iOS App 跳转到 AppStore

iOS设备上的App经常需要跳转到AppStore中进行升级或者是评价，这个过程其实很简单：给一个需要跳转的App对应的URL，然后调用跳转的方法openURL:不过这个URL地址老是忘记，还是记下了比较好。

直接跳转

其实这个问题很简单，首先拿到你要跳转到的AppStore地址（URL）例如：
https://itunes.apple.com/cn/app/jie-zou-da-shi/id493901993?mt=8

然后将 http:// 替换为 itms-apps://
然后调用以下代码

        NSString *str = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/cn/app/jie-zou-da-shi/id493901993?mt=8"];        NSURL * url = [NSURL URLWithString:str];        if ([[UIApplication sharedApplication] canOpenURL:url])        {            [[UIApplication sharedApplication] openURL:url];        }        else        {            NSLog(@"can not open");        }

跳转到评论区

代码如下：

        //去评分        NSString *str = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=%@",@"1006631751"];        NSURL * url = [NSURL URLWithString:str];        if ([[UIApplication sharedApplication] canOpenURL:url])        {            [[UIApplication sharedApplication] openURL:url];        }        else        {            NSLog(@"can not open");        }
