AppDelegate

StoryBoard获取不同id的Controller

ViewController *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"list"];

获取plist文件中数据

    NSString *plistPath = [bundle pathForResource:@"team" ofType:@"plist"];

    // 获取属性列表文件中的全部数据
    self.listTeams = [[NSArray alloc] initWithContentsOfFile:plistPath];
