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!
Instead of this authoresizing mask
you should use
Make the
titleView
andsubtitleView
labels into properties of the view controller, so that you can access them from any method. Then, on rotation of the view controller, resize the labels:
