PagingView Function


                                              
                                                func dequeueReusableCellWithReuseIdentifier(identifier: String) -> PagingView.PagingViewCell

Used by the delegate to acquire an already allocated cell, in lieu of allocating a new one.


                                              
                                                func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

If a nib is registered, it must contain exactly 1 top level object which is a PagingViewCell.


                                              
                                                func registerClass<T : PagingView.PagingViewCell>(viewClass: T.Type, forCellWithReuseIdentifier identifier: String)

If a class is registered, it will be instantiated via init(frame: CGRect).


                                              
                                                func reloadData()

Requery the dataSource and delegate as necessary.


                                              
                                                func invalidateLayout()

Relayout as necessary.


                                              
                                                func numberOfSections() -> Int

func numberOfItemsInSection(section: Int) -> Int

Information about the current state of the PagingView.


                                              
                                                func scrollToPosition(position: PagingView.PagingView.Position, indexPath: IndexPath? = default, animated: Bool = default)

To scroll at Position.
Cell configure is performed at IndexPath.


                                              
                                                func configureAtPosition(position: PagingView.PagingView.Position, toIndexPath: IndexPath? = default)

IndexPath of cell in the center if indexPath is nil.

PagingViewDataSource Function


                                              
                                                func pagingView(pagingView: PagingView.PagingView, numberOfItemsInSection section: Int) -> Int

Paging count number of paging item in section.


                                              
                                                func pagingView(pagingView: PagingView.PagingView, cellForItemAtIndexPath indexPath: IndexPath) -> PagingView.PagingViewCell

Implementers should always try to reuse cells by setting each cell’s reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithReuseIdentifier:.


                                              
                                                optional func numberOfSectionsInPagingView(pagingView: PagingView.PagingView) -> Int

Paging count number of paging item section in PagingView.
Default return value is 1.


                                              
                                                optional func indexPathOfStartingInPagingView(pagingView: PagingView.PagingView) -> IndexPath?

IndexPath when pagingView:cellForItemAtIndexPath: is first called
Default return value is 0 - 0 of IndexPath instance.

PagingViewDelegate Function


                                              
                                                optional func pagingView(pagingView: PagingView.PagingView, willDisplayCell cell: PagingView.PagingViewCell, forItemAtIndexPath indexPath: IndexPath)

optional func pagingView(pagingView: PagingView.PagingView, didEndDisplayingCell cell: PagingView.PagingViewCell, forItemAtIndexPath indexPath: IndexPath)

Called at the display and end-display of.

PagingViewCell Function


                                              
                                                func prepareForReuse()

if the cell is reusable (has a reuse identifier), this is called just before the cell is returned from the paging view method dequeueReusableCellWithReuseIdentifier:.
