Add image to a navigationItem's title

问题

I'd like to add a logo to the left of my title on my navigation bar. The title property seems to only take an NSString. What's the best way to add an image to the navigation bar?

回答1:

You can replace the title view with an image like this:

navigationItem.titleView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"title_bar.png"]];   

回答2:

Set UINavigationItem.titleView to a custom view (or just a straight UIImageView).

回答3:

You can customize navigationItem.titleView, class of UIView
