分析iOS推送通知

Question

我无法通过parse.com正确设置推送通知。我相信我的推送是因为它们通过解析显示在我的推送日志中。但是，无论我的推送发送到哪里（app或仪表盘），“发送的推送”总是显示0。我知道这可能是一个复杂的任务，所以任何帮助将是非常感谢！下面是我的代码：

AppDelegate.m

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

[application setStatusBarStyle:UIStatusBarStyleLightContent];
[self setupAppearance];

// Parse.com setup
[Parse setApplicationId:@"RgOpkkSfRoOFvealb8uUbdElx6e4VwqrNA0ObZLl"
              clientKey:@"GsMpLwqknU9c8qfPY0AaWUZzd7lE38ZTQQliM9TH"];
[PFUser enableRevocableSessionInBackground];

// Parse Push notifications setup
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                         categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];

return YES;
}

- (void)setupAppearance {
UINavigationBar *navigationBarAppearance = [UINavigationBar appearance];
navigationBarAppearance.barTintColor = [UIColor colorWithRed:0/255.0 green:0/255.0 blue:100/255.0 alpha:1.0f];
navigationBarAppearance.tintColor = [UIColor whiteColor];
navigationBarAppearance.titleTextAttributes = @{NSForegroundColorAttributeName:[UIColor whiteColor]};
}

// push notification
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.

PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
currentInstallation.channels = @[ @"global" ];
[currentInstallation saveInBackground];

// Associate the device with a user
PFInstallation *installation = [PFInstallation currentInstallation];
installation[@"user"] = [PFUser currentUser];
[installation saveInBackground];
}

// push notification
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
}

InboxTableViewController.m

ViewDidLoad

//push code
NSDictionary *data = @{
                       @"alert" : @"message!",
                       @"badge" : @"Increment"
                       };

PFPush *push = [[PFPush alloc] init];
[push setChannel:@"global"];
//[push setMessage:@"message!"];
[push setData:data];
[push sendPushInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
    if (!error) {
        NSLog(@"The push campaign has been created.");
    } else if (error.code == kPFErrorPushMisconfigured) {
        NSLog(@"Could not send push. Push is misconfigured: %@", error.description);
    } else {
        NSLog(@"Error sending push: %@", error.description);
    }
}];

我不相信您添加的“全球”频道是正确的。确保您订阅了“全局”频道（因为您在代码中正在推送到那个频道）。您可以在数据/安装下的解析控制台中执行此操作。您可以通过使用（从解析文档中）在代码中添加该通道：

[currentInstallation addUniqueObject:@"global" forKey:@"channels"];
[currentInstallation saveInBackground];

如果这不是您的问题，您可能没有正确设置证书。请仔细阅读文档，了解如何执行此操作。iOS证书已经够难的了，但当您添加另一个服务（如Parse）时，它就会使其变得更加困难。但最终还是值得的。
