最佳实践

截图设计

• 安全区域：重要内容应远离边缘——避免将内容放在顶部 20% 的状态栏区域
• 文本层级：使用醒目、易读的标题（至少相当于 40 pt）
• 设备边框：使用当前一代设备模型（iPhone 15 Pro、Pixel 8）
• 对比度：确保文字在任何背景元素上都清晰可读
• 一致性：所有截图应保持相同的风格、字体和配色方案

App Store 优化

• 第一张截图：让它成为最出色的一张——用户通常只会看到这一张
• 功能说明：每张截图突出 1-2 项核心功能
• 本地化：为目标市场翻译所有文字，而不仅是标题
• 季节性更新：应用有重大更新时，及时更新截图

iPad 截图

• 横屏选项：部分应用可使用 iPad 横屏截图
• 利用空间：利用更大的画布展示更详细的 UI
• 分屏视图：如适用，展示多任务处理能力

模式选择

生成前询问用户：

“您想要便于迭代的快速草稿，还是可供提交的最终品质？”

模式	最适用于	速度	品质
max	提交至 App Store 的最终版本、精修素材	较慢	最高
eco	快速草稿、A/B 测试变体、概念探索	较快	良好

多轮截图迭代

使用 session_id 迭代截图设计：

# Initial screenshot
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create an iPhone App Store screenshot at 1320x2868 for a podcast app with episode list view"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "podcast-screenshot-v1"
  }'

# Iterate based on feedback
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Add a headline saying \"Your Daily Commute Companion\" and change the background to a gradient purple"}],

    "model": "eachsense/beta",
    "stream": true,
    "session_id": "podcast-screenshot-v1"
  }'

# Request variation
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create 2 more variations with different headline angles - one focusing on discovery, one on offline listening"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "podcast-screenshot-v1"
  }'

iPad 截图生成

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create an iPad App Store screenshot at 2064x2752 pixels for a design app. Show iPad Pro device frame with the canvas workspace, featuring drawing tools, layers panel, and color picker.

错误处理

错误	原因	解决方案
Failed to create prediction: HTTP 422	余额不足	在 eachlabs.ai 充值
内容策略违规	内容被禁止	调整提示词，使其符合应用商店指南
超时	生成过程复杂	将客户端超时设为至少 10 分钟
尺寸不匹配	宽高比错误	使用上表中的准确规格
