如何为多个图像扩展注册iOS应用程序

Question

我想将我的iOS注册为.jpg（.jepg）、.png和.gif的编辑器。我尝试了下面的代码，但我的应用程序只显示在.jpeg扩展名的Open in iOS菜单中。如何使其适用于其他两个扩展？

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>public.jpeg</string>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>

您只需要一个CFBundleDocumentTypes部分：

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>public.jpeg</string>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>public.jpeg</string>
        </array>
    </dict>
    <dict>
        <key>CFBundleTypeName</key>
        <string>public.png</string>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>public.png</string>
        </array>
    </dict>
    <dict>
        <key>CFBundleTypeName</key>
        <string>GIF image</string>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.compuserve.gif</string>
        </array>
    </dict>
</array>

在Xcode中输入这些详细信息，而不是手动编辑Info.plist。让它为您更新Info.plist。在"文档类型"部分下的目标的"信息"选项卡上执行此操作。
