UIViews ending up beneath tab bar

Question

In my app, I aligned a label the standard amount from the bottomLayoutGuide using autolayout. When the app first starts everything is layed out as I wanted but when I switch

Answer 1

Calling setNeedsLayout is all that needs to be done. This essentially patches the framework bug. It needs to be called on the UITabBarController view itself when a new view is selected. Create a delegate for the app's tab bar controller. and put this in the delegate object:

@interface MyPatch : NSObject 

@end

@implementation MyPatch

-(void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
    [tabBarController.view setNeedsLayout];
}

@end

And initialize it wherever you want... something like this:

@interface AppDelegate : UIResponder 
{
         MyPatch *patch;

}

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    patch=[MyPatch new];
    myTabBarController.delegate=patch;
}

@end
