问题 I'm trying to declare another window in MyThing.m @property (nonatomic, strong) UIWindow *window; But get this error Illegal redeclaration of property in class extension "MyThing" (attribute must be 'readwrite', while its primary must be 'readonly') If I rename window to something else, it is OK. Why is that? Is window meant to be declared once in the AppDelegate.h ? 回答1: I figure out the problem, it has nothing to do with the window property declared in AppDelegate.h The problem is MyThing

The result is to have each feed load as soon as it is called or have them load asynchronously - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { // Override point for customization after application launch. // make RSS call JSTRRSSReader *reader = [[JSTRRSSReader alloc] init];

问题 After a bit of bungling I have added a reveal view controller to my app but now it doesn't seem to be loading the data. I can't see where my changes would have affected that aspect of the app. in didFinishLaunchingWithOptions I changed STRTableViewController *tableViewController = [(UINavigationController *)self.window.rootViewController viewControllers][0]; self.delegate = tableViewController; to the following since the rootViewController is no longer the table view: // in .m interface

问题 I'm trying to pass text form one TextField to another TextField. Both of them are located in different ContainerViews. Users can switch between different ContainerViews by Segmented Control (thus, all my ContainerView are located inside of the ViewController with Segmented Control).

问题 I am trying to read the Pasteboard for 5 times in the applicatioDidEnterBackground section of the AppDelegate. To print the string I use print(UIPasteboard.general.string!) but it works only into the function and it doesn't in the other nested functions. Let me explain: func applicationDidEnterBackground(_ application: UIApplication) { // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application
