方法一:

[[UIApplicationsharedApplication] openURL:[NSURLURLWithString:@"https://itunes.apple.com/cn/app/xxxx"]];

方法二:(推薦)

添加StoreKit,framework系統(tǒng)庫，實(shí)現(xiàn)相應(yīng)的代理方法

SKStoreProductViewController*store = [[SKStoreProductViewControlleralloc] init];

store.delegate =self;

[store loadProductWithParameters://appId唯一的

@{SKStoreProductParameterITunesItemIdentifier:@"appid"} completionBlock:^(BOOL ?result,NSError*error) {

} }]

//取消代理

- (void)productViewControllerDidFinish:(SKStoreProductViewController*)viewController{? ??

];}
