iOS極光推送集成

文章已移到新的博客：http://www.henishuo.com/ios-jpush/

！

稍稍研究了一下極光推送，其實是非常簡單的，不過這個過程也出現了一些問題。

對於應用在前臺時，需要額外處理一下。

關於極光推送，由於在iOS8之後，有了新的API，因此極光也給我們提供了適配的API。

下面我就把對極光推送相關API的封裝提取出來，希望對大家有幫助，同時也當是總結。

下面是對極光推送而封裝的一個工具類：

@interface HYBJPushHelper : NSObject

// 在應用啓動的時候調用
+ (void)setupWithOptions:(NSDictionary *)launchOptions;

// 在appdelegate註冊設備處調用
+ (void)registerDeviceToken:(NSData *)deviceToken;

// ios7以後，纔有completion，否則傳nil
+ (void)handleRemoteNotification:(NSDictionary *)userInfo completion:(void (^)(UIBackgroundFetchResult))completion;

// 顯示本地通知在最前面
+ (void)showLocalNotificationAtFront:(UILocalNotification *)notification;

下面就是測試一個推送功能了：

//
//  AppDelegate.m
//  JPushDemo
//
//  Created by 黃儀標 on 14/11/20.
//  Copyright (c) 2014年 黃儀標. All rights reserved.
//

#import "AppDelegate.h"
#import "JPushHelper/HYBJPushHelper.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
  // Override point for customization after application launch.

  [HYBJPushHelper setupWithOptions:launchOptions];

  self.window.backgroundColor = [UIColor whiteColor];
  [self.window makeKeyAndVisible];
  return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
  [HYBJPushHelper registerDeviceToken:deviceToken];
  return;
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
  [HYBJPushHelper handleRemoteNotification:userInfo completion:nil];
  return;
}

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_7_0
// ios7.0以後纔有此功能
- (void)application:(UIApplication *)application didReceiveRemoteNotification
                   :(NSDictionary *)userInfo fetchCompletionHandler
                   :(void (^)(UIBackgroundFetchResult))completionHandler {
  [HYBJPushHelper handleRemoteNotification:userInfo completion:completionHandler];

  // 應用正處理前臺狀態下，不會收到推送消息，因此在此處需要額外處理一下
  if (application.applicationState == UIApplicationStateActive) {
   UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"收到推送消息"
                                                   message:userInfo[@"aps"][@"alert"]
                                                  delegate:nil
                                         cancelButtonTitle:@"取消"
                                         otherButtonTitles:@"確定", nil nil];
    [alert show];
  }
  return;
}
#endif

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
  [HYBJPushHelper showLocalNotificationAtFront:notification];
  return;
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
  NSLog(@"Error in registration. Error: %@", err);
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
  [application setApplicationIconBadgeNumber:0];
  return;
}

@end

真機運行，然後到官網去發一個通知，就可以收到了！

Good luck!
