如何为多个图片扩展注册iOS应用？

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Open iniOS菜单中的.jpeg扩展名.如何让它适用于其他两个扩展？

<key>CFBundleDocumentTypes</key>
<array>

你只想要一个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>

而不是手动编辑Info.plist,将这些详细信息输入Xcode.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.
