使用 Apptentive 时无法识别的选择器:-[ATAppRatingFlow appDidLaunch:viewC

Question

由于无法

识别的选择器，在应用API中调用以下方法崩溃。

ATAppRatingFlow *ratingFlow = [ATAppRatingFlow sharedRatingFlowWithAppID:kApptentiveAppID];
[ratingFlow appDidLaunch:YES viewController:self.navigationController];

这将产生以下错误日志：

*2013-10-03 10:32:08.089 YourApp[39841:a0b] -[ATAppRatingFlow appDidLaunch:viewController:]: unrecognized selector sent to instance 0xc5aee60*

以前版本的 Apptentive 使用以下 3 种方法来显示评级流程：

- (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，它们已被单个方法取代：

- (void)showRatingFlowFromViewControllerIfConditionsAreMet:(UIViewController *)viewController;

这样称呼它：

[[ATAppRatingFlow sharedRatingFlow] showRatingFlowFromViewControllerIfConditionsAreMet:viewController];

仅当用户此时满足评分条件（在 Apptentive 网站上设置）时，showRatingFlowFromViewControllerIfConditionsAreMet 方法才会显示评分流。
