以下是iOS8~iOS10注册本地通知方式
- iOS8-10注册本地通知方式一样
- 以下我在程序启动注册本地通知,iOS8模拟器上
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// 判断系统版本号是否小于10.0
NSString *version = [UIDevice currentDevice].systemVersion;
if (version.doubleValue < 10.0) {
// 参数5是触发时间单位秒
[self registerLocalNotification:5];
}else{
// [self regisNoti];
}
return YES;
}
// 注册通知具体方法
- (void)registerLocalNotification:(NSInteger)alertTime {
UILocalNotification *notification = [[UILocalNotification alloc] init];
// 设置触发通知的时间
NSDate *fireDate = [NSDate dateWithTimeIntervalSinceNow:alertTime];
NSLog(@"fireDate=%@",fireDate);
notification.fireDate = fireDate;
// 时区
notification.timeZone = [NSTimeZone defaultTimeZone];
// 设置重复的间隔
notification.repeatInterval = kCFCalendarUnitSecond;
// 通知内容
notification.alertBody = @"该起床了...";
notification.applicationIconBadgeNumber = 1;
// 通知被触发时播放的声音
notification.soundName = UILocalNotificationDefaultSoundName;
// 通知参数
NSDictionary *userDict = [NSDictionary dictionaryWithObject:@"开始学习iOS开发了" forKey:@"key"];
notification.userInfo = userDict;
// ios8后，需要添加这个注册，才能得到授权
if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
UIUserNotificationType type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type
categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
// 通知重复提示的单位，可以是天、周、月
notification.repeatInterval = NSCalendarUnitDay;
} else {
// 通知重复提示的单位，可以是天、周、月
notification.repeatInterval = NSCalendarUnitDay;
}
// 执行通知注册
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { NSLog(@"noti:%@",notification) 此方法是在程序在前台接收到本地通知,或者在后台接收到通知并点击通知横幅会调用
#pragma mark - 本地通知回调
// 本地通知回调函数，当应用程序在前台接收到通知,或者后台点击通知调用
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
NSLog(@"noti:%@",notification);
// 这里真实需要处理交互的地方
// 获取通知所带的数据
NSString *notMess = [notification.userInfo objectForKey:@"key"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"本地通知(前台)"
message:notMess
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
// 更新显示的badge个数
NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
badge--;
badge = badge >= 0 ? badge : 0;
[UIApplication sharedApplication].applicationIconBadgeNumber = badge;
// 在不需要再推送时，可以取消某一个推送(或者可以取消全部本地通知)
[self cancelLocalNotificationWithKey:@"key"];
}
// 判断程序是在前台还是后台
- (void)applicationDidEnterBackground:(UIApplication *)application
{
//进入后台
NSLog(@"后台");
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// app启动或者app从后台进入前台都会调用这个方法
NSLog(@"前台");
// 更新显示的badge个数,每次进入我都设置为0
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}
#pragma mark - 取消某个(或者全部)本地推送通知
- (void)cancelLocalNotificationWithKey:(NSString *)key {
// 获取所有本地通知数组
NSArray *localNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;
for (UILocalNotification *notification in localNotifications) {
NSDictionary *userInfo = notification.userInfo;
if (userInfo) {
// 根据设置通知参数时指定的key来获取通知参数
NSString *info = userInfo[key];
// 如果找到需要取消的通知，则取消
if (info != nil) {
[[UIApplication sharedApplication] cancelLocalNotification:notification];
// 取消所有本地通知
// [[UIApplication sharedApplication] cancelAllLocalNotifications];
break;
}
}
}
}
以下是iOS10以后注册本地通知
- 注册通知方法,另外需要设置代理
UNUserNotificationCenterDelegate以及导入头文件#import <UserNotifications/UserNotifications.h>
#pragma mark - iOS 10以上设置通知
-(void)regisNoti{
// 使用 UNUserNotificationCenter 来管理通知
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//监听回调事件
center.delegate = self;
//iOS 10 使用以下方法注册，才能得到授权，注册通知以后，会自动注册 deviceToken，如果获取不到 deviceToken，Xcode8下要注意开启 Capability->Push Notification。
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
// Enable or disable features based on authorization.
}];
//获取当前的通知设置，UNNotificationSettings 是只读对象，不能直接修改，只能通过以下方法获取
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
}];
[self pushLocalNotifactionWithFireTime:5];
}
}
// 发送通知具体方法
-(void)pushLocalNotifactionWithFireTime:(NSInteger)alerTime{
// 使用 UNUserNotificationCenter 来管理通知
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
//需创建一个包含待通知内容的 UNMutableNotificationContent 对象，注意不是 UNNotificationContent ,此对象为不可变对象。
UNMutableNotificationContent* content = [[UNMutableNotificationContent alloc] init];
content.title = [NSString localizedUserNotificationStringForKey:@"Hello!" arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:@"Hello_message_body"
arguments:nil];
content.sound = [UNNotificationSound defaultSound];
content.userInfo = @{
@"a":@"v",
@"c":@"d",
};
// 在 alertTime 后推送本地推送
UNTimeIntervalNotificationTrigger* trigger = [UNTimeIntervalNotificationTrigger
triggerWithTimeInterval:alerTime repeats:NO];
UNNotificationRequest* request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond"
content:content trigger:trigger];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
}];
}
}
- 实现iOS10本地通知代理方法
- 与iOS8不同的是,iOS10本地通知在前台与在后台触发通知调用的代理方法不一样如下:
#pragma mark - delegate iOS10
// 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.
// 前台调用
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler __IOS_AVAILABLE(10.0) __TVOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0){
NSLog(@"1--title---%@", notification.request.content.title);
NSLog(@"2--subtitle---%@", notification.request.content.subtitle);
NSLog(@"3--userInfo---%@", notification.request.content.userInfo);
NSLog(@"4--body---%@", notification.request.content.body);
}
// 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 application:didFinishLaunchingWithOptions:.
// 后台点击通知后调用
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler __IOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0) __TVOS_PROHIBITED{
NSLog(@"7--title---%@", response.notification.request.content.title);
NSLog(@"8--subtitle---%@", response.notification.request.content.subtitle);
NSLog(@"9--userInfo---%@", response.notification.request.content.userInfo);
NSLog(@"10--body---%@", response.notification.request.content.body);
}
