如何在导航栏中放置 UIImage 使其成为徽标?

问题描述

我想在 NavigationBar 的左侧放置一个徽标/图像.我在代码中尝试了这个，但它不能正常工作.

I would like to place a logo/image in the left side of NavigationBar. I try this in codes, but it is not worked properly.

UIImage *logo = [UIImage imageNamed:@"logo.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: logo];
imageView.frame = CGRectMake(2, 2, 40, 40);
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:logo];

我尝试先放置视图，然后将图像放置为 UIImageView，但对齐不好.而且在运行代码时视图似乎是空白...

I try with view to be placed first then place image as UIImageView but alignment is not good. And moreover view appears to be white space while run the code..

推荐答案

将Bar Button Item插入到左侧的Viewcontroller中，并在Bar item看图

Insert the Bar Button Item into your Viewcontroller on left Side, and insert the image in Bar item see the image
