私は通知をスケジュールし、それが警告メッセージを表示する必要がある前に警告60分にそれを与える...UILocalNotificationスケジュールアラート
私は通知を追加するとすぐに私のアプリのデリゲートのメソッドが呼び出された:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
アラートとしてバックグラウンドに表示されることがわかりますか?私はオーバーライドしたり、それが60分間隔でスケジュール警告を与えられたことを確認するために使用する必要がある任意の他のデリゲートメソッドが...あり
- (void)scheduleNotificationWithItem:(NSDate *)item interval:(int)minutesBefore
{
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
//NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *currentDateComponents = [calendar components:(NSWeekdayCalendarUnit |
NSYearCalendarUnit | NSMonthCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSWeekCalendarUnit | NSMinuteCalendarUnit) fromDate:item];
NSLog(@"- current components year = %i , month = %i , week = % i, weekday = %i", [currentDateComponents year], [currentDateComponents month], [currentDateComponents week], [currentDateComponents weekday]);
NSLog(@"[currentDateComponents minute]: %i", [currentDateComponents minute]);
NSLog(@"[currentDateComponents hour]: %i", [currentDateComponents hour]);
NSLog(@"[currentDateComponents day]: %i", [currentDateComponents day]);
NSLog(@"[currentDateComponents week]: %i", [currentDateComponents week]);
NSLog(@"[currentDateComponents month]: %i", [currentDateComponents month]);
NSLog(@"[currentDateComponents year]: %i", [currentDateComponents year]);
[dateComps setDay: [currentDateComponents day]];
[dateComps setMonth:[currentDateComponents month]];
[dateComps setYear:[currentDateComponents year]];
[dateComps setHour:[currentDateComponents hour]];
[dateComps setMinute:[currentDateComponents minute]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = [itemDate addTimeInterval:-(minutesBefore*60)];
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = [NSString stringWithFormat:@"%@\n%@",
streetAddress,
stringOfWhenAuctionIsOn];
localNotif.alertAction = NSLocalizedString(@"View Details", nil);
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:streetAddress
forKey:idOfStreetAlert];
localNotif.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
ちょうど不思議なことに、なぜ間隔を負の値に設定していますか?\ –
