//UIWindow数组中最后调用makeKeyAndVisible方法的UIWindow对象
[application keyWindow];
[application beginIgnoringInteractionEvents];//开始忽略Event
//...中间调用动画等操作
[application endIgnoringInteractionEvents];//结束忽略Event
application.applicationSupportsShakeToEdit = YES; //晃动是否有撤销或者重做动作
NSURL *URL=nil;
//不设置options,启动Safari方式打开这个Link的代表的网站
[application openURL:URL options:@{} completionHandler:nil];
//设置options @{UIApplicationOpenURLOptionUniversalLinksOnly : @YES}
//打开Universal Link所对应的App

//不让手机休眠

//隐藏状态条
[application setStatusBarHidden:YES];

//设置状态条的方向
[application setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];
//状态条的Frame
[application statusBarFrame];
//网络是否可见--小菊花

UIApplicationDelegate方法
// 程序启动将要完成的时候调用
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(nullable NSDictionary *)launchOptions{
//被其他应用调用--UIApplicationLaunchOptionsURLKey
NSURL *url = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];
if(url) {//做出相应的判断
if ([[url scheme] isEqualToString:@"myapp"]) {
//处理链接
}
}
//若用户直接启动，lauchOptions内无数据;
//若由其他应用程序通过openURL:启动，则UIApplicationLaunchOptionsURLKey对应的对象为启动URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString)；
//若由本地通知启动，则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification)；
//若由远程通知启动，则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo（NSDictionary）；
return YES;
}
// 程序启动完成的时候调用
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(nullable NSDictionary *)launchOptions{return YES;}
// 当应用程序获取焦点的时候调用--恢复数据
- (void)applicationDidBecomeActive:(UIApplication *)application{}
// 当应用程序失去焦点的时候调用--保存数据
- (void)applicationWillResignActive:(UIApplication *)application{}
// 当应用程序进入后台的时候调用，
- (void)applicationDidEnterBackground:(UIApplication *)application{}
// 当应用程序进入进台的时候调用
- (void)applicationWillEnterForeground:(UIApplication *)application{}
// 程序内存警告，可以一些内存的释放来抢救程序，如SD的缓存清除
- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application{}
// 当应用程序关闭的时候调用
- (void)applicationWillTerminate:(UIApplication *)application{}
/**
以上是UIApplication基本的周期方法，会有很多种情况：
1、程序启动：
willFinishLaunchingWithOptions -> didFinishLaunchingWithOptions -> applicationDidBecomeActive
2、程序从前台退出到后台
applicationWillResignActive -> applicationDidEnterBackground
3、程序从后台进入到前台
applicationWillEnterForeground -> applicationDidBecomeActive
4、双击home键切换程序：
applicationWillResignActive -> applicationDidEnterBackground
5、在前台双击home键杀死程序
applicationWillResignActive -> applicationDidEnterBackground -> applicationWillTerminate
6、从其他程序前台双击home键杀死后台程序
applicationWillTerminate
7、下拉通知栏或者上拉工具栏
applicationWillResignActive

推送这块苹果一直改，IOS7改到IOS10了，苹果爹爹厉害，年年在修改推送，项目已经一堆判断，理解并总结iOS7-10推送通知流程
最后还是用第三方（极光、个推），感谢他们😁
