iOS10实现推送功能时的注意点和问题总结

#import <UserNotifications/UserNotifications.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
@end

//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;
}

//====================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);
}
