Change frame programmatically with auto layout

One more thing, you have to call [self.view layoutIfNeeded]; method once you changne the constraints.

Enjoy :)

Let your UITableView constraints to bottom layout is set to 0, make an IBOutlet. Now let your GADBannerView height is 40 so change your outlet.constant = 40; For more about how to make IBOutlet and change its value have a look into this or this hope this will help.

Edit: For those who seeking for example, follow these simple steps (Because this is accepted answer, I think it is worth to have an example. Credit to @manujmv for this example)

1. Create a height constraint for your view in your interface.

2. Then add an IBOutlet object in your class for this constraint. For example:

   @property (weak, nonatomic) IBOutlet NSLayoutConstraint *heightConstraint;

Connect this object in your connection panel.

3. Then change the value of this constraint whenever you needed

   self.heightConstraint.constant = 40;

Rather than trying to change the frame of the view, add a height constraint using auto layout and reduce the value of this constraint. Do the below steps:

1. create a height constarint for your view in your interface.

2. Then add an IBOutlet object in your class for this constraint. for example,

    @property (weak, nonatomic) IBOutlet NSLayoutConstraint *heightConstraint;
   

   Connect this object in your connection panel.

3. Then change the value of this constraint whenever you needed

    self.heightConstraint.constant = 40;
