UITableView crash in iOS 8 on heightForHeaderInSection - ios

Question

UITableView in view controller. While reload the tableView two times and click cell it crash with different errors. I declare in .h interface.
{
UITableView *tblRestaurantList;
}
// also change to #property (nonatomic, retain)UITableView *tblRestaurantList;
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 0;
}
error reason : -[UITableViewCell tableView:heightForHeaderInSection:]
error reason : [_UIAppearanceCustomizableClassInfo tableView:heightForHeaderInSection:]
Sometime it shows EXC_BAD_ACCESS(code=EXC_i386_GPFLT) or __NSCFArray or [_CTNativeGlyphStorage tableView:heightForHeaderInSection:].(With 40 line error message)
I change the height to 1.0f, 0.0,0.0001f,1;
I don't what happen its run successfully in iOS 7. I saw many questions in StackOverflow but no one post exact answer.

Answer 1

But why you put 0 in height ??
we can't put 0 here . if you do not want to put height for section, then don't put 0 in height.
This should be some value
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 4; // something like this
}
