Application startup Principles in iOSSource: http://m.warting.com/program/201601/127355.htmlFirst, UIApplication1. Brief introduction(1) The UIApplication object is a symbol of the application, and a UIApplication object represents an application.(2) Each application has its own UIApplication object, and is a singleton, if you try to create a new

After the application is created, the AppDelegate.h file and the APPDELEGATE.M file are default.What is Appdelegate? Appdelegate is a proxy for the entire application, providing a similar monitoring interface for program startup, exit, and so on.APPDELEGATE.Mthe file where the interface is located, common interfaces are:Application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions//the delegate call to execute after the application is startedApplicationwillresignactive: (

The iphone application is initiated by the main function main, which is responsible for invoking the Uiapplicationmain function, as shown in the following form: int uiapplicationmain (int argc, char *argv[], NSString *Principalclassname, NSString *delegateclassname); So what exactly does the Uiapplicationmain function do? This function is mainly responsible for three things:1) Initializes the application object from the given class name, which is an instance of initializing the

In a program, you can call an application that comes with the system. For example, when I enter the program, I want to directly call Safar to open a webpage. Below is a simple usage: -(Bool) Application :( uiapplication *) Application didfinishlaunchingwitexceptions :( nsdictionary *) launchoptions {self. window = [[[uiwindow alloc] initwithframe: [uiscreen mainscreen] bounds] autorelease]; self. viewcontroller = [[[viewcontroller alloc] initwithnibna

class at load time, using this technique to add another Dylib class method without changing the dylib, rather than the usual way to change a class by defining a category.The dependencies of the master execution file and the associated dylib form a huge graph of the graphs, the execution initializer loads the leaf nodes first, and then progressively loads the intermediate nodes up until the root node is loaded at last. This loading order ensures security, and the rest of the dylib files that it
