ZeroPush-iOS: An Objective-C repository from archfear

Purpose:

ZeroPush-iOS is a lightweight Obj-C wrapper around the ZeroPush API. It provides some convenience methods to help you get up an running with ZeroPush as quickly as possible.

Building/Linking/Adding to your project:

We recommend using the ZeroPush Cocoapod.

In your Podfile add the following line:

pod 'ZeroPush', '~> 2.0'

and install the Pods

$> pod install

Configuration:

After the client library has been installed, add the following to your AppDelegate.

//In AppDelegate.h - Add the ZeroPushDelegate

#import "ZeroPush.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate, ZeroPushDelegate>


// In AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

#if DEBUG
    [ZeroPush engageWithAPIKey:@"iosdev_apptoken" delegate:self];
#else
    [ZeroPush engageWithAPIKey:@"iosprod_apptoken" delegate:self];
#endif

    //now ask the user if they want to recieve push notifications. You can place this in another part of your app.
    [[ZeroPush shared] registerForRemoteNotifications];
    
    return true;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)tokenData
{
    // Call the convenience method registerDeviceToken, this helps us track device tokens for you
    [[ZeroPush shared] registerDeviceToken:tokenData];

    // This would be a good time to save the token and associate it with a user that you want to notify later.
    NSString *tokenString = [ZeroPush deviceTokenFromData:tokenData];
    NSLog(@"%@", tokenString);

    // For instance you can associate it with a user's email address
    // [[ZeroPush shared] subscribeToChannel:@"user@example.com"];
    // You can then use the /broadcast endpoint to notify all devices subscribed to that email address. No need to save tokens!
    // Don't forget to unsubscribe from the channel when the user logs out of your app!
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"%@", [error description]);
    //Common reason for errors:
    //  1.) Simulator does not support receiving push notifications
    //  2.) User rejected push alert
    //  3.) "no valid 'aps-environment' entitlement string found for application"
    //      This means your provisioning profile does not have Push Notifications configured. https://zeropush.com/documentation/generating_certificates
}

Upgrading from iOS7

If you were using the helper method [[ZeroPush shared] registerForRemoteNotificationTypes:] in iOS7, you will need to change it when deploying to iOS8

Before:

[[ZeroPush shared] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

After:

[[ZeroPush shared] registerForRemoteNotifications];
