iOS 应用中直接跳转到 AppStore 的方法

找到应用程序的描述链接，比如：https://itunes.apple.com/gb/app/yi-dong-cai-bian/id391945719?mt=8

然后将 https:// 替换为 itms:// 或者 itms-apps://：

 itms://itunes.apple.com/gb/app/yi-dong-cai-bian/id391945719?mt=8
 itms-apps:// itunes.apple.com/gb/app/yi-dong-cai-bian/id391945719?mt=8  

然后打开这个链接地址：

[[uiapplication sharedapplication] openurl:[nsurl urlwithstring:@"itms://itunes.apple.com/gb/app/yi-dong-cai-bian/id391945719?mt=8"]];

[[uiapplication sharedapplication] openurl:[nsurl urlwithstring:@"itms-apps ://itunes.apple.com/gb/app/yi-dong-cai-bian/id391945719?mt=8"]];

跳转到应用评价页
nsstring *urlstr = [nsstring stringwithformat:@"itms-apps://itunes.apple.com/webobjects/mzstore.woa/wa/viewcontentsuserreviews?type=purple+software&id=%@&pagenumber=0&sortordering=2&mt=8", appid];
[[uiapplication sharedapplication] openurl:[nsurl urlwithstring:urlstr]];

跳转到应用详情页
nsstring *urlstr = [nsstring stringwithformat:@"itms-apps://itunes.apple.com/app/id%@", appid];
[[uiapplication sharedapplication] openurl:[nsurl urlwithstring:urlstr]];

这个最好在真机上面测试，在模拟器上测试，会没有效果。
