IOS初始化控制器的实现方法总结
一.ViewControllViewController方法
#import "AppDelegate.h" #import "ViewController.h" @interface AppDelegate () @property(nonatomic,strong) ViewController *viewController; @end @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //初始化控制器 self.viewController = [[ViewController alloc]init]; //初始化window self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds]; //设置控制器 self.window.rootViewController = self.viewController; return YES; }
二 .ViewControllViewController 与 xib方法
#import "AppDelegate.h" #import "XibViewControllViewController.h" @interface AppDelegate () @property(nonatomic,strong) ViewController *viewController; @property(nonatomic,strong) XibViewControllViewController *xibControllViewController; @end @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //初始化控制器 self.xibControllViewController = [[XibViewControllViewController alloc]initWithNibName:@"XibViewControllViewController" bundle:nil]; //初始化window self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds]; //设置控制器 self.window.rootViewController = self.xibControllViewController; return YES; }
