We used UILabel to display text, but in UILabel, when the text length exceeds the display area, the scroll bar cannot be displayed. However, we can use UITextView to easily do this, I would like to share with you the following: The Code is as follows: HHLAppDelegate. h #import @class HHLViewController;@interface HHLAppDelegate : UIResponder @property (strong, nonatomic) UIWindow *window;@property (strong, nonatomic) HHLViewController *viewController;@end HHLAppDelegate. m #im

interrupt application will release all sockets, including the socket used to connect to the VoIP service. Therefore, when the program runs, it needs to create the socket from scratch.C, in order to prevent disconnection, VoIP programs need to be periodically awakened to check its services. To make this behavior easier, iOS creates a special handle by using the (UIApplication Setkeepalivetimeout:handler:) method. You can create the handle in the Appli

We send a message to the object to initiate a specific action. When the object sends some changes, it notifies us through the callback function. When a specific event occurs, the object calls the corresponding callback function to trigger the business logic. The callback function is implemented through the so-called delegation. Delegate ------- benefits: It separates the logic processing of the program from the uiapplication more concisely. It avoi

UIApplicationMain for relevant processing. The parameter contains information about when an application starts from the system. These parameters are parsed by the UIKit infrastructure, otherwise they are negligible. PrincipalClassName: this parameter identifies the name of the application class (this class must inherit from the UIApplication class ). This is the class responsible for running the application. We recommend that you use nil for this par
