Answer 1

You will have to use NSDate ,

First Construct an NSDate object with current time

NSDate *today = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm:ss"];
NSString *currentTime = [dateFormatter stringFromDate:today];
[dateFormatter setDateFormat:@"dd.MM.yyyy"];
NSString *currentDate = [dateFormatter stringFromDate:today];

Now currentDate is the string object, you can display it with UILabel on screen,

likewise you could create date and get the string object for Next day …..
