[英]Select a Cell in a TableView and changed size
I need to set my UITableView
cells, when I select a cell increases its size to twice, and if I select another this increase in size and decrease that was previously selected size. 我需要设置我的UITableView
单元格,当我选择一个单元格时,它将其大小增加到两倍,如果我选择了另一个,则该大小增加并减小了以前选择的大小。
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.states count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpleTableIdentifier = @"SimpleTableCell";
SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.stateName.text = [self.states objectAtIndex:indexPath.row];
return cell;
}
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 40;
}
@end
If you are using autolayout then simply add 如果您使用的是自动布局,则只需添加
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
// for particular index
return UITableViewAutomaticDimension;
}
and if not using autolayout then 如果不使用自动布局
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 1){
return 80;
}else{
return 44;
}
}
Take 采取
one property selectedIndexPath 一个属性selectedIndexPath
@property (strong, nonatomic) NSIndexPath * selectedIndexPath;
set that in 设置在
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
selectedIndexPath = indexPath;
[tableView reloadData];
}
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(selectedIndexPath != nil && indexPath == selectedIndexPath){
return 80;
}
return 40;
}
