各個(gè)程序運(yùn)行狀態(tài)時(shí)代理的回調(diào)
告訴代理進(jìn)程啟動(dòng)但還沒(méi)進(jìn)入狀態(tài)保存
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions
告訴代理啟動(dòng)基本完成程序準(zhǔn)備開(kāi)始運(yùn)行
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
當(dāng)應(yīng)用程序?qū)⒁敕腔顒?dòng)狀態(tài)執(zhí)行，在此期間檩互，應(yīng)用程序不接收消息或事件富寿，比如來(lái)電話了
- (void)applicationWillResignActive:(UIApplication *)application
當(dāng)應(yīng)用程序入活動(dòng)狀態(tài)執(zhí)行，這個(gè)剛好跟上面那個(gè)方法相反
- (void)applicationDidBecomeActive:(UIApplication *)application
當(dāng)程序被推送到后臺(tái)的時(shí)候調(diào)用。所以要設(shè)置后臺(tái)繼續(xù)運(yùn)行，則在這個(gè)函數(shù)里面設(shè)置即可
- (void)applicationDidEnterBackground:(UIApplication *)application
當(dāng)程序從后臺(tái)將要重新回到前臺(tái)時(shí)候調(diào)用，這個(gè)剛好跟上面的那個(gè)方法相反纱兑。
- (void)applicationWillEnterForeground:(UIApplication *)application
當(dāng)程序?qū)⒁顺鍪潜徽{(diào)用，通常是用來(lái)保存數(shù)據(jù)和一些退出前的清理工作化借。這個(gè)需要要設(shè)置UIApplicationExitsOnSuspend的鍵值潜慎。
- (void)applicationWillTerminate:(UIApplication *)application
當(dāng)程序載入后執(zhí)行
- (void)applicationDidFinishLaunching:(UIApplication*)application
