突出顯示CollectionView中的單元格

Question

我正在iOS中構建應用程序，我希望CollectionView中的單元格在觸摸時突出顯示，與常規按鈕非常相似。我如何在didSelectItemAtIndexPath中實現這一點：（NSIndexPath *）indexPath方法？

感謝

Answer 1

嘗試是這樣的：

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{ 
    ..... 
    if (cell.selected) { 
     cell.backgroundColor = [UIColor colorWithRed:255/255.0 green:255/255.0 blue:153/255.0 alpha:1]; // highlight selection 
    } 
    else 
    { 
     cell.backgroundColor = [UIColor clearColor]; // Default color 
    } 
    return cell; 
} 

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{ 
    UICollectionViewCell* cell = [collectionView cellForItemAtIndexPath:indexPath]; 
    cell.backgroundColor = [UIColor colorWithRed:255/255.0 green:255/255.0 blue:153/255.0 alpha:1]; //  //cell.lblImgTitle.text = @"xxx"; 
} 

- (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath{ 
    UICollectionViewCell* cell = [collectionView cellForItemAtIndexPath:indexPath]; 
    cell.backgroundColor = [UIColor clearColor]; 
}

試試這個

cell.selectedBackgroundView.backgroundColor = [UIColor greenColor];

如果你的子類的細胞類，把這個在您的.m文件

- (void)setSelected:(BOOL)selected 
{ 
    if(selected) 
    { 
     self.backgroundColor = [UIColor colorWithWhite:0.1 alpha:0.5]; 
    } 
    else 
    { 
     self.backgroundColor = [UIColor whiteColor]; 
    } 
}

爲什麼不能改變通過可可豆莢的背景顏色？我新增了一個用戶自定義的collectionView細胞分類號'

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{ 
     CHSMenuControlCell *cell = (CHSMenuControlCell*)[collectionView cellForItemAtIndexPath:indexPath]; 
     cell.backgroundColor = [UIColor colorWithRed:255/255.0 green:255/255.0 blue:153/255.0 alpha:1]; //  //cell.lblImgTitle.text = @"xxx"; 
    } 

    - (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath{ 
    CHSMenuControlCell *cell = (CHSMenuControlCell *)[collectionView cellForItemAtIndexPath:indexPath]; 
    cell.backgroundColor = [UIColor clearColor]; 
}
