iOS - Converting time and date to user time zone

Question

I am sending some requests on a webserver that replies me time and date like this:

\"at 18:58 of 05/08/2012\"

I can figure out how to get t

Answer 1

You should do it the following way:

1) First, create an NSDateFormatter to get the NSDate sent from the server:

NSDateFormatter *serverFormatter = [[NSDateFormatter alloc] init];
[serverFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"GMT"]];
[serverFormatter setDateFormat:@"'at 'HH:mm' of 'dd/MM/yyyy"];

From Apple docs: note with the Unicode format string format, you should enclose literal text in the format string between apostrophes ('').

2) Convert the string (consider it is defined as theString) to a NSDate:

NSDate *theDate = [serverFormatter dateFromString:theString];

3) Create an NSDateFormatter to convert theDate to the user:

NSDateFormatter *userFormatter = [[NSDateFormatter alloc] init];
[userFormatter setDateFormat:@"HH:mm dd/MM/yyyy"];
[userFormatter setTimeZone:[NSTimeZone localTimeZone]];

3) Get the string from the userFormatter:

NSString *dateConverted = [userFormatter stringFromDate:theDate];
