How come the icon info.png stays blue and don't comes with the original color of that image? I am using the following code below:

style:UIBarButtonItemStylePlain
target:self
action:@selector(info:)];

By default, image in UINavigationBar's bar button items is rendered using template mode. You can set it to original.
默认情况下，UINavigationBar 的栏按钮项中的图像使用模板模式呈现。您可以将其设置为原始。
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[[UIImage imageNamed:@"info.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
style:UIBarButtonItemStylePlain
target:self
action:@selector(info:)];

You can it from assets as well. Go to Assets.xcassets >> Select the image that is being used as barbutton item image. Tap on attribute inspector in right side panel. Choose render as to orignial image. It will be default earlier. You will now see colored image.
您也可以从资产中获取。转到 Assets.xcassets >> 选择用作栏按钮项目图像的图像。点击右侧面板中的属性检查器。选择渲染为原始图像。之前会默认。您现在将看到彩色图像。

For Swift 2.1+ it would look like this:
对于 Swift 2.1+，它看起来像这样：
let image : UIImage? = UIImage(named:"myImage.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
or simply
或者干脆
let image : UIImage? = UIImage(named:"myImage.png")!.imageWithRenderingMode(.AlwaysOriginal)

Because the color of barButtonItems in your app is related to the tintColor property on the application's window.
因为应用程序中 barButtonItems 的颜色与应用程序窗口上的 tintColor 属性有关。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window.tintColor = [UIColor redColor];
return YES;
}

Ok, got it... I set the image to it's original state first.
好的，明白了...我首先将图像设置为原始状态。
UIImage *image = [[UIImage imageNamed:@"info.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:image
style:UIBarButtonItemStylePlain
target:self
action:@selector(info:)];

Change the bar button item tint color from the storyboard. Or color from the image in storyboard.
从故事板更改条形按钮项的色调颜色。或者从故事板中的图像颜色。
The color should be your expected color as hex or rgb.
颜色应该是您期望的颜色，如十六进制或 rgb。
