iOS学习笔记之远程推送、静默推送与自定义消息推送

远程推送时 , 应用可能处于下列三种状态:

     (1) . 应用开启时 , 应用在前台

    (2) . 应用开启时 , 应用在后台

    (3) . 应用未启动(应用被杀死)

从苹果APNS服务器远程推送时:

1 . 如果应用处于 (1) 状态 , 则不会发出声音 , 会直接调用appDelegate的代理方法didReceiveRemoteNotification,此时如果想收到类似系统的弹窗提示,则需要自定义弹窗,提示音,振动(弹窗可以参考 : ForeNotification  (本地下载))

AudioServicesPlaySystemSound(1007);//系统提示音AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);//震动

2 . 如果应用处于 (2) 状态 , 则会发出提示音, 点击推送消息 , 则会调用appDelegate的代理方法didReceiveRemoteNotification

3 . 如果应用处于 (3) 状态,则会发出提示音 , 点击推送消息 , 则会开启应用 , 在下面这个方法中会带上launchOptions这个参数,如果实现了application:didReceiveRemoteNotification:fetchCompletionHandler:这个方法,则会调用这个方法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ NSDictionary *remoteNotification = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey]; if (remoteNotification) { //自定义的BOOL值,用来标记是从通知启动的应用 self.isLaunchedByNotification = YES; }else{ } [self checkIsLaunchedByNotification]; return YES;}

收到远程推送后 , 可以跳转到消息界面 :

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{ NSDictionary *aps = [userInfo valueForKey:@"aps"]; NSDictionary *alert = [aps valueForKey:@"alert"]; NSString * body = alert[@"body"]; if ([UIApplication sharedApplication].applicationState == UIApplicationStateActive) { //处于前台时  [EBForeNotification handleRemoteNotification:@{@"aps":@{@"alert":[NSString stringWithFormat:@"%@",body]}} soundID:1312];  }else{  //处于后台时  [self gotoMessageVC]; }}#pragma mark - 检测是否从通知栏启动得应用- (void)checkIsLaunchedByNotification{  if (self.isLaunchedByNotification) {  [self gotoMessageVC];  }}#pragma mark - 点击了通知菜单(当应用在前台时,收到推送,点击了自定义的弹窗,调用的方法)- (void)clickBannerView:(NSNotification *)notification{  NSDictionary * dict = notification.object;  [self gotoMessageVC];}#pragma mark - 跳转到消息界面(点击通知菜单／点击通知栏启动应用时)- (void)gotoMessageVC{  if([self.window.rootViewController isEqual:self.tabBarController]){  if([self.tabBarController.selectedViewController isKindOfClass:[UINavigationController class]]){  UINavigationController * nav = self.tabBarController.selectedViewController;    if (![nav.topViewController isKindOfClass:[MessagesViewController class]]) {    MessagesViewController *messageVC = [[MessagesViewController alloc] init];    messageVC.hidesBottomBarWhenPushed = YES;    [nav.visibleViewController.navigationController pushViewController:messageVC animated:YES];  } } }}
