关于IQKeyboardManager 在iOS11导航栏消失的问题
问题: 升级到iOS11之后点击键盘时导航栏消失 如下图:
使用版本:pod 'IQKeyboardManager', '~> 5.0.6'
问题原因:IQKeyboardManager 在获取当前顶层控制器的时候获取到了tabBarController
解决办法:
找到IQUIView_Hierarchy.m 修改-(UIViewController *)topMostController方法 如下:即可
- -(UIViewController *)topMostController{
- UIViewController *rootController = [UIApplication sharedApplication].keyWindow.rootViewController;
- if([rootController isKindOfClass:[UITabBarController class]]){
- UITabBarController *tabBarController = (UITabBarController *)rootController;
- UINavigationController *selectController = tabBarController.selectedViewController;
- UIViewController *viewController = (UIViewController *)selectController.visibleViewController;
- while (viewController.presentedViewController) {
- viewController = (UIViewController *)viewController.presentedViewController;
- }
- return viewController;
- }else if ([rootController isKindOfClass:[UINavigationController class]]) {
- UINavigationController *selectController = (UINavigationController *)rootController;
- return selectController.visibleViewController;
- }else if ([rootController isKindOfClass:[UIViewController class]]) {
- return rootController;
- }
- else{
- return nil;
- }
- }
