如何点击链接直接跳转到app store指定应用下载页面

转载自：http://blog.csdn.net/zengconggen/article/details/6789420

NSString *str = [NSString stringWithFormat:@"http://itunes.apple.com/us/app/id%d", 436957167];
[[UIApplication sharedApplication] openURL:[NSURL urlWithString:str]];

其中，436957167 是 app 的 id
附：跳转到某 app 的评价页面：

NSString *str = [NSString stringWithFormat:@"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=%d", 436957167];
[[UIApplication sharedApplication] openURL:[NSURL urlWithString:str]];
