, such as the life cycle of the application, event handling, etc. So here's a look at the Appdelegate class: 　　 In this class we can see a lot of timing callbacks, which are associated with the application's life cycle approach, and here we analyze the callback timing of these methods: 　　 1.

First, a brief introduction iphone applications usually have only one window, represented as an instance of a UIWindow class. The application creates this window at startup (or from a nib file) and adds one or more views to the window and displays it. After that we rarely need to refer to it again. The UIWindow object is the root of all UIView, the display of managed and coordinated applications. A generic application has only one UIWindow object, and even if there are multiple UIWindow objects

1. When the program starts every time you receive a push or the program does not start by pushing the message to start the program, will trigger the Appdelegate inside the method (note to the server with the certificate has been, such as the development environment, the server will also use the development certificate of the PEM to do): -(void) Application: (UIApplication *) application didreceiveremotenotification: (nsdictionary *) userInfo { Here

The principle of push:The working mechanism of push can be simply summed up as: provider refers to the push server for an iphone software, which I will use. NET as a provider. APNS is an abbreviation for Apple push Notification Service (Apple push server) and is Apple's server. Can be divided into three stages. First stage: The Push server application packages the message to be sent, the identity of the iphone, and sends it to APNS. Phase II: APNs in its own list of iphone's registered push serv

iOS Development UI Chapter-uiwindow Brief IntroductionFirst, Brief introductionUIWindow is a special kind of uiview that usually has only one uiwindow in an app.After the iOS program starts, the first view control created is UIWindow, then the controller's view is created, the controller's view is added to the UIWindow, and the controller's view is displayed on the screen.An iOS program can be displayed on the screen entirely because it has uiwindow. It says that without UIWindow, you can't see

Diagram The iOS program life cycleAfter the application starts, there are 5 states of active, Inactive, Background, Suspended, not running , and several state transitions are shown:When the app state changes, the callback function is implemented in Appdelegate, and the system executes the corresponding callback when the app status changes:-(BOOL) Application: (UIApplication *) application willfinishlaunchingwithoptions: (nsdictionary *) launchOptions

Question 1: What events are there in IOS? • Various events are generated when a user uses an app. • Events in IOS can be divided into three major types. Question 2: What is a responder object? • In iOS, not all objects can process events. Only objects that inherit uiresponder can receive and process events. We call it "responder object". • uiapplication, uiviewcontroller, and uiview all inherit from uiresponder. Therefore, they are all responder objec

third line shows that Test2dAppDelegate implements the system-defined application interface UIApplicationDelegate. Various system events to be handled by the current application: Give up control: applicationWillResignActive quit Get control: applicationDidBecomeActive role Memory alert: applicationDidReceiveMemoryWarning alert Application exit prompt: applicationWillTerminate quit System time change: applicationSignificantTimeChange // Give up control (Void) applicationWillResignActive :

enter this state, they will stay in this state for a while. after the time is reached, it will be Suspended ). some programs can be in the Background state for a long time after special requests. The sushortded (Suspended) program cannot execute code in the background. The system will automatically change the program to this State and no notification will be sent. When Suspended, the program will remain in the memory, and when the program memory Application Status Lifecycle This method is call

How does swift add messages to the IOS app icon and add swiftios You can add a Message count reminder in the upper-right corner of the application icon to conveniently notify you of any new messages to be processed in the application.
