Local Notification in iOS 10 for Objective-C and Swift 3

The way you use to work with Local Notification in iOS 9 and below is completely different in iOS 10.

Below screen grab from Apple release notes depicts this.

You can refer apple reference document https://developer.apple.com/reference/usernotifications for UserNotification.

Below is code for local notification :

Objective-C :

1. In App-delegate.h file use @import UserNotifications;

2. App-delegate should conform to UNUserNotificationCenterDelegate protocol

3. In didFinishLaunchingOptions use below code :

 UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];

    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)

                          completionHandler:^(BOOL granted, NSError * _Nullable error) {

                              if (!error) {

                                  NSLog(@"request authorization succeeded!");

                                  [self showAlert];

                              }

                          }];

-(void)showAlert {

    UIAlertController *objAlertController = [UIAlertController alertControllerWithTitle:@"Alert" message:@"show an alert!" preferredStyle:UIAlertControllerStyleAlert];

    

    UIAlertAction *cancelAction = [UIAlertAction

                                   actionWithTitle:@"OK"

                                   style:UIAlertActionStyleCancel

                                   handler:^(UIAlertAction *action) {

                                       NSLog(@"Ok clicked!");

                                   }];

    [objAlertController addAction:cancelAction];

    

    

    [[[[[UIApplication sharedApplication] windows] objectAtIndex:0] rootViewController] presentViewController:objAlertController animated:YES completion:^{

        

    }];

    

}

4. Now create a button in any view controller and in IBAction use below code :

 UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];

    objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@“Notification!” arguments:nil];

    objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@“This is local notification message!“

                                                         arguments:nil];

    objNotificationContent.sound = [UNNotificationSound defaultSound];

    

    /// 4. update application icon badge number

    objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);

    

    // Deliver the notification in five seconds.

    UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger

                                                  triggerWithTimeInterval:10.f repeats:NO];       

    

    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@“ten”

                                                                          content:objNotificationContent trigger:trigger];

    /// 3. schedule localNotification

    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];

    [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {

        if (!error) {

            NSLog(@“Local Notification succeeded“);

        }

else {

    NSLog(@“Local Notification failed“);

}

    }];

Swift 3:

1. In App-delegate.h file use import UserNotifications

2. App-delegate should conform to UNUserNotificationCenterDelegate protocol

3. In didFinishLaunchingWithOptions use below code 

 // Override point for customization after application launch.

        let center = UNUserNotificationCenter.current()

        center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in

            // Enable or disable features based on authorization.

            if((error == nil)) {

                print(“Request authorization failed!")

            }

            else {

                print(“Request authorization succeeded!")

                self.showAlert()

            }

        }

func showAlert() {

        let objAlert = UIAlertController(title: "Alert", message: "Request authorization succeeded", preferredStyle: UIAlertControllerStyle.alert)

        

        objAlert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))

        //self.presentViewController(objAlert, animated: true, completion: nil)

        

        UIApplication.shared().keyWindow?.rootViewController?.present(objAlert, animated: true, completion: nil)

    }

4. Now create a button in any view controller and in IBAction use below code :

let content = UNMutableNotificationContent()

        content.title = NSString.localizedUserNotificationString(forKey: "Hello!", arguments: nil)

        content.body = NSString.localizedUserNotificationString(forKey: "Hello_message_body", arguments: nil)

        content.sound = UNNotificationSound.default()

        content.categoryIdentifier = "notify-test"

        

        let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)

        let request = UNNotificationRequest.init(identifier: "notify-test", content: content, trigger: trigger)

        

        let center = UNUserNotificationCenter.current()

        center.add(request)

Regex for checking 10 digit mobile number

if([self validatePhone:searchBar.text])

   NSlog(“Valid mobile number”);   

else

   NSlog(“Invalid mobile number”);

- (BOOL)validatePhone:(NSString *)phoneNumber

{

   // NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$";

    NSString * phoneRegex = @"^(\\+?)(\\d{10})$”;

    NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex];

    

    return [phoneTest evaluateWithObject:phoneNumber];

}

-(BOOL) validateEmail:(NSString *)email

{

    NSString *emailRegex = @"^[^-._]+([A-Z0-9a-z]|([-._][^-._]))+[^-._]?@[A-Za-z0-9-]+\\.[A-Za-z]{2,4}$";

    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];

    return [emailTest evaluateWithObject:email];

}

Add INR ahead of price value Eg. INR. 1,000

 _lblPriceValue.text = [_ModelController.price changePriceformatAndAddUnit];

- (NSString *)changePriceformatAndAddUnit {

    return [NSString stringWithFormat:@“INR. %@", [self changePriceformat]];

}

- (NSString *)changePriceformat {

    int count = 0;

    long long int a = self.longLongValue;

    while (a != 0) {

        count++;

        a /= 10;

    }

    

    NSMutableString *string = [NSMutableString stringWithString:self];

    NSMutableString *newstring = [NSMutableString string];

    while (count > 3) {

        count -= 3;

        NSRange rang = NSMakeRange(string.length - 3, 3);

        NSString *str = [string substringWithRange:rang];

        [newstring insertString:str atIndex:0];

        [newstring insertString:@"," atIndex:0];

        [string deleteCharactersInRange:rang];

    }

    [newstring insertString:string atIndex:0];

    

    return newstring;

}

Create local notification in iOS

LocalNotification.h file :

#import <Foundation/Foundation.h>

@interface LocalNotification : NSObject

+ (LocalNotification*)standardLocalNotification;

- (void)scheduleAlert:(NSString*)alertBody;

- (void)scheduleAlert:(NSString*)alertBody fireDate:(NSDate*)fireDate;

@end

LocalNotification.m file :

#import <UIKit/UIKit.h>

#import "LocalNotification.h"

static LocalNotification*   localNotification = nil;

@interface LocalNotification(){

    UIApplication* application;

}

@end

@implementation LocalNotification

- (void)dealloc{

    [super dealloc];

}

- (instancetype)init{

    self = [super init];

    if (self) {

Status bar overlap view in iOS 7 and above

- (void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        CGRect screen = [[UIScreen mainScreen] bounds];
        if (self.navigationController) {
            CGRect frame = self.navigationController.view.frame;
            frame.origin.y = 20;
            frame.size.height = screen.size.height - 20;
            self.navigationController.view.frame = frame;
        } else {
            if ([self respondsToSelector: @selector(containerView)]) {
                UIView *containerView = (UIView *)[self performSelector: @selector(containerView)];

                CGRect frame = containerView.frame;
                frame.origin.y = 20;
                frame.size.height = screen.size.height - 20;
                containerView.frame = frame;
            } else {
                CGRect frame = self.view.frame;
                frame.origin.y = 20;
                frame.size.height = screen.size.height - 20;
                self.view.frame = frame;
            }
        }
    }
}

Add this to make your status bar white just right after the  [self.window makeKeyAndVisible];  in App delegate file
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
