There is no particularly good way to do this. Your best bet if you really must is to subclass UINavigationBar, and override <code>layoutSubviews</code> to call <code>[super layoutSubviews]</code> and then find and reposition the button's view.

blocks|key|704925|text|这里有一个简单的解决方法，足以满足我的需求。我在UINavigationBar的右手边添加了一个信息按钮，但默认情况下它离边缘太近了。通过延长框架的宽度，我能够在右侧创建所需的额外间距。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704926|+UIButton+*info+=+[UIButton+buttonWithType:UIButtonTypeInfoLight];

Here is a simple workaround that was sufficient for my needs. I added an info button on the right hand side of the UINavigationBar but by default it sits way too close to the edge. By extending the width of the frame I was able to create the extra spacing needed on the right.

<pre><code> UIButton *info = [UIButton buttonWithType:UIButtonTypeInfoLight];
 CGRect frame = info.frame;
 frame.size.width += 20;
 info.frame = frame;
 myNavigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]initWithCustomView:info]autorelease];

Its used to change the 'y' position in this code. Change the 'y' value (here it is -20.0f) according to your requirement. If the value is positive, it will down the button position. If the value is negative, it will up your button position.

The best solution I could find is to initialize a UIBarButtonItem with a subview that includes extra space to the left/right. That way you wont have to worry about subclassing, and changing the layout of other elements inside the navigation bar, such as the title.

For example, to move a button 14 points to the left:

<pre><code>UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, image.size.width + 14, image.size.height)];
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(-14, 0, image.size.width, image.size.height);
[button setImage:image forState:UIControlStateNormal];
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
[containerView addSubview:button];

UIButton* button2 = [UIButton buttonWithType:UIButtonTypeCustom];
button2.frame = CGRectMake(0, 0, image.size.width + 14, image.size.height);
[button2 addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
[containerView addSubview:button2];

UIBarButtonItem* item = [[[self alloc] initWithCustomView:containerView] autorelease];
</code></pre>

 let suggestButton = UIButton(frame: CGRectMake(0, 0, 40, 40))

 // add the button to a container, otherwise the transform will be ignored 
 let suggestButtonContainer = UIView(frame: suggestButton.frame)

I needed to set my button to be more over towards the right. Here's how I did it using UIAppearance in Swift. There's a vertical position property there as well so I imagine you can adjust in any direction. 

<pre><code>UIBarButtonItem.appearance().setTitlePositionAdjustment(UIOffset.init(horizontal: 15, vertical: 0), forBarMetrics: UIBarMetrics.Default)

This seems much less invasive to me than messing with the frame directly or adding custom subviews.

You can always do adjustments using Insets on the button. For example,

[toggleBtn setFrame:CGRectMake(0, 0, 20, 20)];
[toggleBtn addTarget:self action:@selector(toggleView) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *toggleBtnItem = [[UIBarButtonItem alloc] initWithCustomView: toggleBtn];

If you're only looking for adjusting the position of the customized back button like me, I used one of the solutions that add insets to the UIImage itself to do achieve this.
I used the solution from: <a href="https://stackoverflow.com/a/31240900/1241783">https://stackoverflow.com/a/31240900/1241783</a>
Add this extension function
<pre><code>import UIKit

extension UIImage {
 func imageWithInsets(insets: UIEdgeInsets) -&gt; UIImage? {
 UIGraphicsBeginImageContextWithOptions(
 CGSize(width: self.size.width + insets.left + insets.right,
 height: self.size.height + insets.top + insets.bottom), false, self.scale)
 let _ = UIGraphicsGetCurrentContext()
 let origin = CGPoint(x: insets.left, y: insets.top)
 self.draw(at: origin)
 let imageWithInsets = UIGraphicsGetImageFromCurrentImageContext()
 UIGraphicsEndImageContext()
 return imageWithInsets
 }
}
</code></pre>
then use it like such when customizing the back button
<pre><code>let backIcon = UIImage(named: &quot;back_btn_icon&quot;)!.imageWithInsets(insets: UIEdgeInsets(top: 0, left: 0, bottom: 5, right: 0))
navigationController?.navigationBar.backIndicatorImage = backIcon
navigationController?.navigationBar.backIndicatorTransitionMaskImage = backIcon
</code></pre>
Adjust the insets as you desire
