(1) 2 ways to set the status bar--The first way is that we set in the controller, the system by default is given to the view controller to manage, so different view controllers can customize the different status bar as follows:-(BOOL) prefersstatusbarhidden{}-(Uistatusbarstyle) preferredstatusbarstyle{}--if we need to give UIApplication object Management (IOS6 before), you need the following settings:Change the default settings in Info.plist first:The

The lifecycle of an iOS application, and whether the program is running in the foreground or in the background, transforms the state of the application, which is important to the developer. The resources for iOS systems are limited, and applications are not the same in the foreground and in the background. In the background, the program is subject to many limitations of the system, which can improve battery usage and user experience.1. Status of the applicationNot running running program does no

IOS network push notification Push notifications are initiated by application service providers and sent to the application client through Apple's APNs (Apple Push Notification Server. The process of pushing notifications can be divided into the following steps:The application service provider sends the message and device token to Apple's APNs server from the server side.APNs searches for the corresponding device on the registered device (iPhone, iPad, iTouch, mac, etc.) based on the device toke

daemon in the background and can execute code, most of the program into this state will stay in this state for a while. The time will then go into the suspended state (Suspended). Some programs after a special request can be long-term in the Backgroud state//suspended suspend program in the background can not execute code. The system automatically turns the program into this state and does not give notice. When suspended, the program is still in memory, when the system memory is low, the system

1. Each application has its own Uiwindow,uiwindow inherited from the Uiview2.uiview face problem: 1. Who controls the switch between UIView? 2. Who manages the UIView life cycle? 3. Who will assemble the data for UIView? 4. Who listens to UIView's events? The answers to the above three questions are: UiviewcontrolleriOS Core class UIView: Views, things that can be seen and touched on the screen are UIView, such as buttons, text labels, tables Uiviewcontroller: Internal default has a

The following three types of events are available:1. Touchscreen events (Touch event)2, motion events (motion event)3. Rem

A long time ago to write the demo, now remember the next ~ ~ ~ may be a mistakeGithub:https://github.com/bigshow1949/yfpushtestSteps:1) Add App ID.Apple Developer Center: Identifiers--->app IDs to add an ID, such as my name:yfpushtest, where the ID must be the project bundle Identifier, such as: com. YFPushTest.BigShow.YFPushTest;2) Generate Apple Push certificate (production test)Named for example: COM. YFPushTest.BigShow.YFPushTest, choose the app ID, to choose the one we just created, do not

1) iOS Core class UIView view, what you can see on the screen is a view, such as: Buttons, text labels, tables, etc. Uiviewcontroller: The internal default has a view (UIView) that is responsible for managing the UIView lifecycle, assembling data to display on UIView, and handling its events iOS with MVC mode: Model-view-controller 2) Operation Process How iOS Works 1.
