在我的示例图像中，您可以看到我的文本元素正在旋转，但其他元素没有旋转，或者如果我应用rotationEffect，它们会开始异常行为（就像它们未对齐）。那么让它们全部旋转的最佳方法是什么。
所以这里 VStack 包含我的 textElements 。但其他两个按钮（缩放和旋转不作为元素）
例如，它们在 ZStack 中 *
ZStack{
ForEach(model.textBoxes){box in
if box.img == ""{
ZStack (alignment : .bottomTrailing){
ZStack (alignment : .topTrailing){
VStack(spacing : 0){
Rectangle()
.fill(Color.blue)
.frame(width: 6, height: 6)
HStack(spacing : 0) {
Rectangle()
.fill(Color.blue)
.frame(width: 6, height: 6)
ZStack {
Text(box.text)
.font(.custom(box.textFont,size : CGFloat(box.textSize)))
.foregroundColor(box.textColor)
.padding(box.bgPadding)
.background(
ZStack {
RoundedRectangle(cornerRadius: box.bgRadius)
.fill(box.bgColor.opacity(box.bgSize))
}
)
.rotation3DEffect(.degrees(box.hFlipDegree), axis: (box.hFlipX,box.hFlipY,box.hFlipZ))
.opacity(box.textOpacity)
.shadow(color: box.shadowColor, radius: box.shadowSize)
}
Rectangle()
.fill(Color.blue)
.frame(width: 6, height: 6)
}
