ios界面切换

1.新建Cocos Touch文件，继承自  ViewController，  假设文件名为 MyViewController

2.在 storyboard中添加新的view controller，并指定实现类是MyViewController，同时为该view controller指定id为 vc2



3.为view controller 1中的按钮添加点击事件

#import "ViewController.h"
#import "MyViewController.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (IBAction)two:(id)sender {

//根据刚才指定的VC2去找对应viewController
  MyViewController* my= [self.storyboard instantiateViewControllerWithIdentifier:@"vc2"];

[self presentViewController:my animated:YES completion:^{

NSLog(@"开启了");

}];

}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

@end
