Seems I am having difficulty with something as simple as icons.
I am building an app for iOS7 only and thus, devices are retina displays (excluding iPad 2). So I made u
Keep 60x60px icons but rename them as iconName@2x.png which iOS will automatically reduce to 30x30 points, roughly to half of the original size on retina devices.
If you are using assets catalogue, please make sure your icons are set to 2x icon sets.
Or you can do something like this:
UIImage *image = [UIImage imageNamed:@"1.jpg"];
[image drawInRect:CGRectMake(0, 0, 30, 30)];
first.tabBarItem.image = image;
