iOS 开发应用内跳转到App Store_oc 跳转appstore指定应用

1.离开本应用跳转到App Store

 
NSString *url = @"https://itunes.apple.com/app/apple-store/id1457293407?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];

2.不离开本应用，应用内跳转到App Store

导入头文件 #import <StoreKit/StoreKit.h>

遵循代理协议 SKStoreProductViewControllerDelegate

- (void)jumpAppStore {
 
	NSDictionary *dict = [NSDictionary dictionaryWithObject:@"1457293407" forKey:SKStoreProductParameterITunesItemIdentifier];
	SKStoreProductViewController *vc = [[SKStoreProductViewController alloc] init];
	vc.delegate = self;
//	1.先加载，加载成功再跳转到App Store
	[vc loadProductWithParameters:dict completionBlock:^(BOOL result, NSError * _Nullable error) {
		if(error) {
			NSLog(@"Error：%@",error.userInfo);
		}
		else {
			[self presentViewController:vc animated:YES completion:nil];
		}
	}];
		//	2.先跳转到App Store，再加载数据
//	[self presentViewController:vc animated:YES completion:nil];
//	[vc loadProductWithParameters:dict completionBlock:^(BOOL result, NSError * _Nullable error) {
//		if(error) {
//			NSLog(@"Error：%@",error.userInfo);
//		}else {
//		}
//	}];
}
