一、删除默认主页Main.storyboard
1、删除Main.storyboard文件
2、选中项目----General ---- Deployment Info —— 清空Main Interface的Main,此时会自动删除Info.plist中的
<key>UIMainStoryboardFile</key> <string>Main</string>
如果没删除,检查后删除。
3、也可以删除或不删除自动生成的ViewController文件,这里选择删除,选中,右键 Delete , Move to Trash
此时在真机运行会先显示白色(因为有启动页),后显示黑色(无主页)
4、指定General ---- Deployment Info 的iOS 13.0
IPHONEOS_DEPLOYMENT_TARGET = 13.0;
5、APP只适配iPhone,不适配iPad
原来的 TARGETED_DEVICE_FAMILY = "1,2";
会变为 TARGETED_DEVICE_FAMILY = 1;

二、自定义首页及跳转
1、New file —— Cocoa Touch Class,创建两个UIViewController,一个选中Also create XIB file,另一个不选中
FirstViewController不选Also create XIB file
SecondViewController选中Also create XIB file
2、在AppDelegate.h中添加属性window
@interface AppDelegate : UIResponder <UIApplicationDelegate> @property (strong, nonatomic) UIWindow *window; @end
3、在AppDelegate.m的didFinishLaunchingWithOptions中设置window的基本信息,并设置根UIViewController,设置完成后运行即跳转到对应页面
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; //给出默认背景颜色,如果此处不给背景颜色,其他页面巧合也没给背景颜色,则进入到页面中时显示黑色 self.window.backgroundColor = [UIColor whiteColor]; //不带xib的UIViewController //FirstViewController *vc = [[FirstViewController alloc] init]; //带xib的UIViewController SecondViewController *vcs = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:vcs]; self.window.rootViewController = navi; [self.window makeKeyAndVisible]; return YES; }
