How to print the time with AM/PM format in iPhone?

Question

I want to print the time from date picker but with the AM/PM. I can print the time, but it never prints the AM/PM. How can I do this?

Answer 1

Use below lines of code

    NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
    [dateFormatter setDateFormat:@"hh:mm a"];   
    NSString *str_date = [dateFormatter stringFromDate:[NSDate date]];
    NSLog(@"str_date:%@",str_date);

Answer 2

You could use this document for more information NSDateFormatter Class Reference .An example could be:

NSDate* date = [NSDate date];
NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"MM/dd/yyyy"];

[formatter setTimeStyle:NSDateFormatterFullStyle];
NSLog(@"date=%@",[dateFormatter stringFromDate:date]);

Answer 3

You can set your DateFormatter amSymbol and pmSymbol as follow:

Xcode 8.3 • Swift 3.1

let formatter = DateFormatter()
formatter.dateFormat = "h:mm a 'on' MMMM dd, yyyy"
formatter.amSymbol = "AM"
formatter.pmSymbol = "PM"

let dateString = formatter.string(from: Date())
print(dateString)   // "4:44 PM on June 23, 2016\n"

Edit: Objective C Code

NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.timeZone = [NSTimeZone systemTimeZone];
df.AMSymbol = @"AM";
df.PMSymbol = @"PM";
df.dateFormat = "h:mm a 'on' MMMM dd, yyyy"
NSString *stringDate = [df stringFromDate:dateFromString];

Date to String

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@“dd-MMM”];
cell.dateLabel.text = [formatter stringFromDate:item.pubDate]

Date Format Symbols The table from the unicode date formatting page should be enough for you to build your own desired date format string…

Pattern Result (in a particular locale)
yyyy.MM.dd G ‘at’ HH:mm:ss zzz  1996.07.10 AD at 15:08:56 PDT
EEE, MMM d, ‘’yy    Wed, July 10, ‘96
h:mm a  12:08 PM
hh ‘o’‘clock’ a, zzzz   12 o’clock PM, Pacific Daylight Time
K:mm a, z   0:00 PM, PST
yyyyy.MMMM.dd GGG hh:mm aaa 01996.July.10 AD 12:08 PM

Answer 5

for printing AM/ PM the parameter a/aa/aaa all will work.

NSDateFormatter *myDateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[myDateFormatter setDateFormat:@"hh:mm aaa"]; //a,aa or aa all will work.
[myDateFormatter setDateFormat:@"hh:mm aa"];
NSString *myDate = [myDateFormatter stringFromDate:[NSDate date]];
NSLog(@"myDate is :%@",myDate);

Answer 6

You can use in swift 5

    var strDate1:String = "2019-12-19 05:42:04";
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    let dateObj = dateFormatter.date(from: strDate1)
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss a"
    let strigDate =  dateFormatter.string(from: dateObj!)

Output: 2019-12-19 05:42:04 AM
