iOS10New push function implementation code

From iOS8Starting from iOS version .0, the implementation of push features is constantly changing, and the functions are also increasing, iOS10Another push plugin development has emerged (see the last figure), no more words, let's go straight to the code:　

#import <UserNotifications/UserNotifications.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 // Override point for customization after the application launch.
 /* In the case of the APP not running and clicking the push message, iOS10Abandon the use of UIApplicationLaunchOptionsLocalNotificationKey, use the UNUserNotificationCenterDelegate method didReceiveNotificationResponse:withCompletionHandler: to get local push notifications
 */
// NSDictionary *localUserInfo = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];
// if (localUserInfo) {
// NSLog(@"localUserInfo:%@",localUserInfo);
// //The APP is not running, click the push message
// }
 NSDictionary *remoteUserInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
 if (remoteUserInfo) {
 NSLog(@"remoteUserInfo:%@",remoteUserInfo);
 //The APP is not running, click the push message, iOS10is still the same as before, get here
 }
 [self registerNotification];
 return YES;
}

New library #import <UserNotifications/UserNotifications.h> Push single column UNUserNotificationCenter and other APIs　

- (void)registerNotification{
 /*
 identifier: The action identifier, used to identify which action is called when the proxy method is invoked.
 title: The name of the action.
 UIUserNotificationActivationMode: Whether the action opens the APP.
 authenticationRequired: Whether it is necessary to unlock.
 destructive: This determines the button display color, YES means the button will be red.
 behavior: Clicking the button text input, whether the keyboard pops up
 */
 UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action"1" title:@"Strategy"1behavior1" options:UNNotificationActionOptionForeground];
 /*iOS9Implementation method
 UIMutableUserNotificationAction * action1 [[UIMutableUserNotificationAction alloc] init];
 action1.identifier = @"action"}1";
 action1.title=@"Strategy1behavior1";
 action1.activationMode = UIUserNotificationActivationModeForeground;
 action1.destructive = YES;
 */
 UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action"2" title:@"Strategy"1behavior2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"textInputButtonTitle" textInputPlaceholder:@"textInputPlaceholder"];
 /*iOS9Implementation method

 action2.activationMode = UIUserNotificationActivationModeBackground;
 action2.authenticationRequired = NO;
 action2.destructive = NO;
 action2.behavior = UIUserNotificationActionBehaviorTextInput;//Clicking the button text input, whether the keyboard pops up
 */
 UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"Category1" actions:@[action2,action1] minimalActions:@[action2,action1] intentIdentifiers:@[@"action1",@"action2] options:UNNotificationCategoryOptionCustomDismissAction];
 // UIMutableUserNotificationCategory * category1 = [[UIMutableUserNotificationCategory alloc] init];
 // category1.identifier = @"Category1";
 // [category1 setActions:@[action2,action1] forContext:(UIUserNotificationActionContextDefault)];
 UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action"3" title:@"Strategy"2behavior1" options:UNNotificationActionOptionForeground];
 // UIMutableUserNotificationAction * action3 [[UIMutableUserNotificationAction alloc] init];
 // action3.identifier = @"action"}3";
 // action3.title=@"Strategy2behavior1";
 // action3.activationMode = UIUserNotificationActivationModeForeground;
 // action3.destructive = YES;
 UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action"4" title:@"Strategy"2behavior2" options:UNNotificationActionOptionForeground];
 // UIMutableUserNotificationAction * action4 [[UIMutableUserNotificationAction alloc] init];
 // action4.identifier = @"action"}4";
 // action4.title=@"Strategy2behavior2";
 // action4.activationMode = UIUserNotificationActivationModeBackground;
 // action4.authenticationRequired = NO;
 // action4.destructive = NO;
 UNNotificationCategory *category2 = [UNNotificationCategory categoryWithIdentifier:@"Category2" actions:@[action3,action4] minimalActions:@[action3,action4] intentIdentifiers:@[@"action3",@"action4] options:UNNotificationCategoryOptionCustomDismissAction];
 // UIMutableUserNotificationCategory * category2 = [[UIMutableUserNotificationCategory alloc] init];

 // [category2 setActions:@[action4,action3] forContext:(UIUserNotificationActionContextDefault)];
 [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1,category2, nil]];
 [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
 
 }]
 /*iOS9Implementation method
 UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObjects: category1,category2, nil]];
 [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
 */
 [[UIApplication sharedApplication] registerForRemoteNotifications];
 [UNUserNotificationCenter currentNotificationCenter].delegate = self;
}

Change of delegate method:

　Some local and remote push notifications callbacks are placed in the same delegate method

#pragma mark -
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED{
 NSLog(@"didRegisterUserNotificationSettings");

　There is also push plugin development: similar to iOS tody widget plugin development
