Question

I want to be able to display the system timezone as separate plain text in my app when it launches:

- (void)viewDidLoad {
    [super viewDidLoad];

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
    [dateFormatter setDateStyle:NSDateFormatterShortStyle];
    NSString* date = [dateFormatter stringFromDate:[NSDate date]];
    lblDate.text = date;

NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
[dateFormatter setTimeZone:gmt];
NSString* zone = [gmt:[NSTimeZone defaultTimeZone]];
txtTZ.text = zone;`

My app can display the date correctly but crashes upon the timezone. Any suggestions?

Answer 1

Try replacing this:

NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
[dateFormatter setTimeZone:gmt];
NSString* zone = [gmt:[NSTimeZone defaultTimeZone]];
txtTZ.text = zone;

With this:

NSString *zone = [[NSTimeZone systemTimeZone] abbreviation];
txtTZ.text = zone;
