Question

I have this string —-> Sun, 16 Dec 2012 15:30:22 +0000

I want to convert it to NSDate. I have tried the below code but it is giving me null

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

[df setDateFormat:@"yyyy-MM-dd hh:mm:ss a"];

NSDate *date = [[NSDate alloc] init];

date = [df dateFromString: @"Sun, 16 Dec 2012 15:30:22 +0000"];

NSLog(@"date: %@", date);

I am not getting the issue ?

Any guidance plz

Answer 1

The dateFormat of the formatter needs to match the format of the string you are providing it with.

Therefore something like this should work

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"EEE, dd MMM yyyy HH:mm:ss ZZZ";

NSLog(@"%@", [formatter dateFromString:@"Fri, 18 Jan 2013 15:30:22 +0000"]);

To look up what the specifiers actually mean check Unicode Technical Standard #35
