今天新项目中加入SVProgressHUD的时候发现菊花出现在了左上角,不管怎么弄都无法改变。最后尝试删除了iOS11中新加入的SceneDelegate发现问题解决了,至于是什么原理,和后续可能会出现什么问题,恕我回答不了QAQ。
具体删除方式如下:
1、删除Scenedelegate的.h.m文件
2、删除Info.plist文件中的Application Scene Manifest配置
3、注释或者删除AppDelegate.m文件中的两个管理Scenedelegate生命周期代理方法
#pragma mark - UISceneSession lifecycle
- (UISceneConfiguration *)application:(UIApplication *)application configurationForConnectingSceneSession:(UISceneSession *)connectingSceneSession options:(UISceneConnectionOptions *)options {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return [[UISceneConfiguration alloc] initWithName:@"Default Configuration" sessionRole:connectingSceneSession.role];
}
- (void)application:(UIApplication *)application didDiscardSceneSessions:(NSSet<UISceneSession *> *)sceneSessions {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
4、在AppDelegate.h中,添加window属性
@property (strong, nonatomic) UIWindow *window;
