Who is Chromebook Pixel for?

The rumored Chromebook Pixel is announced with a pricey $1299 price tag.

Chromebook with a 12.85 Retina-quality Touchscreen?

Why would someone buy the Web-only machine when he could buy the Macbook Air or Macbook Pro at a lesser price?

 

The Chromebook Pixel is not for you

Google just announced its first premium Chromebook, the Chromebook Pixel. It’s gorgeous. Unfortunately, it’s so expensive that I can’t think of a single person who should get one.

It’s kind of weird to see iPhone outperforms Android in the Android dominated world.

However, iPhone 5 was already the best-selling smartphone in the US.

How to add geofencing Reminders to iOS programically

Reference : Calendar and Reminders Programming Guide from iOS Developer Library

Apple provides a way to add a Reminder through EventKit from iOS 6.

1. Before start coding, you should add the EventKit Framework to the target first.

eventkit

2. Check whether iOS is over 6. (Reminder API is available above iOS6)

if ([[EKEventStore class] instancesRespondToSelector:@selector(requestAccessToEntityType:completion:)] == NO) {
    return nil;
}

3. Init EKEventStore and request access.

EKEventStore *store = [[EKEventStore alloc] init];
 
[store requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
    // handle access here
    if (granted) {
        // Create Reminder... [1]
    }
    [store release];
}];

4. If access is granted, Create reminder and add location alarm. (Code should be inside [1])

EKReminder *reminder = [EKReminder reminderWithEventStore:store];
reminder.title = @"Geofence Reminder";
reminder.calendar = [store defaultCalendarForNewReminders]; // Use default calendar for new reminders
 
EKAlarm *alarm = [[EKAlarm alloc] init];
 
EKStructuredLocation *location = [EKStructuredLocation locationWithTitle:@"Location title"];
CLLocation *clLocation = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];
location.geoLocation = clLocation;
[clLocation release];
 
[alarm setStructuredLocation:location];
alarm.proximity = EKAlarmProximityEnter; // Remind when enter or leave
[reminder addAlarm:alarm];
[alarm release];
 
// Save reminder
NSError *error;
[store saveReminder:reminder commit:YES error:&error];
if (error != nil) {
    NSLog(@"reminder error:%@",[error description]);
}

Done!
