iOS 10.3 增加了两个开发者比较关心的特性：

1. 更换app icon
2. 应用内评论

更换app icon

1 . 在info.plist中添加两个字段 CFBundleAlternateIcons 和 CFBundlePrimaryIcon

注意：根据我的测试，CFBundlePrimaryIcon是必须的，否则一直显示默认icon。

<key>CFBundleIcons</key>
<dict>
    <key>CFBundleAlternateIcons</key>
    <dict>
        <key>AppIcon2</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>AppIcon2</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
    </dict>
    <key>CFBundlePrimaryIcon</key>
    <dict>
        <key>CFBundleIconFiles</key>
        <array>
            <string>AppIcon60x60</string>
        </array>
    </dict>
</dict>

2 . 添加 AppIcon2@2x.png AppIcon2@3x.png 到项目中(不能添加到Assets.xcassets)

根据我的测试，添加到Assets.xcassets不生效

3 . 添加代码

if ([app supportsAlternateIcons]) {
        [app setAlternateIconName:@"AppIcon2" completionHandler:^(NSError * _Nullable error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                [self updateLabel];
            });
        }];
}

应用内评论

#import <StoreKit/StoreKit.h>
if ([UIDevice currentDevice].systemVersion.floatValue >= 10.3) {
    [SKStoreReviewController requestReview];
}
