kvc get subview lastobject - ios

Question

I have a problem.
first,I have a NSArray like this:
(NSMutableArray *)currentCanMoveAndDeleteCellArray {
NSInteger count = [self.contentCollectionView numberOfItemsInSection:0];
NSMutableArray *currentCells = [NSMutableArray arrayWithCapacity:count];
for (int index = 0 ; index < count; ++index) {
UICollectionViewCell *cell = [self.contentCollectionView cellForItemAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]];
if(cell) {
[currentCells addObject:[self.contentCollectionView cellForItemAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]]];
}
}
return currentCells;
}
then I want to get their last subviews, I use kvc get subviews like this.
[self.currentCanMoveAndDeleteCellArray valueForKeyPath:#"subviews"]
and I got:
<__NSArrayI 0x1710793c0>(
<__NSArrayM 0x17405a670>(
<UIView: 0x155de9020; frame = (0 0; 80 30); gestureRecognizers = <NSArray: 0x170248f40>; layer = <CALayer: 0x1702363a0>>,

)
)
who can tell me how to got last subview.
I tried to write:
[self.currentCanMoveAndDeleteCellArray valueForKeyPath:#"subviews.#lastObject"]
but, you know that it isn't result that i want.

Answer 1

You should use UICollectionViewCell class in array.
After, you can get subview.
- (NSMutableArray *)currentCanMoveAndDeleteCellArray {
NSInteger count = [self.contentCollectionView numberOfItemsInSection:0];
self.currentCells = [NSMutableArray arrayWithCapacity:count];
for (int index = 0 ; index < count; ++index) {
UICollectionViewCell *cell = [self.contentCollectionView cellForItemAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]];
if(cell) {
[ self.currentCells addObject:cell]; }
} return self.currentCells;
}
-(void)getCell{
UICollectionViewCell *cell = [ self.currentCells objectAtIndex:_index];
for (UIView * view in [cell subviews]) {
NSLog(#"%#",view);
}
}
