How to set UICollectionView inside UIView - ios

Question

I am trying to add UICollectionViewControllers inside UIView class.
I cant add the controls.
CGRect viewframes=CGRectMake(0,400,self.view.bounds.size.width,
self.view.bounds.size.height/2);
self.button=[[view2 alloc]initWithFrame:viewframes];
self.button.backgroundColor=[UIColor grayColor];
[self.view addSubview:self.button];

Answer 1

Add UICollectionView control to your xib and set outlet of that and also add it's delegate methods UICollectionViewDataSource and UICollectionViewDelegate to .h file .
Add below code to your .m file
#pragma mark Collection View Methods
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
return UIEdgeInsetsMake(10, 10, 10, 10);
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return [urlArray count];
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
return CGSizeMake(140, 140);
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
GalleryCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"cell" forIndexPath:indexPath];
cell.tag=indexPath.row;
return cell;
}
If you are using custom cell and you want to reload Collection view than add below code
[YourCollectionview registerNib:[UINib nibWithNibName:#"GalleryCell" bundle:nil] forCellWithReuseIdentifier:#"cell"];
[YourCollectionview reloadData];
