Listen to the Changes of Block Editing

 

ComPDFKit PDF SDK offers developers an API for programmatic change of editing status, which is easy to adjust related UI effects.

 

/**
 * Called when the editing changes.
 */
- (void)PDFViewEditingOperationDidChanged:(CPDFView *)pdfView;

/**
 * Called when the selected block or selected certain area changes.
 */
- (void)PDFViewEditingSelectStateDidChanged:(CPDFView *)pdfView;

/**
 * Called when the selected text block enters the text-editing status.
 */
- (void)PDFEditingViewShouldBeginEditing:(CPDFView *)pdfView textView:(UITextView *)textView;

/**
 * Called when the selected text block ends the text-editing status.
 */
- (void)PDFEditingViewShouldEndEditing:(CPDFView *)pdfView textView:(UITextView *)textView;

When selecting a text block or a certain area, you can use editStatus: of CPDFView to get the current text-editing status. The following is the introduction to each status.

- CEditingSelectStateEmpty Does not enter the text-editing status.

- CEditingSelectStateEditTextArea Selects a text block without entering the text-editing status.

- CEditingSelectStateEditNoneText Enters the text-editing status without selecting text.

- CEditingSelectStateEditSelectText Enters the text-editing status and selects text.
