要实现动态排序，您需要将@Query属性移至 SwiftUI 层次结构中的视图中 - 您需要将其放入子视图中，在其中可以使用依赖项注入提供排序值。 这意味着创建一个新的 SwiftUI，它使用@Query来显示您...

当指定的值发生变化时，将给定的动画应用于此视图。 struct ContentView: View { @State private var scale = 0.5 var body: some View { VStack { Circle().scale(scale).animation(.easeIn, v...

使用提供的动画重新计算视图主体，并返回结果。 struct ContentView: View { @State private var isActive = false var body: some View { VStack(alignment: isActive ? .trailing : .leading)...

一个容器，通过自动循环遍历你提供的一系列阶段来对其内容进行动画处理，每个阶段定义了动画中的一个离散步骤。 具有阶段动画的弹跳 例如，前面展示的表情符号弹跳动画具有两个阶段：向上移动和...

当前状态处理更新的上下文。 transaction(value:_:) 使用.transaction 修饰符来更改或替换视图中使用的动画。考虑一个由按钮控制的三个相同视图，同时改变所有三个的情况： 第一个视图通过旋转...

Using async functions in Swift is done in two steps: declaring the function itself as being async, then calling that function using await.在 Swift 中使用异步函数分两步完...

Just like their synchronous counterparts, Swift’s async functions can be throwing or non-throwing depending on how you want them to behave. However, there is a twist: although we ...

You can only call async functions from other async functions, because they might need to suspend themselves and everything that is waiting for them. This leads to a bit of a chicke...
