YUFoldingTableView
可快速集成UITableView的折叠cell
详情请参考简书
#效果：
使用步骤
1.导入头文件，遵守协议
#import "ViewController.h"
#import "YUFoldingTableView.h"
@interface ViewController () <YUFoldingTableViewDelegate>
@property (nonatomic, weak) YUFoldingTableView *foldingTableView;
@end
2.创建YUFoldingTableView
self.automaticallyAdjustsScrollViewInsets = NO;
YUFoldingTableView *foldingTableView = [[YUFoldingTableView alloc] initWithFrame:CGRectMake(0, 64, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height - 64)];
_foldingTableView = foldingTableView;
[self.view addSubview:foldingTableView];
foldingTableView.foldingDelegate = self;
// 可以设置cell默认展开，不设置的话，默认折叠
foldingTableView.foldingState = YUFoldingSectionStateShow;
3.实现YUFoldingTableView的代理，用法和UItableView类似
#pragma mark - YUFoldingTableViewDelegate / required（必须实现的代理）
- (NSInteger )numberOfSectionForYUFoldingTableView:(YUFoldingTableView *)yuTableView
{
return 5;
}
- (NSInteger )yuFoldingTableView:(YUFoldingTableView *)yuTableView numberOfRowsInSection:(NSInteger )section
{
return 3;
}
- (CGFloat )yuFoldingTableView:(YUFoldingTableView *)yuTableView heightForHeaderInSection:(NSInteger )section
{
return 50;
}
- (CGFloat )yuFoldingTableView:(YUFoldingTableView *)yuTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 50;
}
- (UITableViewCell *)yuFoldingTableView:(YUFoldingTableView *)yuTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = @"cellID";
UITableViewCell *cell = [yuTableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
cell.textLabel.text = [NSString stringWithFormat:@"Row %ld",indexPath.row];
return cell;
}
#pragma mark - YUFoldingTableViewDelegate / optional （可选择实现的）
// 自定义sectionHeaderView
- (UIView *)yuFoldingTableView:(UITableView *)yuTableView viewForHeaderInSection:(NSInteger)section
{
static NSString *headerIdentifier = @"headerIdentifier";
YUCustomHeaderView *headerFooterView = [yuTableView dequeueReusableHeaderFooterViewWithIdentifier:headerIdentifier];
if (headerFooterView == nil) {
headerFooterView = [[YUCustomHeaderView alloc] initWithReuseIdentifier:headerIdentifier];
}
headerFooterView.contentView.backgroundColor = [UIColor colorWithRed:200/255.0 green:200/255.0 blue:200/255.0 alpha:0.2];
headerFooterView.title = [NSString stringWithFormat:@"标题 - %ld", section];
headerFooterView.descriptionText = [NSString stringWithFormat:@"自定义的sectionHeaderView - %ld", section];
return headerFooterView;
}
- (NSString *)yuFoldingTableView:(YUFoldingTableView *)yuTableView titleForHeaderInSection:(NSInteger)section
{
return [NSString stringWithFormat:@"Title %ld",section];
}
// 返回箭头的位置
- (YUFoldingSectionHeaderArrowPosition)perferedArrowPositionForYUFoldingTableView:(YUFoldingTableView *)yuTableView
{
return YUFoldingSectionHeaderArrowPositionLeft;
}
- (void )yuFoldingTableView:(YUFoldingTableView *)yuTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[yuTableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (NSString *)yuFoldingTableView:(YUFoldingTableView *)yuTableView descriptionForHeaderInSection:(NSInteger )section
{
return @"detailText";
}
