在我的应用程序中,如何按照下图在 tableView 中显示数据。
帮我解决这个问题?
谢谢你。
你可以使用 collectionView 来达到这个目的。因为它看起来像一个网格视图,所以UICollectionView
将是用作网格表的完美选择。
您可以使用RFQuiltLayout库,它是UICollectionView
. 以下是可用于创建布局的代码:
- (void)viewDidLoad {
[_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"cellIdentifier"];
RFQuiltLayout* layout = (id)[self.collectionView collectionViewLayout];
layout.direction = UICollectionViewScrollDirectionVertical;
layout.blockPixels = CGSizeMake(100, 40);
[self.collectionView reloadData];
[super viewDidLoad];
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return 21;
}
// The cell that is returned must be retrieved from a call to -dequeueReusableCellWithReuseIdentifier:forIndexPath:
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier=@"cellIdentifier";
UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
UILabel* label = (id)[cell viewWithTag:21];
if(!label) label=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];
label.backgroundColor=[UIColor blueColor];
label.tag=21;
label.textColor=[UIColor whiteColor];
label.textAlignment=NSTextAlignmentCenter;
[label setAutoresizingMask:(UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth)];
[cell.contentView addSubview:label];
label.text=[NSString stringWithFormat:@"Task%i",indexPath.row];
if (indexPath.row==0) {
label.text=@"Category";
}
if (indexPath.row==3) {
label.text=@"Communication";
}
if (indexPath.row==8) {
label.text=@"Meeting";
}
if (indexPath.row==13) {
label.text=@"Others";
}
[cell setAutoresizesSubviews:YES];
cell.backgroundColor=[UIColor greenColor];
return cell;
}
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
UIEdgeInsets insets=UIEdgeInsetsMake(10, 10, 10, 10);
return insets;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section
{
return 2;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
{
return 2;
}
#pragma mark – RFQuiltLayoutDelegate
- (CGSize) blockSizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row==0)return CGSizeMake(2, 1);
if (indexPath.row==3) return CGSizeMake(2, 2);
if (indexPath.row==8) return CGSizeMake(2, 2);
if (indexPath.row==13) return CGSizeMake(2, 2);
return CGSizeMake(1, 1);
}
- (UIEdgeInsets)insetsForItemAtIndexPath:(NSIndexPath *)indexPath {
return UIEdgeInsetsMake(2, 2, 2, 2);
}
如果你想完全如图显示,请忽略我的回答。您可以使用两个 uitableviews 显示它。首先你需要创建一个表头名称为category的 tableview 必须有两行,即通信和会议。如果用户选择通信,然后导航到第二个表视图中的第二个表视图,每个部分的标题名称是 Mon、tue、Wed、Thur。然后在每一行中显示任务。
