Is it possible to modify uitabbarcontroller height?

Question

我听说，如果您从底部移动选项卡栏，那么您的应用将被拒绝，因为这违反了他们的政策，但是我想修改高度并添加admob横幅视图和一些按钮，如果这样做，将被拒绝？

Answer 1

You can change the tabBar height like this:

CGRect viewFrame=self.tabBar.frame;
        //Sample parameters, add what fits your needs
        viewFrame.origin.y -=30;
   viewFrame.origin.x -=10;
   viewFrame.size.height=150;
   viewFrame.size.width=200;
        self.tabBar.frame=viewFrame;

This is for UITabBar not tabBarController in case you created a tab-based project.

Answer 2

Your app might not be rejected. Just because you change the control object of tab doesn't mean any security issues. For example, apple's own app store app on iPad is a tab bar controller, but the control object is uisegmentcontrol object.

You can hide or change the tab bar in a tab bar controller very easily. The following code should explain it easily.

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    self.tabBar.hidden = YES;

    for(UIView *view in self.view.subviews) {
        if([view isKindOfClass:[UITabBar class]]) {
            [view setFrame:CGRectMake(view.frame.origin.x, self.view.frame.size.height+49, view.frame.size.width, view.frame.size.height)];
        }
        else {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, self.view.frame.size.height)];
        }

    }
}

Also I suggest you give more thought to this method. Container Controllers .

However, if apple rejects you can change things very easily. Don't worry a lot to try something new. Maybe apple will get your idea and pay you some royalty to use even :P.

Answer 3

AFAIK, it's not possible to modify the height. You have to customize the tabbarcontroller to achieve this.

Try the sample project for this in Github.

Answer 4

And what about contentViewController? Because if you change heigth (and move position.y), you should increase viewcontroller size too, isn't it?
