问题描述
I get the following error in my console:
Applications are expected to have a root view controller at the end of application launch
Below is my application:didFinishLaunchWithOptions method:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Set Background Color/Pattern
self.window.backgroundColor = [UIColor blackColor];
self.tabBarController.tabBar.backgroundColor = [UIColor clearColor];
//self.window.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"testbg.png"]];
// Set StatusBar Color
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
// Add the tab bar controller's current view as a subview of the window
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
In Interface Builder, the UITabBarController's delegate is hooked up to the App Delegate.
Anyone know how to fix this issue?
解决方案
Replace in AppDelegate
[window addSubview:[someController view]];
to
[self.window setRootViewController:someController];
