How can I display the current time on a shortcut?

Question

How can I display the current time on the iphone shortcut?

Answer 1

Ok Here is what you need.

Place the IBOutlet shortcut in your .h file of your view controller and connect to the .xib file.

Now just put the following code in your .m controller file.

- (void)viewDidLoad { [super viewDidLoad]; // your label text is set to current time lblTime.text=[[NSDate date] description]; // timer is set & will be triggered each second [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(showTime) userInfo:nil repeats:YES]; } // following method will be called frequently. -(void)showTime{ lblTime.text=[[NSDate date] description]; } 

Answer 2

Objective-c

 NSDate *currDate = [NSDate date]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init]; [dateFormatter setDateFormat:@"dd.MM.YY HH:mm:ss"]; NSString *dateString = [dateFormatter stringFromDate:currDate]; yourLabel.text=dateString 

Swift 3.0

 var currDate = Date() var dateFormatter = DateFormatter() dateFormatter.dateFormat = "dd.MM.YY HH:mm:ss" var dateString = dateFormatter.string(fromDate: currDate) yourLabel.text! = dateString 

Answer 3

Use NSTimer to run regular calls to a method that updates the label.

Answer 4

If you need to format the date before showing it, use the NSDateFormatter class.
