Provided Methods

unsafe fn pageControlProgress_initialProgressForPage( &self, progress: &UIPageControlProgress, page: NSInteger, ) -> c_float

where Self: Sized + Message,

Returns the initial progress (between 0…1) for the specified page. By default, currentProgress is set to 0 when the page changes.

unsafe fn pageControlProgressVisibilityDidChange( &self, progress: &UIPageControlProgress, )

where Self: Sized + Message,

Called when the page control progress visibility has changed, which could occur when the page control is being interacted with. The page control progress becomes hidden when the user begins to interact with the page control (when it begins continuous interaction), and is visible again when the user stops interacting with the control. Observe the page control progress visibility to pause or resume the paging content.

Example:

 - (void)pageControlProgressVisibilityDidChange:(UIPageControlProgress *)progress {
     BOOL isProgressVisible = progress.isProgressVisible;
     if (isProgressVisible) {
         [self _resumeContentFromInteractionChanges];
     } else {
         [self _pauseContentFromInteractionChanges];
     }
 }
