我有这段代码用于每天中午发出本地通知:
//Get todays midnight
NSDate *alertTime = [NSDate date];
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSUInteger preservedComponents = (NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit);
alertTime = [calendar dateFromComponents:[calendar components:preservedComponents fromDate:alertTime]];
UIApplication *app = [UIApplication sharedApplication];
//Set up the local notification
UILocalNotification *notification = [[UILocalNotification alloc] init];
if(notification){
//Set fire date to alert time
notification.fireDate = alertTime;
//Set time zone to default
notification.timeZone = [NSTimeZone defaultTimeZone];
//Repeat the notification everyday (fires at same time
//as initial notification)
notification.repeatInterval = NSDayCalendarUnit;
// schedule notification
[app scheduleLocalNotification:notification];
NSLog(@"%@", notification.fireDate);
}
但是我需要在13:00每天发出另一个本地通知。这是如何完成的?我不明白上面的代码如何适应这个...
非常感谢,

如果你有时间每天发出通知,你应该这样做
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
for (NSMutableArray * arrDay in self.namaztimes) {
NSLog(@"Alarm Array: %@", arrDay);
int count=[arrDay count];
if(!count){
continue;
}
int day =0;
int month=0;
int year=0;
int hour =0;
int minutes=0;
// NSArray *arrDates=[[NSMutableArray alloc] initWithCapacity:1];
for ( int i=0;i<3;i++) {
NSString * dayTime=[arrDay objectAtIndex:i ];
if (i==0) {
day = [dayTime intValue];
}else if(i==1){
month = [dayTime intValue];
}else if(i==2){
year = [dayTime intValue];
}
}
for ( int i=3;i<count;i++) {
NSString * dayTime=[arrDay objectAtIndex:i ];
hour = [[dayTime substringToIndex:2] intValue];
minutes = [[dayTime substringFromIndex:3] intValue];
[components setDay:day];
[components setMonth:month];
[components setYear:year];
[components setMinute:minutes];
[components setHour:hour];
NSDate *myNewDate = [calendar dateFromComponents:components];
[self scheduleNotificationForDate:myNewDate];
}
}
[components release];
[calendar release];
然后从这里它将连接到主要通知点火方法
[self scheduleNotificationForDate:myNewDate];
-(void) scheduleNotificationForDate: (NSDate*)date {
/* Here we cancel all previously scheduled notifications */
[[UIApplication sharedApplication] cancelAllLocalNotifications];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = date;
NSLog(@"Notification will be shown on: %@ ",localNotification.fireDate);
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = @"Your Notification Text"; //[NSString stringWithFormat:@"%@",date];
localNotification.alertAction = NSLocalizedString(@"View details", nil);
/* Here we set notification sound and badge on the app's icon "-1"
means that number indicator on the badge will be decreased by one
- so there will be no badge on the icon */
localNotification.repeatInterval = NSDayCalendarUnit;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = -1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
