I don't know why viewForHeaderInSection
is not called in swift3. I've added heightForHeaderInSection
in UITableView but not called unfortunately. Please help me to check how to fixed it.
func numberOfSectionsInTableView(_ tableView: UITableView) -> Int {
return 3
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
switch (section) {
case 0:
return homeStrs.count
case 1:
return accountStrs.count
case 2:
return otherStrs.count
default:
return otherStrs.count
}
}
func tableView(_ tableView: UITableView, cellForRowAtIndexPath indexPath: IndexPath) -> UITableViewCell {
let cell = menuTable.dequeueReusableCell(withIdentifier: "MenuCell", for: indexPath) as! MenuCell
cell.layoutMargins = UIEdgeInsets.zero;
cell.lbNoti.isHidden = true
switch ((indexPath as NSIndexPath).section) {
case 0:
cell.lbMenuTitle?.text = homeStrs[(indexPath as NSIndexPath).row]
cell.imgIcon.image = UIImage (named: homeImgStrs[(indexPath as NSIndexPath).row])
case 1:
cell.lbMenuTitle?.text = accountStrs[(indexPath as NSIndexPath).row]
cell.imgIcon.image = UIImage (named: accountImgStrs[(indexPath as NSIndexPath).row])
case 2:
cell.lbMenuTitle?.text = otherStrs[(indexPath as NSIndexPath).row]
cell.imgIcon.image = UIImage (named: otherImgStrs[(indexPath as NSIndexPath).row])
default:
cell.lbMenuTitle?.text = "Other"
}
return cell
}
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 40
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
switch (section) {
case 1:
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: self.menuTable.frame.size.width, height: 30))
let menuHeaderLabel = UILabel(frame: CGRect(x: 20, y: 0, width: self.menuTable.frame.size.width, height: 28))
menuHeaderLabel.text = "Account Settings"
headerView.addSubview(menuHeaderLabel)
return headerView
case 2:
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: self.menuTable.frame.size.width, height: 30))
let menuHeaderLabel = UILabel(frame: CGRect(x: 20, y: 0, width: self.menuTable.frame.size.width, height: 28))
menuHeaderLabel.text = "Others"
headerView.addSubview(menuHeaderLabel)
return headerView
default:
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: self.menuTable.frame.size.width, height: 0))
return headerView
}
}
If someone else is having the same issue... Adding this line in viewDidLoad called the delegate methods therefore made the header appear:
self.tableView.estimatedSectionHeaderHeight = 80
You sure you've added UITableViewDelegate, UITableViewDataSource in your ViewController Class
In my case, adding self.tableView.sectionHeaderHeight = 80.0
to viewDidLoad did the magic.
Same issue occured with me that's because tableview find difficulties in calculating height for header but as I was using automatic height calculation from xCode 9, I cannot give any explicit height value as mentioned above. After some experimentation I got solution, we have to override this method as,
-(CGFloat)tableView:(UITableView *)tableView
estimatedHeightForHeaderInSection:(NSInteger)section
{
return 44.0f;
}
Although I have checked both options
from storyboard as apple says, but still I got this weird error.
Please Note: This Error was shown only on IOS-10 version not on IOS-11 version. Maybe it's a bug from xCode. Thanks
