Change a font from a popover for underling scrollview - ios

Question

I am using Xcode 4.5, targeting iOS5 and above.
I have a popover that allows a user to change the fonts of the underlying view.
When tapping on the font, the change does not occur, until after I close the popover and the underling view and reopen.
It is set up for delegation. And the receiving view does import the the FontsPopoverViewDelegate.
Any help toward a solution would be greatly appreciated.
The Delegate methods for fonts:
#protocol FontsPopoverViewDelegate <NSObject>
- (void)fontResize:(float)size forView:(int)type;
- (void)font:(int)fontID forView:(int)fView;
- (int)getFontForView:(int)fView;
- (float)getFontSizeForView:(int)fView;
#end
Methods implemented in underlying view:
- (void)fontResize:(float)size forView:(int)type {
fontSizes[type] = size;
[self invalidate];
}
- (void)font:(int)fontID forView:(int)fView {
fontIds[fView] = fontID;
[self invalidate];
}
- (int)getFontForView:(int)fView {
return fontIds[fView];
[self invalidate];
}
- (float)getFontSizeForView:(int)fView {
return fontSizes[fView];
[self invalidate]; // added to spark a reaction from the view
}
-(void) invalidate {
NSLog(#"Invalidate called");
[self saveTextChanges];
[self refreshBodyText];
[self refreshBackground];
[self refreshBodyText];
[self refreshDateFont];
[self refreshTitleFont];
}
Any help would be greatly appreciated.

Answer 1

I solved this by posting a notification from the font popover to the underlying view. In the underlying view, I added the call... [self viewWillAppear:YES];
Now, it is working perfectly.
I have a slider, within the Fonts popover, that changes the size and a notification and calling viewWillAppear within the notification works the same as the font change.
- (void)aFontChanged:(NSNotification *)notification
{
NSLog(#"aFontChanged notification?");
[self viewWillAppear:YES];
[self refreshBodyText];
[self refreshDateFont];
[self refreshTitleFont];
}
- (void)aFontSizeChanged:(NSNotification *)notification
{
NSLog(#"aFontSizeChanged notification?");
[self viewWillAppear:YES];
[self refreshBodyText];
[self refreshDateFont];
[self refreshTitleFont];
}
