、同じフォントが100回読み込まれることはありません。

なぜSwiftの編集を拒否したのか分からないので、これが回答に価値を与えると思います。

[button setFont:...] 廃止されました。

[button.titleLabel setFont:...]代わりに使用してください。例:

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

umm ... usingはと[button.titleLabel setFont:myFont]完全に等しくbutton.titleLabel.font = myFont、同じプロパティセッターを使用するためのまったく異なる表記

glenstoreyは、ボタンで直接使用するためのsetFontが非推奨であることを意味していたので、[myButton setFont]は非推奨です。
kris

非推奨とはどういう意味ですか?つまり、機能しなくなりますか?

このようなものを使用して、フォントサイズとフォントスタイルを設定することもできます。それはあなたが求めているものより少しだけですが、ちょっと、何が一体...

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

そして、もしあなたが厄介だと感じているなら、このコードを実装してxCodeデバッガーで出力をチェックすることで、利用可能なフォントのリストを見つけることができます。

コード:

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]);
    }
}

利用可能なフォントを確認する簡単な方法:iosfonts.com
titusmagnus

Objective-C:

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

迅速:

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

フォントサイズを変更するだけです。


あなたのコードは、仕事ではなく、shareButton.titleLabel .font = UIFont.systemFontOfSize(サイズ)の作品?

以下を使用できます。

button.titleLabel.font = [UIFont systemFontOfSize:14.0];

興味深い、ストーリーボードでの最大数は300ですが、コードでは無制限

これは役に立ちます

button.titleLabel.font = [UIFont fontWithName:@"YOUR FONTNAME" size:12.0f]

13

お役に立てれば幸いです

[_button.titleLabel setFont:[UIFont systemFontOfSize:15]];  

幸運を

迅速:

shareButton.titleLabel?.font = UIFont.systemFontOfSize(size)

スウィフト4

button.titleLabel?.font = UIFont(name: "Font_Name_Here", size: Font_Size_Here)

Objective-c

[button.titleLabel setFont:[UIFont fontWithName:@“Font_Name_Here size: Font_Size_Here]];

例:

Font_Name = "Helvetica"

Font_Size = 16.0

それが役に立てば幸い。


7
button.titleLabel.font = <whatever font you want>

あなたがそうした場合、彼らのテキストがなぜ表示されないのか疑問に思う人々のために

button.titleLabel.text = @"something";

それは表示されません、あなたがする必要があります:

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

6

ボタンのフォントを太字、斜体でカスタマイズすることもできます。この例では、太字のシステムフォントサイズを使用しています。

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

このようにして、fontSizeを設定し、1つで処理できます。 classます。

1.作成したextensionのがUIButton次のコードを追加しました:

- (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 UIButton内部コードを作成する

今、あなたが作成した場合UIButton、あなたのコード内のUIButton`をし、ボタンを作成します。#importextension of your

2.2でボタンを作成 Interface Builder

UIButton内に作成した場合はInterface Builder、を選択しUIButton、に移動して、Identity Inspectorextension同様classに作成したものを追加しUIButtonます。

「ターゲットメンバーシップ」のチェックボックスが追加されているかどうか、カスタムフォント名を確認します。これは役立つはずです。

UIButtonのユーザー補助機能をサポートするには

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)
    }
}

あなたは今フォントをボタンすることができます。

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