NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"hh-mm"]; 
NSString *resultString = [dateFormatter stringFromDate: currentTime]; 

Answer 2

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"hh-mm"]; 
NSDate *currentDate = [NSDate date]; 
NSString *currentDateString = [dateFormatter stringFromDate:currentDate]; 

Answer 3

NSDate *currentDate =[NSDate date]; 
//Your formatter goes here. 
NSString *currentTime = [dateFormatter stringFromDate:currentDate]; 

Answer 4

NSDate alloc init creará una fecha con la hora actual. Luego, puede usar NSDateFormatter stringFromDate para formatear y presentar esa fecha.

Este:

NSDate *date = [[NSDate alloc] init]; 
NSLog(@"%@", date); 

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"hh-mm"]; 
NSString *dateString = [dateFormatter stringFromDate:date]; 

NSLog(@"%@", dateString);

Answer 5

NSDate *today = [[NSDate alloc] init]; 
NSLog(@"today is :%@", date); 

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"hh-mm:ss"]; 
NSString *timeString = [dateFormatter stringFromDate:today]; 

NSLog(@"%@", timeString);
