ios10推送(http://www.cnblogs.com/oc-bowen/p/6061280.html)

3、 推送的注冊

第一步: 導入 #import且要遵守的協議，在Appdelegate.m中。這里需要注意，我們最好寫成這種形式（防止低版本找不到頭文件出現問題）#ifdef NSFoundationVersionNumber_iOS_9_x_Max#import#endif

第二步：我們需要在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中注冊通知，代碼如下

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

[self replyPushNotificationAuthorization:application];

return YES;

}

#pragma mark - 申請通知權限

// 申請通知權限

- (void)replyPushNotificationAuthorization:(UIApplication *)application{

if (IOS10_OR_LATER) {

//iOS 10 later

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];

//必須寫代理，不然無法監聽通知的接收與點擊事件

center.delegate = self;

[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {

if (!error && granted) {

//用戶點擊允許

NSLog(@"注冊成功");

}else{

//用戶點擊不允許

NSLog(@"注冊失敗");

}

}];

// 可以通過 getNotificationSettingsWithCompletionHandler 獲取權限設置

//之前注冊推送服務，用戶點擊了同意還是不同意，以及用戶之后又做了怎樣的更改我們都無從得知，現在 apple 開放了這個 API，我們可以直接獲取到用戶的設定信息了。注意UNNotificationSettings是只讀對象哦，不能直接修改！

[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {

NSLog(@"========%@",settings);

}];

}else if (IOS8_OR_LATER){

//iOS 8 - iOS 10系統

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];

[application registerUserNotificationSettings:settings];

}else{

//iOS 8.0系統以下

[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];

}

//注冊遠端消息通知獲取device token

[application registerForRemoteNotifications];

}

上面需要注意：1. 必須寫代理，不然無法監聽通知的接收與點擊事件 center.delegate = self;下面是我在項目里定義的宏#define IOS10_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0)#define IOS9_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9.0)#define IOS8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)#define IOS7_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)2. 之前注冊推送服務，用戶點擊了同意還是不同意，以及用戶之后又做了怎樣的更改我們都無從得知，現在 apple 開放了這個 API，我們可以直接獲取到用戶的設定信息了。注意UNNotificationSettings是只讀對象哦，不能直接修改！只能通過以下方式獲取 [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {? ? ? ? ? ? NSLog(@"========%@",settings);? }];打印信息如下：========4、 遠端推送需要獲取設備的Device Token的方法是沒有變的,代碼如下

#pragma? mark - 獲取device Token

//獲取DeviceToken成功

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{

//解析NSData獲取字符串

//我看網上這部分直接使用下面方法轉換為string，你會得到一個nil（別怪我不告訴你哦）

//錯誤寫法

//NSString *string = [[NSString alloc] initWithData:deviceToken encoding:NSUTF8StringEncoding];

//正確寫法

NSString *deviceString = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];

deviceString = [deviceString stringByReplacingOccurrencesOfString:@" " withString:@""];

NSLog(@"deviceToken===========%@",deviceString);

}

//獲取DeviceToken失敗

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{

NSLog(@"[DeviceToken Error]:%@\n",error.description);

}

5、這一步吊了，這是iOS 10系統更新時，蘋果給了我們2個代理方法來處理通知的接收和點擊事件，這兩個方法在的協議中，大家可以查看下。@protocol UNUserNotificationCenterDelegate@optional

// The method will be called on the delegate only if the application is in the foreground. If the method is not implemented or the handler is not called in a timely manner then the notification will not be presented. The application can choose to have the notification presented as a sound, badge, alert and/or in the notification list. This decision should be based on whether the information in the notification is otherwise visible to the user.

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler __IOS_AVAILABLE(10.0) __TVOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0);

// The method will be called on the delegate when the user responded to the notification by opening the application, dismissing the notification or choosing a UNNotificationAction. The delegate must be set before the application returns from applicationDidFinishLaunching:.

