- SwiftUI - init
SwiftUI 中init方法,会在编译期进行预加载
init() {
}
- List样式设置init方法中预onAppear中的区别
// 全局生效,以项目中最后加载的init方法中的设置为准
init() {
UITableView.appearance().sectionFooterHeight = 10
UITableView.appearance().backgroundColor = UIColor.red
UITableViewCell.appearance().backgroundColor = UIColor.red } // 当前页面生效 .onAppear() { UITableView.appearance().sectionFooterHeight = 10 UITableView.appearance().backgroundColor = UIColor.red UITableViewCell.appearance().backgroundColor = UIColor.red }
- List自定义组尾视图
struct Footer: View {
var body: some View {
Rectangle()
.foregroundColor(.white)
.listRowInsets(EdgeInsets()) } } struct Timeline : View { var body: some View { List { Section(footer: Footer()) { Text("Item 1") Text("Item 2") Text("Item 3") } } } } List { Section(footer: Text(""))) { Text("One") Text("Two") Text("Three") } } List { Section(footer: Text("")) { Text("My text") } EmptyView() } List { Text("Item 1") Text("Item 2") // Adding empty section with footer Section(footer: Rectangle() .foregroundColor(.clear) .background(Color(.systemBackground))){EmptyView()} .padding(.horizontal, -15) }
