输出 做了写总结之后才是自己的
// 注册通知
Appdelegate 中注册
#import <UserNotifications/UserNotifications.h>
[self registerAPN];
-(void)registerAPN{
// ios 10
if (@available(iOS 10.0, *)) { // iOS10 以上
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
}];
}else{
[self setUserNotifacationSettiings:[UIApplication sharedApplication]];
}
}
- (void)setUserNotifacationSettiings:(UIApplication *)application {
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
NSLog(@"接收到了通知== %@== %@",notification.alertBody,notification.alertTitle);
}
使用通知 发送通知 存在userdefaults 中是否打开 开关
- (void)setnotifactionsWithDate:(NSString*)date{
NSString *switchstr = [[NSUserDefaults standardUserDefaults]objectForKey:@"switch"];
if ([switchstr isEqualToString:@"on"]) {
[self setLocalnonification:date];
}
}
- (void)setLocalnonification:(NSString *)date{
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
// 标题
content.title = @"该写日记了";
content.subtitle = @"打开";
NSDateComponents *components = [[NSDateComponents alloc] init];
// 注意，weekday默认是从周日开始
NSArray *datearray = [date componentsSeparatedByString:@":" ];
components.hour = [datearray[0] integerValue];
components.minute = [datearray[1] integerValue];
UNCalendarNotificationTrigger *calendarTrigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];
NSString *identifier = @"noticeId";
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier content:content trigger:calendarTrigger];
[center addNotificationRequest:request withCompletionHandler:^(NSError *_Nullable error) {
NSLog(@"成功添加推送");
}];
}else{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
//设置时区（跟随手机的时区）
localNotification.timeZone = [NSTimeZone defaultTimeZone];
if (localNotification) {
localNotification.alertBody = @"该写日记了";
localNotification.alertAction = @"打开";
//小图标数字
localNotification.applicationIconBadgeNumber = 1;
date = [NSString stringWithFormat:@"%@:00",date];
localNotification.applicationIconBadgeNumber = 0;
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"HH:mm:ss"];
NSDate *dateda = [formatter dateFromString:date];
// [formatter dateFromString:@"22:15:50"];
//通知发出的时间
NSLog(@"----%@",dateda);
localNotification.fireDate = dateda;
// [NSDate dateWithTimeIntervalSinceNow:3];
// date;
}
//循环通知的周期
localNotification.repeatInterval = kCFCalendarUnitDay;
//设置userinfo方便撤销
NSDictionary *info = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];
localNotification.userInfo = info;
//启动任务
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
关闭的时候 在这里我用的是移出所有的通知 因为我在这个项目中只用到了本地写日记提醒这一个通知
- (void)cancelnotifaction{
// 移出所有的通知
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center removeAllPendingNotificationRequests];
}else {
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
// [[UIApplication sharedApplication] cancelAllLocalNotifications];
}
- (void)checkUserNotificationEnable { // 判断用户是否允许接收通知
if (@available(iOS 10.0, *)) {
__block BOOL isOn = NO;
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
if (settings.notificationCenterSetting == UNNotificationSettingEnabled) {
isOn = YES;
NSLog(@"打开了通知");
}else {
isOn = NO;
NSLog(@"关闭了通知");
[self showAlertView];
}
}];
}else {
if ([[UIApplication sharedApplication] currentUserNotificationSettings].types == UIUserNotificationTypeNone){
NSLog(@"关闭了通知");
[self showAlertView];
}else {
NSLog(@"打开了通知");
}
}
}
- (void)showAlertView {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"通知" message:@"未获得通知权限，请前去设置" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil]];
[alert addAction:[UIAlertAction actionWithTitle:@"设置" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[self goToAppSystemSetting];
}]];
[self presentViewController:alert animated:YES completion:nil];
}
// 如果用户关闭了接收通知功能，该方法可以跳转到APP设置页面进行修改
- (void)goToAppSystemSetting {
dispatch_async(dispatch_get_main_queue(), ^{
UIApplication *application = [UIApplication sharedApplication];
NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([application canOpenURL:url]) {
if (@available(iOS 10.0, *)) {
if ([application respondsToSelector:@selector(openURL:options:completionHandler:)]) {
[application openURL:url options:@{} completionHandler:nil];
}
}else {
[application openURL:url];
}
}
});
}
