在我基于Game Center的回合制游戏中，我当前遇到有关应用程序图标徽章计数的问题。当我拒绝参加游戏的邀请时，徽章计数仍显示1条通知。
我什至尝试使用extension String {
/// Generates a `UIImage` instance from this string using a specified
/// attributes and size.
///
/// - Parameters:
/// - attributes: to draw this string with. Default is `nil`.
/// - size: of the image to return.
/// - Returns: a `UIImage` instance from this string using a specified
/// attributes and size, or `nil` if the operation fails.
func image(withAttributes attributes: [NSAttributedString.Key: Any]? = nil, size: CGSize? = nil) -> UIImage? {
let size = size ?? (self as NSString).size(withAttributes: attributes)
UIGraphicsBeginImageContext(size)
(self as NSString).draw(in: CGRect(origin: .zero, size: size),
withAttributes: attributes)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
}
来工作，直到重新启动游戏并加载游戏比赛为止。
即使没有匹配项，图标也会显示为1。仅在开始新比赛时才将其删除。
