如何在导航栏控制器中的标题旁边放置图像？

Question

I think the first step would be to add an image view. If I have to add any code, please tell me where it belongs. I'm not asking you to go out of your way to tell me how to add the code. I know how to do that. I just want to know where in "UIViewController.h" the code belongs. Oh, and if the image has to be a PNG, please tell me.

Answer 1

Add this code into your viewDidLoad :

UIImage *image = [UIImage imageNamed: @"logo_icon.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(yourXposition, yourYposition, yourWidth, yourHeight);
[self.navigationController.navigationBar addSubview:imageView];

Answer 2

The following code would put an image where the title goes. If you want both, you'll need a UIView that has both the image and a label for title added to it, and then set that UIView as the view in the second line of code below (NOTE: If using ARC remove the autorelease part):

UIImage *image = [UIImage imageNamed:@"image.png"];
self.navigationItem.titleView = [[[UIImageView alloc] initWithImage:image] autorelease];
