Swift 5中如何调整Google Maps上的Floaty按钮及设置内边距？

我是iOS开发新手，已经创建了Floaty按钮，但尝试设置内边距始终无法生效，请问该如何设置？

现有代码 #

Floaty.global.rtlMode = true
floaty.addItem("Start Navigation", icon: UIImage(named: "navigation-2 icon")!, handler: { item in
    let dialogMessage = UIAlertController(title: "Confirm Map Type", message: "Please select map Type for navigation", preferredStyle: .alert)
    // Create OK button with action handler
    let apple = UIAlertAction(title: "Apple Map", style: .default, handler: { (action) -> Void in
        print("Apple Map")
        self.openMapWithApple()
    })
    // Create Cancel button with action handlder
    let google = UIAlertAction(title: "Google Map", style: .cancel) { (action) -> Void in
        print("Google Map")
        self.openMapWithgoogle()
    }
    //Add OK and Cancel button to an Alert object
    dialogMessage.addAction(apple)
    dialogMessage.addAction(google)
    // Present alert message to user
    self.present(dialogMessage, animated: true, completion: nil)
    
    floaty.close()
})
self.view.addSubview(floaty)

解决方案 #

Floaty库提供了专门的属性来控制内边距，你可以在添加子项或把按钮添加到视图前设置这些属性：

1. 设置主悬浮按钮的内边距
   使用buttonInsets属性调整主按钮内部图标/内容的边距：

   // 示例：给主按钮设置8pt的内边距
   floaty.buttonInsets = UIEdgeInsets(top: 8, left: 8, bottom: 8, right: 8)
   

2. 设置展开后子项的内边距
   使用itemInsets属性调整每个展开子项的整体内边距：

   // 示例：给子项设置上下4pt、左右8pt的内边距
   floaty.itemInsets = UIEdgeInsets(top: 4, left: 8, bottom: 4, right: 8)
   

3. 调整子项标题与图标的间距
   如果需要单独调整子项内标题和图标的距离，可以使用itemTitlePadding：

   floaty.itemTitlePadding = 12 // 设置标题与图标之间的间距为12pt
   

修改后的完整代码示例 #

Floaty.global.rtlMode = true

// 设置内边距属性
floaty.buttonInsets = UIEdgeInsets(top: 8, left: 8, bottom: 8, right: 8)
floaty.itemInsets = UIEdgeInsets(top: 4, left: 8, bottom: 4, right: 8)
floaty.itemTitlePadding = 12

floaty.addItem("Start Navigation", icon: UIImage(named: "navigation-2 icon")!, handler: { item in
    let dialogMessage = UIAlertController(title: "Confirm Map Type", message: "Please select map Type for navigation", preferredStyle: .alert)
    let apple = UIAlertAction(title: "Apple Map", style: .default, handler: { (action) -> Void in
        print("Apple Map")
        self.openMapWithApple()
    })
    let google = UIAlertAction(title: "Google Map", style: .cancel) { (action) -> Void in
        print("Google Map")
        self.openMapWithgoogle()
    }
    dialogMessage.addAction(apple)
    dialogMessage.addAction(google)
    self.present(dialogMessage, animated: true, completion: nil)
    
    floaty.close()
})
self.view.addSubview(floaty)
