Show App Store app page in app - ios

Question

There are some apps (like the free version of Cut the Rope) that present the App Store page of other apps directly in the app (probably using a modal view controller).
How do I implement this in my own app?
Example from Cut the Rope:

Answer 1

You can use SKStoreProductViewController for this, check out documentation for more detail
if ([SKStoreProductViewController class]) {
NSString *yourAppID = #"";//Give your app id here
NSDictionary *appParameters = #{SKStoreProductParameterITunesItemIdentifier :yourAppID};
SKStoreProductViewController *productViewController = [[SKStoreProductViewController alloc] init];
[productViewController setDelegate:self];
[productViewController loadProductWithParameters:appParameters completionBlock:nil];
[self presentViewController:productViewController animated:YES completion:nil];
}

Answer 2

One can implement a App Store page of any application within their own app by using the SKStoreProductViewController class.
NSString *strURL = #"" //Keep the App store URL here.
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 6.0)
{
SKStoreProductViewController *storeProductViewController = [[SKStoreProductViewController alloc] init];
NSRange range = [strURL rangeOfString:#"/id"];
NSRange rangeID = {range.location + 3, 9};
NSString *strAppID = [strURL substringWithRange:rangeID];
NSLog(#"appid = %#", strAppID);
// Configure View Controller
[storeProductViewController setDelegate:self];
[storeProductViewController loadProductWithParameters:#{SKStoreProductParameterITunesItemIdentifier : strAppID}
completionBlock:^(BOOL result, NSError *error) {
if (error) {
NSLog(#"Error %# with User Info %#.", error, [error userInfo]);
} else {
}
}];
// Present Store Product View Controller
[self presentViewController:storeProductViewController animated:YES completion:nil];
}
The above code also extracts the app ID from the URL.
You can read about it in the class reference.
