透明的UITabBar

Question

I have subclassed UITabBar and I need it to be transparent. Like This:

I have tried : [[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:79.0f/255.0 green:53.0f/255.0 blue:98.0f/255.0 alpha:0.6f]];

It only changed The bar's color, but The bar is still not transparent.

Please help. I have tried lots of different methods, but none of them worked.

Answer 1

Try this

//  The color you want the tab bar to be
UIColor *barColor = [UIColor colorWithRed:79.0f/255.0 green:53.0f/255.0 blue:98.0f/255.0 alpha:0.6f];

//  Create a 1x1 image from this color
UIGraphicsBeginImageContext(CGSizeMake(1, 1));
[barColor set];
UIRectFill(CGRectMake(0, 0, 1, 1));
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

//  Apply it to the tab bar
[[UITabBar appearance] setBackgroundImage:image];

Here's the result

Here is a solution based on AnupamChugh's answer

1. Create an IBOutlet for the tab bar in the UITabBarController

2. Use that to set the tab bar as transparent

    class AppTabBarController: UITabBarController { @IBOutlet weak var mTabBar: UITabBar! override func viewDidLoad() { super.viewDidLoad() mTabBar.backgroundColor = UIColor.clear mTabBar.backgroundImage = UIImage() mTabBar.shadowImage = UIImage() // removes the border 

Answer 3

UITabBar.appearance().backgroundColor=UIColor.clearColor()
UITabBar.backgroundImage = UIImage()

Answer 4

This kind of design is the default since iOS7. Try this:
