Question

我试图找出如何检查推送通知的有效负载，以便确定当用户从通知中打开应用时打开哪个视图。例如，如果通知说＆＃34; x：test＆＃34;当点击通知并且通知显示＆＃34; y：test＆＃34;视图你会打开。

编辑：我想我应该澄清一下我不确定的部分。

我在didFinishLaunchingWithOptions中有这个：

UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

    if (notification)
    {
        // check payload then load appropriate view controller
    }

如何检查某些文本的有效负载以确定要加载的相应视图控制器？

Answer 1

在app delegate

中的两个地方处理接收推送通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions。在这种情况下，您的推送通知数据包含在[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo。在这种情况下，userInfo是您的推送通知数据。

这是我过去项目的代码。通知显示在这样的设备中＆＃34; Kostas：想要将您添加为朋友＆＃34;。

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

NSDictionary *remoteNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

if (remoteNotif) {

    NSString *name = [[NSString alloc] init];
    NSString *message = [[NSString alloc] init];
    // 'wants to add you as friend.'
    NSString* alertValue = [[remoteNotif valueForKey:@"aps"] valueForKey:@"alert"];

    NSMutableArray* parts = [NSMutableArray arrayWithArray:[alertValue componentsSeparatedByString:@": "]];
    name = [parts objectAtIndex:0];
    [parts removeObjectAtIndex:0];
    message = [parts componentsJoinedByString:@": "];

    if ([message isEqualToString:@": wants to add you as friend."]) {
        UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;
        // tabController.delegate = self;
        tabController.selectedIndex = 1;
    }
    else{
        UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;
        // tabController.delegate = self;
        tabController.selectedIndex = 2;

        [self addMessageFromRemoteNotification:remoteNotif updateUI:NO];
    }
