Local & Post Notification

Local & Post Notification

1) First Set Your Storyboard Like This :

2) Write Coding Which Is Given Below :

*ToDoListViewController (Set Notification) :

ToDoListViewController.h :

#import <UIKit/UIKit.h>

@interface ToDoListViewController : UITableViewController

@end

ToDoListViewController.m :

#import "ToDoListViewController.h"

@interface ToDoListViewController ()

- (void)reloadTable;

@end

@implementation ToDoListViewController

- (id)initWithStyle:(UITableViewStyle)style

{

    self = [super initWithStyle:style];

    if (self) {

        // Custom initialization

    }

    return self;

}

- (void)viewDidLoad

{

    [super viewDidLoad];

    [[NSNotificationCenter defaultCenter] addObserver:self

                                             selector:@selector(reloadTable)

                                                 name:@"reloadData"

                                               object:nil];

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

{

    // Return the number of sections.

    return 1;

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    // Return the number of rows in the section.

    return [[[UIApplication sharedApplication] scheduledLocalNotifications] count];

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    

    // Get list of local notifications

    NSArray *localNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications];

    UILocalNotification *localNotification = [localNotifications objectAtIndex:indexPath.row];

    

    // Display notification info

    [cell.textLabel setText:localNotification.alertBody];

    [cell.detailTextLabel setText:[localNotification.fireDate description]];

    

    return cell;

}

- (void)reloadTable

{

    [self.tableView reloadData];

}

*AddToDoViewController (Show In tableView & Fire) :

AddToDoViewController.h :

#import <UIKit/UIKit.h>

@interface AddToDoViewController : UIViewController <UITextFieldDelegate>

- (IBAction)cancel:(id)sender;

- (IBAction)save:(id)sender;

@property (weak, nonatomic) IBOutlet UITextField *itemText;

@property (weak, nonatomic) IBOutlet UIDatePicker *datePicker;

@end

AddToDoViewController.m :

#import "AddToDoViewController.h"

@interface AddToDoViewController ()

@end

@implementation AddToDoViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

        // Custom initialization

    }

    return self;

}

- (void)viewDidLoad

{

    [super viewDidLoad];

// Do any additional setup after loading the view.

    

    self.itemText.delegate = self;

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (IBAction)cancel:(id)sender

{

    [self dismissViewControllerAnimated:YES completion:nil];

}

- (IBAction)save:(id)sender

{

    [self.itemText resignFirstResponder];

    

    // Get the current date

    NSDate *pickerDate = [self.datePicker date];

    

    // Schedule the notification

    UILocalNotification* localNotification = [[UILocalNotification alloc] init];

    localNotification.fireDate = pickerDate;

    localNotification.alertBody = self.itemText.text;

    localNotification.alertAction = @"Show me the item";

    localNotification.timeZone = [NSTimeZone defaultTimeZone];

    localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;

    

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

    

    // Request to reload table view data

    [[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];

    // Dismiss the view controller

    [self dismissViewControllerAnimated:YES completion:nil];

}

- (BOOL)textFieldShouldReturn:(UITextField *)textField

{

    [self.itemText resignFirstResponder];

    return NO;

}

@end
