iOS版本更新在APP中直接访问AppStore

1.导入框架 #import <StoreKit/StoreKit.h>

2.添加代理 <SKStoreProductViewControllerDelegate>

3.设置跳转控制器

SKStoreProductViewController *storeVC = [[SKStoreProductViewController alloc]init];

storeVC.delegate = self;

NSDictionary *params = @{SKStoreProductParameterITunesItemIdentifier:identifier};

[storeVC loadProductWithParameters:params completionBlock:^(BOOL result, NSError * _Nullable error) {

if (result) {

[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:storeVC animated:YES completion:^{

NSLog(@"present");

}];

}

}];

4.实现代理方法

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

[[UIApplication sharedApplication].keyWindow.rootViewController dismissViewControllerAnimated:YES completion:^{

NSLog(@"dismiss");

}];

}
