使用 Assets.xcassets
外面的根目录下 image 才可以正常渲染 Launch Screen 的背景图片,Why???

iOS 15 bug
version bug
- iOS 14 ✅
- iOS 15 ❌
??? iOS 14 ✅,然后切换到 iOS 15 突然好了✅
solutions ???
1.查看图片尺寸是否正确,是否添加约束
2.检查TARGETS → General → App Icons and Launch Images 下 Launch Screen File 设置是否是 LaunchScreen 这个同名的 storyboard 文件
3.图片资源不能放置在 Assets.xcasset 文件夹中, 要直接拖拽到与 Assets.xcasset 文件夹同层的项目根目录下 ✅, 可以但是不推荐,无法自适应 Dark 模式 👎
4.卸载 app,重新构建 Command+R
- 可以通过清理以下文件夹编译缓存文件 ✅
~/Library/Developer/Xcode/DerivedData
- 清理缓存
import UIKit
public extension UIApplication {
func clearLaunchScreenCache() {
do {
try FileManager.default.removeItem(atPath: NSHomeDirectory()+"/Library/SplashBoard")
} catch {
print("Failed to delete launch screen cache: \\(error)")
}
}
// UIApplication.shared.clearLaunchScreenCache();
Library 文件夹中有一个名为 SplashBoard
的文件夹,该文件夹是启动屏缓存
的存储位置
