IOS 用代码配置启动页

1，xcode版本10.1，首先在LaunchScreen.storyboard上设置一下StoryBoard ID 如图

2，在APPDelegate.m中增加属性：@property (strong, nonatomic) UIView *launchView

3，在- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions；中调用下面方法

-(void)setLaunchImg{

    UIViewController *viewController = [[UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil] instantiateViewControllerWithIdentifier:@"LaunchScreen"]

    self.launchView= viewController.view

    self.launchView.frame = CGRectMake(0, 0, self.window.screen.bounds.size.width, self.window.screen.bounds.size.height)

    [self.window addSubview:self.launchView]

    UIImageView*imageV = [[UIImageViewalloc]initWithFrame:CGRectMake(0,0,self.launchView.frame.size.width,self.launchView.frame.size.height)]

    [imageVsetImage:[UIImageimageNamed:@"logo.jpeg"]]

    imageV.contentMode = UIViewContentModeScaleAspectFill

    [self.launchViewaddSubview:imageV]

    [self.window bringSubviewToFront:self.launchView]

//可以设置启动页的存在时间

    [NSTimer scheduledTimerWithTimeInterval:3 target:self selector:@selector(removeLun) userInfo:nil repeats:NO]

}

-(void)removeLun

{

    [self.launchView removeFromSuperview]

}

iOS APP启动画面必须是静态图片。但是你可以在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

里面载入你写着动画的view。在动画结束以后再进入程序。

只能通过这样的伪启动动画来做
