Setting the titleView of your view's navigationItem will never do the trick. Instead, you can add a subView to the navigation controller's navigationBar :

<pre><code>UIView* ctrl = [[UIView alloc] initWithFrame:navController.navigationBar.bounds];
ctrl.backgroundColor = [UIColor yellowColor];
ctrl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[navController.navigationBar addSubview:ctrl];
</code></pre>

if you want to set image then take uiimage view instead on uilable you can create any view of fully navigation bar just tell me how ur navigation look like i will send you code for that if you want i can put 6 button on navigation also

blocks|key|925007|text|只是遇到了同样的问题，经过一点思考就解决了。titleView的框架在每次出现时都由navigationBar设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|925008|你所要做的就是继承UIView的子类并覆盖setFrame。|offset|length|style|CODE|925009|如下所示：|925010|++++-+(void)setFrame:(CGRect)frame+{

Just ran into the same problem and after a bit of thinking solved it. titleView's frame gets set by the navigationBar every time it appears. 

All you have to do is subclass UIView and override <code>setFrame</code>.

Like this:

<pre><code> - (void)setFrame:(CGRect)frame {
 [super setFrame:CGRectMake(0.0, 0.0, 320.0, 50.0)];
 }
</code></pre>

Now set your sneaky new UIView as the <code>navigationItem.titleView</code> and enjoy its newfound resistance to resizing by the superview. 

You don't have to set super's frame every time your frame gets set. You can just set it once and be done. If you want to support orientation changes you could probably hack that together too.

Swift version of ksm's answer

<pre><code>let leftOffset: CGFloat = 60
let rightOffset: CGFloat = 60

@objc override var frame: CGRect {
 didSet {
 let width: CGFloat = UIScreen.main.bounds.width - leftOffset - rightOffset
 let height: CGFloat = 44

 super.frame = CGRect(
 x: leftOffset,
 y: 20,
 width: width,
 height: height
 )
 }
}
</code></pre>

I am trying to add a custom control as the titleView in a UINavigationBar. When I do so, despite setting the frame and the properties that would normally assume full width, I get this:
<img src="https://i.stack.imgur.com/NNgHb.png" alt="alt text">

The bright blue can be ignored as it is where I am hiding my custom control. The issue is the narrow strips of navbar at the ends of the bar. How can I get rid of these so my customview will stretch 100%?

<pre><code>CGRect frame = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.width, kDefaultBarHeight);
UANavBarControlView *control = [[[UANavBarControlView alloc] initWithFrame:frame] autorelease];
control.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
self.navigationItem.titleView = control;
</code></pre>

PS - I know I can add the view by itself instead of being attached to a navigation bar and it would be very easy to position it myself. I have my reasons for needing it to be "on" the navigation bar, and those reasons are <a href="https://stackoverflow.com/questions/3747991/uisearchbar-animating-of-top-of-another-uiview-besides-uinavigationbar">here</a>

How can I get a full-sized UINavigationBar titleView

Swift

我正在尝试添加一个自定义控件作为UINavigationBar中的titleView。当我这样做时，尽管设置了框架和通常假定为全宽的属性，但我得到的结果是：​可以忽略亮蓝色，因为它是我隐藏自定义控件的位置。问题是导航栏末端的窄条。我怎样才能去掉这些，这样我的自定义视图才能100%伸展？CGRect frame = CG...
