Objective-C:
1、在项目 target 中，打开Capabilitie —> Push Notifications，并会自动在项目中生成 .entitlement 文件。（很多同学升级后，获取不到 deviceToken，大概率是由于没开这个选项）Capabilitie —> Push Notifications自动生成 .entitlement
2、确保添加了 UserNotifications.framework，并 import到 AppDelegate，记得实现 UNUserNotificationCenterDelegate 。
#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder<UIApplicationDelegate,UNUserNotificationCenterDelegate>
@end
3、在 didFinishLaunchingWithOptions 方法中，首先实现 UNUserNotificationCenter delegate，并使用 UIUserNotificationSettings 请求权限。
//注意，关于 iOS10 系统版本的判断，可以用下面这个宏来判断。不能再用截取字符的方法。
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
if( !error ){
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
}
return YES;
}
4、最后实现以下两个回调。
//====================For iOS 10====================
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(@"Userinfo %@",notification.request.content.userInfo);
//功能：可设置是否在应用内弹出通知
completionHandler(UNNotificationPresentationOptionAlert);
}
//点击推送消息后回调
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(@"Userinfo %@",response.notification.request.content.userInfo);
}
注意：需要根据系统版本号来判断是否使用新的 UserNotifications.framework，因此，不要着急删除 iOS 10 以前的代码。
swift:
判断iOS版本号方法：
func checkiOSVersion(version:String) -> Bool{
let iosversion : NSString = UIDevice.currentDevice().systemVersion
if (iosversion.compare(version, options: NSStringCompareOptions.NumericSearch) != NSComparisonResult.OrderedAscending) {
return true
}
return false
}
