How do I change NSTime format from hh:mm:ss to hh:mm a?

Question

I want to change the time format from string, I am having the values in hh:mm:ss in 24 hr format and I want to make it hh:mm:a in 12 hr format.

I have tried -

    NSDateFormatter *format = [[NSDateFormatter alloc] init];
    [format setDateFormat:@"hh:mm:ss"];

    NSDate *date123 = [format dateFromString:temp123];
    [format setDateFormat:@"hh:mm a"];
    NSString* newDateString = [format stringFromDate:date123];

please help me.

Answer 1

if your temp123 in 24 hour format, then use HH instead of hh

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"HH:mm:ss"];

NSDate *date123 = [format dateFromString:temp123];
[format setDateFormat:@"hh:mm a"];
[format setAMSymbol:@"am"];
[format setPMSymbol:@"pm"];
NSString* newDateString = [format stringFromDate:date123];
