我在AppDelegate類中創建了一個TabBar VC,通過[[UIScreen mainScreen]邊界]設置窗口框架。由於我有一個狀態欄顯示,高度應該是460,但它似乎是480.如果我手動將高度設置爲460,它會將觸摸識別切割到標籤底部。下面是代碼爲什麼當applicationFrame高度爲460時窗口480的高度?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIColor *brownNavBarColor = [[UIColor alloc] initWithRed:0.78f green:0.56f blue:0.06f alpha:1.0f];
[application setStatusBarHidden:NO];
CGRect windowRect = [[UIScreen mainScreen] bounds];
self.window = [[UIWindow alloc] initWithFrame:windowRect];
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
NSLog(@" appFrame %f", appFrame.origin.y);
NSLog(@" appFrame %f", appFrame.size.height);
NSLog(@" window.frame %f", self.window.frame.origin.y);
NSLog(@" window.frame %f", self.window.frame.size.height);
NSLog(@" window.bounds %f", self.window.bounds.origin.y);
NSLog(@" window.bounds %f", self.window.bounds.size.height);
[self.window makeKeyAndVisible];
self.ingredientTabVC2 = [[NewIngredientViewController alloc] initWithNibName:nil bundle:NULL];
self.ingredientNC2 = [[UINavigationController alloc] initWithRootViewController:self.ingredientTabVC2];
[self.ingredientNC2.navigationBar setTintColor:brownNavBarColor];
self.ingredientTabVC3 = [[IngredientTabViewController alloc] initWithNibName:nil bundle:NULL];
self.ingredientNC3 = [[UINavigationController alloc] initWithRootViewController:self.ingredientTabVC3];
[self.ingredientNC3.navigationBar setTintColor:brownNavBarColor];
self.tabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:NULL];
self.tabBarController.viewControllers = [[NSArray alloc] initWithObjects: self.ingredientNC2, self.ingredientNC3, nil];
[self.window setRootViewController:self.tabBarController];
return YES;
}
這使日誌輸出

有人能解釋這種差異背後的原因是什麼?
