Define Size

Layout.itemsize = Cgsizemake ((appWidth-40)/2.0, 0.8* (appWidth-40)/2.0);

Set Minimum line spacing

layout.minimumlinespacing = 10;

Set Vertical Spacing

layout.minimuminteritemspacing = 10;

Layout.sectioninset = Uiedgeinsetsmake (15, 15, 15, 15);

Set Vertical Spacing

layout.headerreferencesize = cgsizemake (0, 0);

Set scrolling direction (default vertical scrolling)

Layout.scrolldirection = uicollectionviewscrolldirectionvertical;

_collectionview = [[Uicollectionview alloc] Initwithframe:cgrectmake (0, 0, appwidth, appHeight-64) Collectionviewlayout:layout];

_collectionview.backgroundcolor = [Uicolor Clearcolor];

_collectionview.delegate = self;

Nsindexpath *indexpath = [Nsindexpath indexPathForRow:sender.tag insection:0];

Homecollectionviewcell *cell = (homecollectionviewcell*) [Self.collectionview Cellforitematindexpath:indexpath];

In this case, look for a sub-view in the view (this looks, possibly because there are more than two views in the parent view)

Nsinteger fist= [[Cell subviews] Indexofobject:[cell viewwithtag:1000]];

Nsinteger seconde= [[Cell subviews] Indexofobject:[cell viewwithtag:2000]];

model* model = Self.dataarray[indexpath.item];

3, 3D Flip Animation

[UIView animatewithduration:1.0 animations:^{

if (Model.select = = YES)

{

Cell.firstview.hidden = YES;

Model.select = NO;

[Self.dataarray ReplaceObjectAtIndex:indexPath.item withobject:model];//is currently showing a positive view

[UIView setanimationtransition:uiviewanimationtransitionflipfromright Forview:cell Cache:yes];

}

Else

{

Cell.secondView.hidden = YES;

Cell.firstview.hidden = NO;

Model.select = YES;

[Self.dataarray ReplaceObjectAtIndex:indexPath.item withobject:model];//is currently showing the back view

[UIView setanimationtransition:uiviewanimationtransitionflipfromleft Forview:cell Cache:yes];
