如何在 Xcode 中为 Mac 应用程序设置图标？

How can I set the icon for a Mac Application in Xcode?

提问by kmikael

I have been learning a lot about writing Objective-C code and designing in Interface Builder and I wanted to set icons for my simple programs.

我已经学习了很多关于在 Interface Builder 中编写 Objective-C 代码和设计的知识，我想为我的简单程序设置图标。

I added the same JPG to all the size fields in Icon Composer and got an ICNS, but I couldn't figure out how to add it to the project.

我在 Icon Composer 中的所有大小字段中添加了相同的 JPG 并获得了一个 ICNS，但我不知道如何将它添加到项目中。

Thank you in advance.

先感谢您。

Since Xcode 4.4 Icon Composer is no longer the recommended way to create icons and is no longer included in the standard install of Xcode. Due to the introduction of Macs with retina display, it is now recommended to provide high resolution versions of all graphics including app icons.

由于 Xcode 4.4 Icon Composer 不再是创建图标的推荐方式，并且不再包含在 Xcode 的标准安装中。由于引入了带有视网膜显示的 Mac，现在建议提供所有图形的高分辨率版本，包括应用程序图标。

To give your app an icon under Xcode > 4.4 do the following:

要在 Xcode > 4.4 下为您的应用程序提供一个图标，请执行以下操作：

1. Create a folder [IconName].iconset in Finder

2. In this folder place your icon as png files. You'll need the icon in sizes of 16px, 32px, 64px (retina only), 128px, 256px, 512px and 1024px (retina only)

3. These icons must be named with the pattern icon_16x16.png, icon_32x32.png, icon_128x128.png and so on

4. To support retina displays you must also add icon files with double resolution, named [email protected] (with size 32x32), [email protected] (size 64x64) and so on up to [email protected] (size 1024x1024).

5. drag this [IconName].iconset folder to Xcode (copy if necessary)

6. in the info.plist file set the "CFBundleIconFile" (Icon File as Key) value to [IconName] but without the .iconset extension

1. 在 Finder 中创建文件夹 [IconName].iconset

2. 在此文件夹中，将您的图标放置为 png 文件。您需要大小为 16 像素、32 像素、64 像素（仅限视网膜）、128 像素、256 像素、512 像素和 1024 像素（仅限视网膜）的图标

3. 这些图标必须以 icon_16x16.png、icon_32x32.png、icon_128x128.png 等模式命名

4. 要支持视网膜显示，您还必须添加双分辨率的图标文件，命名为 [email protected]（大小为 32x32）、[email protected]（大小为 64x64）等等，直到 [email protected]（大小为 1024x1024）。

5. 将此 [IconName].iconset 文件夹拖到 Xcode（如有必要，请复制）

6. 在 info.plist 文件中将“CFBundleIconFile”（图标文件作为键）值设置为 [IconName] 但没有 .iconset 扩展名

Annotations:

注释：

• it is (currently) not required to provide the @2x icons
• it will (usually) also work if you don't provide every icon file
• the iconset folder should not contain a icon_64x64.png file. the 64px icon is only for the retina version of the icon_32x32

• （当前）不需要提供@2x 图标
• 如果您不提供每个图标文件，它（通常）也会起作用
• iconset 文件夹不应包含 icon_64x64.png 文件。64px 图标仅适用于 icon_32x32 的视网膜版本

Update:In the end your .iconset folder has the following 10 items:

更新：最后你的 .iconset 文件夹有以下 10 个项目：

icon_16x16.png
[email protected]
icon_32x32.png
[email protected]
icon_128x128.png
[email protected]
icon_256x256.png
[email protected]
icon_512x512.png
[email protected]

附加信息：

To convert the iconset folder to an icns file, run the following command on the terminal:

要将 iconset 文件夹转换为 icns 文件，请在终端上运行以下命令：

iconutil -c icns [IconName].iconset

where [IconName] should be replaced with the prefix of the iconset folder. You now have a file called [IconName].icns. In Xcode 4.4, in the Target Summary, right click the question mark for the icon, then select the icns file. You should then see the question mark get replaced with the icon.

其中 [IconName] 应替换为图标集文件夹的前缀。您现在有一个名为 [IconName].icns 的文件。在 Xcode 4.4 中，在 Target Summary 中，右键单击图标的问号，然后选择 icns 文件。然后您应该会看到问号被替换为图标。

As of Xcode 7 (not sure when this was originally introduced), you can use the Assets.xcassetsfile for app icons. This file is included by default for new projects.

从 Xcode 7（不确定最初何时引入）开始，您可以将Assets.xcassets文件用于应用程序图标。新项目默认包含此文件。

Simply:

简单地：

1. Go to your target's settings and ensure that under General, App Iconsthe Sourceis set to AppIcon.
2. Add all 10 png icons to your Assets.xcassets's AppIcon image.
3. Delete derived dataif you have launched the app before, otherwise it will continue to show the default icon.
4. Run the app; it should now show your icon in the Dock, Application Switcher, and anywhere else it should appear.

1. 转到目标的设置并确保在General、App Icons 下将Source设置为AppIcon。
2. 将所有 10 个 png 图标添加到 Assets.xcassets 的 AppIcon 图像中。
3. 如果您之前启动过该应用程序，请删除派生数据，否则它将继续显示默认图标。
4. 运行应用程序；它现在应该在 Dock、应用程序切换器和它应该出现的任何其他地方显示您的图标。

Step 1: Get iconfile name from info.plist and place icns(icon file) folder in SourceCode/resources folder

步骤 1：从 info.plist 获取 iconfile 名称并将 icns(icon file) 文件夹放在 SourceCode/resources 文件夹中

Step 2: And same thing goes for xcode,you have to copy all images from xcode using copyallframeworks or copyall resource file in your xcode and build the app again.

第 2 步：xcode 也是如此，您必须使用 xcode 中的 copyallframeworks 或 copyall 资源文件从 xcode 复制所有图像，然后再次构建应用程序。
