篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了iOS10通知及通知拓展Extension使用详解（附Demo）相关的知识，希望对你有一定的参考价值。
1.1-iOS10拓展简介
iOS10系统最大的一个亮点就是增加了系统应用的拓展功能
Extension- Extension功能可以理解为自定义系统界面
本小节我们就以自定义系统通知界面来学习一下
Extension的使用- 其他功能的
Extension我们不可能逐一讲解，希望大家能够在理解的基础上，做到举一反三
- 其他功能的
1.2-iOS10通知使用
iOS10之后，为了对自定义通知界面拓展
Notification Content的支持，iOS系统推出了新的框架<UserNotifications>- 通知的使用思路和步骤不变，只是API发生了变化，并且系统全部会有提示，我们只需要根据系统提示修改一下即可
1.请求授权及添加分类
#import "AppDelegate.h"
//iOS10通知新框架
#import <UserNotifications/UserNotifications.h>
//iOS10 自定义通知界面
#import <UserNotificationsUI/UserNotificationsUI.h>
@interface AppDelegate ()<UNUserNotificationCenterDelegate>
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//申请授权
//1.创建通知中心
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//设置通知中心的代理（iOS10之后监听通知的接收时间和交互按钮的响应是通过代理来完成的）
center.delegate = self;
//2.通知中心设置分类
[center setNotificationCategories:[NSSet setWithObjects:[self createCatrgory], nil]];
//3.请求授权
/**UNAuthorizationOption
UNAuthorizationOptionBadge = (1 << 0),红色圆圈
UNAuthorizationOptionSound = (1 << 1),声音
UNAuthorizationOptionAlert = (1 << 2),内容
UNAuthorizationOptionCarPlay = (1 << 3),车载通知
*/
[center requestAuthorizationWithOptions:UNAuthorizationOptionAlert|UNAuthorizationOptionBadge|UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
NSLog(@"授权成功");
}
}];
return YES;
}
//当APP处于前台的时候接收到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
//弹出一个网页
UIWebView *webview = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 400, 500)];
webview.center = self.window.center;
[webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.itheima.com"]]];
[self.window addSubview:webview];
//弹出动画
webview.alpha = 0;
[UIView animateWithDuration:1 animations:^{
webview.alpha = 1;
}];
}
#pragma mark - 创建通知分类（交互按钮）
- (UNNotificationCategory *)createCatrgory
{
//文本交互(iOS10之后支持对通知的文本交互)
/**options
UNNotificationActionOptionAuthenticationRequired 用于文本
UNNotificationActionOptionForeground 前台模式，进入APP
UNNotificationActionOptionDestructive 销毁模式，不进入APP
*/
UNTextInputNotificationAction *textInputAction = [UNTextInputNotificationAction actionWithIdentifier:@"textInputAction" title:@"请输入信息" options:UNNotificationActionOptionAuthenticationRequired textInputButtonTitle:@"输入" textInputPlaceholder:@"还有多少话要说……"];
//打开应用按钮
UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"foreGround" title:@"打开" options:UNNotificationActionOptionForeground];
//不打开应用按钮
UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:@"backGround" title:@"关闭" options:UNNotificationActionOptionDestructive];
//创建分类
/**
Identifier:分类的标识符，通知可以添加不同类型的分类交互按钮
actions：交互按钮
intentIdentifiers：分类内部标识符 没什么用 一般为空就行
options:通知的参数 UNNotificationCategoryOptionCustomDismissAction:自定义交互按钮 UNNotificationCategoryOptionAllowInCarPlay:车载交互
*/
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"category" actions:@[textInputAction,action1,action2] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
return category;
}
//按钮点击事件
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
//根据identifer判断按钮类型，如果是textInput则获取输入的文字
if ([response.actionIdentifier isEqualToString:@"textInputAction"]) {
//获取文本响应
UNTextInputNotificationResponse *textResponse = (UNTextInputNotificationResponse *)response;
NSLog(@"输入的内容为：%@",textResponse.userText);
}
//处理其他时间
NSLog(@"%@",response.actionIdentifier);
}
- (void)applicationWillResignActive:(UIApplication *)application {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
- (void)applicationWillTerminate:(UIApplication *)application {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
@end
- 2.发送通知（含分类交互按钮）
#pragma mark - 发送本地通知
- (IBAction)sendLocalNotification:(id)sender {
//1.创建通知中心
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//2.检查当前用户授权
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
NSLog(@"当前授权状态：%zd",[settings authorizationStatus]);
//3.创建通知
UNMutableNotificationContent *notification = [[UNMutableNotificationContent alloc] init];
//3.1通知标题
notification.title = [NSString localizedUserNotificationStringForKey:@"传智播客" arguments:nil];
//3.2小标题
notification.subtitle = @"hellow world";
//3.3通知内容
notification.body = @"欢迎来到黑马程序员";
//3.4通知声音
notification.sound = [UNNotificationSound defaultSound];
//3.5通知小圆圈数量
notification.badge = @2;
//4.创建触发器(相当于iOS9中通知触发的时间)
/**通知触发器主要有三种
UNTimeIntervalNotificationTrigger 指定时间触发
UNCalendarNotificationTrigger 指定日历时间触发
UNLocationNotificationTrigger 指定区域触发
*/
UNTimeIntervalNotificationTrigger * timeTrigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:NO];
//5.指定通知的分类 (1)identifer表示创建分类时的唯一标识符 （2）该代码一定要在创建通知请求之前设置，否则无效
notification.categoryIdentifier = @"category";
//给通知添加附件(图片 音乐 电影都可以)
NSString *path = [[NSBundle mainBundle] pathForResource:@"logo" ofType:@"png"];
UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:@"image" URL:[NSURL fileURLWithPath:path] options:nil error:nil];
notification.attachments = @[attachment];
//7.创建通知请求
/**
Identifier:通知请求标识符，用于删除或者查找通知
content：通知的内容
trigger：通知触发器
*/
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"localNotification" content:notification trigger:timeTrigger];
//8.通知中心发送通知请求
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (error == nil) {
NSLog(@"通知发送成功");
}
else
{
NSLog(@"%@",error);
}
}];
}];
}
- 3.通知的移除
#pragma mark - 移除所有通知
- (IBAction)removeAllNotification:(id)sender {
//1.创建通知中心
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//2.删除已经推送过得通知
[center removeAllDeliveredNotifications];
//3.删除未推送的通知请求
[center removeAllPendingNotificationRequests];
}
#pragma mark - 移除指定通知
- (IBAction)removeSingleNotification:(id)sender {
//1.创建通知中心
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//2.删除指定identifer的已经发送的通知
[center removeDeliveredNotificationsWithIdentifiers:@[@"localNotification"]];
//3.删除指定identifer未发送的同志请求
[center removeDeliveredNotificationsWithIdentifiers:@[@"localNotification"]];
}
1.3-iOS10通知拓展Extension使用
- 1.添加通知拓展
- 2.通知的拓展Extension实际上相当于在当前的应用程序重新添加一个应用程序，工程会添加对应的代码文件夹和target
- 3.默认拓展控制器只有一个Label，我们可以在这里自定义我们的控制器界面
- 4.也可以加载通知中推送的数据
- 5.配置plist文件
- 默认情况下应用程序是不会加载拓展界面的，需要配置plist文件，关闭系统默认通知界面
- 6.运行
- 运行的话不需要选择
Extension的target，直接选择应用程序的target即可
- 运行的话不需要选择
