iPhone Title and Subtitle in Navigation Bar
- by Reuven
Hi there,
In my application, I'd like to have the navigation bar display a title and subtitle.
To that extent, I added the following code to my view controller:
// Replace titleView
CGRect headerTitleSubtitleFrame = CGRectMake(0, 0, 200, 44);
UIView* _headerTitleSubtitleView = [[[UILabel alloc] initWithFrame:headerTitleSubtitleFrame] autorelease];
_headerTitleSubtitleView.backgroundColor = [UIColor clearColor];
_headerTitleSubtitleView.autoresizesSubviews = YES;
CGRect titleFrame = CGRectMake(0, 2, 200, 24);
UILabel *titleView = [[[UILabel alloc] initWithFrame:titleFrame] autorelease];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20];
titleView.textAlignment = UITextAlignmentCenter;
titleView.textColor = [UIColor whiteColor];
titleView.shadowColor = [UIColor darkGrayColor];
titleView.shadowOffset = CGSizeMake(0, -1);
titleView.text = @"";
titleView.adjustsFontSizeToFitWidth = YES;
[_headerTitleSubtitleView addSubview:titleView];
CGRect subtitleFrame = CGRectMake(0, 24, 200, 44-24);
UILabel *subtitleView = [[[UILabel alloc] initWithFrame:subtitleFrame] autorelease];
subtitleView.backgroundColor = [UIColor clearColor];
subtitleView.font = [UIFont boldSystemFontOfSize:13];
subtitleView.textAlignment = UITextAlignmentCenter;
subtitleView.textColor = [UIColor whiteColor];
subtitleView.shadowColor = [UIColor darkGrayColor];
subtitleView.shadowOffset = CGSizeMake(0, -1);
subtitleView.text = @"";
subtitleView.adjustsFontSizeToFitWidth = YES;
[_headerTitleSubtitleView addSubview:subtitleView];
_headerTitleSubtitleView.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleBottomMargin);
self.navigationItem.titleView = _headerTitleSubtitleView;
And also implemented a method:
-(void) setHeaderTitle:(NSString*)headerTitle andSubtitle:(NSString*)headerSubtitle {
assert(self.navigationItem.titleView != nil);
UIView* headerTitleSubtitleView = self.navigationItem.titleView;
UILabel* titleView = [headerTitleSubtitleView.subviews objectAtIndex:0];
UILabel* subtitleView = [headerTitleSubtitleView.subviews objectAtIndex:1];
assert((titleView != nil) && (subtitleView != nil) && ([titleView isKindOfClass:[UILabel class]]) && ([subtitleView isKindOfClass:[UILabel class]]));
titleView.text = headerTitle;
subtitleView.text = headerSubtitle;
}
Things work beautifully, thanks.
Except that when rotating the iPhone to Landscape, the title+subtitle don't downsize in an automatic manner like the default title of the navigation item.
Any pointers?
Thanks!
