极光推送

制作证书的过程详细看官方文档或者如下推荐：

创建完证书，就是去极光官网注册账号，创建应用,截图如下：

将创建的证书上传到应用上了，上传成功后的截图如下：

证书上传成功后，生成APP Key，截图如下：

好了，这下工作做完了，剩下的就是代码实现了：

第一步：下载SDK，将需要的两个文件导入项目中：

集成压缩包内容

包名为JPush-iOS-SDK-{版本号}

• lib文件夹：包含头文件 JPUSHService.h，静态库文件jpush-ios-x.x.x.a ，支持的iOS版本为 5.0 及以上版本。（请注意：模拟器不支持APNs）
• pdf文件：集成指南
• demo文件夹：示例

第二步：导入需要依赖的库文件：

必要的框架

• CFNetwork.framework
• CoreFoundation.framework
• CoreTelephony.framework
• SystemConfiguration.framework
• CoreGraphics.framework
• Foundation.framework
• UIKit.framework
• Security.framework
• Xcode7需要的是libz.tbd；Xcode7以下版本是libz.dylib
• Adsupport.framework (获取IDFA需要；如果不使用IDFA，请不要添加)

第三步：创建一个工具类，名称为KJJPushHelper，封装注册时的各种方法

.h

//
//  KJJPushHelper.h
//
//  Created by mac on 16/5/5.
//  Copyright © 2016年 mac. All rights reserved.
//

#import <Foundation/Foundation.h>

@interface KJJPushHelper : NSObject

// 在应用启动的时候调用
+ (void)setupWithOption:(NSDictionary *)launchingOption
                 appKey:(NSString *)appKey
                channel:(NSString *)channel
       apsForProduction:(BOOL)isProduction
  advertisingIdentifier:(NSString *)advertisingId;

// 在appdelegate注册设备处调用
+ (void)registerDeviceToken:(NSData *)deviceToken;

// ios7以后，才有completion，否则传nil
+ (void)handleRemoteNotification:(NSDictionary *)userInfo completion:(void (^)(UIBackgroundFetchResult))completion;

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

@end

.m

//  KJJPushHelper.m

//

#import "KJJPushHelper.h"
#import "JPUSHService.h"

@implementation KJJPushHelper

+ (void)setupWithOption:(NSDictionary *)launchingOption
                 appKey:(NSString *)appKey
                channel:(NSString *)channel
       apsForProduction:(BOOL)isProduction
  advertisingIdentifier:(NSString *)advertisingId{
    // Required
#if __IPHONE_OS_VERSION_MAX_ALLOWED > __IPHONE_7_1
    // ios8之后可以自定义category
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
        // 可以添加自定义categories
        [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                          UIUserNotificationTypeSound |
                                                          UIUserNotificationTypeAlert)
                                           categories:nil];
    } else {
#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_8_0
        // ios8之前 categories 必须为nil
        [JPUSHService registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                          UIRemoteNotificationTypeSound |
                                                          UIRemoteNotificationTypeAlert)
                                           categories:nil];
#endif
    }
#else
    // categories 必须为nil
    [JPUSHService registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                      UIRemoteNotificationTypeSound |
                                                      UIRemoteNotificationTypeAlert)
                                          categories:nil];
#endif
    
    // Required
    [JPUSHService setupWithOption:launchingOption appKey:appKey channel:channel apsForProduction:isProduction advertisingIdentifier:advertisingId];
    return;
}

+ (void)registerDeviceToken:(NSData *)deviceToken {
    [JPUSHService registerDeviceToken:deviceToken];
    return;
}

+ (void)handleRemoteNotification:(NSDictionary *)userInfo completion:(void (^)(UIBackgroundFetchResult))completion {
    [JPUSHService handleRemoteNotification:userInfo];
    
    if (completion) {
        completion(UIBackgroundFetchResultNewData);
    }
    return;
}

+ (void)showLocalNotificationAtFront:(UILocalNotification *)notification {
    [JPUSHService showLocalNotificationAtFront:notification identifierKey:nil];
    return;
}

@end

第四步：创建一个APPDelegate的分类，在该类中调用KJJPushHelper中的类方法

//  AppDelegate+KJJPushSDK.h
//
//  Created by mac on 16/5/5.
//  Copyright © 2016年 mac. All rights reserved.
//

#import "AppDelegate.h"

@interface AppDelegate (KJJPushSDK)
-(void)JPushApplication:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;
@end



//  AppDelegate+KJJPushSDK.m
//
//  Created by mac on 16/5/5.
//  Copyright © 2016年 mac. All rights reserved.
//

#import "AppDelegate+KJJPushSDK.h"
#import "KJJPushHelper.h"

#define JPushSDK_AppKey  @"31e01f6a2f6d4b1209061aec"
#define isProduction     NO

@implementation AppDelegate (KJJPushSDK)
-(void)JPushApplication:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
  
    [KJJPushHelper setupWithOption:launchOptions appKey:JPushSDK_AppKey channel:nil apsForProduction:isProduction advertisingIdentifier:nil];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Required - 注册 DeviceToken
    [KJJPushHelper registerDeviceToken:deviceToken];
}


- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    
    // Required,For systems with less than or equal to iOS6
    [KJJPushHelper handleRemoteNotification:userInfo completion:nil];
}


- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    
    // IOS 7 Support Required
    [KJJPushHelper handleRemoteNotification:userInfo completion:completionHandler];
    
    // 应用正处理前台状态下，不会收到推送消息，因此在此处需要额外处理一下
    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:@"确定",nil];
        [alert show];
    }
}


- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    //Optional
    NSLog(@"did Fail To Register For Remote Notifications With Error: %@", error);
}


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

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

@end

第五步：在AppDelegate中注册即可

//注册极光推送
[self JPushApplication:application didFinishLaunchingWithOptions:launchOptions];

好了，大功告成，插上真机运行：打印结果如下

如果出现下列错误信息JPUSH | W - [JPUSHClientController] Not get deviceToken yet. Maybe: your certificate not configured APNs? or current network is not so good so APNs registration failed? or there is no APNs register code? Please refer to JPush docs.

修改方法：

由于项目之前用到了环信SDK，环信得已经注册了通知，在AppDelegate中注册通知，didRegisterForRemoteNotificationsWithDeviceToken与didFailToRegisterForRemoteNotificationsWithError方法，均不执行。。。需到环信注册通知的地方，再次注册极光通知。方可以获取到Token执行。
