1.1Segue 连线跳转

• 明确跳转源头：明确地知道跳转动作是由哪个控件触发的
• 不明确跳转源头：无法确定跳转动作是由哪个控件触发的，只是可以确定当前界面是要跳转到另外一个界面

1.2跳转到故事板中独立的控制器

1.3从故事板中跳转到xib创建的控制器中

1.4跳转到其他故事板

ViewController.m

#import "ViewController.h"
#import "xibViewController.h"
@interface ViewController ()
@end
@implementation ViewController
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
  //跳转到蓝色界面
  //不明确跳转源头
    [self performSegueWithIdentifier:@"gotoBVC" sender:nil];
}
- (IBAction)gotoOtherVc:(id)sender {
    UIViewController *otherVC = [self.storyboard instantiateViewControllerWithIdentifier:@"otherVC"];
    [self presentViewController:otherVC animated:YES completion:nil];    
}
- (IBAction)gotoXibVc:(id)sender {
    [self presentViewController:[[xibViewController alloc]initWithNibName:@"xibViewController" bundle:nil] animated:YES completion:nil];
}
- (IBAction)gotoOtherStoryBoard:(id)sender {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"other" bundle:nil];//bundle文件夹路径，bundle:nil默认为当前路径
    //跳转其他故事板中 指定的 控制器中
    UIViewController *vc =[storyboard instantiateViewControllerWithIdentifier:@"blueVC"];
    //跳转到其他故事板中 初始的 控制器中
    //UIViewController *vc = [storyboard instantiateInitialViewController];
    [self presentViewController:vc animated:YES completion:nil];
}

BlueViewController.m

@implementation BlueViewController
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    [self dismissViewControllerAnimated:YES completion:nil];
}
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}
