Custom table section footer view - label not visible - ios

Question

I created a new Single-view project (using storyboard) in Xcode with a single UITableViewController. Here is the setup code:
- (void)viewDidLoad {
[super viewDidLoad];
_footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 44, 44)];
_footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
UILabel *l = [[UILabel alloc] initWithFrame:CGRectMake(60, 0, 44, 44)];
l.text = #"Label Label Label Label Label Label Label Label Label";
l.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;
l.backgroundColor = [UIColor clearColor];
[_footerView addSubview:l];
_footerView.backgroundColor = [UIColor lightGrayColor];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
return _footerView.frame.size.height;
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
return _footerView;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
return [tableView dequeueReusableCellWithIdentifier:#"Cell"];
}
I want the label in the custom table footer view to be drawn at x = 60, but when I run the project, at first the label is invisible (in portrait, screen attached). Then if I rotate once, it becomes visible and if I rotate back to portrait it's visible.
What am I missing?

You seem to be initialising your footer view with a width and height of 44px, yet adding the label outside of its bounds.
Try the following instead:
_footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.tableView.frame), 44)];
_footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
UILabel *l = [[UILabel alloc] initWithFrame:CGRectInset(_footerView.bounds, 60.0f, 0.0f)];
l.text = #"Label Label Label Label Label Label Label Label Label";
l.autoresizingMask = UIViewAutoresizingFlexibleWidth;
l.backgroundColor = [UIColor clearColor];
[_footerView addSubview:l];
_footerView.backgroundColor = [UIColor lightGrayColor];
As a further point, try not to use [UIColor clearColor] as a label background colour if you can help it - it significantly reduces scrolling performance. In this case you should use [UIColor lightGrayColor] so it matches its superview.
