MacAPP指令碼

概述

之前用的一個批量匯出APP圖示和啟動圖的軟體，今天發現收費了，於是自己造了個簡單的輪子。

實現

Mac上的sips命令，可以很方便的幫助使用者修改圖片尺寸

Xcode裡面的APP啟動圖資源包含兩部分

  1. 圖片資源
  2. 描述檔案

所以這個指令碼的功能就是兩個

  1. 生成描述檔案Contents.json
  2. 修改圖片尺寸並關聯描述檔案

生成描述檔案

使用echo簡單粗暴的寫入

setContents(){
echo {  >> ./AppIcon/Contents.json
echo "  "images"" : [>> ./AppIcon/Contents.json
echo "   "{>> ./AppIcon/Contents.json
echo "      "size"" : ""20x20"",>> ./AppIcon/Contents.json
echo "      "idiom"" : ""iphone"",>> ./AppIcon/Contents.json
echo "      "scale"" : ""2x"",>> ./AppIcon/Contents.json
echo "      "filename"" : ""icon_40x40.png"">> ./AppIcon/Contents.json
echo "   "},>> ./AppIcon/Contents.json
echo "   "{>> ./AppIcon/Contents.json
echo "      "size"" : ""20x20"",>> ./AppIcon/Contents.json
echo "      "idiom"" : ""iphone"",>> ./AppIcon/Contents.json
echo "      "scale"" : ""3x"",>> ./AppIcon/Contents.json
echo "      "filename"" : ""icon_60x60.png"">> ./AppIcon/Contents.json
echo "   "},>> ./AppIcon/Contents.json
echo "   "{>> ./AppIcon/Contents.json
echo "      "size"" : ""29x29"",>> ./AppIcon/Contents.json

echo }>> ./AppIcon/Contents.json
}

修改圖片尺寸

iconWithSize() {
sips -Z $1 icon.png --out ./AppIcon/icon_$1x$1.png
}

函式呼叫

mkdir AppIcon
setContents
for size in  40 58 60 80 87 120 180 1024
do
iconWithSize $size
done

效果展示

怎麼使用

AppIcon

下載對應的sh檔案，放到你想匯出圖片的目錄下，將你的原圖命名為icon.png，然後在控制檯中進入該目錄，執行

sh AppIcon.sh

LaunchImage

下載對應的sh檔案，放到你想匯出圖片的目錄下，將你的原圖命名為Default.png，然後在控制檯中進入該目錄，執行

sh AppLaunch.sh

就可以得到你要的資源啦。

擴充套件

在命令列使用sips命令修改圖片尺寸

重新定義單個圖片尺寸（忽略比例）

sips -z 768 1024 xxx.png

修改後圖片尺寸為1024x768

重新定義單個圖片尺寸（保留比例）

sips -Z 500 xxx.png

==保留圖片比例，寬高不超過500。注意是大寫的Z==。要想保留圖片原始比例就得這樣做，比如你有一張尺寸為750 x 1334的圖片，執行完上面這條命令後，圖片尺寸就變成了281x500

在一個目錄裡批量修改同一字尾格式的圖片尺寸

sips -Z 300 *.png

只需要用*作為萬用字元來代替圖片名就可以了
