Question

Image here

but when those item is active, icon not shown properly:

Image here

Can anyone help me to fix it? I was that it will colour just borders of the icon, not entirely

Answer 1

You need to use UIImageRenderingMode for that.

        UIImage *imgNormal=[UIImage imageNamed:@"normal.png"];
        imgNormal=[imgNormal imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

        UIImage *imgSelected=[UIImage imageNamed:@"active.png"];
        imgSelected=[imgSelected imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        tabBarItem.image = imgNormal; 
        tabBarItem.selectedImage = imgSelected;

Hope it helps :).

• Check this screenshot: At right side of the screen see 'Rendered as' text and select drop down and use Original image. Your problem would be solved. Hope this helps..
