本地通知不在iphone中触发

这可能是一个重复的问题，但请帮助我。我使用下面的代码来发射本地通知，但它并未发射。我使用了一个拾取器来设置发射本地请帮助我..本地通知不在iphone中触发

[self.actionSheet dismissWithClickedButtonIndex:0 animated:YES]; 
if (nil != self.data) { 
    //send data picker message 
    [self.target performSelector:self.action withObject:[NSNumber numberWithInt:self.selectedIndex]]; 
} 
else {    
    //NSDate *date = [NSDate date]; 
    //NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init]; 
    //[dateFormat setDateFormat:@"HH:mm:ss zzz"]; 
    //NSString *dateString = [dateFormat stringFromDate:date]; 

    //send date picker message 
    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar]; 



    // Get the current date 
    NSDate *pickerDate = [self.datePickerView date]; 



    //NSLog(@"date ==%@",pickerdate); 
    //Break the date up into components 
    NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) 
                  fromDate:pickerDate]; 
    NSDateComponents *timeComponents = [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) 
                 fromDate:pickerDate]; 



    // Set up the fire time 
    NSDateComponents *dateComps = [[NSDateComponents alloc] init]; 
    [dateComps setDay:[dateComponents day]]; 
    [dateComps setMonth:[dateComponents month]]; 
    [dateComps setYear:[dateComponents year]]; 
    [dateComps setHour:[timeComponents hour]]; 
    //NSLog(@"day%@",[dateComponents day]); 
    // Notification will fire in one minute 
    [dateComps setMinute:[timeComponents minute]]; 
    [dateComps setSecond:[timeComponents second]]; 
    NSDate *itemDate = [calendar dateFromComponents:dateComps]; 
    [dateComps release]; 




    UILocalNotification *localNotif = [[UILocalNotification alloc] init]; 
    if (localNotif == nil) 
     return; 
    localNotif.fireDate = itemDate; 
    NSLog(@"%@what is this",itemDate); 

    localNotif.timeZone = [NSTimeZone defaultTimeZone]; 



    //Notification details 
    localNotif.alertBody = @"Tip of the day"; 

    //Set the action button 
    localNotif.alertAction = @"View"; 



    localNotif.soundName = UILocalNotificationDefaultSoundName; 
    localNotif.repeatInterval = NSDayCalendarUnit; 



    localNotif.applicationIconBadgeNumber = 1; 



    // Specify custom data for the notification 
    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"]; 
    localNotif.userInfo = infoDict; 

// Schedule the notification 

    [localNotif release]; 
}

当你从这个问题复制粘贴代码http://stackoverflow.com/questions/6785989/local-notification-not-firing-in-iphone。您错过了[[[UIApplication sharedApplication] scheduleLocalNotification：localNotif];' –

如果您的应用程序处于前台，则通知也不会出现 –

@ xs2bush对不起，我发布我的答案之前没有看到您的评论发布。 – MiguelB

调度local notification的代码在哪里？

你有你释放你的UILocalNotification对象之前拨打这通电话的地方：

- (void)scheduleLocalNotification:(UILocalNotification *)notification

像这样，

[[UIApplication sharedApplication] scheduleLocalNotification: localNotif];

调用此方法，你notification被复制后，才，因此其可以安全地释放通知对象。
