Original: http://blog.csdn.net/huifeidexin_1/article/details/7792371The 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

In many cases, we do not need to care about this class. We seldom inherit this class and occasionally call the APIs of this class to implement some functions, but it is undeniable that, this class is a very important concept in IOS programming. So I will write this article here to summarize the information of this class. If something is wrong, leave a message. Thank you. The core function of uiapplication is to provide control and collaborative work d

Since contact with iOS soon, although the project can be done, but for uiapplication, appdelegate These concepts are not very familiar with, this morning to summarize, find a good blog post, I share it.

1. What is UIApplication The uiapplication object is symbolic of the application, cannot be created manually, cannot alloc init, and an application allows only one . Each app has its own uiapplication object, and it's a singleton . 　　This singleton object can be obtained by [uiapplication shareapplica

If you do not want the IPhone to enter the lock screen standby when the app is running, add the following line of code[[UIApplication sharedapplication] setidletimerdisabled:yes];By the way, learning the nextuiapplication. The iphone application is initiated by main function main, which is responsible for invokingUiapplicationmainfunction, the form of the function is as follows:Align Uiapplicationmain, option+ mouse click. can be viewed.So what exactl

uiapplication Simple to understand literally is the application, development time will sometimes call the method in the way, it looks inconspicuous, the actual iOS development UIApplication provides control and collaboration during the operation of the iOS program. Each application must have only one instance of UIApplication (or its subclasses) at run time, whic

UIApplication in-depth researchMany times, we do not need to care about this class, we rarely inherit this class, occasionally call this class API to implement some functions, but admittedly, this class is an important concept in iOS programming, so I write this article here to summarize the following information about this class, if the wrong place, please leave a message, thank you.The core role of UIApplication
