Question

I need to show a date in a certain format on screen, but I need to store the date as a string in another format. I think this means I have to convert it to a date and back to a string.

How do i do this ?

I have already figured out how to convert my string to a date, however build analyser gives me a warning.

I want to convert the string from dd MM yyyy to yyyy-MM-dd

He my code so far…

NSString *startDateString = btnStartDate.titleLabel.text;
NSDateFormatter *dateStartFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateStartFormatter setDateFormat:@"dd MM yyyy"];
NSDate *datStartDate = [[NSDate alloc] init];
datStartDate = [dateStartFormatter dateFromString:startDateString];

Answer 1

The analyzer warns you of a leak. First, you assign a new object to datStartDate, and then you store a new value with datStartDate = [dateStartFormatter dateFromString:startDateString]; without releasing the previous object first.

So instead of:

NSDate *datStartDate = [[NSDate alloc] init];
datStartDate = [dateStartFormatter dateFromString:startDateString];

You should just write:

NSDate *datStartDate = [dateStartFormatter dateFromString:startDateString];
