我想为我的图像创建一个文本覆盖。问题是,如果我尝试添加第二个文本,比如字幕,它会忽略我的字体大小。
titleLayer.frame = CGRectMake(0, 80, imageView.bounds.width, 50)
subTitleLayer.frame = CGRectMake(0, 130, imageView.bounds.width, 40)
titleLayer.string = "Title"
subTitleLayer.string = "Subtitle"
let fontName: CFStringRef = "HelveticaNeue"
let fontSubName: CFStringRef = "HelveticaNeue-Thin"
titleLayer.font = CTFontCreateWithName(fontName, 16, nil)
subTitleLayer.font = CTFontCreateWithName(fontSubName, 10, nil) // Ignores the font-size
imageView.layer.addSublayer(titleLayer)
imageView.layer.addSublayer(subTitleLayer)
新字体是正确的,但它总是和 titleFont 一样大小(16)。如何更改字体大小?
