iOS10.3新增了更換備用icon的API

// Pass `nil` to use the primary application icon. The completion handler will be invoked asynchronously on an arbitrary background queue; be sure to dispatch back to the main queue before doing any further UI work.
- (void)setAlternateIconName:(nullable NSString *)alternateIconName completionHandler:(nullable void (^)(NSError *_Nullable error))completionHandler NS_EXTENSION_UNAVAILABLE("Extensions may not have alternate icons") API_AVAILABLE(ios(10.3), tvos(10.2));

實(shí)現(xiàn)步驟

• 配置Info.plist文件
  因?yàn)橐獙?shí)現(xiàn)輪換icon,所以需要準(zhǔn)備兩個(gè)icon圖片,icon、icon2均為圖片名稱

<key>CFBundleIcons</key>
    <dict>
        <key>CFBundleAlternateIcons</key>
        <dict>
            <key>icon</key>
            <dict>
                <key>CFBundleIconFiles</key>
                <array>
                    <string>icon</string>
                </array>
            </dict>
            <key>icon2</key>
            <dict>
                <key>CFBundleIconFiles</key>
                <array>
                    <string>icon2</string>
                </array>
            </dict>
        </dict>
    </dict>

if ([[UIApplication sharedApplication].alternateIconName isEqualToString:@"icon2"]) {
    [[UIApplication sharedApplication] setAlternateIconName:@"icon" completionHandler:^(NSError * _Nullable error) {

同樣,iOS10.3也更新了AppStore評分系統(tǒng)API

/** Controller class to request a review from the current user */
SK_EXTERN_CLASS_AVAILABLE(10_3) __TVOS_UNAVAILABLE @interface SKStoreReviewController : NSObject

/** Request StoreKit to ask the user for an app review. This may or may not show any UI.
 *
 *  Given this may not succussfully present an alert to the user, it is not appropriate for use
 *  from a button or any other user action. For presenting a write review form, a deep link is 
 *  available to the App Store by appending the query params "action=write-review" to a product URL.
 */
+ (void)requestReview;
