I am trying to customize my tableView in my IOS app. When my tableView(or rather array) is empty, I want to display a customized label instead of the items in the tableView. The label I am referring to is "label0". But something is terribly wrong, my [label0 setHidden:YES]; or [label0 setHidden:NO]; only works in the first block of the if "method"? In the second block (if else) nothing happens no matter what I try to set the label as (hidden or shown).
What have I missed? I cannot see my own fault?
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
UILabel *label0 = [[[UILabel alloc] initWithFrame:CGRectMake(0, 25, tableView.bounds.size.width - 0, 100)] autorelease];
if ([self.searchResults count] == 0){
headerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lista2.png"]];
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(5, 3, tableView.bounds.size.width - 5, 18)] autorelease];
label.text = @"Information";
label.textColor = [UIColor whiteColor];
label.backgroundColor = [UIColor clearColor];
[headerView addSubview:label];
label0.text = @"Test test test";
label0.textColor = [UIColor blackColor];
label0.backgroundColor = [UIColor whiteColor];
[tableView addSubview:label0];
[label0 setHidden:NO];
}
else {
headerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"lista2.png"]];
UILabel *label2 = [[[UILabel alloc] initWithFrame:CGRectMake(5, 3, tableView.bounds.size.width - 5, 18)] autorelease];
label2.text = @"Search results";
label2.textColor = [UIColor whiteColor];
label2.backgroundColor = [UIColor clearColor];
[headerView addSubview:label2];
[label0 setHidden:YES];
}
return headerView;
}
EDIT
I have moved the code to viewDidLoad and set the property for the UILabel. This have unfortunately not solved my problem....
UILabel *label0 = [[[UILabel alloc] initWithFrame:CGRectMake(0, 25, tableView.bounds.size.width - 0, 100)] autorelease];
[tableView addSubview:label0];
if ([self.searchResults count] == 0){
label0.text = @"Test test test";
label0.textColor = [UIColor blackColor];
label0.backgroundColor = [UIColor whiteColor];
[label0 setHidden:NO];
}
else {
[label0 setHidden:YES];
}
