UILabel 陰影已被不需要的切斷

Question

我有一個添加陰影的 UILabel。 UILabel 顯示出來，陰影也顯示出來，但最左邊的陰影被切掉，使其與文本的邊緣保持一致。 我移動了標簽的位置以查看它是否被視圖覆蓋，但一切都保持不變。 我還取出了 sizeToFit，它保持不變。 下面是標簽的初始化：

    UILabel *scoreLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] bounds].size.height)];
    scoreLabel.text = text;
    [scoreLabel setFont:[UIFont fontWithName:fontName size:fontSize]];
    scoreLabel.textColor = [UIColor colorWithRed:red green:green blue:blue alpha:1.0];

    scoreLabel.shadowColor = [UIColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:1.0f];
    scoreLabel.shadowOffset = CGSizeMake(-10.0, 2.0);
    scoreLabel.clipsToBounds = NO;

    [scoreLabel sizeToFit];

    scoreLabel.center = CGPointMake(x, y);

Answer 1

我有這個問題有一個自定義的字體和通過繼承的UILabel並添加解決它shadowOffset到intrinsicContentSize與此覆蓋：

override var intrinsicContentSize: CGSize  {
    get {
        let s = super.intrinsicContentSize
        return CGSize(width: s.width + abs(shadowOffset.width), height: s.height + abs(shadowOffset.height))
    }
}

Answer 2

我想你需要補充一下

scoreLabel.clipsToBounds = NO;

Answer 3

這是您想要的解決方案：

let style = NSMutableParagraphStyle()
style.firstLineHeadIndent = someInset // can be shadowBlur and/or shadowRadius
style.headIndent = someInset
style.tailIndent = -someInset // must be negative since its at the end (tail)

let attrString = NSMutableAttributedString(string: "Some Text")
attrString.addAttribute(.paragraphStyle, value: style, range: .init(location: 0, attrString.length)
let label = UILabel()
label.numberOfLines = 0 // not necessary
label.attributedText = attrString

Answer 4

我添加了這個，切斷消失了：

scoreLabel.textAlignment = NSTextAlignmentCenter;
