NSDate dateFromString deprecated?

Question

I'm trying to use the NSDate dateFromString method but I'm getting an warning and it's crashing the app. The code looks like:

NSString *pickerDate = [NSString stringWithFormat:@"%@", timeSelector.date];
NSDate *defaultDate = [NSDate dateFromString:pickerDate];

The warning is:

'NSDate' may not respond to '+dateFromString'.

It appears that method is deprecated (in the midst of an upgrade from XCode 2 to 3.

What alternate method can I use to create a date from a string?

Answer 1

NSDateFormatter is the intended way for you to get an NSDate from an NSString.

The most basic usage is something like this:

NSString *dateString = @"3-Aug-10";

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
dateFormatter.dateFormat = @"d-MMM-yy";

NSDate *date = [dateFormatter dateFromString:dateString];

Answer 2

I had a same problem. I changed the dateFormat from @"YYYY/M/d H:m:s" to @"YYYY/MM/dd HH:mm:ss" as follows. Then it works on my iPhone 4. (Xcode 4.5 for iOS 6.)

NSDateFormatter *dateFormatter1;
NSString *dateStr1=@"";
NSDate *gantanDate1;

dateFormatter1 = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter1 setLocale:[NSLocale systemLocale]]; 
[dateFormatter1 setTimeZone:[NSTimeZone systemTimeZone]]; 
dateFormatter1.dateFormat=@"YYYY/MM/dd HH:mm:ss";
dateStr1=@"2012/1/1 00:00:00"];
//  in his case,   dateStr1=pickerDate;  
gantanDate1 = [dateFormatter1 dateFromString:dateStr1];
