UILabel 阴影已被不需要的切断

[英]UILabel Shadow Has Unwanted Cut Off

我有一个添加阴影的 UILabel。 UILabel 显示出来,阴影也显示出来,但最左边的阴影被切掉,使其与文本的边缘保持一致。 我移动了标签的位置以查看它是否被视图覆盖,但一切都保持不变。 我还取出了 sizeToFit,它保持不变。 下面是标签的初始化:

    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);

我有这个问题有一个自定义的字体和通过继承的UILabel并添加解决它shadowOffsetintrinsicContentSize与此覆盖:

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

我想你需要补充一下

scoreLabel.clipsToBounds = NO;

这是您想要的解决方案:

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

我添加了这个,切断消失了:

scoreLabel.textAlignment = NSTextAlignmentCenter;
