iOS：APNS推送主要代碼

標籤：

首先，在AppDelegate.m 中：

1，註冊通知

//[objc] view plaincopyprint?在CODE上查看代碼片派生到My Code片- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {      // Override point for customization after application launch.      ViewController *mainCtrl=[[ViewController alloc] init];      self.window.rootViewController=mainCtrl;            //註冊通知      if ([UIDevice currentDevice].systemVersion.doubleValue<8.0) {          [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge)];      }      else {          [[UIApplication sharedApplication] registerForRemoteNotifications];          [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil]];      }            //判斷是否由遠程訊息通知觸發應用程式啟動      if (launchOptions) {          //擷取應用程式訊息通知標記數（即小紅圈中的數字）          NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;          if (badge>0) {              //如果應用程式訊息通知標記數（即小紅圈中的數字）大於0，清除標記。              badge--;              //清除標記。清除小紅圈中數字，小紅圈中數字為0，小紅圈才會消除。              [UIApplication sharedApplication].applicationIconBadgeNumber = badge;              NSDictionary *pushInfo = [launchOptions objectForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"];                            //擷取推送詳情              NSString *pushString = [NSString stringWithFormat:@"%@",[pushInfo  objectForKey:@"aps"]];              UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"finish Loaunch" message:pushString delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil, nil nil];              [alert show];          }      }            return YES;  

2，註冊通知後，擷取device token

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {      NSString *token = [NSString stringWithFormat:@"%@", deviceToken];      NSLog(@"My token is:%@", token);      //這裡應將device token發送到伺服器端  }    - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {      NSString *error_str = [NSString stringWithFormat: @"%@", error];      NSLog(@"Failed to get token, error:%@", error_str);  }  

3，接收推播通知

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo  {      [UIApplication sharedApplication].applicationIconBadgeNumber=0;      for (id key in userInfo) {          NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);      }      /* eg.     key: aps, value: {         alert = "\U8fd9\U662f\U4e00\U6761\U6d4b\U8bd5\U4fe1\U606f";         badge = 1;         sound = default;     }      */      UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"remote notification" message:userInfo[@"aps"][@"alert"] delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil, nil nil];      [alert show];  }  

注意：app 前台運行時，會調用 remote notification；app後台運行時，點擊提醒框，會調用remote notification，點擊app 表徵圖，不調用remote notification，沒反應；app 沒有運行時，點擊提醒框，finishLaunching   中，launchOptions 傳參，點擊app 表徵圖，launchOptions 不傳參，不調用remote notification。
