IOS--純程式碼方式編寫View

標籤：

AppDelegate:

 1 #import "AppDelegate.h" 2 #import "TestController.h" 3  4 @interface AppDelegate () 5 @property(nonatomic,strong)TestController *controller; 6 @end 7  8 @implementation AppDelegate 9 10 11 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {12     // Override point for customization after application launch.13     self.window = [[UIWindow alloc]init];14 15     self.controller = [[TestController alloc]init];16 17     self.window.rootViewController = self.controller;18     19     [self.window makeKeyAndVisible];20     return YES;21 }

TestController:

 1 #import "TestController.h" 2 #import "RootView.h" 3  4 @interface TestController() 5  6 @property(nonatomic,strong)RootView *rootView; 7  8 @end 9 10 @implementation TestController11 12 - (void)viewDidLoad13 {14     [super viewDidLoad];15     16     self.rootView = [[RootView alloc]initWithFrame:[[UIScreen mainScreen]bounds]];17     self.view = self.rootView;18 }19 20 @end

RootView 繼承 UIView

 1 #import "RootView.h" 2  3 @interface RootView() 4  5 @end 6  7 @implementation RootView 8  9 -(instancetype)initWithFrame:(CGRect)frame10 {11     self = [super initWithFrame:frame];12     if (self) {13         self.backgroundColor = [UIColor blueColor];14     }15     return self;16 }17 18 @end
