UITabBar background image not showing properly


I made custom UITabBar class and tried to set background image.

tabBar.backgroundImage = UIImage(named: "my_image")?.imageWithRenderingMode(.AlwaysOriginal)

I set the image file name to my_image@2x and image file is 640*98

I run on iPhone6 simulator and it seems the image is not wide enough like Google's "C" is repeated on sample below

enter image description here

Im I using wrong image size or is something else is wrong?


Solution

  • Just redraw the image:

    var image = UIImage(named: "my_image")
    if let image = image {
        var centerImage: Bool = false
        var resizeImage: UIImage?
        let size = CGSize(width: UIScreen.mainScreen().bounds.size.width, height: 98)
        UIGraphicsBeginImageContextWithOptions(size, false, 0)
        if centerImage {
            //if you want to center image, use this code
            image.drawInRect(CGRect(origin: CGPoint(x: (size.width-image.size.width)/2, y: 0), size: image.size))
        }
        else {
            //stretch image
            image.drawInRect(CGRect(origin: CGPoint.zero, size: size))
        }
        resizeImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        tabBar.backgroundImage = resizeImage.imageWithRenderingMode(.AlwaysOriginal)
    }
