objective-c - How to set the size of the picture on UITabBarItem

Question

As shown in the picture, the tabbarController created with storyboard, how to set the image size?

Answer 1

There are three solutions. The first is to directly resize the original image. However, the icon will be blurred when running on a real machine, so it is not recommended. The second is to draw the image proportionally, which is more troublesome. The third method, which is also my recommendation, is to modify the title on the original image, such as message@2x.png. . x is lowercase, this involves the difference between @2x and @3x,,

Answer 2

TabbarItem pictures cannot be manually set in size. Your picture is too big

Answer 3

The picture I made is too big.
