如何使故事与Instagram相同

Question

我想要实现一个类似Instagram和WhatsApp应用程序的故事（图像和视频）。诸如使用自定义字体和颜色在图像和视频上添加文本等功能。请参见下图作为参考

有什么主意吗？我为Add text on the image推荐了以下内容，但没有太多帮助。

Answer 1

尝试一下：

let imagePlaceholder = "[ImagePlaceholder]"
let fullString = String(format: "Hello %@", imagePlaceholder)
let attributes: [NSAttributedStringKey: Any] = [.font: UIFont.systemFont(ofSize: 16), .foregroundColor: UIColor.white]
let attributedString = NSMutableAttributedString(string: fullString, attributes: attributes)

if let imagePlaceholderRange = fullString.range(of: imagePlaceholder) {
    let range = NSRange(imagePlaceholderRange, in: fullString)
    let attachment = NSTextAttachment()
    let myImage = UIImage(named: "MyImage")
    attachment.image = myImage

    let stringAttachment = NSAttributedString(attachment: attachment)
    attributedString.replaceCharacters(in: range, with: stringAttachment)
}
myLabel.attributedText = attributedString

Answer 2

您需要添加CSS或任何phostoshop

如果是css，则表示您需要wotk不透明度：0.5 在图片上添加div 添加文字
