Dummy class easing detection whether the native StoreKit in-app Review alert has been fired or not. Useful as a callback when firing the limited system rating alert.

SKStoreReviewDummyClass.m

@interface SKStoreReviewDummyClass : NSObject @end

@implementation SKStoreReviewDummyClass

+ (void)load
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{

        Class class = [self class];
        Class ratingClass = NSClassFromString(@"SKStoreReviewPresentationWindow");

        SEL originalSelector = @selector(init);
        SEL swizzledSelector = @selector(xxx_init);

        Method oldMethod = class_getInstanceMethod(ratingClass, originalSelector);
        Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);

        class_addMethod(ratingClass,
                        swizzledSelector,
                        method_getImplementation(swizzledMethod),
                        method_getTypeEncoding(swizzledMethod));

        swizzledMethod = class_getInstanceMethod(ratingClass, swizzledSelector);
        method_exchangeImplementations(oldMethod, swizzledMethod);

    });
}

- (instancetype)xxx_init
{
    NSLog(@"Star rating alert fired !!!!");
    return [self xxx_init];
}

@end

Has Apple approved this usage in your app? Any risk of app rejection?

Same question here. Did Apple approve that?
