Question

我已经以编程方式添加了本地通知，如下所示：

UILocalNotification *eventLocalNotification=[[UILocalNotification alloc]init];
eventLocalNotification.fireDate=myDate;
eventLocalNotification.timeZone=[NSTimeZone defaultTimeZone];
eventLocalNotification.alertBody=@"My notification";
eventLocalNotification.soundName=UILocalNotificationDefaultSoundName;

我可以更改firingDate，timeZone，alertBody或任何其他属性吗？

Answer 1

经过互联网搜索后，我得到了一个我们不能edit添加UILocal通知的东西。但确定我找到了另一种方式。

获取设备的所有本地通知。
搜索相应的本地通知
取消该通知
创建新的

以下是添加通知的方法。

-(void)setLocalNotification
{
    UILocalNotification *eventLocalNotification =   [[UILocalNotification alloc]init];

    eventLocalNotification.fireDate     =   //set firing Date of NSDate type
    eventLocalNotification.timeZone     =   [NSTimeZone defaultTimeZone];
    eventLocalNotification.alertBody    =   [NSString stringWithFormat:@"An event has arrived\n Event Name: %@",notificationName.Text];
    eventLocalNotification.soundName    =   UILocalNotificationDefaultSoundName;

    if ([repeat isEqualToString:@"Once"]){

        eventLocalNotification.repeatInterval   =   0;

    }else if ([repeat isEqualToString:@"Daily"]){

        eventLocalNotification.repeatInterval   =   NSDayCalendarUnit;

    }else if ([repeat isEqualToString:@"Weekly"]){

        eventLocalNotification.repeatInterval   =   NSWeekCalendarUnit;

    }else if ([repeat isEqualToString:@"Monthly"]){

        eventLocalNotification.repeatInterval   =   NSMonthCalendarUnit;

    }else if ([repeat isEqualToString:@"Yearly"]){

        eventLocalNotification.repeatInterval   =   NSYearCalendarUnit;
    }

    NSDictionary *info  =   [NSDictionary dictionaryWithObject:[NSString stringWithFormat:@"%@",notificationName.text] forKey:@"name"];
    eventLocalNotification.userInfo =   info;
    NSLog(@"notification userInfo gets name : %@",[info objectForKey:@"name"]);
    [[UIApplication sharedApplication] scheduleLocalNotification:eventLocalNotification];
    NSLog(@"Notification created");
}

以下是取消通知的功能

-(void)cancelLocalNotification
{
    UILocalNotification * notificationToCancel=nil;
    for(UILocalNotification * aNotif in [[UIApplication sharedApplication] scheduledLocalNotifications])
    {
        NSLog(@"%@",[aNotif.userInfo objectForKey:@"name"]);
        if([[aNotif.userInfo objectForKey:@"name"] isEqualToString:notificationName ])
        {
            notificationToCancel    =   aNotif;
            [[UIApplication sharedApplication] cancelLocalNotification:notificationToCancel];
            NSLog(@"Notification Cancelled");
            break;
        }
    }

}

希望你能从中受益。最好的运气

要设置日期和时间，您必须使用NSDateComponents并实例化两次NSDate。一个用于当前日期，另一个用于您理想的日期。然后将理想的NSDate实例设置为UILocalNotification对象的fireDate。

eventLocalNotification.fireDate = desiredDate;

对于时区，请按照您的方式保持默认值。

eventLocalNotification.timeZone = [NSTimeZone defaultTimeZone];

警报正文可以是任何东西，只需记下你的背景。

eventLocalNotification.alertBody = @"DESIRED CONTEXT";
