The image below is the original one I want to display:

[![enter image description here](https://i.stack.imgur.com/6a101.png)](https://i.stack.imgur.com/6a101.png)

And I also put the following statement.

```
leftBtn.image = UIImage(named: "logo")

```

However, the image is displayes like the following one. I set the tint color as that dark grey.

Referencing this website [disable tint on custom uibarbuttonitem images](https://stackoverflow.com/questions/22482821/disable-tint-on-custom-uibarbuttonitem-images), I put this statement but it didn't make any change.

```
leftBtn.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)

```

Is there any other way to make the image shown as I want? Any advice would be appreciated!
