一、准备工作
1、添加一个LaunchImage，添加常用手机尺寸启动图片，并配置Target如图：
配置
二、撸代码
1、添加一个AppDelegate的分类
2、在AppDelegate中导入这个分类
#import "AppDelegate.h"
#import "ViewController.h"
#import "AppDelegate+LanuchAD.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
ViewController *vc = [[ViewController alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
//广告
[self setupLaunchImage];
return YES;
}
3、 广告[self setupLaunchImage]
