我正在使用UICollectionView来显示一个菜单,并且这些项目正以非常奇怪的方式进行选择.
这是我填写的静态数据：
self.menuItems = @[@{@"text" : @"First",@"image" : @"180-stickynote.png"},@{@"text" : @"Second",@{@"text" : @"Third",@{@"text" : @"Fourth",@{@"text" : @"Fifth",@{@"text" : @"Sixth",@"image" : @"180-stickynote.png"}];
和单元格提供程序,其中自定义子类附加到原型单元格,并具有UILabel和UIImageView：
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
CUMenuCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"MenuCell" forIndexPath:indexPath];
NSDictionary *cellInfo = [self.menuItems objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:[cellInfo valueForKey:@"image"]];
cell.label.text = [cellInfo valueForKey:@"text"];
return cell;
}
- (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"%@: %d",[[self.menuItems objectAtIndex:indexPath.row] valueForKey:@"text"],indexPath.row);
}
最后,我的菜单的屏幕截图：
这是从第一到第六,从第六到第一(第一,第二,第三,第四,第五,第六,第一)的项目的日志(共12个抽头,注意,第一个水龙头甚至没有注册,第六个水龙头也没有)：
