## 技术交付物
### iOS SwiftUI 组件示例
```swift
// 现代 SwiftUI 组件,带性能优化
import SwiftUI
import Combine
struct ProductListView: View {
@StateObject private var viewModel = ProductListViewModel()
@State private var searchText = ""
var body: some View {
NavigationView {
List(viewModel.filteredProducts) { product in
ProductRowView(product: product)
.onAppear {
// 滚动到最后一条时触发分页加载
if product == viewModel.filteredProducts.last {
viewModel.loadMoreProducts()
}
}
}
.searchable(text: $searchText)
.onChange(of: searchText) { _ in
viewModel.filterProducts(searchText)
}
.refreshable {
await viewModel.refreshProducts()
}
.navigationTitle("Products")
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Button("Filter") {
viewModel.showFilterSheet = true
}
}
}
.sheet(isPresented: $viewModel.showFilterSheet) {
FilterView(filters: $viewModel.filters)
}
}
.task {
await viewModel.loadInitialProducts()
}
}
}
// MVVM 模式实现
@MainActor
class ProductListViewModel: ObservableObject {
@Published var products: [Product] = []
@Published var filteredProducts: [Product] = []
@Published var isLoading = false
@Published var showFilterSheet = false
@Published var filters = ProductFilters()
private let productService = ProductService()
private var cancellables = Set<AnyCancellable>()
func loadInitialProducts() async {
isLoading = true
defer { isLoading = false }
do {
products = try await productService.fetchProducts()
filteredProducts = products
} catch {
// 错误处理,给用户友好提示
print("Error loading products: \\(error)")
}
}
func filterProducts(_ searchText: String) {
if searchText.isEmpty {
filteredProducts = products
} else {
filteredProducts = products.filter { product in
product.name.localizedCaseInsensitiveContains(searchText)
}
}
}
}
```
### Android Jetpack Compose 组件示例
```kotlin
// 现代 Jetpack Compose 组件,带状态管理
@Composable
fun ProductListScreen(
viewModel: ProductListViewModel = hiltViewModel()
) {
val uiState by viewModel.uiState.collectAsStateWithLifecycle()
val searchQuery by viewModel.searchQuery.collectAsStateWithLifecycle()
Column {
SearchBar(
query = searchQuery,
onQueryChange = viewModel::updateSearchQuery,
onSearch = viewModel::search,
modifier = Modifier.fillMaxWidth()
)
LazyColumn(
modifier = Modifier.fillMaxSize(),
contentPadding = PaddingValues(16.dp),
verticalArrangement = Arrangement.spacedBy(8.dp)
) {
items(
items = uiState.products,
key = { it.id }
) { product ->
ProductCard(
product = product,
onClick = { viewModel.selectProduct(product) },
modifier = Modifier
.fillMaxWidth()
.animateItemPlacement()
)
}
if (uiState.isLoading) {
item {
Box(
modifier = Modifier.fillMaxWidth(),
contentAlignment = Alignment.Center
) {
CircularProgressIndicator()
}
}
}
}
}
}
// ViewModel带生命周期管理
@HiltViewModel
class ProductListViewModel @Inject constructor(
private val productRepository: ProductRepository
) : ViewModel() {
private val _uiState = MutableStateFlow(ProductListUiState())
val uiState: StateFlow<ProductListUiState> = _uiState.asStateFlow()
private val _searchQuery = MutableStateFlow("")
val searchQuery: StateFlow<String> = _searchQuery.asStateFlow()
init {
loadProducts()
observeSearchQuery()
}
private fun loadProducts() {
viewModelScope.launch {
_uiState.update { it.copy(isLoading = true) }
try {
val products = productRepository.getProducts()
_uiState.update {
it.copy(
products = products,
isLoading = false
)
}
} catch (exception: Exception) {
_uiState.update {
it.copy(
isLoading = false,
errorMessage = exception.message
)
}
}
}
}
fun updateSearchQuery(query: String) {
_searchQuery.value = query
}
// 监听搜索输入300ms 防抖
private fun observeSearchQuery() {
searchQuery
.debounce(300)
.onEach { query ->
filterProducts(query)
}
.launchIn(viewModelScope)
}
}
```
### 跨平台 React Native 组件示例

// React Native 组件,带平台特定优化
import React, { useMemo, useCallback } from 'react';
import {
FlatList,
StyleSheet,
Platform,
RefreshControl,
} from 'react-native';
import { useSafeAreaInsets } from 'react-native-safe-area-context';
import { useInfiniteQuery } from '@tanstack/react-query';
interface ProductListProps {
onProductSelect: (product: Product) => void;
}
export const ProductList: React.FC<ProductListProps> = ({ onProductSelect }) => {
const insets = useSafeAreaInsets();
const {
data,
fetchNextPage,
hasNextPage,
isLoading,
isFetchingNextPage,
refetch,
isRefetching,
} = useInfiniteQuery({
queryKey: ['products'],
queryFn: ({ pageParam = 0 }) => fetchProducts(pageParam),
getNextPageParam: (lastPage, pages) => lastPage.nextPage,
});
// 扁平化分页数据
const products = useMemo(
() => data?.pages.flatMap(page => page.products) ?? [],
[data]
);
const renderItem = useCallback(({ item }: { item: Product }) => (
<ProductCard
product={item}
onPress={() => onProductSelect(item)}
style={styles.productCard}
/>
), [onProductSelect]);
// 滚动到底部时加载下一页
const handleEndReached = useCallback(() => {
if (hasNextPage && !isFetchingNextPage) {
fetchNextPage();
}
}, [hasNextPage, isFetchingNextPage, fetchNextPage]);
const keyExtractor = useCallback((item: Product) => item.id, []);
return (
<FlatList
data={products}
renderItem={renderItem}
keyExtractor={keyExtractor}
onEndReached={handleEndReached}
onEndReachedThreshold={0.5}
refreshControl={
<RefreshControl
refreshing={isRefetching}
onRefresh={refetch}
colors={['#007AFF']} // iOS 风格颜色
tintColor="#007AFF"
/>
}
contentContainerStyle={[
styles.container,
{ paddingBottom: insets.bottom }
]}
showsVerticalScrollIndicator={false}
removeClippedSubviews={Platform.OS === 'android'}
maxToRenderPerBatch={10}
updateCellsBatchingPeriod={50}
windowSize={21}
/>
);
};
const styles = StyleSheet.create({
container: {
padding: 16,
},
productCard: {
marginBottom: 12,
//
...Platform.select({
ios: {
shadowColor: '#000',
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.1,
shadowRadius: 4,
},
android: {
elevation: 3,
},
}),
},
});
