实际效果图：
定义属性
@property (nonatomic, assign) BOOL isSelect; // 判断是否选择
@property (nonatomic, assign) NSInteger currentSection;//当前选择的(section)
@property (nonatomic, assign) NSInteger currentIndex;//当前选择的（row）
@property (nonatomic, assign) NSInteger lastCurrentSection;//上一次打开的（section）
@property (nonatomic, assign) NSInteger lastCurrentIndex;//上一次打开的（row）
首先初始化值： 这个随便了只要不与当前的tableView里的scetion 和 row 重复就行
self.isSelect = YES;
self.currentIndex = -1;
self.currentSection = 0;
self.lastCurrentSection = -2;
self.lastCurrentIndex = -2;
其次是返回cell的行高
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
// NSDictionary *dic = self.dataSource[indexPath.section];
// NSArray *array = dic[@"sList"];
// NSDictionary *dic = self.dataSource[indexPath.section];
// NSArray *array = dic[@"sList"];
//
// CGRect titleRect = [array[indexPath.row][@"sTitle"] boundingRectWithSize:CGSizeMake(MAINSCREEN_SIZE.width - 53, 10000) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading | NSStringDrawingUsesDeviceMetrics attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15]} context:nil];
//
// CGRect contentRect = [array[indexPath.row][@"sIntro"] boundingRectWithSize:CGSizeMake(MAINSCREEN_SIZE.width - 63, 10000) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading | NSStringDrawingUsesDeviceMetrics attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12]} context:nil];
根据选择返回高度
if (indexPath.row == _currentIndex && indexPath.section == _currentSection) {
if (self.isSelect == YES) {
把当前的选择保存下来
_currentIndex = indexPath.row;
_currentSection = indexPath.section;
返回当前实际需要的高度
return titleRect.size.height + contentRect.size.height + 80;
}
返回正常的高度
return titleRect.size.height + 50;
}else{
返回正常的高度
return titleRect.size.height + 50;
}
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
//判断选中状态
if (indexPath.row == self.currentIndex && indexPath.section == self.currentSection) {
判断是否为新打开的一个选项
if (self.isSelect == YES) {
打开状态的设置
cell.titleLable.textColor = GetColor(17, 180, 187, 1);
cell.round.backgroundColor = GetColor(17, 180, 187, 1);
cell.backgroundColor = GetColor(230, 230, 230, 1);
cell.line.backgroundColor = GetColor(17, 180, 187, 1);
cell.contentLable.hidden = NO;
cell.linkBut.hidden = NO;
} else {
恢复默认状态
cell.titleLable.textColor = [UIColor blackColor];
cell.round.backgroundColor = [UIColor blackColor];
cell.backgroundColor = [UIColor whiteColor];
cell.line.backgroundColor = [UIColor grayColor];
}
}else{
不选中的都为默认状态
cell.titleLable.textColor = [UIColor blackColor];
cell.round.backgroundColor = [UIColor blackColor];
cell.backgroundColor = [UIColor whiteColor];
cell.line.backgroundColor = [UIColor grayColor];
}
让上一次恢复默认状态
if (indexPath.section == self.lastCurrentSection && indexPath.row == self.lastCurrentIndex ) {
cell.titleLable.textColor = [UIColor blackColor];
cell.round.backgroundColor = [UIColor blackColor];
cell.backgroundColor = [UIColor whiteColor];
cell.line.backgroundColor = [UIColor grayColor];
cell.contentLable.hidden = YES;
cell.linkBut.hidden = YES;
}
}
选择点击事件
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
判断当前的选择
if (indexPath.row == _currentIndex && indexPath.section == _currentSection) {
选择状态置为非
self.isSelect = ! self.isSelect;
}else{
记住上一行并刷新
self.lastCurrentIndex = _currentIndex;
self.lastCurrentSection = _currentSection;
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:_currentIndex inSection:self.lastCurrentSection];
[tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
选择状态恢复默认
self.isSelect = YES;
}
刷新当前选择行
_currentIndex = indexPath.row;
_currentSection = indexPath.section;
NSIndexPath *indexPathOne=[NSIndexPath indexPathForRow:_currentIndex inSection:_currentSection];
[tableView reloadRowsAtIndexPaths:@[indexPathOne] withRowAnimation:UITableViewRowAnimationAutomatic];
}
