ios10中未触发本地通知 [英] Local notifications are not firing in ios10
本文介绍了ios10中未触发本地通知的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在为ios 10使用 UNUserNotificationCenter
。对于测试,我从当前时间开始设置本地通知10秒。
I'm using UNUserNotificationCenter
for ios 10. For testing, I'm setting a local notification for 10 seconds from current time.
这是我试过的,
- (void)viewDidLoad {
[super viewDidLoad];
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(@"request succeeded!");
[self set10Notifs];
}
}];
}
-(void) set10Notifs
{
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {
#if XCODE_VERSION_GREATER_THAN_OR_EQUAL_TO_8
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDateComponents *components = [calendar components:NSCalendarUnitTimeZone fromDate:[[NSDate date] dateByAddingTimeInterval:10]];
UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@"Prayer!" arguments:nil];
objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@"Time now"
arguments:nil];
objNotificationContent.sound = [UNNotificationSound defaultSound];
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"Prayer"
content:objNotificationContent trigger:trigger];
UNUserNotificationCenter *userCenter = [UNUserNotificationCenter currentNotificationCenter];
[userCenter addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (!error) {
NSLog(@"Local Notification succeeded");
}
else {
NSLog(@"Local Notification failed");
}
}];
#endif
}
}
我可以看到日志本地通知成功。但本地通知未在设备中触发。
I can see the log "Local Notification succeeded". But the local notification is not firing in the device.
在Appdelegate中,我添加了
In Appdelegate, I added
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
return YES;
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification
withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {
NSLog(@"Notification is triggered");
completionHandler(UNNotificationPresentationOptionBadge);
}
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(@"User Info : %@",response.notification.request.content.userInfo);
completionHandler();
}
我做错了什么?
为什么不解雇应用程序通知?
What did I do wrong? Why the app notifications not fired?
推荐答案
设置NSDateComponents,如:
Set NSDateComponents like:
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond|NSCalendarUnitTimeZone fromDate:[[NSDate date] dateByAddingTimeInterval:10]];
