iOS谷歌login查看丢失的导航栏和底部栏

@interface GooglePlusManager() <GIDSignInDelegate,GIDSignInUIDelegate> @property (nonatomic, strong) GIDSignIn *gppSignIn; @property (nonatomic, weak) UIViewController * localVC; @end @implementation TWNGooglePlusManager (void)doGooglePlusLogin: (UIViewController *)viewController { [self setPropertiesToInitialState]; NSString* clientId = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"GoogleClientId"]; self.gppSignIn = [GIDSignIn sharedInstance]; [self.gppSignIn setClientID:clientId]; if (self.gppSignIn) { self.gppSignIn.scopes = @[ @"profile", @"email" ]; [self.gppSignIn setDelegate:self]; self.localVC = viewController; [self.gppSignIn setUiDelegate:self]; self.gppSignIn.allowsSignInWithWebView = YES; [self.gppSignIn signIn]; } } #pragma mark - GIDSignInUiDelegate (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController { [self.localVC presentViewController:viewController animated:YES completion:nil]; } @end 

基本上，GIDSignIn是在我的GooglePlusManager中，我将当前SignIN ViewController传递给GooglePlusManager，一切工作正常，除了login页面没有后退/取消button。 我曾尝试setUiDelegate自己或VC，结果是一样的。 发生在真正的9.0设备和9.1模拟器。

找出答案是我错过了SafariServices.framework。 在将SafariServices.framework链接到应用程序后，其工作正常。
