对于iPhone 5.5”显示器，你需要在iPhone 8 Plus上将模拟器更改为“物理大小”

另外，请注意，你可以设置透明度，即使你的图像实际上没有任何透明度。如果你用的是photoshop，选择“保存为网页格式”，取消选择“透明”，或者直接将图片转换成jpg格式。iTunes Connect似乎也拒绝透明度。

在模拟器上运行应用程序，并保存屏幕截图。 将这些截图重命名为4.7.1 (iPhone 6)， 5.5.1 (iPhone 6 plus)等等。

我把这个页面收藏起来，经常回头看，但没有人提到更新的11英寸iPad pro的尺寸。1668 x2388。

下面是一个bash脚本，它将通用屏幕截图调整为适当的尺寸。到2020年，我还不能让iPhone 4模拟器在最新的xcode中运行，所以这对我来说是必要的。

#!/usr/bin/env bash

HERE="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"

declare -A sizes
sizes["6-5-inch-iphone-xs-max"]="1242x2688"

for i in "${!sizes[@]}"; do
    if [[ "$i" == *"ipad"* ]]; then
        [ -d "$HERE/ipad" ] || continue
        mkdir -p "$HERE/$i"
        cd "$HERE/ipad"
        for file in *.jpg; do
            [ -e "$file" ] || continue
            convert "$file" -resize "${sizes[$i]}"\! "$HERE/$i/$file"
            echo "scaled $file"
        done
    else
        [ -d "$HERE/iphone" ] || continue
        mkdir -p "$HERE/$i"
        cd "$HERE/iphone"
        for file in *.jpg; do
            [ -e "$file" ] || continue
            convert "$file" -resize "${sizes[$i]}"\! "$HERE/$i/$file"
            echo "scaled $file"
        done
    fi
done

要使用它，将它放在一个新目录中，并在它旁边创建一个/iphone和/ipad目录。把你的ipad和iphone截图放在这些文件夹里。运行该脚本，它将生成所有大小的命名文件夹。
