ios - 如何将按钮设置到导航的最右侧 - iOS
<p><p>我在导航栏右侧设置了一个按钮:</p>
<p>我的 ViewController :
<a href="/image/52Y30.png" rel="noreferrer noopener nofollow"><img src="/image/52Y30.png" alt="enter image description here"/></a> </p>
<p>我想为这个按钮设置一个汉堡图标、红色循环和一个标签。像这样:</p>
<p> <a href="/image/dSJ8s.png" rel="noreferrer noopener nofollow"><img src="/image/dSJ8s.png" alt="enter image description here"/></a> </p>
<p>我的代码:</p>
<pre><code> self.navigationController?.navigationBar.barTintColor = self.utilities.hexStringToUIColor(hex: "#00b8de")
var imageview2 = UIImage(named: "menulogo")
imageview2 = imageview2?.imageResize(sizeChange: CGSize(width: 25, height: 25))
btnMenu.setImage(imageview2,for:UIControlState.normal)
btnMenu.setTitle("", for: .normal)
// setup the red circle UIView
let redCircleView = UIView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
redCircleView.backgroundColor = UIColor.red
redCircleView.layer.cornerRadius = view.frame.size.width / 2
// setup the number UILabel
let label = UILabel(frame: CGRect(x: 30, y: 0, width: 20, height: 20))
label.textColor = UIColor.white
label.font = UIFont.systemFont(ofSize: 10)
label.text = "16"
// adding the label into the red circle
redCircleView.addSubview(label)
// adding the red circle into the menu button
btnMenu.addSubview(redCircleView)
</code></pre>
<p>使用上面的代码我有三个问题:</p>
<ol>
<li>我的汉堡图片不在导航的最右侧。</li>
<li>我的自行车 View 没有显示</li>
<li>我的图标是白色的,但它显示为蓝色!</li>
</ol>
<p><code>btnMenu</code> 是我的导航按钮。</p>
