緊接3.8特殊節(jié)日的文章Xcode 11新建項(xiàng)目,繼續(xù)學(xué)習(xí)
自xcode11新增SceneDelegate后土辩，SceneDelegate與Man.storyboard該如何處理：
1. 第一種情況支救，刪除SceneDelegate，但保留Man.storyboard：
- 刪除info.plist中的
Application Scene Manifest一項(xiàng) - 在AppDelegate.h中添加window屬性
@property (strong, nonatomic) UIWindow *window; - 刪除AppDelegate.m中新增的兩個(gè)UIScene方法
- 刪除UISceneDelegate類(lèi)文件
切記要在AppDelegate.h中添加window屬性拷淘，否則Man.storyboard無(wú)法正常加載
2. 第二種情況各墨，刪除SceneDelegate且刪除Man.storyboard：
- 刪除info.plist中的
Application Scene Manifest一項(xiàng) - 在AppDelegate.h中添加window屬性
@property (strong, nonatomic) UIWindow *window;} - 刪除AppDelegate.m中新增的兩個(gè)UIScene方法
- 刪除UISceneDelegate類(lèi)文件
- 刪除Main.storeboaard文件
- 項(xiàng)目
TARGETS->General->Main Interface置為空 - 刪除info.plist中
Main storyboard file base name一項(xiàng) - AppDelegate.m中導(dǎo)入目標(biāo)頭文件，在
didFinishLaunchingWithOptions方法中添加目標(biāo)類(lèi)：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] init];
self.window.frame = [UIScreen mainScreen].bounds;
self.window.backgroundColor = [UIColor whiteColor];
ViewController * vc = [[ViewController alloc]init];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
return YES;
}
3. 第三種情況启涯，保留SceneDelegate但刪除Man.storyboard：
- 項(xiàng)目
TARGETS->General->Main Interface置為空 - 刪除info.plist中
Main storyboard file base name一項(xiàng) - 刪除info.plist中
Application Scene Manifest -> Scene Configuration -> Application Scene Role -> Item 0 -> Storyboard name一項(xiàng) - SceneDelegate.m中導(dǎo)入目標(biāo)頭文件贬堵，在
willConnectToSession方法中添加目標(biāo)類(lèi)：
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
if ([scene isKindOfClass:[UIWindowScene class]]) {
UIWindowScene *windowScene = (UIWindowScene*)scene;
self.window = [[UIWindow alloc] initWithWindowScene:windowScene];
self.window.frame = [UIScreen mainScreen].bounds;
self.window.backgroundColor = [UIColor whiteColor];
ViewController * vc = [[ViewController alloc]init];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
}
}
