Tab Bar covers TableView cells in iOS7 - objective-c

Question

I have a custom tableViewController that I'm adding to a TabBarController with
self.tabBarController.viewControllers = [NSArray arrayWithObjects:someOtherViewController, customTableViewController, nil];
self.tabBarController.selectedIndex = 1;
The issue I'm having is that the last 1.5 tableViewCells are being covered by the tab bar at the bottom of the screen on an iPhone 4 running iOS7. When I use the iOS Simulator - iPhone Retina (4-inch) / iOS 7.0 the issue still exists.
What is the correct way to make the tableView line up with the top of the tabBar at the bottom of the screen without using 'magic numbers'?

Answer 1

Try this for your CustomViewController:
- (void)viewDidLoad
{
[super viewDidLoad];
UIEdgeInsets adjustForTabbarInsets = UIEdgeInsetsMake(0, 0, CGRectGetHeight(self.tabBarController.tabBar.frame), 0);
self.scrollView.contentInset = adjustForTabbarInsets;
self.scrollView.scrollIndicatorInsets = adjustForTabbarInsets;
}

Answer 2

It's an iOS 8 solution but it may work on iOS 7 to: Go to storyboard > select table view controller > uncheck "Under Bottom Bars". That's it!

Answer 3

Setting the contentInset of your table view with a .bottom value of 49 points should correct this.
Under the right configurations, setting YES for the new UIViewController property on iOS 7 called automaticallyAdjustsScrollViewInsets should correct this, but (again) it depends upon a lot of other factors (view hierarchy, parent view controller's settings, et cetera).

Answer 4

The accepted answer doesn't quite work for me--my set up is a little different. I'm programatically creating my view controllers. My app's root is a tab bar controller, one tab is a navigation controller, whose root is a UIViewController with a table view as the main view.
What works for me though is when I manually computed the table view's height and set it in the frame when alloc-initing the table view. The general formula is:
screen height - (status bar height + nav bar height + tab bar height)

Answer 5

CGFloat bottom = self.tabBarController.tabBar.frame.size.height;
NSLog(#"%f",bottom);
[self.tableview setScrollIndicatorInsets:UIEdgeInsetsMake(0, 0, bottom, 0)];
self.tableview.contentInset = UIEdgeInsetsMake(0, 0, bottom, 0);

Answer 6

Embed your table controller in a navigation controller.
1. select the view in story board.
2. On menu bar select Editor -> embed in -> navigation controller.
Hope that helps

Answer 7

I have a similar view hierarchy to Matt Quiros: UITabBarController -> UINavigationController -> UIViewController -> UITableViewController (embedded as a subview of the UIViewController). The other answers didn't work in my case, and I had to set the table view's frame manually in the table view controller's viewWillAppear: method.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// Adjust height of tableview (does not resize correctly in iOS 7)
CGRect tableViewFrame = self.tableView.frame;
tableViewFrame.size.height = [self heightForTableView];
self.tableView.frame = tableViewFrame;
}
- (CGFloat)heightForTableView
{
return CGRectGetHeight([[UIScreen mainScreen] bounds]) -
(CGRectGetHeight([[UIApplication sharedApplication] statusBarFrame]) +
CGRectGetHeight(self.navigationController.navigationBar.frame) +
CGRectGetHeight(self.tabBarController.tabBar.frame));
}
If anyone finds a better solution, please share!

Answer 8

I think this would work better for you:
After [super viewDidLoad];
try the following code:
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;

Answer 9

You can also implement viewDidLayoutSubviews and use bottomLayoutGuide to get the height of the tab bar:
- (void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
CGFloat bottomOffset = self.bottomLayoutGuide.length;
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, bottomOffset, 0);
}

Answer 10

Even though changing the contentInset of your table View is a working solution, I find it better to make sure your table view stops before the Tabbar.
As Paul Newman said, using the bottomLayoutGuide is a good thing, specially if you are using autolayout.
In My case adding a constraint to the bottom of the tableview linking to the top of the BottomLayoutGuide was a clean solution, this is an example with Storyboard, but it can be done in code as well.
Hope it helps.
