iOS 10.3+ 动态修改 App 图标
支持系统:
- iOS 10.3+
- tvOS 10.2+
官方 API:
@interface UIApplication (UIAlternateApplicationIcons) // If false, alternate icons are not supported for the current process. @property (readonly, nonatomic) BOOL supportsAlternateIcons NS_EXTENSION_UNAVAILABLE("Extensions may not have alternate icons") API_AVAILABLE(ios(10.3), tvos(10.2)); // Pass `nil` to use the primary application icon. The completion handler will be invoked asynchronously on an arbitrary background queue; be sure to dispatch back to the main queue before doing any further UI work. - (void)setAlternateIconName:(nullable NSString *)alternateIconName completionHandler:(nullable void (^)(NSError *_Nullable error))completionHandler NS_EXTENSION_UNAVAILABLE("Extensions may not have alternate icons") API_AVAILABLE(ios(10.3), tvos(10.2)); // If `nil`, the primary application icon is being used. @property (nullable, readonly, nonatomic) NSString *alternateIconName NS_EXTENSION_UNAVAILABLE("Extensions may not have alternate icons") API_AVAILABLE(ios(10.3), tvos(10.2)); @end
步骤:
在 info.plist 文件中新增 Icon files (iOS 5)
其中,Primary Icon 是应用默认图标
Xcode 中,默认 没有 CFBundleAlternateIcons,需要删掉 Newstand Icon,添加上 CFBundleAlternateIcons。
Primary Icon 可不用设置,使用系统默认的 Assets.xcassets 中的 AppIcon。
