Improve this question
Hello this is the iOS project I'm working on .
I'm just a beginner at programming iOS apps.
I just need help so that I can improve ><
Here's my app so far.
So my job is under the reminder that shows the box " Daily Vibes".
I need to include 100 messages randomly.
I've heard of arc random function. I just need some examples on how to do use it.
Here's my code :
AppDelegate.m
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Daily Vibes"
message:notification.alertBody
delegate:self cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
AddtoDoViewController.m
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
I would like some assistance please.
Thank you.
Expectation :
With the box
Daily Vibes
-Attached 100 random messages-
Example of the affirmation :
NSarray *100affirmations = #[#"Every day in every way I am getting happier and happier.",
#"I am thankful to everybody who has touched my life and made it worth living. ",
#"Happiness is contagious. My happiness makes all these people happy, thus making it one big happy world.",
#"My happy disposition attracts happiness into my life and I only interact with happy people and have only happy experiences.",
#"I spread happiness to others and absorb happiness from others. I enjoy every moment of the day.",
#"Be happy is my motto and happiness is not a destination. It’s my way of life.",
#"I am living my life, feeling motivated and excited about the greatness I am creating, on a daily basis.",
#"I am going to make the best out of my life. I will appreciate all opportunities which are given to me and follow my way.",

Put your messages in an NSMutableArray and the following method will be good enough for your purposes I think:
+ (void) randomOrderedMutableArray:(NSMutableArray *) array
{
int count = [array count];
for (int i = 0; i < count; ++i)
{
int nElements = count - i;
int n = (arc4random() % nElements) + i;
[array exchangeObjectAtIndex:i withObjectAtIndex:n];
}
}
