在ios6.0前跳转到appstore评分一般是调用Application直接跳转到appstore评分
NSString *evaluateString = [NSString stringWithFormat:@'itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=587767923'];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:evaluateString]];
在ios6.0，APPle增加了一个心得功能，当用户需要给APP评分时候，不再跳转到appstore了，可以在应用内实现打开appstore，苹果提供了一个框架StoreKit.framework,实现步骤如下:
1:导入StoreKit.framework,在需要跳转的控制器里面添加头文件#import
2:实现代理SKStoreProductViewControllerDelegate
3:- (void)evaluate{
//初始化控制器
SKStoreProductViewController *storeProductViewContorller = [[SKStoreProductViewController alloc] init];
//设置代理请求为当前控制器本身
storeProductViewContorller.delegate = self;
//加载一个新的视图展示
[storeProductViewContorller loadProductWithParameters:
//appId唯一的
@{SKStoreProductParameterITunesItemIdentifier : @'587767923'} completionBlock:^(BOOL result, NSError *error) {
//block回调
if(error){
NSLog(@'error %@ with userInfo %@',error,[error userInfo]);
}else{
//模态弹出appstore
[self presentViewController:storeProductViewContorller animated:YES completion:^{
}];
}
}];
}
//取消按钮监听
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{
[self dismissViewControllerAnimated:YES completion:^{
}];
}
