Delegate Warning!

In order to intercept delegate messages, this class uses WZProtocolInterceptor. If you call self.richTextView.delegate, you will get the WZProtocolInterceptor object, not the original delegate that you set earlier with self.richTextView.delegate = ...! If you need to get the delegate that you set, call [self.richTextView textViewDelegate]. (This is caused by the richTextView needing its own delegate methods.)

Note

If text is set before the view is fully shown, the text may start scrolled to the bottom. Look here for solutions.

Custom Font Size Selection

Font size selection can be customized by implementing the following data source method

- (NSArray *)fontSizeSelectionForRichTextEditor:(RichTextEditor *)richTextEditor {
	// pass an array of NSNumbers
	return @[@5, @10, @20, @30];
}

Custom Font Family Selection

Font family selection can be customized by implementing the following data source method

- (NSArray *)fontFamilySelectionForRichTextEditor:(RichTextEditor *)richTextEditor {
    // pass an array of Strings
    // Can be taken from [UIFont familyNames]
    return @[@"Helvetica", @"Arial", @"Marion", @"Papyrus"];
}

Presentation Style

You can switch between popover, or modal (presenting font-picker, font-size-picker, color-picker dialogs) by implementing the following data source method

- (RichTextEditorToolbarPresentationStyle)presentarionStyleForRichTextEditor:(RichTextEditor *)richTextEditor {
  // RichTextEditorToolbarPresentationStyleModal Or RichTextEditorToolbarPresentationStylePopover
	return RichTextEditorToolbarPresentationStyleModal;
}

Modal Presentation Style

When presentarionStyleForRichTextEditor is a modal, modal-transition-style & modal-presentation-style can be configured

- (UIModalPresentationStyle)modalPresentationStyleForRichTextEditor:(RichTextEditor *)richTextEditor {
	return UIModalPresentationFormSheet;
