SceneDelegate
在Xcode11.0以后创建项目，运行项目出现bug时遇到的问题之一，我的解决方法。
报错：
-[AppDelegate setWindow:]: unrecognized selector sent to instance 0x60000002b440
修改方法：
在AppDelegate.h里加声明window
@property (nonatomic, strong) UIWindow * window;
运行问题解决
兼容13和13以前的项目AppDelegate和SceneDelegate类方法里设置
在AppDelegate.m设置
-
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
if (@available(iOS 13.0, *)) {} else {
self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds]; self.window.rootViewController = [[UITabBarController alloc]init]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible];}
return YES;
}
在SceneDelegate.m里设置UIWindowScene *windowScene = (UIWindowScene *)scene;
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window = [[UIWindow alloc] initWithWindowScene:windowScene];
[self.window setWindowScene:windowScene];
[self.window setBackgroundColor:[UIColor whiteColor]];
[self.window setRootViewController:[UITabBarController new]];[self.window makeKeyAndVisible];
运行就OK了
