Update headerView in the didUpdateLocation

Question

Hi guys I have the following code:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    static NSString *LocationHeaderCellIdentifier = @"Location Header Cell";

    LocationHeaderCell *locationHeaderCell;
    locationHeaderCell = (LocationHeaderCell *)[tableView dequeueReusableCellWithIdentifier:LocationHeaderCellIdentifier];
    locationHeaderCell.lblCurrentAddress.text = self.currentAddress;

    return locationHeaderCell;
}

As you guys can see, I am using a prototype cell to be my header. What I want to accomplish is to access this header in the didUpdateLocation delegate to change a label (refresh it). I do not want to use [reload data] because I am receiving two different responses from different web servers. One from Parse and another from Apple. Therefore I do not know which one will come first. I try to retrieve the header view and it prints Null.

Any suggestions?

You could keep a reference to this LocationHeaderCell in a property for example:

@property(nonatomic, strong) LocationHeaderCell *myHeader;

and modify your code like this:

if (self.myHeader==nil)
    self.myHeader = (LocationHeaderCell *)[tableView dequeueReusableCellWithIdentifier:LocationHeaderCellIdentifier];

so in didUpdateLocation just do a self.myHeader.lblCurrentAddress.text = @whatever";
