TabController.h:
#import <UIKit/UIKit.h> @interface TabController : UITabBarController <UITabBarControllerDelegate> @end
TabController.m:
#import "TabController.h" @interface TabController () @end @implementation TabController - (void)viewDidLoad { [super viewDidLoad]; self.delegate = self; } - (void)viewWillLayoutSubviews { [super viewWillLayoutSubviews]; [self.tabBar invalidateIntrinsicContentSize]; CGFloat tabSize = 44.0; UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if (UIInterfaceOrientationIsLandscape(orientation)) { tabSize = 32.0; } CGRect tabFrame = self.tabBar.frame; tabFrame.size.height = tabSize; tabFrame.origin.y = self.view.frame.origin.y; self.tabBar.frame = tabFrame; // Set the translucent property to NO then back to YES to // force the UITabBar to reblur,otherwise part of the // new frame will be completely transparent if we rotate // from a landscape orientation to a portrait orientation. self.tabBar.translucent = NO; self.tabBar.translucent = YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end
