IOS初始化控制器的实现方法总结
IOS初始化控制器的实现方法总结
一.ViewControllViewController方法
#import"AppDelegate.h" #import"ViewController.h" @interfaceAppDelegate() @property(nonatomic,strong)ViewController*viewController; @end @implementationAppDelegate -(BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions{ //初始化控制器 self.viewController=[[ViewControlleralloc]init]; //初始化window self.window=[[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds]; //设置控制器 self.window.rootViewController=self.viewController; returnYES; }
二.ViewControllViewController与xib方法
#import"AppDelegate.h" #import"XibViewControllViewController.h" @interfaceAppDelegate() @property(nonatomic,strong)ViewController*viewController; @property(nonatomic,strong)XibViewControllViewController*xibControllViewController; @end @implementationAppDelegate -(BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions{ //初始化控制器 self.xibControllViewController=[[XibViewControllViewControlleralloc]initWithNibName:@"XibViewControllViewController"bundle:nil]; //初始化window self.window=[[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds]; //设置控制器 self.window.rootViewController=self.xibControllViewController; returnYES; }