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler __IOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0) __TVOS_PROHIBITED;

@end

此外，蘋果把本地通知跟遠程通知合二為一。區分本地通知跟遠程通知的類是UNPushNotificationTrigger.h類中，UNPushNotificationTrigger的類型是新增加的，通過它，我們可以得到一些通知的觸發條件 ，解釋如下：

UNPushNotificationTrigger （遠程通知） 遠程推送的通知類型

UNTimeIntervalNotificationTrigger （本地通知） 一定時間之后，重復或者不重復推送通知。我們可以設置timeInterval（時間間隔）和repeats（是否重復）。

UNCalendarNotificationTrigger（本地通知） 一定日期之后，重復或者不重復推送通知 例如，你每天8點推送一個通知，只要dateComponents為8，如果你想每天8點都推送這個通知，只要repeats為YES就可以了。

UNLocationNotificationTrigger （本地通知）地理位置的一種通知，

當用戶進入或離開一個地理區域來通知。

現在先提出來，后面我會一一代碼演示出每種用法。還是回到兩個很吊的代理方法吧

#pragma mark - iOS10 收到通知（本地和遠端） UNUserNotificationCenterDelegate

//App處于前臺接收通知時

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{

//收到推送的請求

UNNotificationRequest *request = notification.request;

//收到推送的內容

UNNotificationContent *content = request.content;

//收到用戶的基本信息

NSDictionary *userInfo = content.userInfo;

//收到推送消息的角標

NSNumber *badge = content.badge;

//收到推送消息body

NSString *body = content.body;

//推送消息的聲音

UNNotificationSound *sound = content.sound;

// 推送消息的副標題

NSString *subtitle = content.subtitle;

// 推送消息的標題

NSString *title = content.title;

if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {

//此處省略一萬行需求代碼。。。。。。

NSLog(@"iOS10 收到遠程通知:%@",userInfo);

}else {

// 判斷為本地通知

//此處省略一萬行需求代碼。。。。。。

NSLog(@"iOS10 收到本地通知:{\\\\nbody:%@，\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge：%@，\\\\nsound：%@，\\\\nuserInfo：%@\\\\n}",body,title,subtitle,badge,sound,userInfo);

}

// 需要執行這個方法，選擇是否提醒用戶，有Badge、Sound、Alert三種類型可以設置

completionHandler(UNNotificationPresentationOptionBadge|

UNNotificationPresentationOptionSound|

UNNotificationPresentationOptionAlert);

}

//App通知的點擊事件

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{

//收到推送的請求

UNNotificationRequest *request = response.notification.request;

//收到推送的內容

UNNotificationContent *content = request.content;

//收到用戶的基本信息

NSDictionary *userInfo = content.userInfo;

//收到推送消息的角標

NSNumber *badge = content.badge;

//收到推送消息body

NSString *body = content.body;

//推送消息的聲音

UNNotificationSound *sound = content.sound;

// 推送消息的副標題

NSString *subtitle = content.subtitle;

// 推送消息的標題

NSString *title = content.title;

if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {

NSLog(@"iOS10 收到遠程通知:%@",userInfo);

//此處省略一萬行需求代碼。。。。。。

}else {

// 判斷為本地通知

//此處省略一萬行需求代碼。。。。。。

NSLog(@"iOS10 收到本地通知:{\\\\nbody:%@，\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge：%@，\\\\nsound：%@，\\\\nuserInfo：%@\\\\n}",body,title,subtitle,badge,sound,userInfo);

}

//2016-09-27 14:42:16.353978 UserNotificationsDemo[1765:800117] Warning: UNUserNotificationCenter delegate received call to -userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: but the completion handler was never called.

completionHandler(); // 系統要求執行這個方法

}

需要注意的：

1.下面這個代理方法，只會是app處于前臺狀態 前臺狀態 and 前臺狀態下才會走，后臺模式下是不會走這里的

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler

2.下面這個代理方法，只會是用戶點擊消息才會觸發，如果使用戶長按（3DTouch）、彈出Action頁面等并不會觸發。點擊Action的時候會觸發！

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler

3.點擊代理最后需要執行：completionHandler(); // 系統要求執行這個方法

不然會報：

2016-09-27 14:42:16.353978 UserNotificationsDemo[1765:800117] Warning: UNUserNotificationCenter delegate received call to -userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: but the completion handler was never called.

4.不管前臺后臺狀態下。推送消息的橫幅都可以展示出來！后臺狀態不用說，前臺時需要在前臺代理方法中設置 ，設置如下：

// 需要執行這個方法，選擇是否提醒用戶，有Badge、Sound、Alert三種類型可以設置

completionHandler(UNNotificationPresentationOptionBadge|

UNNotificationPresentationOptionSound|

UNNotificationPresentationOptionAlert);

6、 iOS 10之前接收通知的兼容方法

#pragma mark -iOS 10之前收到通知

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

NSLog(@"iOS6及以下系統，收到通知:%@", userInfo);

//此處省略一萬行需求代碼。。。。。。

}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

NSLog(@"iOS7及以上系統，收到通知:%@", userInfo);

completionHandler(UIBackgroundFetchResultNewData);

//此處省略一萬行需求代碼。。。。。。

}
