1、米有xib,storyboard，只有.h和.m文件

2、在AppDelegate中，要跳转页面，需要初始化当前ViewController的NavigationController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

// Override point for customization after application launch.

//一下三步，为了去掉storyboard；点击项目，将main interface值置为空

//设置全屏

self.window = [[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds];

/**将自己的默认启动ViewController设为根视图**/

//app入口Viewcontroller

ViewController * vc =[[ViewControlleralloc]init];

UINavigationController * nav =[[UINavigationControlleralloc] initWithRootViewController:vc];

self.window.rootViewController = nav;

//显示

[self.windowmakeKeyAndVisible];

returnYES;

}

3、初始化UIButton：

UIButton *mBtn = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

[mBtn setFrame:CGRectMake(50,50, 100,100)];

[mBtn setTitle:@"页面跳转" forState:UIControlStateNormal];

[mBtn addTarget:selfaction:@selector(onClick:)forControlEvents:UIControlEventTouchUpInside];

[self.viewaddSubview:mBtn];

4、监听

-(void)onClick:(UIButton *)a

{

NSLog(@"touch down");

DrawViewController *vController = [[DrawViewController alloc] init];

[self.navigationController pushViewController:vController animated:true];

}
