由于选择器无法识别，在Apptentive API中调用以下方法会崩溃。
ATAppRatingFlow *ratingFlow = [ATAppRatingFlow sharedRatingFlowWithAppID:kApptentiveAppID];
[ratingFlow appDidLaunch:YES viewController:self.navigationController];
产生以下错误日志:
*2013-10-03 10:32:08.089 YourApp[39841:a0b] -[ATAppRatingFlow appDidLaunch:viewController:]: unrecognized selector sent to instance 0xc5aee60*

最佳答案
先前版本的Apptentive使用以下3种方法来显示评分流程:
- (void)appDidLaunch:(BOOL)canPromptForRating viewController:(UIViewController *)viewController;
- (void)appDidEnterForeground:(BOOL)canPromptForRating viewController:(UIViewController *)viewController;
- (void)userDidPerformSignificantEvent:(BOOL)canPromptForRating viewController:(UIViewController *)viewController;
在较新版本的应用程序中，它们已由一种方法替换:
- (void)showRatingFlowFromViewControllerIfConditionsAreMet:(UIViewController *)viewController;
这样称呼它:
[[ATAppRatingFlow sharedRatingFlow] showRatingFlowFromViewControllerIfConditionsAreMet:viewController];
如果此时达到了您的评分条件(在Apptentive网站上设置)，
showRatingFlowFromViewControllerIfConditionsAreMet方法将仅显示评分流。
