推荐答案

是的，iOS 10.3终于为开发人员提供了这种能力以编程方式更改其应用的图标。

Yes, iOS 10.3 finally gives developers the ability to change their app’s icon programmatically.

可以从iOS 10.3更改appIcon。为此，您需要在 info.plist supportsAlternateIcon 设置为是 C>。

It is possible to change appIcon from iOS 10.3. For that you need to set supportsAlternateIcon to Yes in info.plist.

主要和辅助图标都应添加到应用信息的 CFBundleIcons 键中。 plist file。

Both primary and secondary icons should be added in CFBundleIcons key of your app's Info.plist file.

//Info.plist
<key>CFBundleIcons</key>
<dict>
    <key>CFBundleAlternateIcons</key>
    <dict>
        <key>Icon1</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>alternater1</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
        <key>Icon2</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>alternater2</string>
            </array>
        </dict>
    </dict>
</dict>

要在UIApplication方法之后更改App Icon，需要调用：

To change App Icon following UIApplication method needs to be called:

目标C：

[[UIApplication sharedApplication] setAlternateIconName:@"alternater2" completionHandler:^(NSError * _Nullable error) {
        NSLog(@"Error...");
}];

Swift 3：

if UIApplication.shared.supportsAlternateIcons{
        UIApplication.shared.setAlternateIconName("alternater2", completionHandler: { (error) in
            print(error ?? "")
        })
}
