For example, the Code for sliding switching between news channels and news channels

Effect:

CollectionView Data Source Method

-(UICollectionViewCell *) collectionView :( UICollectionView *) collectionView cellForItemAtIndexPath :( NSIndexPath *) indexPath

{

NewsCell * cell = [collectionViewdequeueReusableCellWithReuseIdentifier: @ "news" forIndexPath: indexPath];

NSString * urlString = self. arrayList [indexPath. item];

If (! [Self. childViewControllerscontainsObject: cell. newsVc]) {

[SelfaddChildViewController :( UIViewController *) cell. newsVc];

}

Cell. urlStr = urlString;

Return cell;

}

Cell customization is as follows:

-(Void) setUrlStr :( NSString *) urlStr

{

_ UrlStr = urlStr;

Self. newsVc. urlStr = urlStr;

}

-(Void) awakeFromNib

{

UIStoryboard * sb = [UIStoryboardstoryboardWithName: @ "news" bundle: nil];

Self. newsVc = sb. instantiateInitialViewController;

// Set the view frame. Otherwise, the size of the view frame will not be adjusted!

Self. newsVc. view. frame = self. bounds;

// Add the vc View to the cell

[SelfaddSubview: self. newsVc. view];

}
