我想使用objective c在ios应用程序中为本地通知设置不同的警报正文

Question

我正在从地址簿中获取联系人并通过为每个通知获取不同的联系人姓名来显示警报正文，但它不起作用。

这是我的警报正文 :---(@"Ask %@ How you doin, How you been?",name)

这是我的代码，

-(void)setNotificationlocal{

    //get random contacts from adress book
   NSUInteger randomIndex = arc4random() % [self.localContactArray count];
    NSLog(@"random index---%lu",(unsigned long)randomIndex);
    NSString *name;
    NSString *mobNumber;
    if ([[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"] isEqualToString:@"<null>"] || [[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"] isEqualToString:@""] || [[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"]isEqualToString:@"(null)"]||[[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"]  isKindOfClass:[NSNull class]]  || [[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"] == nil){

        name=[[NSString alloc]initWithFormat:@"%@",[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"fName"]];
        mobNumber=nil;
        mobNumber=[[NSString alloc]initWithString:[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"num"]];
    }else{

        name=[[NSString alloc]initWithFormat:@"%@ %@",[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"fName"],[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"]];
        mobNumber=nil;
        mobNumber=[[NSString alloc]initWithString:[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"num"]];
    }


    // New for iOS 8 - Register the notifications

    UILocalNotification *notification = [[UILocalNotification alloc] init];
    if (notification)
    {
            notification.timeZone = [NSTimeZone defaultTimeZone];
            if ( [statusString isEqualToString:@"daily"]) {

                notification.fireDate =[NSDate dateWithTimeIntervalSinceNow:86400];
               // notification.repeatInterval = NSCalendarUnitDay;
               NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
                [defaults setObject:@"daily" forKey:@"KEY_NAME"];
                [defaults synchronize];

            }else if ( [statusString isEqualToString:@"weekly"]) {

                notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:604800];
               // notification.repeatInterval = NSCalendarUnitWeekOfYear;
               NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
                [defaults setObject:@"weekly" forKey:@"KEY_NAME"];
                [defaults synchronize];

            }else if ( [statusString isEqualToString:@"fortnightly"]) {
                notification.fireDate =  [NSDate dateWithTimeIntervalSinceNow:1209600];

//                notification.userInfo = @{@"notification_identifier":@"After14Days"};
//                notification.fireDate = [[NSDate date] dateByAddingTimeInterval:(60*60*24*14)];
//                notification.repeatInterval = NSCalendarUnitDay;
               NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
                [defaults setObject:@"fortnightly" forKey:@"KEY_NAME"];
                [defaults synchronize];

            }else{
                notification.repeatInterval = 0;
            }

            notification.alertBody = [NSString stringWithFormat:@"Ask %@ How you doin, How you been?",name];
            notification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
            notification.soundName = UILocalNotificationDefaultSoundName;

        notification.alertAction = @"say yes";
        notification.timeZone = [NSTimeZone defaultTimeZone];
        notification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
       // [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(showSMS) name:@"showSMS" object:nil];

        // this will schedule the notification to fire at the fire date
        [[UIApplication sharedApplication] scheduleLocalNotification:notification];
    }
}

As this answer，你只需检查一下

if ([[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"] == nil)
{
    name=[[NSString alloc]initWithFormat:@"%@",[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"fName"]];
}
else
{
    name=[[NSString alloc]initWithFormat:@"%@ %@",[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"fName"],[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"lName"]];
}
    mobNumber=[[NSString alloc]initWithString:[[self.localContactArray objectAtIndex:randomIndex] objectForKey:@"num"]];
