iOS 從應用程序跳轉到評價界面

1，跳轉到App Store：
NSString *str = [NSString stringWithFormat:@"http://itunes.apple.com/us/app/id%d", 1001065082];
[[UIApplication sharedApplication] openURL:[NSURL urlWithString:str]];

1001065082是App ID

2,跳轉到評價頁面:
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]];
