拷贝的一个项目运行报错:
2017-03-07 14:44:57.906 Zenithcp[54472:2455909] *** Assertion failure in -[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3600.5.2/UIApplication.m:3679
错误原因:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];//自定义了window,但是没有设置rootViewController
[self.window makeKeyAndVisible];
[self.window.rootViewController presentViewController:surfboard animated:NO completion:nil];
return YES;
}
解决方式:设置window的rootViewController即可
UINavigationController *indexViewCr=[[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"Nav"];
keyWindow.rootViewController = indexViewCr;
