提问by Bug

这是我的原始图像。
And after adding that image on navigation bar button item than it look like this

First, I agree with @Desdenova's comment.
The two images do not look the same, one has hard right angle edges for each line, and the other rounded.
Make sure you are using the correct image file.
If this is the case, awesome, problem solved without deviating from your xibimplementation. If not, just do it programmatically (as per @shankars code).
But another thing to note, I've run into problems setting custom image files to buttons, where the image gets tweaked... make sure to use UIImageRenderingModeAlwaysOriginalwhen setting the image to the button:
首先，我同意@Desdenova 的评论。
两个图像看起来不一样，一个图像的每条线都有硬直角边缘，另一个是圆形的。
确保您使用的是正确的图像文件。
如果是这种情况，真棒，问题解决了，而不会偏离您的xib实现。如果没有，只需以编程方式进行（根据@shankars 代码）。
但另一件要注意的事情是，我在将自定义图像文件设置为按钮时遇到了问题，其中图像会被调整......确保UIImageRenderingModeAlwaysOriginal在将图像设置为按钮时使用：
Objective-C:
目标-C：
[button setImage:[[UIImage imageNamed:@"imageName.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] forState:UIControlStateNormal];
Swift:
迅速：
someBarButtonItem.image = UIImage(named: "yourPictureName")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
Swift 3:
斯威夫特 3：
someBarButtonItem.image = UIImage(named:"myImage")?.withRenderingMode(.alwaysOriginal)

This is sample working code
这是示例工作代码
UIImage *myImage = [UIImage imageNamed:@"myImageFile.png"];
myImage = [myImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIBarButtonItem *menuButton = [[UIBarButtonItem alloc] initWithImage:myImage style:UIBarButtonItemStylePlain target:self action:@selector(menuObject:)];
self.navigationItem.leftBarButtonItem = menuButton;

Hopefully I am not too late to add an answer of my own, but within Assets.xcassets, you can click on your image and in the attributes inspector, under Rendar Asset it to Original Image
希望我不会太晚添加我自己的答案，但是在 Assets.xcassets 中，您可以单击您的图像并在属性检查器中，在Rendar As 下将其设置为Original Image

You can create navigation bar button programmatically instead of direct storyboard, this will not affect original image color
您可以以编程方式创建导航栏按钮而不是直接故事板，这不会影响原始图像颜色
self.navigationItem.leftBarButtonItem=[self backButton];
- (UIBarButtonItem *)backButton
{
UIImage *image = [UIImage imageNamed:@"image.png"];
CGRect buttonFrame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton *button = [[UIButton alloc] initWithFrame:buttonFrame];
//[button addTarget:self action:@selector(backButtonPressed) forControlEvents:UIControlEventTouchUpInside];
[button setImage:image forState:UIControlStateNormal];
UIBarButtonItem *item= [[UIBarButtonItem alloc] initWithCustomView:button];
return item;
}

You need to set tint color as well - which worked for me - You can generate UIBarButtonItem via code as follows:
您还需要设置色调颜色 - 这对我有用 - 您可以通过代码生成 UIBarButtonItem 如下：
#define setTurqoiseColor [UIColor colorWithRed:68.0f/255.0f green:181.0f/255.0f blue:223.0f/255.0f alpha:1.0]
UIBarButtonItem *menuButton = [[UIBarButtonItem alloc] initWithImage:buttonImage style:UIBarButtonItemStyleBordered target:self action:@selector(toggleMenu)];
menuButton.tintColor = setTurqoiseColor;
