Since Xcode6, the default is to create storyboard instead of xib files, and as a beginner, it is important to understand how xib is loaded, so you need to create a project without storyboard
1. Create a new project
2. Select a template for only one view
Select Single View application and click Next
3. Fill in the project information
No need to select core data, after filling out the information, click Next, then click Create
4. Delete Storyboard and launchscreen.xib files
Throw storyboard and Launchscreen into the wastebasket.
5. Modify the Info.plist file
Delete info.plist files in main storyboard file base name and launch screen interface file base name two properties
6. Create a user interface view Xib file
Click Next, then save as "Helloworldview" click Create
Drag a lable from the object library and drag a button to form the following diagram
7. Modify the View controller file
Creating an association between a view and a controller, Xcode creates the ViewController.h and VIEWCONTROLLER.M files by default, so you don't have to create your own
1) Modify the file ' s Owner of the Xib view
Click File ' Owner in the list, press Command+option+3 to open the Identity Inspector, modify the class in the custom class to Viewcontroller
2) Create an export and action Method Association
Click the two circle in the middle to open the auxiliary editor
Select lable View and Control-drag to ViewController.h @interface and @end pop-up menu, follow fill in, then enter to create export
The action method that creates the button is also the selected view and the Controll key is dragged to the secondary edit area
Once the association is created, the ViewController.h code becomes:
1 #import <uikit/uikit.h>2 3 @interface viewcontroller:uiviewcontroller4 @property (weak, nonatomic) Iboutlet Uila Bel *hellolable;5-(Ibaction) Hellobutton: (UIButton *) sender;6 7 @end
Click File's Owner in the Xib list, and then press COMMAND+OPTION+6 to open Connection Inspector View the connection to the output and the action, Associating view with the View property inherited from Viewcontroller from Uiviewcontroller
The associated connection checker is as follows
3) Modify the VIEWCONTROLLER.M code
1 #import "ViewController.h" 2 3 @interface Viewcontroller () 4 5 @end 6 7 @implementation Viewcontroller 8
9-(void) Viewdidload {ten [super viewdidload];11 //Do any additional setup after loading the view, typically FR Om a nib.12 }14-(void) didreceivememorywarning { [super didreceivememorywarning];17 //Dispose of an Y resources that can be recreated.18}19-(ibaction) Hellobutton: (UIButton *) Senhder {self.helloLable.frame = CG Rectmake (Ten, +, +); Self.helloLable.text = @ "Hello world!"; }24 @end
8. Modify the APPDELEGATE.M file
The following code already exists in the AppDelegate.h file created by Xcode by default:
1 #import <uikit/uikit.h>2 3 @interface appdelegate:uiresponder <uiapplicationdelegate>4 5 @property (Stron G, nonatomic) UIWindow *window;6 7 @end
Xcode creates the properties of the window by default for the app delegate, opens the APPDLEGATE.M file, and introduces the ViewController.h
Rewrite APPDLEGATE.M file -(BOOL) Application: (uiapplication *) application Didfinishlaunchingwithoptions: (nsdictionary *) Launchoptions method
Other code is not modified, the code is as follows
1 #import "AppDelegate.h" 2 #import "ViewController.h" 3 @interface appdelegate () 4 5 @end 6 7 @implementation Ap Pdelegate 8 9-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions {One //Override point for customization after application launch.12 //create WINDOW13 Self.window = [[UIWindow alloc] Initwithframe:[[uiscreen mainscreen] bounds]];14 //Create Viewcontroller instance viewcontroller * Viewcontroller = [[Viewcontroller alloc] initwithnibname:@ "Helloworldview" bundle:nil];16 //Set window root View Controller 17 Self.window.rootViewController = viewcontroller;18 self.window.backgroundColor = [Uicolor whitecolor];19 [Self.window makekeyandvisible];20 return yes;21}
9. Running the program
