自己使用的一些经验，为了方便直接从这里复制过去就行。
就当做个笔记，防止长时间忘记之后，还需要去官网看文档。

主要思路： sdk文件 + 三方依赖系统库 + 头文件 + 添加代理 + 初始化代码

1.版本信息

• JPush : 2.2.0
• Xcode : 8.3.3
• iOS : 6.0 +

2.使用步骤

• 导入头文件

#import "JPUSHService.h"
// iOS10注册APNs所需头文件
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif

• 添加如下代码（支持版本为 iOS 6.0+）

#pragma mark -- JPush

/**
 注册apns
 */
- (void)registerAPNSWithOptions:(NSDictionary *)launchOptions{
    //Required
    //notice: 3.0.0及以后版本注册可以这样写，也可以继续用之前的注册方式
    JPUSHRegisterEntity * entity = [[JPUSHRegisterEntity alloc] init];
    entity.types = UNAuthorizationOptionAlert|UNAuthorizationOptionBadge|UNAuthorizationOptionSound;
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
        // 可以添加自定义categories
        // NSSet<UNNotificationCategory *> *categories for iOS10 or later
        // NSSet<UIUserNotificationCategory *> *categories for iOS8 and iOS9
    }
    [JPUSHService registerForRemoteNotificationConfig:entity delegate:self];
    
    // Required
    // init Push
    // notice: 2.1.5版本的SDK新增的注册方法，改成可上报IDFA，如果没有使用IDFA直接传nil
    // 如需继续使用pushConfig.plist文件声明appKey等配置内容，请依旧使用[JPUSHService setupWithOption:launchOptions]方式初始化。
    [JPUSHService setupWithOption:launchOptions appKey:@"2c6034060b406cfe94d4e2e2"
                          channel:@"App Store"
                 apsForProduction:YES
            advertisingIdentifier:nil];
    
    
    NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter];
    [defaultCenter addObserver:self selector:@selector(networkDidReceiveMessage:) name:kJPFNetworkDidReceiveMessageNotification object:nil];
    
}
/**
 极光推送消息处理
 
 @param notification 极光推送通知
 */
- (void)networkDidReceiveMessage:(NSNotification *)notification {
    
    NSDictionary * userInfo = [notification userInfo];
    NSString *content = [userInfo valueForKey:@"content"];
    NSDictionary *extras = [userInfo valueForKey:@"extras"];
    NSString *customizeField1 = [extras valueForKey:@"customizeField1"]; //服务端传递的Extras附加字段，key是自己定义的
    
}



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

#pragma mark- JPUSHRegisterDelegate

// iOS 10 Support
- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(NSInteger))completionHandler {
    // Required
    NSDictionary * userInfo = notification.request.content.userInfo;
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        [JPUSHService handleRemoteNotification:userInfo];
    }
    completionHandler(UNNotificationPresentationOptionAlert); // 需要执行这个方法，选择是否提醒用户，有Badge、Sound、Alert三种类型可以选择设置
}

// iOS 10 Support
- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
    // Required
    NSDictionary * userInfo = response.notification.request.content.userInfo;
    if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        [JPUSHService handleRemoteNotification:userInfo];
    }
    completionHandler();  // 系统要求执行这个方法
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    
    NSString *content = [userInfo valueForKey:@"content"];
    NSDictionary *extras = [userInfo valueForKey:@"extras"];
    NSString *customizeField1 = [extras valueForKey:@"customizeField1"];
    
    NSLog(@"content --- %@",content);
    NSLog(@"extras --- %@",extras);
    NSLog(@"customizeField1 --- %@",customizeField1);
    
    // Required, iOS 7 Support
    [JPUSHService handleRemoteNotification:userInfo];
    completionHandler(UIBackgroundFetchResultNewData);
}

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

#pragma mark -- JPush

• 添加依赖库文件

3.其他配置

• 在 JPush 官网注册应用，记住对应的Appkey，

代码中注册的时候使用。

Snip20170728_2.png

• 证书配置

直接导出调试推送证书 和 发布推送证书 的 .12 文件上传到JPush 官网。

• 开放App的后台能力 和 推送能力
