IOS 15 UIButton 右对齐不起作用
IOS 15 UIButton right alignment not working
问：
在 IOS 15 中，即使将按钮文本向右对齐后，它也会在按钮标题文本后留下很少的空间。 如下图所示，它保留了单词 Test 后面的空格。 如何删除此空间？我希望文本中的字母“t”触摸按钮的尾部。
在 ios 14 及更低版本中，它看起来像这样

您可以尝试将其与 DispatchQueue 一起使用
button.contentHorizontalAlignment = .left
emailBtn.contentEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)

这是一个小技巧，或者你可以用UIButton.Configuration来做到这一点，像这样设置你的按钮：
let myButton: UIButton = {
let b = UIButton()
b.backgroundColor = .white
b.tintColor = .black
b.layer.cornerRadius = 8
b.clipsToBounds = true
b.setTitle(" My button Test", for: .normal) // space in front of string = space fron text and image
b.setTitleColor(.black, for: .normal)
b.titleLabel?.font = .systemFont(ofSize: 17, weight: .regular)
b.contentHorizontalAlignment = .right
b.setImage(UIImage(systemName: "bag"), for: .normal)
b.configuration?.imagePlacement = .leading // use button configuration to add image position
b.translatesAutoresizingMaskIntoConstraints = false
return b
}()
这是 UIButton.Configuration 样式：
let myButton: UIButton = {
var filled = UIButton.Configuration.filled()
filled.title = "My button Test"
filled.buttonSize = .large
filled.baseBackgroundColor = .white
filled.baseForegroundColor = .black
filled.cornerStyle = .medium
filled.image = UIImage(systemName: "bag", withConfiguration: UIImage.SymbolConfiguration(scale: .large))
filled.imagePlacement = .leading
filled.imagePadding = 4
filled.contentInsets = NSDirectionalEdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0)
let b = UIButton(configuration: filled, primaryAction: nil)
b.contentHorizontalAlignment = .right
b.translatesAutoresizingMaskIntoConstraints = false
return b
}()
在 viewDidLoad 中显示按钮并设置约束：
view.addSubview(myButton)
myButton.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myButton.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
myButton.heightAnchor.constraint(equalToConstant: 50).isActive = true
myButton.widthAnchor.constraint(equalToConstant: 200).isActive = true
结果如下：

尝试同时设置：
button.titleEdgeInsets = UIEdgeInsets(top: 0, left: 25, bottom: 0, right: 00)
button.imageEdgeInsets = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 00)
