Question

I have an NSString like this: @"3/15/2012 9:15 PM" and I would like to convert it to NSDate, I have done like this:

NSString *str =@"3/15/2012 9:15 PM";
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:@"mm/dd/yyyy HH:mm"];
NSDate *date = [formatter dateFromString:];

NSLog(@"%@", date);  // date = null

Can you help me please, thanks.

Answer 1

Use the following solution

NSString *str = @"3/15/2012 9:15 PM";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"MM/dd/yyyy HH:mm a";

NSDate *date = [formatter dateFromString:str];

NSLog(@"%@", date);

Edit:
Sorry, the format should be as follows:

formatter.dateFormat = @"MM/dd/yyyy hh:mm a";

And the time shown will be GMT time. So if you add/subtract the timezone, it would be 9:15 PM.

Edit: #2

Use as below. You would get exact time too.

NSString *str = @"3/15/2012 9:15 PM";

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"MM/dd/yyyy hh:mm a";

NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];

formatter.timeZone = gmt;

NSDate *date = [formatter dateFromString:str];

NSLog(@"%@",date);
