Ive been racking my brains with no luck. Could someone please tell me how i would convert this string: "2011-01-13T17:00:00+11:00" into a NSDate? The unicode date format doc is here Also, for your situation, you could try this: // original string NSString *str = [NSString stringWithFormat:@"2011-01-13T17:00:00+11:00"]; // convert to date NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; // ignore +11 and use timezone name instead of seconds from gmt [dateFormat setDateFormat:@"YYYY-MM-dd'T'HH:mm:ss'+11:00'"]; [dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"Australia

I know there is this one: sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: But since the CGSize always has the same height and doesn't adjust to any shrinked text or whatsoever, the CGSize is not telling how heigh the text is.

Just to be complete: If you are absolutely sure of the format of your output you can use the array methods: NSString *inputString; // this is in the form "xxxx(yyyy)" NSCharacterSet *delimiters = [NSCharacterSet characterSetWithCharactersInString:@"()"]; NSArray *splitString = [inputString componentsSeparatedByCharactersInSet
